We report a chronic and severe case of sleep-related neurogenic tachypnea that occurred after head injury and preceding the use of medications known to suppress the respiratory system. Failure to acknowledge or explain the patient's sleep behavior had previously contributed to her depression and anxiety. She accepted that her respiratory abnormality in sleep is of little prognostic significance. Her medication was not changed, and no treatment was initiated. The patient took comfort from the polysomnography evidence shown to her and was greatly reassured.
