Alzheimers Disease

In patients showing cognitive decline, a new blood test for Alzheimer's is expected to make diagnosis more convenient, accessible and inexpensive than other existing tests.

The lower incidence of dementia seen in adults who received the shingles vaccine is likely not just a correlation, scientists say, based on new results of an observational study.

A man who should have developed early-onset Alzheimer's disease due to a genetic mutation is still symptom-free in his 70s. Scientists are trying to understand why.

A study using lab-made models of the brain suggests that a herpes virus may be a key link between concussions and dementia risk.

In a new study, scientists have identified 14 modifiable risk factors that boost dementia rates, but could be addressed.

A new study begins to unpack an understudied aspect of brain biology and Alzheimer's disease.

Once more, sildenafil, the main active component of the "little blue pill," has been found to be associated with a reduced risk of developing Alzheimer's disease.

A small study suggests that "seeds" of Alzheimer's can be transferred from one person to another via certain medical procedures, leading to the disease later in life.

Knowing that Alzheimer's comes in at least five distinct forms could change the treatment landscape, the scientists behind the new study say.
