Prevalence and Incidence of Mood Disorders
Mood disorders, including major depressive disorder (MDD), bipolar disorder, and dysthymia, are among the most prevalent mental health conditions globally. Their prevalence and incidence vary based on factors such as geographic location, socioeconomic status, and access to mental health care.
1. Prevalence of Mood Disorders
Prevalence refers to the total number of cases (both new and existing) of a condition in a population at a specific time.
Global Prevalence of Depression
According to the World Health Organization (WHO), depression affects approximately 280 million people worldwide.
The lifetime prevalence of major depressive disorder (MDD) is estimated to be around 10-20% in the general population.
Women are nearly twice as likely as men to experience depression.
Global Prevalence of Bipolar Disorder
The lifetime prevalence of bipolar disorder is around 1-2% globally.
Bipolar disorder type I has a lifetime prevalence of 0.6%, while bipolar disorder type II is around 0.4%.
It affects both genders equally, but the onset is typically earlier in males.
Dysthymia (Persistent Depressive Disorder)
Affects 1-5% of the population, often starting in early adulthood.
More common in women than men.
Mood Disorders in Children and Adolescents
Prevalence of depression in adolescents is around 13-17%.
Bipolar disorder affects approximately 1% of adolescents.
Mood Disorders in Elderly
Depression in the elderly is common but underdiagnosed, affecting about 10-15% of individuals above 60 years.
2. Incidence of Mood Disorders
Incidence refers to the number of new cases that develop in a population over a specific period.
Depression:
The annual incidence rate of major depressive disorder (MDD) is estimated to be 3-5% worldwide.
First-time episodes of depression occur mostly between 15-29 years of age.
Bipolar Disorder:
The annual incidence of bipolar disorder is approximately 0.5-1%.
The first manic or depressive episode typically appears between 15-25 years of age.
Suicide Risk in Mood Disorders
Individuals with major depressive disorder have a 15% lifetime risk of suicide.
Suicide risk in bipolar disorder is significantly higher, especially during depressive episodes.
3. Factors Influencing Prevalence and Incidence
Several factors contribute to the varying prevalence and incidence rates of mood disorders:
Genetic factors – Family history increases the risk of mood disorders.
Environmental stressors – Trauma, abuse, or chronic stress can trigger mood disorders.
Socioeconomic status – Poverty, unemployment, and lack of social support increase risk.
Gender differences – Women are more prone to depression due to hormonal and social factors.
Access to mental health care – Early diagnosis and treatment impact reported prevalence.
4. Regional Variations in Mood Disorders
High-income countries tend to report higher prevalence due to better diagnosis and mental health awareness.
Low- and middle-income countries (LMICs) may have underreported cases due to stigma and lack of mental health infrastructure.
Countries with political instability, conflict, or economic crises show an increase in depression and anxiety disorders.
Types of Abnormal Mood or Affect
Mood and affect are essential components of emotional expression and regulation. Mood refers to a person’s sustained emotional state, while affect is the observable expression of emotions at a given moment. In various psychiatric and neurological conditions, mood and affect can become abnormal, leading to disruptions in emotional regulation and social interactions. Below is a detailed classification of abnormal mood and affect types.
1. Types of Abnormal Mood
Abnormal moods refer to persistent emotional states that deviate from normal functioning and may indicate underlying psychiatric disorders.
A. Depressed Mood
Persistent sadness, hopelessness, or emptiness.
Common in major depressive disorder, persistent depressive disorder (dysthymia), and adjustment disorder with depressed mood.
May include low energy, reduced motivation, and suicidal thoughts.
B. Elevated Mood
Unusually high, exaggerated, or euphoric mood.
Seen in mania or hypomania (bipolar disorder).
Characterized by increased energy, grandiosity, rapid speech, and impulsive behavior.
C. Expansive Mood
Overly enthusiastic or exaggerated emotional expression beyond normal limits.
Seen in manic episodes of bipolar disorder.
The person may lack social restraint and have an inflated sense of self-importance.
D. Irritable Mood
Easily annoyed, angered, or frustrated over minor stimuli.
Seen in bipolar disorder, major depressive disorder (MDD), intermittent explosive disorder, and some personality disorders.
Common in children with mood dysregulation disorders.
E. Anxious Mood
Persistent excessive worry, fear, or nervousness.
