Stress: Good, Bad and Ugly

Posted by: michael  :  Category: Factors affecting Brain Health

Good:
Stress protects the body in times of threat

Bad:
Stress causes the brain to release powerful stress hormones (adrenaline, norepinephrine and cortisol) and if that mechanism is frequently activated the presence of these hormones can damage the cells in the brain and in particular cause shrinkage in the hippocampus – an area of the brain important in memory and learning.

Ugly:
Prolonged stress plays havoc with the functioning of the brain and the body systems it controls. Stress can reduce the naturally occurring replacement of brain cells and weaken the connections between cells – both factors are critical in brain cell communications and memory.
