Calcium directs blood flow in the brain by controlling blood vessel contractions, a new study reveals.
A new study sheds light on the role dehydration can play in pain perception and cerebral blood flow.
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.
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.
Researchers report on the neurological benefits of talking a walk.
Cerebral blood flow is reduced in the Broca's area of people who stutter, researchers report. Additionally, the more severely a person stutters, the less blood flows to this area of the brain.
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%.
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.
Inherent randomness in the flow rate of red blood cells through capillaries could be a cause of oxygen fluctuations in the brain.
Researchers use two-photon imaging and optogenetics to isolate and study brain capillaries in animal models.
According to a new study, poor kidney function is linked to stroke and dementia as a result of decreased blood flow to the brain.
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.