Seen in generalized anxiety disorder (GAD), panic disorder, and post-traumatic stress disorder (PTSD).
Often accompanied by muscle tension, restlessness, and sleep disturbances.
F. Dysphoric Mood
Generalized dissatisfaction, unease, or emotional discomfort.
Seen in depressive disorders, substance withdrawal, and some personality disorders.
Accompanied by irritability, low motivation, and anxiety.
G. Labile Mood
Sudden, intense, and unpredictable mood shifts.
Seen in bipolar disorder, borderline personality disorder (BPD), and neurological disorders (e.g., traumatic brain injury, multiple sclerosis).
Mood swings can be extreme and inappropriate for the situation.
H. Apathy (Blunted Mood)
Lack of interest, motivation, or emotional responsiveness.
Seen in schizophrenia, severe depression, Parkinson’s disease, and dementia.
The person appears indifferent to personal or social events.
2. Types of Abnormal Affect
Affect refers to the external display of emotions, which can become inappropriate, blunted, or exaggerated in certain psychiatric and neurological conditions.
A. Flat Affect
Complete absence or severe reduction of emotional expression.
Seen in schizophrenia, severe depression, and Parkinson’s disease.
The person may appear emotionally “blank,” with little facial or vocal expression.
B. Blunted Affect
Significant reduction in emotional expression but not completely absent.
Common in schizophrenia, depression, and dementia.
The person may show minimal facial expressions, monotone speech, and reduced gestures.
C. Restricted Affect
Limited range of emotional expression, less than normal but more than blunted affect.
Seen in some mood disorders, PTSD, and chronic stress conditions.
The person shows narrowed emotional responses and difficulty expressing strong emotions.
D. Labile Affect
Rapid, exaggerated, and inappropriate emotional shifts.
Seen in bipolar disorder, borderline personality disorder (BPD), and pseudobulbar affect (PBA).
The person may suddenly cry, laugh, or become angry without clear triggers.
E. Inappropriate Affect
Mismatch between emotions and the situation.
Seen in schizophrenia, dementia, and some personality disorders.
Example: Laughing at sad news or crying during happy events.
F. Pseudobulbar Affect (PBA) – Pathological Laughter and Crying
Uncontrollable episodes of crying or laughing that are disproportionate to the situation.
Often due to neurological conditions such as stroke, multiple sclerosis (MS), traumatic brain injury (TBI), and amyotrophic lateral sclerosis (ALS).
Episodes are involuntary and unrelated to the person’s actual emotions.
G. Congruent vs. Incongruent Affect
Mood-Congruent Affect: Emotional response matches the person’s mood (e.g., sadness in depression).
Mood-Incongruent Affect: Emotional response contradicts the person’s mood (e.g., laughing while severely depressed).
Seen in psychotic disorders, schizophrenia, and some types of bipolar disorder.

Depression: Etiology and Psychodynamics
Depression is a multifaceted mental health disorder that significantly impairs emotional regulation, cognitive processing, and physical well-being. It is not merely sadness but a persistent mood disorder that affects millions globally. Understanding its etiology (causes) and psychodynamics is essential for accurate diagnosis, effective treatment, and prevention.
1. Etiology of Depression (Causes and Risk Factors)
Depression arises from a complex interaction of genetic, neurochemical, psychological, and environmental factors. The specific combination of these factors varies among individuals, leading to different types and severity of depressive episodes.
A. Biological Factors
1. Genetic Predisposition (Hereditary Factors)
Depression runs in families, indicating a strong genetic component.
Twin studies show that genetic factors account for 40-50% of the risk for Major Depressive Disorder (MDD).
First-degree relatives of a depressed individual are 2-3 times more likely to develop depression.
Specific genes linked to depression include:
Serotonin Transporter Gene (5-HTTLPR): Affects serotonin levels and emotional regulation.
Brain-Derived Neurotrophic Factor (BDNF): Influences neuroplasticity and resilience to stress.
Dopamine Receptor Gene (DRD4): Plays a role in reward processing and motivation.
Depression is often associated with deficiencies in key neurotransmitters, which regulate mood, motivation, and cognition:
Serotonin (5-HT): Regulates mood, appetite, and sleep; low levels contribute to sadness and anxiety.
Dopamine (DA): Governs motivation and pleasure; deficiency leads to anhedonia (loss of pleasure).
