USPSYCH: Insomnia May Signal More Mental Health Disorders to Come
Often it is assumed that insomnia is the result of a mental health issue rather than the other way around. However, a recent study concluded that the opposite might be true in many cases. According to Jeffery Nard, MD, of Eastern Virginia Medical School in Norfolk, “…insomnia preceded the mood disorder about 40% of the time, and it was concurrent with the disorder about 30% of the time.” The following is an excerpt of the article:
Although anxiety often precedes insomnia — keeping patients tossing and turning at night — about 15% of those with an anxiety disorder reported having insomnia first, the same study found, Dr. Nard said.
Furthermore, in another study that followed about 1,000 randomly-selected HMO patients for three years, those with insomnia were nearly four times more likely to be newly diagnosed with major depression and nearly twice as likely to be diagnosed with an anxiety disorder, Dr. Nard said.
