How Possible Or Definite Alzheimer's Disease Is Diagnosed
Possible alzheimer's disease
is diagnosed when the patient has lost memory very slowly and laboratory and
urine testing find no other physical reasons to account for the memory loss.
Definite alzheimer's disease is diagnosed reliably only by autopsy. The presence
of significant senile plaques and neurofibrillary tangles in the brain confirms
the clinical diagnosis of alzheimer's disease. Studies have shown that trained
clinicians can diagnose alzheimer's disease with about a 90% accuracy, even
without an autopsy to confirm actual alzheimer's brain changes.
