Alzheimer's Disease

A new study has somewhat redeemed the tau protein, which up to now has been associated with the development of Alzheimer’s disease. Turns out, the protein has a ‘good guy’ role, helping to protect against harmful free radicals in the brain.

In a medical emergency, quick treatment is critical. But a widely used drug could be repurposed to induce a hibernation-like state, to slow down organ damage and save lives by giving patients more time to reach a hospital.

A drug used to induce labor in pregnant women has been shown to reactivate tiny waste-clearing pumps in the brains of old mice. The finding could hold promise for fighting Alzheimer's and Parkinson's diseases and overall cognitive decline.

Instead of focusing on fighting the plaques linked to Alzheimer's, researchers took a look at boosting electrical oscillations in the brain. The molecule they invented got the job done in mice, offering hope for a new treatment path for humans.

A new report by world-leading experts lists 14 modifiable risk factors associated with 40% of all dementia cases that, if addressed by people across their lifespan, could reduce the likelihood of developing the condition or delay its onset.

Brain parasites are something that most people would naturally want to avoid, but maybe they can be used for good. A new study has found that a common brain parasite could be engineered to deliver drugs past the blood-brain barrier.

One dose of a new treatment, delivered by nasal spray, clears away build-ups of the toxic tau protein associated with Alzheimer’s disease from inside brain cells, improving memory, according to new research. It paves the way for new treatments for the debilitating disease.

An innovative biodegradable paper that sticks to the brain’s surface like a Band-Aid and delivers electrical stimulation wirelessly could revolutionize the treatment of neurological diseases like Parkinson’s and Alzheimer’s, according to a new study.

A study has found that having two APOE4 genes may not just be a risk factor in Alzheimer's disease, but a driver of it. Nearly all carriers' brains showed key disease biomarkers by age 65, suggesting it may instead be a type of inheritable Alzheimer's.

The world’s most powerful MRI machine has scanned its first living human brains. The resulting images give an ultra high resolution glimpse into the brain, to help us better understand the nature of consciousness and treat neurodegenerative diseases.

In the human species, bigger brains suggest better brain health and cognitive function. And since the 1930s, our brains have been growing. Now, a new study shows how this is affecting our risk of developing dementia, particularly Alzheimer's disease.

Researchers have discovered that limiting a certain enzyme can have a dramatic impact in protecting against the effects of Alzheimer's disease. The finding could lead to a new class of drugs that fight the disease.
