Study Notes
Organic Mental Disorders
- Common symptoms include:
- CCHD (Cerebro Cardiovascular Disease) and dementia, characterized by mainly loss of memory
- Cognitive impairment, specifically delirium, marked by mainly loss of concentration
Alzheimer's Disease
- Risk factors:
- Age is the most important risk factor
- Other risk factors include head injury, hypertension, insulin resistance, and depression
- Protective factors:
- High education levels
- Remaining physically and mentally active till late in life
Clinical Features
- Floccillations (or carphologia):
- Aimless picking behavior, where the patient appears to be picking at their clothes or bed
- Example: A patient may move their hands as if they are sewing, even though they are not actually doing so
- Occupational delirium:
- Patient behaves as if they are still on their job, despite being in the hospital
- Example: A patient may behave as if they are still working at their job, even though they are hospitalized
Neurochemistry of Alzheimer's Disease
- Alzheimer's disease is primarily a disorder of cholinergic neurons.
- Loss of cholinergic neurons is a consistent finding in Alzheimer's disease.
- Apart from acetylcholine, serotonin and norepinephrine are also implicated in some cases of Alzheimer's disease.
Genetics of Alzheimer's Disease
- Alzheimer's disease has shown linkage to chromosomes 1, 14, and 21.
Treatment of Alzheimer's Disease
- Treatment involves management of risk factors.
- Cholinesterase inhibitors are used in the treatment of Alzheimer's disease.
Binswanger's Disease
- Also known as subcortical arteriosclerotic encephalopathy.
- Characterized by multiple small white matter infarctions.
- Can produce symptoms of subcortical dementia.
