Poor sleep leads to brain aging
Author: Jonathan Warren
Changes in the duration of sleep act as a catalyst for the effects of aging on the brain according to new research.
A study of 1,459 women and 3,972 men aged between 45 and 69 reveals that brain power declines when the amount of time people spend in slumber is changed.
The study looked at the sleeping habits of participants in the period 1997 to 1999 and then re-examined them again 2002 to 2004. Cognitive power was also measured during the study using a range of tests including trials of memory, reasoning and vocabulary, the study also checked for the early signs of dementia.
Jane Ferrie, a senior research fellow from the University of London who worked on the study, emphasised the importance of a good snooze, saying: 'The main result to come out of our study was that adverse changes in sleep duration appear to be associated with poorer cognitive function in later-middle age.’
