Even mild dehydration can diminish cognitive and physical performance, so it's important to maintain adequate hydration and electrolyte levels for brain health.

Stem cells in the adult brain can promote recovery after injuries like stroke by secreting growth factors that enhance native neurogenesis and modulate the immune system.

A stroke is like a heart attack of the brain, caused by disruption of blood flow either from a blocked vessel or a hemorrhage, leading to tissue death and neurological dysfunction.

Transient Ischemic Attacks (TIAs) are reversible strokes that result in temporary loss of function, such as paralysis or speech difficulties, but resolve quickly.

Improving blood flow to the brain through regular exercise enhances cognitive function and reduces inflammation, which is linked to cognitive decline.

Alcohol lowers core body temperature, which can lead to hypothermia if one enters cold water while inebriated, making it extremely dangerous.

Physical activity and rehabilitation are crucial for stroke recovery; engaging in forced activity can stimulate recovery in the affected brain circuits.

Cold exposure can stimulate shivering, which helps in burning fat and converting white fat to brown fat, aiding in fat oxidation.

Both light and moderate alcohol consumption can reduce brain thickness, indicating negative effects on brain health, and there's a dose-dependent increase in the shrinkage of gray matter and white matter tracts in the brain as a function of alcohol consumption.
