Study suggests role of inflammation in brain disease is complicated. Scientists drilling down to the molecular roots of Alzheimer’s disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person’s risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system’s ability to protect the brain from amyloid beta, a key protein associated with Alzheimer’s.
Findings of a new and comprehensive study from FSU College of Medicine Associate Professor Antonio Terracciano and colleagues, published today in the journal JAMA Psychiatry, has found no evidence to support the idea that personality changes begin before the clinical onset of mild cognitive impairment (MCI) or dementia.
Intermittent electrical stimulation of key brain area that degenerates in Alzheimer’s improves memory
Intermittent electrical stimulation of an area deep inside the brain that degenerates in Alzheimer’s appears to improve working memory, scientists report.
Women genetically predisposed to Alzheimer’s are more susceptible than men between ages 65 and 75, researchers discover
Researchers at Lund University have developed a new imaging method that can help doctors detect and track Alzheimer’s disease in people of different ages more effectively.
