Primary care doctor: Because of the patient’s age and theabsence of a headache history, I first considered such secondarycauses as tumor and temporal arteritis. However,MRI of the brain and erythrocyte sedimentation rate werenormal. I now suspect a sleep-related headache becausethe attacks occur only at night and awaken the patientfrom a sound sleep. How can I determine which type ofsleep-related headache is involved?
