DETECTING DETERIORATION: SLEEP DISORDERS AND EARLY-ONSET DEMENTIA

Sleep disorders

Prolonged sleep deprivation also takes its toll on brain function. Sleep apnoea (see ‘Not Tonight Darling, I’m Snoring’ on p. 30) and disorders such as periodic leg movement and insomnia may cause such deprivation.

As they age, many men experience a disintegration in their diurnal rhythms. Their internal clock becomes less efficient and they spend half the night awake and half the day asleep. With this, their ability to concentrate deteriorates.

Early-onset dementia

Alzheimer’s and other dementias can start in the 40s and remain undiagnosed for long periods. They become evident when the man’s behaviour changes. Some men become socially inept and disinhibited. A disinhibited man will make poor decisions, will be impulsive and will not take all factors into account. Other men become withdrawn. They stop interacting and seem emotionally flat. They lose their drive and are not sufficiently organised to get to make a decision.
