  • May be less severe but more enduring than Major Depressive Disorder
• Postpartum Depression affects some women after childbirth
  • Symptoms extend beyond typical "baby blues" and can severely impact mother-child bonding
  • Risk factors include hormonal changes, sleep deprivation, and adjustment to parenthood

• Bipolar Disorder characterized by alternating episodes of mania and depression
  • Manic episodes involve elevated mood, increased energy, and risky behavior

• Cyclothymic Disorder features milder mood swings over an extended period
  • Symptoms don't meet full criteria for manic or depressive episodes
  • Must persist for at least two years in adults, one year in children and adolescents

Neurobiological Basis and Pharmacological Interventions

• Neurotransmitters play a crucial role in mood regulation and mental health

  • Dopamine involved in motivation and pleasure
• Psychopharmacology utilizes medications to address chemical imbalances
  • Selective Serotonin Reuptake Inhibitors (SSRIs) commonly prescribed for depression and anxiety
  • Mood stabilizers (lithium, anticonvulsants) used in treating bipolar disorder
  • Benzodiazepines sometimes prescribed for short-term anxiety relief
• Genetic factors contribute to vulnerability to mood and anxiety disorders
  • Family history often indicates increased risk
  • Epigenetic changes can influence gene expression and mental health outcomes

Psychological Interventions and Holistic Approaches

• Cognitive Behavioral Therapy (CBT) effective for both anxiety and depressive disorders
  • Focuses on identifying and changing negative thought patterns and behaviors
