Radiology, neurology. 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.
Steroid dementia syndrome. Steroid dementia syndrome describes the signs and symptoms of hippocampal and prefrontal cortical dysfunction, such as deficits in memory, attention, and executive function, induced by glucocorticoids. [1] Dementia-like symptoms have been found in some individuals who have been exposed to glucocorticoid medication ...
Subtle changes in brain activity in the presence of both amyloid-beta and tau proteins may point to Alzheimer's disease, long before symptoms appear, a new study indicates.
Depression of Alzheimer disease.

The higher a participant’s score, the lower their risk of brain disease. Up to one-third or more of people older than 60 experience late-life depression, the risk of which can be influenced by ...
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 ...
When compared with people who took DPP-4 inhibitors, those who took SGLT-2 inhibitors had a 35 percent lower chance of developing dementia. Not only that, they had a 52 percent lower risk of ...
