Alzheimer's Disease

Research looking at records from half a million people has identified 22 associations between viral infections and neurodegenerative disease. Influenza, encephalitis and other infections were linked to increased rates of Parkinson's, Alzheimer's and MS.

New research has found HRT can be linked with better brain health and cognition among women with a genetic risk of developing Alzheimer's. The findings build on research trying to understand why women are more likely to develop Alzheimer's compared to men.

A fascinating study has shed light on how the trillions of microbes in our gut could be affecting our brain health. The research found mice engineered to develop Alzheimer's developed fewer signs of neurodegeneration when raised with no gut bacteria.

As is the case with so many other things, the sooner that Alzheimer's disease is detected, the more that can be done to slow its progress. An experimental implantable lens could help, by changing in appearance at the early stages of the illness.

The FDA has approved a new drug for patients in the early-stages of Alzheimer's disease but growing concerns over its safety and real-world efficacy have led to division amongst researchers, with some suggesting it should not be authorized for wide use.

Could the phenomenon of whale and dolphin strandings be due to Alzheimer's-like cognitive deficits in pod leaders that draw groups into shallow waters? A new study found pathological signs of Alzheimer's disease in brain tissue from stranded dolphins.

A new study is presenting evidence suggesting viral infections in the olfactory system can accelerate the progression of Alzheimer's disease. The research looked at the relationship between markers of infections and neurodegeneration in the hippocampus.

A new study has reported on the first human tests of an experimental therapy using sound and light to treat Alzheimer's disease. The initial results are promising, with the treatment leading to some neurological and cognitive improvements.

A genetic predisposition to ADHD has been linked to an increased risk of cognitive decline and Alzheimer's disease in old age, according to new research. The findings are the first to associate ADHD genetic risk with age-related cognitive impairment.

A first-of-its-kind meta-analysis has found a significant association between the use of hearing aids and a reduced risk of dementia. The findings suggest that using hearing restoration devices could slow the progression of cognitive decline.

Scientists at Yale University have uncovered an overlooked mechanism that may be behind the symptoms of Alzheimer’s disease. The team points the finger at small swellings on axons near plaques that build up in the brain, suggesting new drug targets.

In a new study published in Frontiers in Aging Neuroscience, researchers propose urine tests as a potential way to detect Alzheimer's disease. The study suggests formic acid levels in urine could be a useful early-stage biomarker for the disease.