Norepinephrine (NE): Involved in energy and alertness; low levels cause fatigue and lack of concentration.
Although the monoamine hypothesis has guided antidepressant development, recent research suggests that neurotransmitter dysregulation alone is insufficient to explain depression, leading to newer models incorporating neuroplasticity, inflammation, and gut microbiota.
5. Inflammatory & Immune System Dysregulation (Cytokine Hypothesis)
Chronic inflammation has been linked to increased levels of pro-inflammatory cytokines (IL-6, TNF-alpha, C-reactive protein), which contribute to depressive symptoms.
Some cases of treatment-resistant depression respond better to anti-inflammatory treatments rather than traditional antidepressants.
B. Psychological Factors
1. Freud’s Psychoanalytic Theory
Depression is caused by unconscious conflicts, unresolved childhood trauma, and repressed emotions.
Loss, rejection, or inadequate parental care may lead to self-directed anger and guilt, manifesting as depression.
2. Cognitive Theory (Aaron Beck’s Model)
Depression arises from negative thinking patterns and cognitive distortions, known as the Cognitive Triad:
Negative view of self: “I am worthless.”
Negative view of the world: “Everything is unfair.”
Negative view of the future: “Nothing will ever get better.”
Common cognitive distortions in depression include:
Overgeneralization: “I always fail at everything.”
Catastrophizing: “One mistake means my life is ruined.”
Personalization: “It’s my fault that everything is going wrong.”
3. Learned Helplessness Theory (Martin Seligman)
Repeated exposure to uncontrollable negative events (abuse, neglect, failure) leads to a belief that one is powerless to change circumstances, resulting in passivity, hopelessness, and depression.
4. Personality Traits & Depression
Certain personality traits increase vulnerability to depression:
Neuroticism: Higher emotional reactivity to stress.
Perfectionism: Unrealistic self-expectations and self-criticism.
Avoidant Personality: Fear of rejection and difficulty expressing emotions.
C. Social and Environmental Factors
1. Adverse Childhood Experiences (ACE) & Trauma
Emotional neglect, physical/sexual abuse, parental conflict, and unstable childhood environments significantly increase the risk of depression in adulthood.
Early attachment disruptions (inconsistent or neglectful caregiving) lead to difficulty in emotion regulation and interpersonal relationships.
2. Chronic Stress & Life Events
Depression is frequently triggered by stressful life events, including:
Loss of a loved one (bereavement depression).
Divorce or relationship conflicts.
Financial crises and unemployment.
Chronic illness or disability.
3. Social Isolation & Lack of Support
Individuals lacking meaningful relationships, community engagement, or family support have a higher risk of depression.
4. Socioeconomic & Cultural Factors
Economic inequality, discrimination, and lack of access to healthcare contribute to higher depression rates in marginalized populations.
5. Substance Abuse & Depression
Chronic alcohol, nicotine, or drug use disrupts neurotransmitter balance, worsening depressive symptoms.
Alcohol-dependent individuals have a 60% increased risk of developing major depression.
2. Psychodynamics of Depression
Psychodynamic theories provide insight into how unconscious conflicts, personality structures, and early relationships contribute to depression.
A. Freud’s Psychoanalytic Model
Depression results from internalized anger and unresolved grief.
Individuals who experience early loss or rejection may unconsciously blame themselves, leading to self-hatred and depressive symptoms.
B. Object Relations Theory (Melanie Klein & Otto Kernberg)
Poor childhood attachment experiences lead to feelings of emptiness, low self-esteem, and difficulty forming healthy relationships, predisposing individuals to depression.
C. Self-Psychology (Heinz Kohut)
Depression arises from unstable self-esteem, where individuals depend on external validation.
Criticism or failure may lead to self-devaluation and deep emotional distress.
D. Adler’s Inferiority Complex
Persistent feelings of personal failure, self-doubt, and inadequacy contribute to depression.
E. Bowlby’s Attachment Theory
Insecure attachment styles (avoidant or anxious attachment) in childhood increase the risk of developing depression in adulthood.

Diagnosis of Depression
Introduction
Depression is diagnosed using a combination of clinical history, physical examination, psychiatric assessment, and standardized diagnostic criteria. The diagnosis requires persistent symptoms affecting mood, cognition, and physical health for a specific duration. A thorough evaluation helps differentiate depression from medical conditions, medication side effects, and other psychiatric disorders.
