Depression: Types, Symptoms, Causes and Management

Depression is a common mental health disorder characterised by persistent low mood, loss of interest or pleasure, and changes in emotional, cognitive, behavioural, and physical functioning. It is more than temporary sadness and can affect a person's academic performance, professional life, relationships, and overall well-being. It may occur at any stage of life, including adolescence, adulthood, and old age.

Types of Depression

Major types and related conditions include Major Depressive Disorder (MDD), Persistent Depressive Disorder (Dysthymia), Bipolar Depression, Seasonal Affective Disorder (SAD), Postpartum Depression, Premenstrual Dysphoric Disorder (PMDD), Psychotic Depression, Atypical Depression, Situational Depression (Adjustment Disorder with Depressed Mood), and Depression with Melancholic Features. These conditions differ in their symptoms, duration, and clinical characteristics.

Major Symptoms of Depression

Symptoms can be classified into four categories:

• Emotional: Persistent sadness, hopelessness, irritability, frequent crying, and loss of interest.

• Cognitive: Poor concentration, indecisiveness, negative thinking, excessive guilt, feelings of worthlessness, and recurrent thoughts of death or self-harm.

• Behavioural: Reduced motivation, social withdrawal, decreased productivity, and neglect of daily responsibilities.

• Physical: Sleep disturbances, appetite and weight changes, fatigue, low energy, and unexplained physical complaints.

Causes and Risk Factors

Depression generally results from a combination of biological, psychological, and social factors. Biological factors include genetic susceptibility, neurochemical changes, hormonal influences, sleep disturbances, and certain medical conditions. Psychological factors include low self-esteem, negative thinking patterns, poor coping skills, and persistent stress. Social factors include family conflicts, relationship problems, bereavement, social isolation, financial difficulties, and academic or occupational stress.

Depression, Stress and Anxiety

Stress is a response to challenging situations, whereas depression is a mental health condition. Prolonged stress may increase the risk of depression. Depression mainly involves low mood and loss of interest, while anxiety is characterised by excessive fear, worry, restlessness, and tension. Both conditions may occur together.

Management of Depression

Management depends on the severity and individual needs of the patient. Major approaches include:

1. Psychological treatment: Cognitive Behavioural Therapy (CBT), interpersonal therapy, behavioural approaches, and supportive psychotherapy.

2. Pharmacological treatment: Antidepressants such as SSRIs, SNRIs, tricyclic antidepressants (TCAs), and monoamine oxidase inhibitors (MAOIs).

3. Lifestyle modifications: Regular physical activity, a balanced diet, adequate sleep, social support, stress management, and maintaining a healthy daily routine.

4. Specialised treatment: Severe cases may require brain-stimulation therapies under specialist supervision.

Role of the Pharmacist

Pharmacists play an important role in depression management by promoting rational medicine use, explaining dosage and administration, encouraging medication adherence, identifying adverse drug reactions and potential interactions, and providing patient counselling. They should maintain confidentiality, adopt a non-judgmental approach, and refer patients to qualified mental-health professionals whenever necessary.
