Brain Cells 'Burn Out' in Parkinson's Disease

Brain cells in Parkinson's disease exhaust themselves and die prematurely, burning out like an "overheating motor", an early study suggests.

Canadian researchers say the findings might help explain why only small parts of the brain are affected in the disease.

Dementia Drug Data Set to be Revealed

Eagerly awaited data on the most promising drug in treating Alzheimer's disease is set to be unveiled later.

Patients and scientists hope it could become the first medication to slow the pace of brain decline.

Sniffing Could Provide Autism Test

The way children sniff different aromas could form the basis of a test for autism, suggest researchers in Israel.

People spend longer inhaling the delightful aroma of a bouquet of roses than the foul stench of rotting fish.

White Matter Damage in Brain and Early Alzheimer's

Study finds widespread changes using specialized MRI

Hormone Therapy Doesn't Help Memory: Study

Researchers did see mood improvement in women on oral treatment

Women taking menopausal hormone therapy to relieve symptoms such as hot flashes often hope it will also help their menopause-related memory and thinking problems, but a new study reports it won't.

Could a Diet Help Shield You From Alzheimer's?

Scientists say the MIND eating plan significantly reduces risk of the brain disorder

Dementia 'Halted in Mice Brains'

Tweaking the brain's immune system with a drug has prevented mice developing dementia, a study shows.

The team at Duke University, in the US, showed immune cells which start attacking nutrients in the brain may be a trigger for the disease.

Being Overweight 'Reduces Dementia Risk'

Being overweight cuts the risk of dementia, according to the largest and most precise investigation into the relationship.

The researchers admit they were surprised by the findings, which run contrary to current health advice.

Green Tea Linked to Lower Risk for Dementia

A green tea habit is tied to a lower risk for dementia and mild declines in thinking and memory among older people, a new Japanese study shows. The piping-hot perk doesn't seem to apply to black tea or coffee, though, the researchers say.

Researchers Pinpoint Possible Alzheimer's Culprit

Postmortem analysis of almost 1,400 brains implicates tau, not amyloid, buildup driving memory loss

Abnormal tau protein collecting in the brain may be the main cause of Alzheimer's disease, a new study claims.
