Amyloid-related imaging abnormalities (ARIA) are abnormal differences seen in magnetic resonance imaging of the brain in patients with Alzheimer's disease. ARIA is associated with anti-amyloid drugs, particularly human monoclonal antibodies such as aducanumab. [1] There are two types of ARIA: ARIA-E and ARIA-H.
Frontotemporal dementia is an early onset disorder that mostly occurs between the ages of 45 and 65, [13] but can begin earlier, and in 20–25% of cases onset is later. [11] [14] Men and women appear to be equally affected. [15]
The diagnosis of Alzheimer's disease typically requires a microscopic analysis of plaques and tangles in brain tissue, usually at autopsy. [40] However, Aβ plaques (along with cerebral Aβ-amyloid angiopathy ) can be detected in the brains of living subjects by preparing radiolabeled agents that bind selectively to Aβ deposits in the brain ...
People with dementia with Lewy bodies share many of the same symptoms of Alzheimer’s disease and Parkinson’s disease, including cognitive issues such as memory loss, problem-solving, and ...
Not only that, they had a 52 percent lower risk of vascular dementia, and a 39 percent lower risk of Alzheimer’s dementia. People who took SGLT-2 inhibitors for longer periods of time seemed to ...
With dementia or Alzheimer’s, the changes are more drastic—and much more aggressive. “They may not actually be able to take care of themselves and go about their daily life,” McKay says.
CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...
