The evolution of dementia is strongly related to cognitive, motor, and functional changes and to the presence of cardiovascular diseases. Disturbances vary according to phase of dementia and can limit instrumental and basic activities of daily living. The aim of this study was to analyze the immediate physiological effects of listening to music before physical exercise in institutionalized older people with moderate to advanced dementia. A randomized trial was conducted with 18 institutionalized older people with dementia (mean age was 79 years old, 52.6% were female), who were divided into a Training with Music Group (TWMG) and a Training without Music Group (TWtMG). The evaluation included heart rate (HR), blood pressure (BP) and HR variability (HRV). The assessment was conducted in a closed environment or in places with minimal visual and auditory stimulation. The TWMG was submitted to stimuli with music for 15 minutes and physical exercises for 30 minutes to improve/maintain their global mobility. The TWtMG performed the same physical exercises, however without music before physical exercise. The interventions lasted 12 weeks, and were performed individually once a week. In the TWMG, we observe a decrease in diastolic BP in the third session. In the sixth week, the HR increased after the session in both groups. TWMG improved HRV in the third session, with a difference between groups only after the session. After the sixth session, HRV values improved in both groups. In conclusion, listening to music before physical exercise is associated with positive effects in people with dementia, as it tends to maintain and improve physiological factors.
Na última fase da demência, torna-se comum a institucionalização devido à dificuldade de relacionamento e cuidado. O objetivo do estudo foi verificar a presença de distúrbios comportamentais, funcionais e cognitivos de idosos institucionalizados com demência e analisar de forma prospectiva os fatores funcionais, a fase da demência e a taxa de óbito e quedas ao longo de 8 meses destes idosos. Trata-se de um estudo longitudinal, que ocorreu em dois momentos de avaliação (inicial e após 8 meses), com idosos institucionalizados com demência. Inicialmente, os participantes foram submetidos a uma avaliação envolvendo fatores comportamentais (expressões faciais, Inventário Neuropsiquiátrico, variáveis cardiovasculares), instrumentos funcionais e cognitivos. Ao longo de 8 meses, uma vez por mês era solicitado à equipe o registro da taxa de quedas. Após 8 meses, os participantes foram submetidos à avaliação funcional e à fase de demência, além do registro de óbitos. Como resultados principais, foi observada presença de baixa variabilidade de frequência cardíaca e distúrbios comportamentais, cognitivos e funcionais. Os idosos apresentaram aumento da taxa de quedas, piora significativa do quadro funcional e aumento do número de idosos classificados com demência avançada. Os resultados acompanham a progressividade característica da demência. Como conclusão, faz-se importante o relato de quedas com intuito de identificar os fatores de risco para e assim poder agir com antecedência.
