Sleeping problems are common in many other disorders as well, including Alzheimer's disease, stroke, cancer, and head injury. These sleeping problems may arise from changes in the brain regions and neurotransmitters that control sleep, or from the drugs used to control symptoms of other disorders.
Your doctor might be able to diagnose a sleep disorder based on your sleep schedule and habits. However, he or she also might need the results from sleep studies and other medical tests to diagnose a sleep disorder. Sleep studies can help diagnose: 1  Sleep-related breathing disorders, such as sleep apnea. 2  Sleep-related seizure disorders. 3  Sleep-related movement disorders, such as periodic limb movement disorder. 4  Sleep disorders that cause extreme daytime tiredness, such as narcolepsy.
