Relationship between sleep deprivation and urinary MHPG levels
A 5-day study, forming the initial part of two 32-day clinical trials and involving 22 unipolar depressed inpatients, was designed to determine the relationship between response to sleep deprivation and 24-hour urinary MHPG levels. A statistically significant, positive relationship was noted between the sleep deprivation, modified total HAM-D scores and MHPG levels at postsleep deprivation, indicating that the greater the severity of depression during sleep deprivation the higher were the MHPG levels after the sleep deprivation period.
