**MAIN CONTENT**
### Definitions and Terminology
* **Psychiatry**: A branch of medicine that focuses on the diagnosis, treatment, and prevention of mental health disorders.
* **Mental Health Disorder**: A condition that affects an individual's emotional, behavioral, or cognitive functioning.
* Key Terms:
+ Psychosis: A condition characterized by a disconnection from reality, often involving hallucinations and delusions.
+ Depression: A mood disorder marked by persistent feelings of sadness, hopelessness, and loss of interest in activities.
### Pathophysiology/ Mechanisms
* **Neurotransmitters**: Chemical messengers that transmit signals between neurons, playing a crucial role in psychiatric disorders (e.g., serotonin, dopamine).
* **Brain Regions**: Areas of the brain involved in emotional regulation, such as the amygdala and prefrontal cortex.
* Key Concepts:
+ The biopsychosocial model: A framework that considers the interplay between biological, psychological, and social factors in psychiatric disorders.
### Clinical Presentations
* **Major Psychiatric Disorders**: Conditions characterized by significant impairment in functioning, such as schizophrenia, bipolar disorder, and major depressive disorder.
* **Mood Disorders**: Conditions marked by changes in mood, including depression and bipolar disorder.
* Key Features:
+ Schizophrenia: Hallucinations, delusions, disorganized thinking, and negative symptoms (e.g., apathy).
+ Major Depressive Disorder: Persistent feelings of sadness, hopelessness, loss of interest in activities.
### Diagnostic Approach
* **DSM-5**: The most widely used diagnostic manual for psychiatric disorders.
* **Clinical Interviews**: A crucial tool for gathering information about a patient's symptoms and history.
* Key Strategies:
+ Focus on the patient's subjective experience (e.g., "How are you feeling today?").
+ Use open-ended questions to gather detailed information.
### Treatment Strategies
* **Pharmacotherapy**: Medications used to treat psychiatric disorders, such as antidepressants and antipsychotics.
* **Psychotherapy**: Non-pharmacological interventions aimed at promoting mental health and well-being (e.g., cognitive-behavioral therapy).
* Key Principles:
+ Patient-centered care: Tailoring treatment to the individual's needs and preferences.
+ Collaborative approach: Working with patients, families, and other healthcare professionals.
### Complications and Prognosis
* **Suicide Risk**: A significant concern in psychiatric disorders, particularly in individuals with a history of suicidal ideation or behavior.
* **Comorbidities**: Common co-occurring medical conditions, such as diabetes and cardiovascular disease.
* Key Factors:
+ Patient motivation: The individual's willingness to engage in treatment and adhere to recommendations.
+ Treatment adherence: Regular attendance at appointments and compliance with medication regimens.
**CLINICAL CASES (2-3 brief cases)**
1. A 35-year-old female presents with symptoms of depression, including persistent feelings of sadness and loss of interest in activities. She reports a history of trauma and substance abuse.
* Discussion points: How would you approach this patient's diagnosis and treatment?
+ Key takeaways: Consider the patient's social determinants of health (e.g., socioeconomic status, access to healthcare) when developing a treatment plan.
2. A 50-year-old male presents with symptoms of schizophrenia, including hallucinations and disorganized thinking.
* Discussion points: How would you differentiate between schizophrenia and other psychiatric conditions?
+ Key takeaways: Use a systematic approach to gathering information about the patient's symptoms and history.
3. A 20-year-old female presents with symptoms of bipolar disorder, including manic episodes and depressive episodes.
* Discussion points: How would you manage this patient's mood stabilization and treatment plan?
+ Key takeaways: Regularly monitor the patient's mood and adjust their treatment plan as needed.
