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.
Alzheimer's Disease Neuroimaging Initiative (ADNI) is a multisite study that aims to improve clinical trials for the prevention and treatment of Alzheimer's disease (AD). [1] This cooperative study combines expertise and funding from the private and public sector to study subjects with AD, as well as those who may develop AD and controls with ...
Studies using MRI and PET have documented reductions in the size of specific brain regions in people with Alzheimer's disease as they progressed from mild cognitive impairment to Alzheimer's disease, and in comparison with similar images from healthy older adults.
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.
Alzheimer’s disease affects millions of Americans and is one of the top 10 causes of death in the U.S. ... the doctors performed MRI scans of the abdomen and thighs. The PET scans were used to ...
In vivo magnetic resonance spectroscopy (MRS) is a specialized technique associated with magnetic resonance imaging (MRI). [1] [2]Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non-invasive, ionizing-radiation-free analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's ...
Dementia is a devastating condition that impacts up to 10 percent of older adults. And while there's no cure, getting diagnosed early can help patients get on a treatment plan and families prepare ...
As stated above, a behavioural change may occur before the appearance of any atrophy in the brain in the course of the disease. Because of that, image scanning such as MRI can be insensitive to the early degeneration and it is difficult to detect early-stage bvFTD. [citation needed]
