Arousals and periodic leg movements during sleep stages and mild cognitive impairment in older adults: a preliminary study

Sleep fragmentation may be associated with several diseases, including dementia. In this sense, sleep fragmentation, indicated by the rates of arousals and/or periodic leg movements (PLM), could be an early marker of Mild Cognitive Impairment (MCI), a syndromic stage prior to dementia. Therefore, th...

In this sense, sleep fragmentation, indicated by the rates of arousals and/or periodic leg movements (PLM), could be an early marker of Mild Cognitive Impairment (MCI), a syndromic stage prior to dementia. Therefore, the objective of this study was to compare the index of PLM with that of arousals and correlate both indexes in people with MCI and without MCI during all sleep stages. In 9 participants (3 control women and 3 women with MCI; and 3 men with MCI) (ages: 69.1 ± 5; years of education: 8 ± 2), one night of polysomnography was performed. Hourly rates of arousals and PLM were scored from each sleep stage. Analyses were performed within and between PLM and arousals for each group. Significant differences and a positive correlation were found between the arousal and the PLM rates for the group with MCI during the whole night. Knowledge of the prevalence and the association of both phenomena may contribute to a more careful and thorough evaluation of older adults at risk of developing MCI and/or dementia. La fragmentación del sueño puede asociarse con distintas enfermedades, entre ellas, la demencia. En este sentido, la fragmentación de sueño, indicada por el índice de alertamientos y/o movimientos periódicos de las piernas (MPP), podría ser un marcador temprano de deterioro cognitivo leve (DCL), un síndrome precursor de la demencia. El objetivo del presente estudio fue medir el índice de prevalencia de los alertamientos y de los MPP durante el sueño en un grupo control y un grupo con DCL, así como determinar si hay diferencia entre los grupos en ambos índices y establecer si existe una correlación entre los dos fenómenos. En 9 participantes (3 mujeres controles y 3 mujeres con DCL; y 3 hombres con DCL) (edad: 69.1 ± 5; años de educación: 8 ± 2) se registró una noche de polisomnografía. Se obtuvieron los índices por hora de alertamientos y para cada etapa de sueño, así como los MPP globales y por hora; además se realizaron análisis entre y dentro de cada grupo. Se encontró una correlación positiva y un mayor número de MPP que de alertamientos durante toda la noche en los participantes con DCL. Conocer la prevalencia y asociación de ambos fenómenos contribuye en la formulación de una evaluación más cuidadosa y profunda de los adultos mayores en riesgo de desarrollar DCL y/o demencia.
