Cerebral haemodynamics, the study of blood flow within the brain, is central to understanding how the organ meets its extraordinary metabolic demands. Autoregulation refers to the intrinsic ability of ...

Cerebral blood flow (CBF) and oxygen metabolism underpin the fundamental processes that sustain neural function and viability. The delivery of oxygen via the bloodstream is essential for maintaining ...

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 ...

“ATT may be more sensitive to age-related decline than CBF, and therefore useful for early detection and management of cerebrovascular impairment.” “ATT may be more sensitive to age-related decline ...

Over seven million Americans are living with Alzheimer’s disease (AD) and the heartbreaking day-to-day battle with the effects of cognitive decline. According to the Alzheimer’s Association, the brain ...

Cognitive functions, also known as intellectual functions, encompass thinking, understanding, memory, language, computation, and judgment, and are performed in the cerebrum. The prefrontal cortex (PFC ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

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 ...

Blocking calcium channels in brain capillaries may enhance blood flow and alleviate early-stage Alzheimer's damage, new study suggests. Study: Inhibiting Ca 2+ channels in Alzheimer’s disease model ...

Strangulation vs. Choking: A Dangerous Confusion The language we use matters. Choking refers to an airway being blocked internally, while strangulation involves external compression of the neck, ...
