Healthy sleep is necessary for the recovery of the organism. Neurologists in Bern have now provided evidence that the effect of sleep can improve recovery after a stroke.
Sleep is made up of two forms of state
The team around Claudio Bassetti and Antoine Adamantidis of the University Clinic of Neurology at the University of Bern and Innspital Hospital showed in a mouse model that slow wave induction induced improved motor recovery after a stroke, according to the University Hospital. For their study, they used rodent optogenetics. With this technology, nerve activity and brain waves can be controlled with light.
Sleep is made up of two forms of state: On the one hand, REM sleep (rapid eye movement), in which dreams mainly take place. On the other hand, from non-REM sleep, which also includes slow-wave sleep. During this phase of deep sleep, the brain secretes growth hormones that help the body regenerate.
Sleep disorders increase the risk of stroke
The team around neurologist Bassetti has already shown the link between sleep disorders and strokes in previous studies. According to this, sleep disorders, such as insomnia, excessive sleep and breaks in breathing, will increase the risk of stroke. Recovery after a stroke is also impaired. After a stroke, the brain also needs enough sleep to re-establish contact with nerve cells.
New findings, published in the Journal of Neuroscience, suggest that recovery from a stroke may be promoted by brain stimulation or drugs that contribute to better sleep.
Stroke is the second leading cause of death and disability worldwide. The lifetime risk of stroke is 25 percent in people over the age of 25.
