organic brain syndrome (acute reversible dementia)

Organic brain syndrome is the deterioration of the mental or intellectual ability of a person. Generally, organic brain syndrome is preceded by physical problems such as cerebral arteriosclerotic disease, degeneration of nerve tissue, head injuries, reduced blood flow to the brain, a minor stroke, fever, intoxication of alcohol and drugs, nutritional deficiency, metabolic disturbances, pneumonia, myocardial infarction, diabetes, syphilis, renal failure, or fluid and electrolyte imbalances. Organic brain syndrome is usually reversible, which differentiates it from Alzheimer's disease. Symptoms or organic brain syndrome include impaired judgment, loss of memory, emotional instability, deterioration of the thought process, disorientation, and incoherence. Symptoms may come and go, which is probably related to the amount of blood flow to the brain at any given time. Treatment involves determining the cause of the condition. Many times the condition is reversible when the underlying medical problem is discovered and treated.
