Insomnia: An Eye Opening Study
A study of insomnia patients suggests it is a persistent condition that is hard to shake.
The research found about 75 percent of the participants experienced the inability to either fall asleep or stay asleep for at least one year, while nearly 50 percent experienced it for three years.
Insomnia is the inability to fall asleep or stay asleep. About 30 percent of adults report symptoms of insomnia and 6 to 10 percent meet the criteria for an insomnia disorder, according to the study authors. Several factors such as being female, increasing age, having anxiety or depression and experiencing pain from medical conditions have been associated with the disorder. Insomnia is also linked to higher health care costs, missing work, disability and a higher risk of hypertension and depression.
"This study provides preliminary evidence to better understand the natural course of insomnia," the study authors reported.
They added additional studies are needed to identify moderating and mediating factors of persistence, remission and relapse.
