Size of the brain’s memory centre indicates risk of dementia with Lewy bodies

A US study of people with mild memory and thinking problems suggests that monitoring the size of a brain structure called the hippocampus could indicate the specific cause of dementia in those who develop the condition later in life. The research, published today (November 2) in the journal Neurology, shows that the hippocampus is much less likely to shrink in those who later have dementia with Lewy bodies compared to those who go on to develop Alzheimer’s disease.
