A new study reveals a potential link between REM sleep behavior disorder and an increased risk of developing Parkinson's disease. Researchers say the sleep disorder alters cerebral blood flow, leading to a lack of oxygen in brain tissue. This, in the long term, may increase Parkinson's risk.
Obesity has been linked to severely restricted blood flow in the brain. Reduced blood flow in the brain, or cerebral hypoperfusion, can be an early indicator of vascular dementia and Alzheimer's disease.
Capillary constriction caused by amyloid beta restricts cerebral blood flow in mouse models of Alzheimer's disease. Inhibiting the capillary constriction may potentially reduce some of the neurodegenerative features of Alzheimer's.
A new study reports the Ketogenic diet can help to improve cognition. The study reports the Ketogenic diet can help improve balance in the gut microbiome, lower blood glucose levels and increase the processes that help to clear amyloid beta from the brain.
Researchers report applying ultrasound to the whole brain improves cognitive dysfunction in mouse models of dementia. A clinical trial is currently underway to test the effectiveness in humans with the neurodegenerative disease.
