BACKGROUND The pathophysiology of periodic limb movements in sleep (PLMS) in restless legs syndrome (RLS) is unclear. OBJECTIVE The authors neurophysiologically investigated PLMS in patients with idiopathic RLS in order to obtain information on the origin and pathophysiology of the movements. METHODS Ten patients with idiopathic RLS underwent(More)
A case of stiff-man syndrome associated with primary generalised epilepsy is reported. In addition, nocturnal polygraphic recording revealed a nocturnal myoclonus. Detailed examination of the central nervous system did not show specific changes. There is no direct proof as to a spinal or supraspinal origin of the stiff-man syndrome. The absence of specific(More)
The aim of the study was to determine the clinical frequency and features of REM sleep behaviour disorder (RBD) in a large population of Parkinson's disease (PD) patients using defined diagnostic criteria both for RBD and PD. Six trained neurologists used a semistructured questionnaire based on ICSD-R diagnostic criteria for RBD to evaluate 200 PD patients(More)
A case of myotonic dystrophy accompanied by alveolar hypoventilation and hypersomnia is presented. Radiological studies and EMG examination of the intercostal muscles demonstrated that the respiratory muscles were affected by the disease, while polygraphic recordings showed that the alveolar hypoventilation and pulmonary hypertension worsened during sleep.(More)
Respiratory failure has been described in myotonic dystrophy; it worsens during sleep but its central or peripheral origin has yet to be determined. Moreover, patients may present severely disturbed sleep and daytime somnolence. Eight patients with mild to moderate myotonic dystrophy were studied to assess breathing function while awake and during sleep by(More)
The sleep-related respiratory and blood pressure changes in a patient with Shy-Drager syndrome associated with the sleep apnoea syndrome are reported. Polygraphic recordings showed repeated apnoeic episodes during both sleep and wakefulness. Systemic arterial pressure values during sleep tended to be lower than in two other patients with Shy-Drager(More)
Nocturnal myoclonus (or periodic movements in sleep) consists of stereotyped sleep-related movements of the lower limbs and occasionally also upper limbs, ranging from simple dorsiflexion of the big toe and foot to a triple flexion of the entire leg. It is characterized by a typical periodicity, often occurring in association with sleep arousal phenomena.(More)
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(More)
