The characteristic pathological change in the brains of patients with Alzheimer's disease is the neurofibrillary tangle, an accumulation of amyloid proteins. Microscopic infarcts in the white matter of the brain are characteristic of vascular dementia. Demyelination (loss of myelin from the sheaths that surround the axons of nerves) is a characteristic finding in multiple sclerosis, not Alzheimer's. Atrophy of the basal ganglia is found in Parkinson's disease.
