It is a sleep disorder that includes difficulty initiating sleep, maintaining sleep and/or waking up too early, despite adequate opportunity and circumstances. The alteration of the quality or quantity of sleep leads to deficits in the person's daytime functioning.
Multiple factors have been described that may favor this, such as stress, pain, psychiatric disorders, alcohol abuse, etc.
The most common symptoms include: difficulty in maintaining attention, fatigue and irritability and can lead to an increase in errors or accidents at work.
Diagnosis is clinical by questioning and physical examination. It may be necessary to perform specific tests to study the cause, for example, polysomnography if sleep apnea syndrome is suspected.
Treatment is based on establishing regular sleep habits. In more difficult-to-treat cases, drugs may be added.
