Alzheimer's disease (AD) is a neurodegenerative disease that usually starts slowly and progressively worsens. [2] It is the cause of 60–70% of cases of dementia. [2] [15] The most common early symptom is difficulty in remembering recent events. [1]
This is in contrast to Alzheimer's disease pathology, which tends to level off and perhaps decrease in prevalence among persons beyond age 85 years. [1] LATE is often comorbid with (i.e., occurs in the same brain as) other pathologic changes that are also associated with dementia, such as Alzheimer's disease and cerebrovascular disease(s). [4 ...
The onset of the deficits has been between the ages of 40 and 90 years and finally there must be an absence of other diseases capable of producing a dementia syndrome. Possible Alzheimer's disease: There is a dementia syndrome with an atypical onset, presentation or progression; and without a known etiology; but no co-morbid diseases capable of ...
(Reuters) -Alzheimer's disease experts are revamping the way doctors diagnose patients with the progressive brain disorder - the most common type of dementia - by devising a seven-point rating ...
With increasing clinical focus on dementia, there is likewise increasing interest in pharmacology in the development of drugs to halt, or slow the progression of dementia-related illness such as Alzheimer's Disease. Therefore, early and accurate diagnosis of dementia and staging can be essential to proper clinical care.
In addition, an alpha-synuclein fragment, known as the non-Abeta component (NAC), is found in amyloid plaques in Alzheimer's disease. tau: hyperphosphorylated tau protein is the main component of neurofibrillary tangles in Alzheimer's disease; tau fibrils are the main component of Pick bodies found in behavioral variant frontotemporal dementia.
A new study distinguishes between two distinct phases of Alzheimer's disease: an early, 'stealth' one without symptoms, and a second phase that aggressively damages the brain.
The most common type of mixed dementia is Alzheimer's disease and vascular dementia. [87] This particular type of mixed dementia's main onsets are a mixture of old age, high blood pressure, and damage to blood vessels in the brain. [15] Diagnosis of mixed dementia can be difficult, as often only one type will predominate.
