Too little sleep and an excessive amount of affects memory.

A bunch of girls participating within the Nurses' Health Study were asked about their sleep habits in 1986 and 2000 and were interviewed 3 times over a subsequent six-year period about memory and considering skills. . DeVore and colleagues observed worse performance on mental tests in women who slept five hours or less or nine hours or more each night, in comparison with those that slept seven to eight hours. Their results were published online. Journal of the American Geriatrics Society.

The researchers estimated that girls who got less sleep and people who got more sleep were two years older mentally than women who got seven to eight hours of shut-eye an evening.

Beyond memory

While the study couldn't prove that getting too little or an excessive amount of sleep causes memory and considering problems, it's consistent with other work showing the potential harmful effects of poor sleep. Previous research has linked poor sleep to higher risks of heart disease and stroke, type 2 diabetes and depression.

How can sleep affect memory? People who're continually deprived of sleep usually tend to develop hypertension, diabetes and narrowing of the blood vessels. Each of those can reduce blood flow to the brain. Brain cells need quite a lot of oxygen and sugar, so problems with blood flow can affect their ability to operate properly.

Poor sleep can affect the brain in other ways. Sleep-deprived mice produced more deposits of a protein called beta-amyloid within the brain than mice allowed to sleep normally. In humans, beta-amyloid deposits within the brain are linked to memory and considering decline and in addition increase the chance of dementia.

What about individuals who sleep an excessive amount of? People who spend greater than 9 or 10 hours an evening in bed often have less sleep. Quality. So for each too little and an excessive amount of sleep, the critical number could also be quality sleep hours.

Another possibility is a two-way street between sleep and memory: sleep quality can affect memory and considering, and brain changes that result in memory and considering problems can disrupt sleep.
