Major Depressive Disorder (MDD)

Major Depressive Disorder (MDD) Overview

  • Definition: Major Depressive Disorder (MDD), also referred to as clinical depression.

  • Symptoms: Clients may exhibit the following characteristics:

    • Mood: Severely depressed mood, described as feeling like "blah"; likened to Eeyore from Winnie the Pooh.

    • Energy: Low energy, feeling slow and heavy.

Causes of MDD

  • Neurotransmitter Imbalance: Thought to be caused by low levels of neurotransmitters, specifically:

    • Serotonin: Affects mood and happiness.

    • Dopamine: Influences pleasure and reward.

    • Norepinephrine: Involved in arousal and alertness.

  • Unknown Causes: While the exact cause of depression remains unknown, several risk factors contribute to its development.

  • Risk Factors:

    • Stressful Life Events: Trauma, death of a loved one, job loss can lead to increased stress.

    • Chronic Illness: Debilitating conditions such as Parkinson’s disease.

    • Genetic Factors: Family history of depression increases the likelihood.

    • Gender: Females are more commonly affected than males.

    • Substance Abuse: Particularly involving alcohol or drugs.

Symptoms and Diagnosis of MDD

  • Diagnostic Criteria: To diagnose MDD, five or more symptoms must be present consistently for at least two weeks. Major symptoms include:

    1. Depressed Mood: Feelings of hopelessness and emptiness.

    2. Anhedonia: Significant loss of joy and interest in life.

    3. Weight Changes: Typically presents as anorexia, but can also be weight gain; more common is loss of appetite with rapid weight loss.

    4. Psychomotor Retardation: Slow speech, decreased movement; clients may take longer to respond, reminiscent of Eeyore’s slow response times.

    5. Sleep Disturbances: Insomnia or hypersomnia (excessive sleeping).

    6. Fatigue (Anergia): Heavy fatigue, inability to perform basic activities such as eating or grooming.

    7. Feelings of Worthlessness or Guilt: Commonly experienced.

    8. Difficulty Concentrating: Challenges with focus and attention.

    9. Suicidal Thoughts: Recurrent thoughts of self-harm.

  • Special Considerations for Adolescents: Adolescents aged 10-19 may exhibit:

    • Angry or aggressive outbursts.

    • Vandalism and suspension of class attendance.

    • Sudden changes in weight.

    • Excessive daytime sleepiness.

    • Withdrawal from previously enjoyed activities.

Types of Depression

  • Dysthymia: A long-term persistent depression characterized by mild symptoms lasting two years or more.

  • Seasonal Affective Disorder: Occurs in winter due to lack of sunlight; treated with light therapy.

  • Pre and Postpartum Depression: Occurs during pregnancy or within four weeks post-delivery, often related to hormonal changes.

Treatment Phases for MDD

  • Phase 1: Acute Phase

    • Duration: 6-8 weeks.

    • Goals: Remission of symptoms, restore function; high suicide risk.

    • Treatment: Antidepressant medications, psychotherapy, Electroconvulsive Therapy (ECT).

  • Phase 2: Continuation Phase

    • Focus on increased functionality and preventing relapse.

  • Phase 3: Maintenance Phase

    • Duration: 6-12 months.

    • Aim: Prevent recurrence; foster return to normal functioning.

Nursing Care Considerations

  • Suicide Risk Assessment:

    • Key signs include a sudden increase in energy, which may suggest a heightened risk for suicide, especially after starting antidepressants.

    • Clients may begin giving away possessions or make statements indicating hopelessness (e.g., "I can't go on").

  • Direct Assessment Questions: Ask clear, blunt questions about intent and plans for self-harm, such as:

    • "Have you had any thoughts of hurting yourself?"

    • "Do you have a plan to kill yourself?"

    • "Do you want to die?"

  • Intervention Priorities:

    1. Continuous One-on-One Observation: Essential for clients at risk; 72-hour hold.

    2. Room Assignment: Semi-private rooms near the nurses' station decrease isolation.

    3. Removal of Harmful Objects: Dangers such as sharp items or ties must be removed.

    4. Supervision During Meals: Critical to monitor dietary intake.

    5. Behavioral Improvements: Intent that includes plans involving family and friends suggests reduced suicide risk.

Encouragement and Support for Clients

  • Assist clients in participating in their treatment plans and encourage engagement in activities.

  • Help with Activities of Daily Living (ADLs) due to fatigue and motivation challenges.

  • Reviewing Client Improvement: Look for increased interest in life and communication of personal goals that align with recovery.

Nutritional Considerations

  • Monitor for rapid weight loss or gain; weight loss is more commonly tested:

    • Meal Provision Strategies:

    1. Offer small, frequent meals.

    2. Emphasize high-calorie foods and fluids.

    3. Stay with clients during meals to ensure they finish.

    4. Conduct weekly weight checks to track progress.

Therapeutic Communication

  • Therapeutic communication is defined as a face-to-face process of interpersonal interaction which aims to enhance the client’s understanding of their feelings and experiences. This can help pave the way for more effective treatment and support during sessions.
