Poor sleepers have smaller brains - learn.
Scientists analyzed the results of several dozen MRI studies among people with various sleep disorders: insomnia, apnea, sleep walking and others.
As a result, repeated signs of a decrease in the volume and density of brain tissue were found in the left thalamus region, a structure involved in the control of attention and information processing. A decrease was also recorded in the posterior cerebral cortex, which is associated with decision-making and motivation. These areas are part of large networks of neurons, the dysfunction of which can lead to cognitive and emotional problems.
The authors suggest that the changes found may explain why people with sleep disorders react more slowly and are more likely to make mistakes.
