    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.
