Do that for 20 minutes, twice a day, for four weeks. These brief breathing sessions had significant impacts: Volunteers’ heart rate variability increased during each exercise period...
By Neha Mathur Apr 9 2023 Reviewed by Danielle Ellis, B.Sc. In a recent study published in the Journal of the Alzheimer’s Association (AA), researchers examined the effects of a low-carbohydrate-modified Mediterranean ketogenic diet (MMKD) on the gut microbiome and metabolome of patients at risk for Alzheimer’s disease (AD). Study: Effects of a ketogenic and low-fat diet on the...
by Amanda Steffen, Yale University Credit: Unsplash/CC0 Public Domain If you have ever let your mind wander, you have relied on the brain’s default mode network (DMN). Scientifically, the DMN is a connection of brain regions that interact when a person is in a state of wakeful rest. This network is important for using our...
UNIVERSIDAD COMPLUTENSE DE MADRID UCC-UCM, 26 July 2022. In subjects who are cognitively healthy but have a high genetic risk of developing Alzheimer’s, correlations have been demonstrated between the retina and various brain structures which suffer changes as a result of the disease, such as the entorhinal cortex, the lingual gyrus and the hippocampus. This is the...
To understand what causes Alzheimer’s disease and other forms of brain degeneration, scientists may need to look beyond the brain’s computational units, the neurons and synapses, and explore the vast infrastructure that supports them. Scientists have recognized for decades that the brains of people who die from advanced Alzheimer’s disease often exhibit severe damage to the...
by Scott Gilbert, Pennsylvania State University Credit: Unsplash/CC0 Public Domain No effective treatment for Alzheimer’s disease exists, even though more than 5 million Americans have it. But what if there was a way to reduce the risk? Research suggests there may be methods to protect yourself. What is Alzheimer’s disease? “Alzheimer’s is the most common form...
By Nick Lavars May 18, 2021 Scientists have identified a new set of blood-based biomarkers that may help predict Alzheimer’s risk maxxyustas/Depositphotos While the exact causes behind Alzheimer’s are still unknown, research is beginning to demonstrate how biomarkers of the disease might reveal themselves long before symptoms appear, raising the prospect of earlier diagnosis and better treatments...
