Sleep disorder that includes difficulty initiating sleep, maintaining sleep, and/or waking too early despite adequate opportunity and circumstances. The alteration in the quality or quantity of sleep leads to deficits in the person's daytime functioning.
Several factors have been described that may contribute to this, such as stress, pain, psychiatric disorders, alcohol abuse, etc.
The most common symptoms are: difficulty in sustaining attention, fatigue and irritability and may lead to an increase in errors or accidents at work.
Diagnosis is made clinically by interview and physical examination. It may be necessary to carry out specific tests to investigate the cause, such as polysomnography if sleep apnoea is suspected.
Treatment is based on establishing regular sleeping habits. Medication may be used in cases that are more difficult to treat.
