Abstract:
Objective To investigate the clinical features of restless legs syndrome(RLS),its possible pathogenesis.and the effects of benserazide on the patients with RLS.Methods Twenty-three patients who met the primary diagnostic criteria of RLS were retrospectively analyzed.Results Twenty-three middle-aged or elderly patients aged 56 years in average had an average onset age of 52 years.Insomnia and daytime sleepiness were mostly common complains for these patients.Based on the diagnostic criteria of International RLS study group(IRLSSG),the average IRLSSG score was 25,and 16 cases(69%)of the patients were severe(21-30).Polysomnographic examination showed that 18 cases(78%)had periodic limb movement.in which the PLM index of 11 cases(61%)patients Was moderate(25-49).PLM-arousal index of all patients was increased.that of 16 cases(67%)patients being moderate.After treatment by levodopa/benserazide 100/25 mg at bedtime each night for 4 weeks,most of patients'subjective symptoms improved markedly.and the IRLSSG score Was obviously decreased.with an average score of 13,and 5 patients became completely normal.Among patients with periodic legs movement.the PLM index became normal in 5 patients and became mild in others.In addition.the PLM-arousal index in all patients Was markedly decreased.with that of 11 patients becoming normal.The sleep latency of 19 patients became normal.On the other hand,6 patients(26%)had transient headache,nausea,and lethargy.Conclusions Patients with discomfortable feeling of lower extremity which is mitigated after movement.and legs movement during sleep should be check up as early as possible.Benserazide may be considered as an effeetive medication for patients with RLS.
