REM sleep behavioral disorders.

REM sleep behaviors were recently described as wild, dream-enacting behaviors during REM sleep with loss of usual atonia on submental muscles. We examined 6 patients (5 M, 1F) with characteristic episodes of behavioral manifestations during REM sleep. Polysomnographic data indicate a decrease in first REM latency, an absence of stage 4 NREM, altered phasic motor activity and behavioral episodes during REM sleep even with normal chin muscle atonia. Three patients had Shy-Drager syndrome, 1 olivopontocerebellar atrophy and 2 patients had no neurological disease. The crucial importance of a disinhibited locomotor system during sleep appears to be responsible for this REM parasomnia.

Nocturnal myoclonus in restless legs syndrome effect of carbamazepine treatment.

We studied Restless Legs Syndrome (RLS) and nocturnal myoclonus (NM) in 9 patients before and after carbamazepine treatment, to verify the correlation between improvement of RLS and modification of NM pattern during sleep. Although CBZ proved effective in the treatment of RLS, it did not modify the pattern of nocturnal myoclonus and its relationship to arousal during sleep. The efficacy of CBZ on RLS may be due to other properties of the drug rather than to the effect on nocturnal sleep: reduction of sleep latency and wakefulness after sleep onset.

Breathing impairment in central alveolar hypoventilation and Rett syndrome.

Breathing is regulated by the behavioural and the automatic systems, the former mainly acting during wakefulness, the latter during sleep. Central alveolar hypoventilation and breathing disorders in Rett syndrome indicate a selective impairment of the two systems.
