A 15-year-old girl developed a prominent delayed sleep phase syndrome (DSPS) following traumatic brain injury. Several physiological markers of the sleep-wake rhythm: plasma melatonin, body temperature, wrist activity and sleep architecture (EEG) were delayed almost half a day, returning to normal after treatment with 5 mg melatonin. This report suggests an association between traumatic brain injury and DSPS. Awareness of this phenomenon may result in better possibilities for treatment of patients with brain injury.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Valproate versus flunarizine in migraine prophylaxis: a randomized, double-open, clinical trial.
The aim of this study was to compare the efficacy and safety of valproate versus flunarizine in migraine prophylaxis in a randomized double-open clinical trial. Twenty-two migraine sufferers were treated with valproate (1 g per day) for 8 weeks; a parallel group of 22 migraine sufferers was treated with flunarizine (10 mg per day). The main admission criterion was a minimum of 3 migraine (with, or without aura) attacks per month. ⋯ In the valproate group 12 patients (57.1%) reported various side effects (prevalently gastric symptoms) versus 10 patients (47.6%) in the flunarizine group (prevalently somnolence). The patients who were treated with flunarizine showed an increase in the mean score of the 21-item Hamilton rating scale for depression, but the difference was not significant; morning dysthymia however, was significantly more often observed in the flunarizine patients, compared to the valproate patients. These results suggest that both drugs are effective and safe in migraine prophylaxis.

The architecture of nocturnal sleep in twenty subjects (9 males, 11 females, mean age 27 years) affected by partial cryptogenic epilepsy was investigated by means of ambulatory EEG (A-EEG) recording performed at home. The study aimed in particular to ascertain the immediate effects of nocturnal partial epileptic seizures on sleep stability and continuity. Data for a total of 49 recorded seizures indicate that 72% of the partial seizures which occurred during sleep were followed by arousal and awakening, and that sleep interruption lasted significantly longer when the seizure occurred between 4 and 7 a.m.

Greater occipital nerve (GON), supraorbital nerve (SON), and minor occipital nerve (MON) blockades-in this sequence-were carried out on the symptomatic side in patients with chronic paroxysmal hemicrania (CPH) (no = 6) and hemicrania continua (HC) (no = 7). Prior to the blockade, indomethacin was discontinued for a sufficiently long time (24 h) to allow a constant flow of attacks/constant pain. The local anaesthetic agent used was lidocaine. ⋯ GON/MON blockades will help distinguish CPH/HC from cervicogenic headache. SON blockade will have to be carried out in a good-sized series of HC patients in order to establish more concrete evidence of the putative effect in HC. SON blockades may eventually also aid in the distinction between HC and supraorbital nerve neuralgia (where the blockade effect generally seems to be complete).
