Short-Term Memory Loss May Be Best Predictor of Alzheimer's

Symptoms of 'mild cognitive impairment' outperformed other screening tests,

This study reported by HealthDay News on September 5 -- Mild cognitive impairment -- marked by a loss in short-term memory in particular -- may be a stronger predictor of Alzheimer's disease than other screening tests commonly used to diagnose Alzheimer's. 


People with MCI can generally recall events in the more distant past in detail, however, and are usually able to reason, solve problems and communicate well with others in spite of relatively minor memory loss. In addition, not all cases of MCI progress to Alzheimer's disease.

Mild cognitive impairment is usually marked by difficulties with short-term memory, such as losing your train of thought repeatedly or having trouble remembering what you did yesterday. You may begin to demonstrate uncharacteristically poor judgment or have trouble finding your way around familiar places. Some people may also develop depression or anxiety, or show signs of unusual irritation, aggression or apathy.

The study appears in the September issue of the Archives of General Psychiatry.
