What Are the Different Sleep Disorder Symptoms?
Common sleep disorder symptoms include excessive sleepiness during the daytime, irritability, difficulty concentrating, and memory loss. Such symptoms tend to be caused by abnormal sleep cycles. An abnormal cycle could be marked by a consistent, but unrestful sleep, or by an inability to sleep at night. Many sleep disorder symptoms, such as extreme absentmindedness, are highly noticeable, but others, such as merely feeling tired throughout the day, are more subtle and may not be properly understood as a symptom of a sleep disorder.
