Ear Canal Stimulation Can Help Manage Parkinson’s Symptoms

ear
Gentle, controlled stimulation of the ear canal can help reduce symptoms of Parkinson's disease, a new study led by the University of Kent has shown. The randomized, controlled study showed that twice-daily stimulation for two months was associated with a significant reduction in both motor and non-motor features of Parkinson's disease. Participants reported greater movement …

ALS Trajectory May Be Affected By Gut Microbes

microbiology lab
Intestinal microbes, collectively termed the gut microbiome, may affect the course of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, researchers at the Weizmann Institute of Science have shown in mice. Progression of an ALS-like disease was slowed after the mice received certain strains of gut microbes or substances known to be secreted …

Fingerprint Of Multiple Sclerosis Immune Cells Identified

fingerprint
Researchers report identifying the “fingerprint” of the immune cells that characterize multiple sclerosis. The discovery could lead to new ways to monitor and treat the disease. “We identified a specific population of white blood cells augmented in the peripheral blood of MS patients that have two properties characteristic of MS: They can move from the …

Alzheimer’s Gene APOE May Effect Cognition Before Adulthood

ACMSD
A gene associated with Alzheimer’s disease may have an impact on cognitive health much sooner than previously realized, new research suggests. The APOE gene creates a protein, apolipoprotein E, which packages cholesterol and other fats to transport them through the bloodstream. There are three versions, or alleles, of APOE. One of those is the APOE4 …

Antioxidant Precursor Molecule Could Improve Parkinson’s

alcoholism dopamine
N-acetylcysteine (NAC) is a naturally occurring molecule that replenishes one of the body's antioxidants and now shows potential benefit as part of a standard course of treatment for patients with Parkinson's disease, according to a new study. The study found improvements in dopamine levels, the primary neurotransmitter that is specifically decreased in Parkinson's disease, as …

Gut Microbes Protect Against Neurologic Damage From Viral Infections

bacteria
Trillions of bacteria, fungi and viruses live inside us, forming what is known as our microbiota. Far from causing problems, these microbes benefit our health in many ways. Most of our microbiota lives in our gut, yet there is increasing evidence that it can influence how our central nervous system works. Gut microbes produce compounds …

Alzheimer’s Family History Associated With Impaired Learning

linked
Adults having a close relative with Alzheimer's disease do more poorly in online paired-learning tasks than adults without such a family history, new research has found. Additionally, this impairment appears to be worsened by having diabetes or a genetic variation in the apolipoprotein E (APOE) gene linked to the disease. The findings may help identify …

Tau Proteins Spread More Easily In The Aging Brain

P301Ltau misfolding
Certain molecules involved in Alzheimer's disease called tau-proteins spread more easily in the aging brain, new research in mice from German investigators suggests. The study was carried out in collaboration with researchers in the US at Harvard Medical School and Massachusetts General Hospital. Alzheimer’s disease usually begins with memory decline and later affects other cognitive …
