The brain may clean out Alzheimer’s plaques during sleep

Losing Sleep
Alzheimer’s disease disrupts sleep. And disrupted sleep itself might encourage Alzheimer’s by allowing build-up of amyloid-beta, or A-beta, which is thought to lead to the death of neurons. This cycle of sleep deprivation can also affect levels of the hormone melatonin, which helps the body to sleep, and can interfere with metabolism, a disruption that is also a risk factor for Alzheimer’s.


One Bad Night
Using PET scans to measure amyloid-beta markers, researchers compared levels of A-beta in the brains of 20 healthy volunteers after one restful night and after one night of sleep deprivation. Levels of the plaque-forming A-beta rose in most people tested.

There is mounting evidence that herpes leads to Alzheimers Disease

More than 30 million people worldwide suffer from Alzheimer’s disease – the most common form of dementia. Unfortunately, there is no cure, only drugs to ease the symptoms. However, my own research suggests a way to treat the disease. I have found the strongest evidence yet that the herpes virus is a cause of Alzheimer’s, suggesting that effective and safe antiviral drugs might be able to treat the disease. We might even be able to vaccinate our children against it. The virus implicated in Alzheimer’s disease , herpes simplex virus type 1 (HSV1), is better known for causing cold sores. It infects most people in infancy and then remains dormant in the peripheral nervous system (the part of the nervous system that isn’t the brain and the spinal cord). Occasionally, if a person is stressed, the virus becomes activated and, in some people, it causes cold sores. The virus can become active in the brain, perhaps repeatedly, and this probably causes cumulative damage. The likel

# Alzheimer’s Disease is a progressive disease that destroys memory and other important mental functions. # Brain cell connections and the cells themselves degenerate and die, eventually destroying memory and other important # mental functions. Memory loss and confusion are the main symptoms. No cure exists, but #medication and management strategies may temporarily improve symptoms. Although there’s no # cure , there are things you can do to help prevent, delay, or slow down Alzheimer’s disease and # dementia . Exercising regularly Getting a good night’s sleep Being MIND-ful about your diet Stress management Socializing Learning new things Lowering high blood pressure and cholesterol Losing weight Brushing and flossing Playing brain games Taking nutritional supplements Protecting your noggin Keeping your gut microbiome healthy Taking medications All of the above Know more at: https://alzheimers-dementia.pulsusconferenc
