Sleep disorder is a type of sleep-related problem that causes difficulty in falling asleep, staying asleep, or both.
There are many factors which can cause sleep disorder like stress, depression, anxiety, and other mental health disorders.
Sleep disorder is also caused by medical problems such as insomnia, restless leg syndrome (RLS), and sleep apnea.
The symptoms of sleep disorder are daytime fatigue or drowsiness; trouble concentrating; irritability or mood swings; changes in appetite; and/or trouble remembering recent events.
The diagnosis for this type of sleep problem is usually done with a physical examination and an interview with the patient about their symptoms. In some cases doctors may order tests to rule out other conditions that could be causing the symptoms.
