Can the brain heal after lack of oxygen?

A full recovery from severe anoxic or hypoxic brain injury is rare, but many patients with mild anoxic or hypoxic brain injuries are capable of

making a full or partial recovery

. Furthermore, symptoms and effects of the injury are dependent on the area(s) of the brain that was affected by the lack of oxygen.

Is hypoxic brain injury permanent?

Accidents, heart attacks and strokes can deprive the brain of oxygen, leading to cerebral hypoxia. Cerebral hypoxia is a medical emergency.

It can cause permanent brain injury

.

Memory loss can begin from

age 45

, scientists say. As all those of middle age who have ever fumbled for a name to fit a face will believe, the brain begins to lose sharpness of memory and powers of reasoning and understanding not from 60 as previously thought, but from as early as 45, scientists say.
