Study Notes
Neurotransmitters and Their Functions
- Neurotransmitters are natural chemicals that transmit messages between brain cells.
- Imbalances in neurotransmitters can impact mental health and mood.
Diagnostic Procedures
- PET (positron-emission tomography) scans measure blood flow and activity in the brain, assisting in identifying issues like schizophrenia.
- CT (computed tomography) scans are used to differentiate conditions such as Alzheimer's disease from multiple infarcts.
Neuroanatomy and Disorders
- The hypothalamus regulates functions like fluid intake and hunger; dysfunction can lead to excessive fluid intake and calorie consumption.
- Disorganized thinking in schizophrenia is often associated with frontal lobe dysfunction.
Circadian Rhythms in Depression
- Assessment of circadian rhythm disturbances in patients with major depressive disorder includes understanding their patterns of daily activity.
Effects of Medications
- Medications enhancing GABA (gamma-aminobutyric acid) typically result in reduced anxiety.
- Drugs inhibiting the breakdown of acetylcholine are expected in patients experiencing memory difficulties.
Side Effects of Mental Health Medications
- Anticholinergic drugs may lead to inhibited functions of the parasympathetic nervous system, causing symptoms like dry mouth.
- Dopamine-blocking medication can lead to restlessness and an urge for constant movement.
Treatment for Anxiety and Depression
- Benzodiazepines are often prescribed for acute anxiety, while SSRIs (selective serotonin reuptake inhibitors) like sertraline are common for treating major depressive disorder.
Weight Gain and Mental Health Medications
- Certain medications that block H1 receptors may contribute to weight gain in patients with schizophrenia.
Vital Signs and Stress Responses
- Exposure to stressors, such as encountering a poisonous snake, can lead to increased blood pressure and heart rate as part of the body's fight-or-flight response.
Medication Groupings and Indications
- Valproate is categorized with carbamazepine and lamotrigine, which are used for seizure disorders and bipolar disorder.
Patient Education and Compliance
- Important to inform patients taking clozapine about the need to report signs of infection, like sore throat and fever, due to potential agranulocytosis.
Nonjudgmental Patient Communication
- Asking open-ended questions about herbal remedies allows for better understanding without being judgmental.
Memory and Brain Structures
- The hippocampus, amygdala, and temporal lobe are crucial structures involved in memory function.
Functional Magnetic Resonance Imaging (fMRI)
- fMRI tests can reveal physical causes for psychiatric symptoms and provide insights for appropriate treatment planning.
Monitoring for Adverse Effects
- Special care is necessary for patients on second-generation antipsychotics, especially those with co-morbid conditions like diabetes and hyperlipidemia, which could exacerbate side effects.
