Cognitive impairment is common in patients with end-stage renal disease treated with hemodialysis. Despite this well-recognized link, the etiology of cognitive impairment in hemodialysis patients has ...

Optical monitoring of cerebral blood flow is a potentially life-saving technology in clinical emergencies, and a number of spectroscopic techniques have been applied to the task. Near-IR spectroscopy ...

Intensive blood pressure control to a target of less than 120 mm Hg was not associated with a reduction of cerebral perfusion compared with a standard target of less than 140 mm Hg in a substudy of ...

Enhancing prefrontal cortex (PFC) cognitive functions requires identifying suitable exercises that increase cerebral blood flow. A recent study using functional near-infrared spectroscopy found that ...

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation ...

This soft and stretchy ultrasound patch can be worn on the temple to provide continuous monitoring of blood flow in the brain. During use, the patch is connected through cables to a power source and ...

Dementia has long been framed as a slow, irreversible loss of neurons, but a new line of research is shifting attention to the blood vessels that feed the brain. Scientists are now testing whether ...
