Aspectos poligráficos dos movimentos periódicos do sono

Polygraphic aspects of periodic movements in sleep

Resumos

Cem pacientes avaliados seqüencialmente em um laboratório de sono foram analisados quanto a presença de movimentos periódicos do sono (MPS), ou seja, mioclônias noturnas. O critério utilizado para considerar MPS foi ter 5 ou mais movimentos mioclônicos por hora de sono e 18 pacientes se incluiram nesta categoria. Foram comparados os acometidos de MPS com os demais. Pacientes com MPS tendiam a ser de idade mais avançada. Os movimentos foram observados no estágio 2 sendo menos vistos nos estágios 3,1,4 e REM. Os indivíduos com MPS tinham geralmente maior número de despertares parciais e de complexos K. Não houve diferença entre cs pacientes com MPS e os demais no que tange ao sexo, queixas principais, eficiência do sono, tempo total de sono, tempo que permanece em cada estágio e diagnóstico final.


One hundred patients were analyzed sequentialy regarding to the presence of periodic movements in sleep (PMS) or nocturnal myoclonus. The criteria for considering PMS was the presence of 5 or more myoclonic movements per hour of sleep. The 18 patients included in the PMS cathegory were compared with the remaining 82. Those with PMS had tendency to be older than the others. The movements were observed in stage 2 and less commonly in stages 3,1,4 and REM. Patients with PMS had generally higher number of arousals and Κ complexes. There was no difference between both groups regarding sex, history complaints, sleep efficiency, total sleep time, time in each stage and final diagnosis.
