Hyperbaric oxygen therapy improved cerebral blood flow by up to 23%, alleviating vascular dysfunction and amyloid burden in elderly patients. The treatment also improved memory by 16.5%.
REM sleep significantly increases the flow of red blood cells through the brain's capillaries.
Calcium directs blood flow in the brain by controlling blood vessel contractions, a new study reveals.
Inherent randomness in the flow rate of red blood cells through capillaries could be a cause of oxygen fluctuations in the brain.
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.
Researchers use two-photon imaging and optogenetics to isolate and study brain capillaries in animal models.
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.
Exercise is associated with improved brain function and a decrease in cerebral blood flow in older people with mild cognitive impairment, a new study reports.
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.
According to a new study, children and young adults with chronic kidney disease have changes in cerebral blood flow that could increase the risk of cognitive impairment.