1. Diagnostic Criteria for Depression (DSM-5)

At least five (5) of the following symptoms persist for at least two weeks.
At least one of the symptoms must be either:
Depressed mood most of the day, nearly every day.
Loss of interest or pleasure (anhedonia) in almost all activities.
DSM-5 Criteria for Major Depressive Disorder (MDD)
D. Montgomery-Asberg Depression Rating Scale (MADRS)
Evaluates suicidal ideation, anhedonia, and sadness in clinical trials.

Depression Treatment: Antidepressant Drugs, Their Types, Mode of Action, and Nursing Responsibilities
Introduction
Depression is treated through a combination of medications, psychotherapy, and lifestyle modifications. Antidepressant drugs play a crucial role in regulating neurotransmitters and improving mood symptoms. The choice of an antidepressant depends on the severity of depression, patient response, side effects, and comorbid conditions.
1. Types of Antidepressant Drugs
Antidepressants are classified based on their mechanism of action on neurotransmitters like serotonin, norepinephrine, and dopamine.
A. Selective Serotonin Reuptake Inhibitors (SSRIs)
Common Drugs:
Fluoxetine (Prozac)
Sertraline (Zoloft)
Paroxetine (Paxil)
Citalopram (Celexa)
Escitalopram (Lexapro)
Mode of Action:
Blocks the reuptake of serotonin (5-HT) in the synaptic cleft, increasing serotonin levels in the brain.
Helps improve mood, reduce anxiety, and enhance emotional regulation.
Indications:
Major Depressive Disorder (MDD)
Generalized Anxiety Disorder (GAD)
Panic Disorder
Obsessive-Compulsive Disorder (OCD)
Post-Traumatic Stress Disorder (PTSD)
Common Side Effects:
Nausea, headache, dizziness
Sexual dysfunction (decreased libido, anorgasmia)
Insomnia or drowsiness
Increased risk of suicidal thoughts (especially in adolescents)
Nursing Responsibilities:
Monitor for increased suicidal ideation, especially in the first 2-4 weeks.
Educate patients about delayed onset (2-6 weeks) for full effects.
Advise against sudden discontinuation to prevent withdrawal symptoms (flu-like symptoms, dizziness, mood swings).
Monitor for serotonin syndrome (agitation, sweating, tremors, hyperthermia).
B. Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)
Common Drugs:
Venlafaxine (Effexor)
Duloxetine (Cymbalta)
Desvenlafaxine (Pristiq)
Mode of Action:
Inhibits the reuptake of serotonin (5-HT) and norepinephrine (NE), increasing their levels in the brain.
Helps improve energy levels and relieve chronic pain associated with depression.
Indications:
Major Depressive Disorder (MDD)
Generalized Anxiety Disorder (GAD)
Fibromyalgia
Chronic pain syndromes
Common Side Effects:
Hypertension (especially with venlafaxine)
Increased heart rate
Nausea, dizziness, dry mouth
Sweating, sexual dysfunction
Nursing Responsibilities:
Monitor blood pressure regularly (risk of hypertension).
Assess for suicidal ideation, especially in the early weeks.
Educate patients about withdrawal symptoms (taper off slowly).
Monitor liver function tests with duloxetine (risk of hepatotoxicity).
C. Tricyclic Antidepressants (TCAs)
Common Drugs:
Amitriptyline (Elavil)
Imipramine (Tofranil)
Nortriptyline (Pamelor)
Clomipramine (Anafranil)
Mode of Action:
Blocks the reuptake of serotonin (5-HT) and norepinephrine (NE), increasing their availability in the brain.
Also blocks histamine, acetylcholine, and alpha-adrenergic receptors, leading to more side effects.
Mania is a mental state characterized by elevated mood, increased energy, impulsivity, and decreased need for sleep. It is a core feature of bipolar disorder but can also occur in other medical or psychiatric conditions. Understanding the etiology (causes) and psychodynamics of mania helps in its diagnosis and management.
1. Etiology of Mania (Causes and Risk Factors)
Mania arises from a complex interaction of biological, genetic, psychological, and environmental factors. These factors influence brain function, neurotransmitter levels, and emotional regulation.
A. Biological Factors
1. Genetic Predisposition (Hereditary Factors)
Mania has a strong genetic component.
