What is Depression?

Depression is a serious mental health condition that disrupts an individual’s emotional and physical well-being. Commonly known as clinical depression, it encompasses conditions like Major Depressive Disorder (MDD) and Treatment-Resistant Depression (TRD). It is not just feeling “low” but involves persistent sadness, lack of energy, and a diminished ability to function in daily life. Depression can range from mild to severe and requires tailored treatment.

Major Depressive Disorder (MDD)

MDD is one of the most prevalent forms of depression, characterized by severe symptoms that last for at least two weeks and significantly affect daily functioning. These symptoms include a loss of interest in activities, emotional numbness, and a deep sense of despair. MDD often requires professional intervention through therapy, medication, or a combination of both.

Treatment-Resistant Depression (TRD)

In some cases, depression persists despite multiple treatments, leading to a diagnosis of Treatment-Resistant Depression. TRD requires advanced therapies such as Electroconvulsive Therapy (ECT), Transcranial Magnetic Stimulation (TMS), or Spravato (Esketamine). It underscores the complexity of depression and highlights the need for ongoing innovation in treatment methods.

Symptoms of Depression

1. Emotional Symptoms:

• Persistent feelings of sadness, hopelessness, or emptiness.

• Loss of interest or pleasure in hobbies and activities.

• Irritability or frustration, even over small matters.

2. Cognitive Symptoms:

• Difficulty concentrating, remembering, or making decisions.

• Persistent negative thoughts or feelings of worthlessness.

• Thoughts of death or suicide.

3. Physical Symptoms:

• Fatigue or decreased energy.

• Changes in appetite or weight (either loss or gain).

• Sleep disturbances, such as insomnia or oversleeping.

• Unexplained aches, pains, or digestive problems.

Types of Depression

1. Major Depressive Disorder (MDD): Severe symptoms that interfere with daily life and persist for at least two weeks.

2. Treatment-Resistant Depression (TRD): A condition that occurs when at least two different antidepressants don't improve symptoms of depression.

3. Persistent Depressive Disorder (Dysthymia): A chronic form of depression lasting two years or more, with milder symptoms.

4. Postpartum Depression: A severe form of depression that occurs after childbirth.

5. Seasonal Affective Disorder (SAD): Depression that follows a seasonal pattern, typically worsening in winter.

6. Bipolar Disorder-Related Depression: Depressive episodes that alternate with periods of mania or hypomania.

Causes and Risk Factors

1. Biological Factors: Imbalances in brain chemicals like serotonin, dopamine, and norepinephrine.

2. Genetics: A family history of depression increases susceptibility.

3. Life Events: Stressful situations, trauma, or loss can trigger depressive episodes.

4. Chronic Illnesses: Conditions like diabetes, heart disease, or chronic pain may contribute to depression.

5. Substance Abuse: Drug or alcohol dependence can worsen or trigger depression.

Diagnosis

1. Clinical Interview: A detailed discussion with a mental health professional about symptoms, medical history, and life circumstances.

2. Standardized Assessments: Questionnaires like the Patient Health Questionnaire-9 (PHQ-9) help gauge symptom severity.

3. Rule Out Other Causes: Medical tests to ensure symptoms are not caused by conditions like thyroid issues or medication side effects.

Treatment Options

1. Psychotherapy:

• Cognitive Behavioural Therapy (CBT): Helps identify and change negative thought patterns.

• Interpersonal Therapy (IPT): Focuses on improving relationships and communication.

2. Medications:

• Antidepressants: Selective serotonin reuptake inhibitors (SSRIs) like fluoxetine or sertraline are commonly prescribed.

• Atypical Antidepressants: Medications such as bupropion target different brain pathways.

3. Lifestyle Changes:

• Regular exercise, which boosts endorphin levels.

• Maintaining a healthy diet and consistent sleep schedule.

• Stress-reduction techniques like meditation or yoga.

4. Advanced Therapies for TRD & MDD:

• Transcranial Magnetic Stimulation (TMS): A non-invasive therapy using magnetic pulses to stimulate underactive areas of the brain involved in mood regulation. TMS is painless, with minimal side effects, and is effective for those unresponsive to medication.

• Spravato (Esketamine): A nasal spray derived from ketamine, administered under supervision. It acts rapidly by targeting glutamate, providing relief within hours or days for severe cases or those with suicidal ideation.

Living with Depression

1. Build a Support System: Share your feelings with trusted family members or friends.

2. Stick to a Routine: Establishing a daily structure can provide a sense of stability.

3. Avoid Self-Isolation: Engage in social activities or join support groups.

4. Recognize Triggers: Monitor patterns and seek help early when symptoms worsen.

What to Do If You Suspect Depression

1. Seek Professional Help: Consult a therapist, psychiatrist, or primary care physician for an evaluation.

2. Educate Yourself: Learn about the disorder to reduce stigma and empower effective management.

3. Emergency Help: If thoughts of self-harm or suicide occur, reach out to the crisis line, or seek immediate assistance.
