Study Notes
Basics of Psychiatry
- Frontal lobe is essential for control and regulation of emotions.
Components of MSE (Mental Status Examination)
-
Mood and Affect:
- Mood: Sustained emotional state; long-term.
- Affect: External expression of internal emotions; often short-lived.
-
Perception:
- Disturbances include:
- Illusions: Misinterpretation of real stimuli (e.g., mistaking a rope for a snake).
-
Hallucinations: Perception without any actual stimulus (e.g., seeing nonexistent snakes).
- Characteristics of hallucinations include:
- Occur without sensory stimulus.
- Vivid as real perceptions.
- Experienced externally, not under conscious control.
- Characteristics of hallucinations include:
- Pseudohallucinations: Similar to hallucinations but perceived internally (e.g., voices originating from one’s mind).
- Disturbances include:
Specific Types of Disturbed Mood
- Euphoria: Excessive happiness often seen in mania.
- Dysphoria: Irritability or restlessness, notably in mania.
- Labile Mood: Rapid and unpredictable changes in mood without clear cause.
- Affective Flattening: Diminished emotional response, common in schizophrenia.
- Anhedonia: Inability to feel pleasure in previously enjoyable activities, often seen in depression.
Neuroanatomy of Emotions
- Generation of Emotions: Primarily involves the limbic system, including the hippocampus, amygdala, hypothalamus, and cingulate gyrus.
Cognitive Disturbances
- Loosening of Association: Disconnection between thought components.
-
Delusion Types:
- Delusion of Negation: Denial of existence of oneself or the world.
- Delusion of Enormity: Belief that one’s actions will lead to catastrophic results.
- Delusion of Misidentification: Distrust in one’s own identity, suggestive of serious mental illness.
Hallucinations and Treatment
-
Specific Hallucinations:
- Hypnagogic: Occur when falling asleep, often associated with narcolepsy.
- Hypnopompic: Occur upon waking up, also linked to narcolepsy.
- Reflex Hallucinations: Stimulation in one sensory modality leads to hallucinations in another.
Suicide and Violence Risk in Schizophrenia
- Approximately 10% of patients with schizophrenia may die by suicide, with 5-6% indicated in DSM-5.
- Recommended treatment duration is at least one year for first episodes and 5 years for multiple episodes.
Antipsychotic Medications
-
Typical Antipsychotics (First Generation):
- Mechanism: D2 receptor antagonism.
- Primarily effective against positive symptoms.
- Associated with more extrapyramidal symptoms and hyperprolactinemia.
-
Atypical Antipsychotics (Second Generation):
- Mechanism: D2 and 5HT2 receptor antagonism.
- Effective against both positive and negative symptoms.
- Fewer extrapyramidal symptoms but more metabolic side effects.
Common Side Effects of Antipsychotics
- Acute Akathisia: Characterized by inner restlessness, pacing, and inability to sit still; treated with propranolol or benzodiazepines.
Separation Anxiety Disorder
- More common in children; characterized by excessive fear of separation from attachment figures.
- Symptoms include reluctance to be away from home or attachment figures and physical symptoms like headaches or stomachaches.
- Treatment typically incorporates SSRIs and cognitive-behavioral therapy (CBT).
