Alzheimer's disease
noun
condition where a patient suffers from presenile dementia in middle age, caused when areas of the brain atrophy, making the ventricles expand
COMMENT: no cause has been identified for the disease, although it is more prevalent in certain families than in others. It appears to be linked to a mutant gene on chromosome 21 (which is itself linked to Down's syndrome). It is thought that there may be a connection between Alzheimer's disease and absorption by the body of aluminium

Alzheimer's disease
Alzheimer's disease (AD), also known simply as Alzheimer's, is a neurodegenerative disease that, in its most common form, is found in people over age 65. Approximately 24 million people worldwide have dementia of which the majority (~60%) is due to Alzheimer's.
Clinical signs of Alzheimer's disease are characterized by progressive cognitive deterioration, together with declining activities of daily living and by neuropsychiatric symptoms or behavioral changes. It is the most common type of dementia. Plaques which contain misfolded peptides called amyloid beta (Aβ) are formed in the brain many years before the clinical signs of Alzheimer's are observed. Together, these plaques and neurofibrillary tangles form the pathological hallmarks of the disease. These features can only be discovered at autopsy and help to confirm the clinical diagnosis. Medications can help reduce the symptoms of the disease, but they cannot change the course of the underlying pathology.
