Transient Ischemic Attacks and Minor Stroke During Sleep Relationship to Obstructive Sleep Apnea Syndrome
1995
Background It is reported that 13% to 44% of all cerebrovascular accidents (CVAs) occur during sleep. In addition to other well-known risk factors, snoring, sleep apnea, obesity, and daytime sleepiness have been shown to significantly increase the risk of stroke. We describe two cases that support the statistical relationship between snoring, sleep apnea, and CVA during sleep. Case Descriptions In the first case, motor aphasia was noted in a 64-year-old, 5-ft, 1-in, 218-lb woman when she awakened from sleep at approximately 4 am. This completely resolved within 3 hours. During her subsequent hospitalization she was found to have severe obstructive sleep apnea that responded well to treatment with nasal continuous positive airway pressure. There has been no recurrence of symptoms in this patient. The second patient was a 59-year-old, 5-ft, 6-in, 260-lb woman who presented to the Sleep Disorders Center with signs and symptoms of severe sleep apnea. In addition, she had awakened from sleep approximately 6 mo...
