Disturbed sleep is widely regarded as one of the characteristics of Alzheimer’s disease. So there is an obvious question: Are any forms of disturbed sleep occurring before the onset of Alzheimer’s predictive of the later onset of the disease? Four studies set out to examine the relationship between different aspects of sleep disturbance and the later onset of Alzheimer’s. All of the studies showed some correlation between the studied aspect of sleep disturbance and the latter occurrence of Alzheimer’s.
Below, we provide links to a media article on each of the studies, together with a link to the main research article (or an abstract):