First-degree relatives of individuals with bipolar disorder have a 10-fold increased risk.
Twin studies show that genetic factors contribute 70-80% of the risk for bipolar disorder.
Specific genes associated with mania include:
CACNA1C gene (calcium channel dysfunction).
ANK3 gene (neuronal activity regulation).
2. Neurotransmitter Imbalance
Excessive dopamine (DA) and norepinephrine (NE) levels are associated with mania.
Reduced serotonin (5-HT) activity may contribute to impulsivity and mood instability.
Increased glutamate (excitatory neurotransmitter) leads to hyperactivity and restlessness.
3. Hormonal and HPA Axis Dysregulation
Dysfunction in the hypothalamic-pituitary-adrenal (HPA) axis leads to increased cortisol levels, contributing to mood instability.
Thyroid abnormalities (hyperthyroidism) can trigger manic episodes.
4. Structural and Functional Brain Changes
Hyperactivity in the amygdala (responsible for emotions).
Reduced activity in the prefrontal cortex, leading to poor impulse control.
Increased connectivity in the reward pathway, causing excessive pleasure-seeking behavior.
B. Psychological Factors
1. Freud’s Psychoanalytic Theory
Mania represents a defense mechanism against depression.
Individuals unconsciously suppress negative emotions and overcompensate with excessive energy and confidence.
2. Cognitive and Behavioral Theories
Cognitive Distortions:
Individuals with mania overestimate their abilities and engage in grandiosity.
Individuals with high impulsivity, sensation-seeking tendencies, and low frustration tolerance are more prone to mania.
Borderline personality traits may increase risk.
C. Environmental and Social Factors
1. Stressful Life Events (Triggers)
Major life changes (e.g., job loss, relationship conflicts, trauma) can trigger mania.
Childhood abuse or neglect may increase vulnerability to bipolar disorder.
2. Sleep Deprivation
Lack of sleep can induce or worsen manic episodes.
Disruptions in circadian rhythms are common in manic individuals.
3. Substance Abuse (Drug-Induced Mania)
Stimulants (cocaine, methamphetamine) and hallucinogens (LSD, ecstasy) can trigger manic symptoms.
Excessive caffeine or steroid use can also worsen manic behavior.
4. Medication-Induced Mania
Certain antidepressants (SSRIs, TCAs, SNRIs) can trigger manic episodes in bipolar patients.
Steroids (prednisone), levodopa (for Parkinson’s), and stimulants (ADHD medications) may induce mania.
2. Psychodynamics of Mania
Psychodynamic theories provide insights into how unconscious conflicts, personality structures, and early-life experiences contribute to manic behavior.
A. Freud’s Psychoanalytic Model
Mania is considered a defense mechanism against underlying depression or guilt.
The superego (moral self) is weakened, allowing the id (instinctual drives) to dominate, leading to impulsivity and euphoria.
B. Object Relations Theory (Melanie Klein & Otto Kernberg)
Poor early relationships and attachment issues create an unstable self-image.
Manic episodes serve as a way to escape feelings of emptiness and worthlessness.
C. Carl Jung’s Theory
Mania represents an exaggerated, uncontrolled expression of the “persona” (social mask).
Individuals experience extreme disconnection from their true self, leading to impulsive behaviors.
D. Adler’s Inferiority Complex
Manic behavior compensates for deep-seated feelings of inadequacy.
Individuals seek grandiosity and dominance to mask underlying insecurity.
E. Bipolar as a Defense Against Loss (Manic-Defense Hypothesis)
Mania emerges as a reaction to grief or perceived loss.
The person avoids confronting painful emotions by engaging in excessive activity.

Diagnosis of Mania
Mania is diagnosed using clinical criteria, patient history, psychiatric evaluation, and diagnostic scales. It is a key feature of Bipolar Disorder Type I, but can also occur in substance use disorders, medical conditions, or schizoaffective disorder. Proper diagnosis is essential to differentiate mania from hypomania, schizophrenia, and other mood disorders.
1. Diagnostic Criteria for Mania (DSM-5)
According to the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), mania is diagnosed if:
The patient has experienced a distinct period of abnormally elevated, expansive, or irritable mood and increased energy for at least one week (or any duration if hospitalization is needed).
The episode must include at least three (3) of the following symptoms (or four if the mood is irritable instead of euphoric).
