Sleep is essential for us but also for our brain. A team of scientists from the universities of Oxford and Oslo has resolved in his last job, apart from lack of sleep accelerates the aging brain, also alters its size, decreasing brain volume.

The findings, which are published in the journal Neurology, detailed an experiment with 147 adults between 20 and 84 years of age who examined thoroughly in order to compare their difficulties with sleep with brain volume. Thus, participants underwent MRIs every 3.5 years and completed a questionnaire about sleep habits.

The results revealed that difficulties in falling asleep were related to a much faster than normal overall brain volume decline, being more severe in people over 60 years.

"It is not yet known whether poor sleep quality is a cause or a consequence of changes in brain structure. There are effective treatments of sleep disorders, so that, in future research, it would have to check whether improved sleep quality can reduce the rate of brain volume loss. If so, improved sleep habits may be important for improving brain health means "says Claire E. Sexton, who led the study.
