Sildenafil, an FDA-approved drug to treat erectile dysfunction (Viagra) and pulmonary hypertension, appears to be a promising candidate to prevent and treat Alzheimer's disease.
Cataract surgery was associated with a 30% reduction in dementia risk for older adults, a new study reports.
Walking exercise on a treadmill improves cognitive abilities, including learning and memory, and preserves hippocampal volume in people with relapse-remitting multiple sclerosis.
Older people who experience elevated heart rates are at increased risk for developing dementia, researchers report.
Microglia, a key immune cell in the brain, appears to mediate the relationship between the gut microbiome and amyloid-beta deposits in male mouse models of Alzheimer's disease.
A drug currently being tested in cancer clinical trials appears to prevent dysfunction in an immune cell signaling pathway associated with Alzheimer's disease. Blocking the pathway could prevent Alzheimer's from developing and slow the progression of symptoms for those who already have the disease.
A neuroimaging study reveals significant structural differences in the brain of fetuses exposed to alcohol. Researchers found alcohol exposed fetuses had increased volume in the corpus callosum and decreased volume in the periventricular zone of the brain.
A unique subset of group 3 innate lymphoid cells spurs T cells to attack myelinated nerve fibers in mouse models of multiple sclerosis.
Amateur boxers, specifically those who boxed during their youth, are twice as likely to develop Alzheimer's disease than those who didn't.
Researchers have developed a new, non-invasive method to remove dysfunctional brain circuitry and surgically treat neurological conditions. The technique, called PING, uses focused ultrasound combined with microbubbles to penetrate the blood-brain barrier and deliver neurotoxins targeted at the problematic brain area.
