Sleep Problems Strongly Linked to Psychiatric Disorders
A recent study conducted by Harvard Medical School and the University of California at Berkley has linked sleep deprivation with psychiatric disorders. Due to lack of sleep the brain can become abnormally emotional, which undermines a range of functions. The researchers conducted a study on 35 volunteer-participants whom lacked sleep up to 35 hours. Through the use of an MRI, the researchers discovered that the amygdala (part of the brain linked to emotional reactions) showed 60% higher reactions to images that stimulated happy or sad emotions than individuals whom had adequate amounts of sleep. The following is an excerpt of an article from Medical News Today that reviews the study:
The size of the increase really surprised us,” commented researcher Matthew Walker. “It is almost as though, without sleep, the brain reverts back to a more primitive pattern of activity, becoming unable to put emotional experiences into context and produce controlled, appropriate responses.” He believes there may well be a link between sleep deprivation/disorders and psychiatric disorders. He added that previous studies had indicated that most patients with psychiatric disorders also suffer from some kind of sleep disorder.
