Sleep and quantitative EEG in neurodegenerative disorders
Petit D, Gagnon JF, Fantini ML, Ferini-Strambi L, Montplaisir J.. Journal of psychosomatic research, 2004-05-01
Topic: Risk, prevention and care in population studies
This paper reviews current knowledge on sleep problems, sleep architecture changes and quantitative EEG alteration brought on by various neurodegenerative diseases, such as Alzheimer's disease (AD), progressive supranuclear palsy (PSP), REM sleep behavior disorder (RBD), Parkinson's disease (PD), dementia with Lewy bodies (DLB), multiple system atrophy MSA, Huntington's disease and Creutzfeldt-Jakob disease, in comparison to normal aging. The study of sleep variables and that of the spectral composition of the EEG can provide valuable information for understanding the pathophysiology and for assisting the diagnosis of neurodegenerative diseases.

Key findings
- This paper reviews current knowledge on sleep problems, sleep architecture changes and quantitative EEG alteration brought on by various neurodegenerative diseases, such as Alzheimer's disease (AD), progressive supranuclear palsy (PSP), REM sleep behavior disorder (RBD), Parkinson's disease (PD), dementia with Lewy bodies (DLB), multiple system atrophy MSA, Huntington's disease and Creutzfeldt-Jakob disease, in comparison to normal aging.
- The study of sleep variables and that of the spectral composition of the EEG can provide valuable information for understanding the pathophysiology and for assisting the diagnosis of neurodegenerative diseases.
Why it matters
This review describes how sleep problems, changes in sleep architecture, and quantitative EEG changes occur in Alzheimer's disease and other neurodegenerative diseases compared with normal aging. It suggests that studying sleep and EEG may help understand these diseases and assist with diagnosis, but it does not report any treatment or cure.
