More Than Simple Snoring Unlike short-term sleeplessness, chronic insomnia is often a symptom of a serious underlying medical disorder. Depression and other psychiatric disorders account for many cases of insomnia, as do wholly physical illnesses, such as asthma, arthritis, Parkinson's disease, kidney or heart disease, and hyperthyroidism.

It was a classic case. Obstructive sleep apnea is by far the most common type.
