Brain changes may help track dementia, even before diagnosis

Even before a dementia diagnosis, people with mild cognitive impairment may have different changes in the brain depending on what type of dementia they have, according to a study published in the September 11, 2019, online ...

Scientists link 'hunger hormone' to memory in Alzheimer's study

Scientists at The University of Texas at Dallas have found evidence suggesting that resistance to the "hunger hormone" ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer's ...

New drug targets early instigator of Alzheimer's disease

Over a hundred years after they were first identified, two ominous signposts of Alzheimer's disease (AD) remain central topics of research—both formed by sticky accumulations of protein in the brain. Amyloid beta solidifies ...

An alternate theory for what causes Alzheimer's disease

Alzheimer's disease, the most common cause of dementia among the elderly, is characterized by plaques and tangles in the brain, with most efforts at finding a cure focused on these abnormal structures. But a University of ...

Tissue model reveals role of blood-brain barrier in Alzheimer's

Beta-amyloid plaques, the protein aggregates that form in the brains of Alzheimer's patients, disrupt many brain functions and can kill neurons. They can also damage the blood-brain barrier—the normally tight border that ...

Direct toxic action of beta-amyloid identified

Hyperactive neurons in specific areas of the brain are believed to be an early perturbation in Alzheimer's disease. For the first time, a team from the Technical University of Munich (TUM) was able to explain the reasons ...
