Sleep disorders, also known as sleep-wake disorders, involve issues with the quality, timing, and amount of sleep, leading to daytime distress and impaired functioning. These disorders often coexist with medical conditions or other mental health issues, such as depression, anxiety, or cognitive disorders.
Signs and symptoms of sleep disorders include excessive daytime sleepiness, irregular breathing, or increased movement during sleep. Other signs and symptoms may involve irregular sleep-wake cycles and difficulty falling asleep.
There are various types of sleep disorders, which can be categorized based on the reasons for their occurrence or how they affect individuals. They can also be grouped according to behaviors, problems with natural sleep-wake cycles, breathing issues, and difficulty sleeping.
