Healthy sleep is essential for the regeneration of the body. Neurologists from Bern have now provided evidence that influencing sleep can improve recovery after a stroke.
Sleep consists of two forms of state
The team of Claudio Bassetti and Antoine Adamantidis of the University Clinic of Neurology of the University of Bern and Inselspital showed in a mouse model that slow-wave sleep induction improves motor recovery after a stroke, as announced by the hospital. university. For their study, they used optogenetics in rodents. With this technology, neural activity and brain waves can be controlled with light.
Sleep consists 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 disturbances increase the risk of stroke
Neurologist Bassetti’s team has already demonstrated the connection between sleep disorders and stroke in previous studies. According to this, sleep disturbances such as insomnia, too much sleep and breathing pauses increase the risk of stroke. Recovery after a stroke is also hampered. After a stroke, the brain also needs enough sleep to reconnect with nerve cells.
The new findings, published in the Journal of Neuroscience, indicate that recovery after a stroke could be promoted with brain stimulation or drugs that help you sleep better.
Stroke is the second leading cause of death and disability in the world. The lifetime risk of having a stroke is 25% for people over the age of 25.
