Description
Roberta Lizio and eleven co-authors study brain rhythms in three forms of dementia in a 2025 paper on the resting alpha rhythm. They measured how much the alpha rhythm at the back of the brain drops when a person opens their eyes. That drop, called reactivity, shows how well the brain raises its alertness, and the team suspected it differs by disease.
Data came from thirty-five patients with Alzheimer's disease, sixty-five with Parkinson's disease dementia, thirty with Lewy body dementia, and twenty-five healthy older adults. A strong drop appeared in most healthy seniors, in about half of the Alzheimer's and Lewy body groups, and in just over a third of the Parkinson's group. The drop was weakest at the back of the brain in the Parkinson's group. The authors propose the measure as a marker for trials of treatments that aim to improve alertness.
