Alzheimer's disease

Alzheimer's disease

Alzheimer's disease is the most common dementing disorder. The pathophysiology remains unknown, although several features are associated with its presence. These include genetic factors, excessive NMDA stimulation, a reduction in choline acetyltransferase activity, the presence of amyloid-beta plaques, and neurofibrillary tangles and neuroinflammation.

 

These changes seem to start in the nucleus basalis of Meynert and progress through the cortex. This leads to a progressive, irreversible, neurodegenerative illness with cognitive loss, behavioural changes and a loss in independence being the major clinical symptoms. Treatment of Alzheimer's disease.