DSM-5 Criteria for Mania
Inflated self-esteem or grandiosity (unrealistic sense of superiority, delusions of greatness).
Decreased need for sleep (feeling rested after only a few hours).
More talkative than usual or pressured speech (rapid, excessive talking).
Flight of ideas or racing thoughts (jumping between topics quickly).
Increased goal-directed activity or psychomotor agitation (restlessness, hyperactivity).
Engaging in risky behaviors (impulsive spending, reckless driving, hypersexuality).
Easily distracted (poor concentration, jumping from task to task).
Additional DSM-5 Criteria:
The symptoms cause significant impairment in work, social, or daily activities.
The episode is not due to substance use or a medical condition.
The episode is not better explained by schizophrenia or schizoaffective disorder.
Note: If a patient has similar but milder symptoms lasting at least 4 days without severe impairment, it is classified as Hypomania (Bipolar II Disorder).
2. ICD-11 Criteria for Mania
The International Classification of Diseases, 11th Edition (ICD-11) defines mania as:
A persistent and severe elevation of mood or irritability lasting at least 1 week.
Increased energy, hyperactivity, and reduced need for sleep.
Overconfidence, grandiosity, or risky behavior.
ICD-11 classifies mania into two types:
Mania without psychotic symptoms – Increased energy and activity, but no delusions or hallucinations.
Mania with psychotic symptoms – Includes delusions (grandiosity, paranoia) or hallucinations.
3. Differential Diagnosis (Conditions That Mimic Mania)
Several medical and psychiatric conditions can resemble mania, requiring careful evaluation.

Bipolar Mood Disorder
Bipolar Mood Disorder: Etiology and Psychodynamics
Introduction
Bipolar Mood Disorder is a chronic psychiatric illness characterized by episodes of mania, hypomania, depression, and mixed states. It significantly impacts mood, energy, cognition, and behavior, often leading to functional impairment and social distress. The disorder has a complex etiology involving genetic, neurobiological, environmental, and psychological factors.
1. Etiology of Bipolar Mood Disorder
The exact cause of Bipolar Disorder is multifactorial, involving genetic, neurochemical, structural, environmental, and psychological factors.
A. Genetic Factors
Strong hereditary component with a high familial prevalence.
First-degree relatives of bipolar patients have a 7-10 times higher risk of developing the disorder.
Polygenic inheritance (multiple genes contribute) rather than a single genetic mutation.
Dysregulation of neurotransmitters plays a crucial role:
Increased dopamine → Associated with mania (hyperactivity, impulsivity).
Decreased serotonin and norepinephrine → Linked to depressive episodes.
GABA dysfunction → Impairs mood regulation.
Glutamate hyperactivity → Can lead to neurotoxicity and excitability.
Mood stabilizers (e.g., Lithium, Valproate) target these imbalances.
C. Neuroanatomical and Structural Abnormalities
Reduced gray matter volume in the prefrontal cortex (affecting decision-making and impulse control).
Enlarged amygdala and hippocampus dysfunction (linked to emotional instability).
Ventricular enlargement seen in MRI studies, indicating structural brain changes.
Dysfunction in the limbic system (emotion regulation) and the prefrontal-limbic network.
D. Hormonal and Endocrine Dysregulation
Hypothalamic-Pituitary-Adrenal (HPA) Axis Dysfunction leads to increased cortisol levels, contributing to stress-induced manic or depressive episodes.
Thyroid dysfunction (hyperthyroidism may trigger mania, hypothyroidism may induce depression).
Inflammatory markers (C-reactive protein, cytokines) are found elevated in bipolar patients, suggesting an immune system role.
E. Environmental and Psychosocial Triggers
Stressful life events (trauma, loss, financial issues) can precipitate episodes.
Substance use (alcohol, stimulants, cannabis) can trigger or worsen mood instability.
Circadian rhythm disturbances (sleep deprivation can trigger manic episodes).
Childhood adversity and abuse increase vulnerability.
2. Psychodynamics of Bipolar Mood Disorder
The psychodynamic perspective of bipolar disorder explores unconscious conflicts, personality structure, and early life experiences in the development of mood instability.
A. Freud’s Psychoanalytic Theory
Mania as a defense mechanism against depression → The manic phase serves as a denial of underlying depression to avoid painful emotions.
Unresolved childhood conflicts and trauma → Emotional dysregulation arises due to early life stressors or loss.
