Study Notes

Major Depressive Disorder (MDD)

Females are diagnosed with MDD twice as often as males
MDD in males is often masked by alcohol and drug abuse
Possible explanations for the higher occurrence of depression in females:
- X-linked depression genes
- Premenstrual syndrome symptoms
- Quality of life differences between genders
- Female masochism (Freud)
- Cognitive style differences:
  - Females tend to dwell on problems
  - Males tend to avoid or escape problems
"Kindling" and depression risk: previous depressive episodes increase the risk of future episodes
Persistent depressive disorder and "double depression":
- There is a depressive episode occurring on top of persistent depressive disorder
- Individuals struggling with "baseline" depression experience a deeper depressive episode
Psychotic features in severe MDD:
- Hallucinations (e.g., hearing voices)
- Delusions (e.g., beliefs of guilt or worthlessness)

Treatment for MDD

Psychotherapy
- Cognitive Behavioral Therapy (CBT): Targets negative thought patterns, and proven effective
- Interpersonal Therapy (IPT): Focuses on relationship issues, supported by evidence
- Behavioral Activation: Increases engaging in positive activities, effective for lifting mood
Natural Remission: Some depressive episodes resolve on their own, suggesting natural cycles and influencing theories of depression's episodic nature
Problems with Psychogenic Theories: Potential for overemphasis on psychological origins, neglecting biological causes and limiting treatment options
Third-wave CBT Variants:
- Acceptance and Commitment Therapy (ACT): Encourages acceptance of thoughts, proven effective
- Mindfulness-Based Cognitive Therapy (MBCT): Uses mindfulness to prevent relapse, supported by evidence
Brain changes in depression:
- Low levels of Brain-Derived Neurotrophic Factor (BDNF)
- Neurotransmitter imbalances
- Neocortical disturbances
- Antidepressants potentially normalize these changes
Types of Antidepressant Medications:
- Classes: SSRIs, SNRIs, MAOIs, tricyclics
- Use: Depression, anxiety, OCD
- Side Effects: Vary by class, include fatigue, nausea, and dry mouth
- Precautions: Careful dosage, side effects may affect treatment adherence
Antidepressant Medication and Suicidality:
- Initial treatment phase may increase suicide risk, requiring close monitoring
- Highest risk is when individuals feel better and don't want to return to their previous state, or finally having the motivation to take their own life
Electroconvulsive Therapy (ECT)
- Nature of treatment: Controlled electrical impulses used to induce seizures
- Effectiveness: High for severe depression, potential side effect of memory loss
Alternative Treatments:
- Transcranial Magnetic Stimulation (TMS): Stimulates brain regions, "Stanford protocol" showing promising results
- Vagus Nerve Stimulation (VNS): Device used to stimulate the vagus nerve
- Ketamine: Rapid relief in severe cases, requires careful supervision
Comparative Effectiveness of Medications vs Psychotherapy:
- Mild to moderate depression: both can be effective
- Severe cases: May benefit more from medication

Other Disorders and Mental Health

Seasonal Affective Disorder (SAD): Depression linked to seasons
Phototherapy: Light therapy for mood improvement, effective in many cases
Other disorders associated with depression: Often treated with antidepressants

Mental Health Professions

Direct Patient Care Roles:
- Psychiatrists (M.D.'s)
- Clinical Psychologists (Ph.D.'s)
- Social Workers (M.S.W.'s / D.S.W.'s)
- Psychiatric Nurses (R.N.'s)
- Marriage & Family Therapists (M.F.T.'s)
- Psych Technicians
- Mental Health Intake Workers, Staff
- Primary Care Practitioner M.D.'s (PCP’s)
- Physician Assistants (P.A.’s)
- Nurse Practitioners (N.P.’s)
Mental Health Research Roles:
- Psychiatrists
- Clinical psychologists
- Neuroscientists
- Endocrinologists
- Psychopharmacologists
- Geneticists
- Epidemiologists
- Clinical trial managers
- Biostatisticians

Potential Contributors to Declining Young People's Mental Health

Social media use: Promotes social comparison, lowering self-esteem, especially in young females
Climate anxiety: Repeated warnings about environmental crises increase stress
Helicopter parenting: Limits resilience by protecting children from failure or disappointment
Education without competition: Reduces preparedness for college and real-world challenges
Pressure to attend college: Family and personal expectations pushing students towards college over alternative paths
Over-pathologizing normal feelings: Everyday emotions like boredom or loneliness being labeled as disorders
Decreased stigma: Social media influencers openly discussing diagnoses, making mental health labels more common

Managed Care

Insurance-based model emphasizing cost-efficient, brief treatments
Critics argue it can limit the quality of mental health care

Research Methods in Psychopathology

Advantages and Disadvantages of Research Methods:
- Clinical Case Studies (Case Histories)
  - Advantages: Detailed, in-depth insights, useful for rare cases
  - Disadvantages: Limited generalizability, potential researcher bias
- Correlational Methods
  - Advantages: Identifies relationships between variables, useful in large populations
  - Disadvantages: Cannot determine causation
- Experimental Methods
  - Advantages: Establishes cause-and-effect relationships
  - Disadvantages: Ethical concerns, limited real-world applicability, cost and time
