RESUMEN

OBJECTIVE: To investigate the relationships between quality of life (QOL) and clinical and electroencephalogram (EEG) aspects in patients with Alzheimer's disease (AD). METHOD: Twenty-eight patients with mild or moderate AD, 31 with Parkinson's disease (PD), and 27 normal controls (NC) were submitted to: CERAD neuropsychological battery, Hamilton Depression and Anxiety Rating Scales, Functional Activities Questionnaire, QOL scale for patients with AD, and quantitative EEG measures. RESULTS: AD and PD patients had similar QOL (31.0 ± 5.8; 31.7 ± 4.8, respectively), worse than that of NC (37.5 ± 6.3). AD patients had lower global interhemispheric theta coherence (0.49 ± 0.04; 0.52 ± 0.05; 0.52 ± 0.05; respectively) than PD and NC. Multiple linear regression for QOL of AD patients revealed that global interhemispheric theta coherence, and Hamilton depression scores were significant factors (coefficients; 58.2 and -0.27, respectively; R2, 0.377). CONCLUSION: Interhemispheric coherence correlates with QOL regardless of cognitive and functional variables and seems to be a neurophysiological indicator of QOL in AD patients.

RESUMEN

Objective To investigate the relationships between quality of life (QOL) and clinical and electroencephalogram (EEG) aspects in patients with Alzheimer’s disease (AD). Method Twenty-eight patients with mild or moderate AD, 31 with Parkinson’s disease (PD), and 27 normal controls (NC) were submitted to: CERAD neuropsychological battery, Hamilton Depression and Anxiety Rating Scales, Functional Activities Questionnaire, QOL scale for patients with AD, and quantitative EEG measures. Results AD and PD patients had similar QOL (31.0 ± 5.8; 31.7 ± 4.8, respectively), worse than that of NC (37.5 ± 6.3). AD patients had lower global interhemispheric theta coherence (0.49 ± 0.04; 0.52 ± 0.05; 0.52 ± 0.05; respectively) than PD and NC. Multiple linear regression for QOL of AD patients revealed that global interhemispheric theta coherence, and Hamilton depression scores were significant factors (coefficients; 58.2 and -0.27, respectively; R2, 0.377).

Objetivo Investigar relações entre qualidade de vida (QV) e aspectos clínico-eletrencefalográficos (EEG) em pacientes com doença de Alzheimer (DA). Método Vinte e oito pacientes com DA, 31 com doença de Parkinson (DP) e 27 controles normais (CN) foram submetidos a avaliações neurocognitivas, escala de depressão de Hamilton e de qualidade de vida para pacientes com DA, questionário de atividades funcionais e medidas do EEG. Resultados A QV foi similar nos grupos DA e DP (31,0 ± 5,8; 31,7 ± 4,8, respectivamente), mas inferior ao CN (37,5 ± 6,3). No grupo DA houve menor coerência inter-hemisférica global teta (CIGT) do que em DP e CN (p < 0,05). Regressão múltipla linear para QV no grupo DA revelou a CIGT e a escala de Hamilton como fatores significativos (coeficientes; 58,2; -0,27, respectivamente; R2, 0,377). Conclusão A CIGT correlaciona-se com a QV independentemente de variáveis cognitivas e funcionais e parece ser um indicador neurofisológico da QV em pacientes com DA. .