Superego dysfunction → In mania, the superego (self-critical voice) is weakened, leading to grandiosity and disinhibition.
B. Object Relations Theory
Early disruptions in attachment (inconsistent caregiving) can cause mood instability.
Mania serves as a compensatory mechanism for feelings of worthlessness.
Fear of abandonment → Manic episodes may arise from deep-seated fears of rejection and loss.
C. Cognitive-Behavioral Perspectives
Cognitive distortions (negative thought patterns) play a role in bipolar disorder:
Manic phase: Overconfidence, unrealistic goal-setting, and impulsivity.
Depressive phase: Negative self-perception, hopelessness, and self-blame.
Dysfunctional emotional regulation results from faulty coping mechanisms.
CBT (Cognitive Behavioral Therapy) aims to modify these thought distortions.
D. Psychosocial Model
Stress-Diathesis Model: Individuals with a genetic predisposition may develop bipolar disorder when exposed to environmental stressors.
Interpersonal and Social Rhythm Theory (IPSRT): Irregular daily routines and sleep disturbances trigger mood episodes.
Geriatric Considerations and Special Population Considerations for Mood Disorders
Introduction
Mood disorders, including depression, bipolar disorder, and dysthymia, can present differently in special populations, such as older adults (geriatric population), pregnant women, and individuals with chronic illnesses or intellectual disabilities. Proper recognition and treatment are essential for improving quality of life and preventing complications.
1. Geriatric Considerations for Mood Disorders
Mood disorders in older adults may be underdiagnosed due to atypical presentation and overlap with cognitive or physical illnesses.
A. Unique Features of Mood Disorders in Older Adults
Depression may present as apathy, fatigue, or cognitive decline rather than sadness.
Somatic (physical) symptoms such as pain, gastrointestinal issues, and weight loss are common.
Higher risk of suicide due to loneliness, bereavement, and chronic illnesses.
Cognitive impairment (pseudodementia) can mimic dementia but improves with antidepressant treatment.
Increased sensitivity to medication side effects due to slower metabolism and polypharmacy.
B. Risk Factors for Mood Disorders in Older Adults
Follow-up, Home Care, and Rehabilitation in Mood Disorders
Introduction
Mood disorders, including major depressive disorder (MDD), bipolar disorder, and dysthymia, require ongoing management to prevent relapse and ensure functional recovery. Follow-up care, home-based interventions, and rehabilitation programs support individuals in maintaining treatment adherence, improving coping skills, and reintegrating into society.
1. Follow-up Care in Mood Disorders
Objectives of Follow-up Care
Monitor symptom improvement and detect early relapse signs.
Ensure adherence to medications and psychotherapy.
Assess and manage medication side effects.
Provide emotional support and motivation to continue therapy.

Lifestyle Modifications: Encouraging sleep hygiene, balanced diet, and physical activity.
Social Support Assessment: Evaluating family support, work adjustments, and community involvement.
Crisis Prevention: Identifying and managing stressors that may trigger mood episodes.
Frequency of Follow-ups
Acute Phase (First 3 months): Weekly or bi-weekly check-ups.
Maintenance Phase (3-12 months): Monthly visits.
Long-Term Management (>1 year): Every 3-6 months.
2. Home Care for Mood Disorders
Home-Based Nursing Care
Supervising medication adherence to prevent missed doses and ensure proper administration.
Monitoring mental status for signs of mood instability, withdrawal, or agitation.
Providing crisis intervention for suicidal thoughts, aggression, or severe emotional distress.
Educating caregivers on managing mood fluctuations and providing emotional support.

Coordinate with community resources and mental health organizations for long-term care.
4. Preventing Relapse and Ensuring Long-Term Stability
Recognizing Early Warning Signs
Depression Relapse Signs: Increased fatigue, loss of interest, appetite changes, and suicidal thoughts.
Mania Relapse Signs: Reduced sleep need, racing thoughts, impulsivity, and excessive confidence.
Strategies for Relapse Prevention
Medication Adherence: Educate patients on the necessity of continued treatment.
Stress Management: Teach effective coping mechanisms to handle life stressors.
Regular Therapy Participation: Encourage ongoing counseling and psychotherapy.
Avoiding Triggers: Identify and manage individual triggers such as substance use or sleep deprivation.
