Depression

Depression, also known as major depressive disorder (MDD), is a common but serious mood disorder that affects how a person feels, thinks, and handles daily activities. It involves persistent feelings of sadness and loss of interest that can interfere significantly with everyday life.

​

Key Characteristics

​

Symptoms:

• Persistent sad, anxious, or "empty" mood

• Loss of interest or pleasure in activities once enjoyed

• Fatigue or decreased energy

• Difficulty concentrating, remembering, or making decisions

• Changes in appetite or weight

• Sleep disturbances, including insomnia or oversleeping

• Feelings of worthlessness, guilt, or hopelessness

• Thoughts of death or suicide in more severe cases

 

Causes:

• Genetics: A family history of depression or other mood disorders increases risk.

• Brain Chemistry: Imbalances in neurotransmitters such as serotonin, norepinephrine, and dopamine.

• Environmental Factors: Chronic stress, trauma, or significant life changes can trigger or worsen symptoms.

• Medical and Hormonal Factors: Certain medical conditions, medications, and hormonal changes can contribute to depressive episodes.

 

Diagnosis:

• Typically based on a clinical evaluation, including patient history and assessment of symptom duration and severity using standardized criteria.

• Lab tests or physical exams may be used to rule out underlying medical conditions that can mimic depressive symptoms.

 

Treatment:

• Psychotherapy: Cognitive behavioral therapy (CBT), interpersonal therapy, and other evidence-based approaches to address thought patterns and coping skills.

• Medications: Antidepressants such as SSRIs, SNRIs, and other classes may be prescribed based on individual needs.

• Emerging Treatments: For treatment-resistant cases, options such as transcranial magnetic stimulation (TMS) or ketamine-based therapies may be considered.

• Lifestyle and Home Remedies: Regular physical activity, consistent sleep patterns, stress management, and social support can complement clinical treatment.

 

Complications:

• Impact on Relationships: Depression can strain personal and professional relationships.

• Physical Health: Increased risk of chronic conditions such as heart disease and weakened immune function.

• Substance Use: Higher risk of turning to alcohol or drugs as a coping mechanism.

• Risk to Safety: Severe depression can increase the risk of self-harm or suicidal thoughts, requiring immediate clinical attention. If you or someone you know is struggling, help is available 24/7 through the 988 Suicide & Crisis Lifeline (call or text 988).
