Scientists establish link between sleep deprivation and changes in brain volume

Impact of sleep disorders on brain structure

According to the results of a scientific study, prolonged sleep deprivation leads to a physical reduction in brain volume. Such structural changes negatively affect the brain's structure.

Cognitive consequences

The reduction in brain tissue volume caused by sleep problems has specific consequences for a person's daily functioning. The main symptoms include:

• impaired memory quality;
• difficulties with concentration;
• increased irritability.

At-risk groups

Similar negative changes in brain structure are observed not only in those who simply sleep little. A similar picture is seen in patients suffering from insomnia, sleep apnoea syndrome, and sleepwalking.
