Unit 1591: Neurobiology of Mental Disorders

1. Introduction to Neurobiology of Mental Disorders

• Overview of neurobiology: definition and scope
• Relationship between neurobiology and mental disorders
• Basic principles of neurobiology relevant to mental health
• Importance of neurobiological understanding in diagnosis and treatment

2. Neurotransmitters and Mental Disorders

• Definition and function of neurotransmitters
• Key neurotransmitters involved in mental disorders:
  • Serotonin
  • Dopamine
  • Norepinephrine
  • GABA
  • Glutamate
• Role of neurotransmitter imbalances in depression, anxiety, schizophrenia, and others
• Neurotransmitter pathways and receptor mechanisms

3. Brain Structures and Mental Health

• Key brain structures involved:
  • Amygdala: role in emotion and fear processing
  • Hippocampus: memory and stress regulation
  • Prefrontal cortex: executive function and decision making
• Structural and functional changes observed in mental disorders
• Impact of brain circuitry disruptions on symptomatology

4. Genetics and Mental Disorders

• Genetic predisposition and heritability
• Study of genetic markers and polymorphisms linked to mental illnesses
• Examples: Bipolar disorder, autism spectrum disorders
• Gene-environment interactions
• Epigenetic influences on mental health

5. Neuroplasticity and Mental Health

• Definition and mechanisms of neuroplasticity
• Role in brain adaptation, learning, and recovery
• Neuroplasticity in response to therapy and interventions
• Implications for treatment strategies

6. Neuroinflammation and Psychiatric Disorders

• Concept of neuroinflammation and immune system dysregulation
• Evidence linking neuroinflammation with schizophrenia, bipolar disorder, and other conditions
• Pathophysiological mechanisms
• Potential therapeutic targets

7. Neuroimaging Techniques in Mental Health Research

• Overview of neuroimaging modalities:
  • Functional Magnetic Resonance Imaging (fMRI)
  • Positron Emission Tomography (PET)
  • Electroencephalography (EEG)
• Applications in studying brain activity and structure
• Insights gained from neuroimaging studies in mental disorders
• Limitations and ethical considerations

8. Pharmacology of Psychotropic Medications

• Classes of psychotropic drugs:
  • Antidepressants (SSRIs, SNRIs, MAOIs, TCAs)
  • Antipsychotics (typical and atypical)
  • Mood stabilizers
• Mechanisms of action
• Therapeutic uses and side effects
• Challenges in pharmacological treatment

9. Stress, Trauma, and Neurobiology

• Impact of acute and chronic stress on brain structure and function
• Neurobiological mechanisms underlying trauma-related disorders
• PTSD and major depressive disorder: neurobiological perspectives
• Role of the hypothalamic-pituitary-adrenal (HPA) axis

10. Emerging Trends in Neurobiology and Mental Health

• Advances in neurogenetics and personalized medicine
• Novel neuroimaging techniques and biomarkers
• Innovations in neuromodulation and brain stimulation therapies
• Integrative approaches combining neurobiology with psychosocial treatments
• Future directions in research and clinical practice
