Excluding people with depression symptoms did not change the results. ![]() The study found that people with two or more apathy symptoms had 1.4 percent smaller gray matter volume and 1.6 percent less white matter volume compared to those who had less than two symptoms of apathy. They were also asked questions that measure apathy symptoms, which include lack of interest, lack of emotion, dropping activities and interests, preferring to stay at home and having a lack of energy. Brain volume losses occur during normal aging, but in this study, larger amounts of brain volume loss could indicate brain diseases.įor the study, 4,354 people without dementia and with an average age of 76 underwent an MRI scan. Launer’s team used brain volume as a measure of accelerated brain aging. And the fact that participants in our study had apathy without depression should turn our attention to how apathy alone could indicate brain disease.” “Apathy symptoms are common in older people without dementia. Launer, PhD, with the National Institute on Aging at the National Institutes of Health (NIH) in Bethesda, MD, and a member of the American Academy of Neurology. “Just as signs of memory loss may signal brain changes related to brain disease, apathy may indicate underlying changes,” said Lenore J. ![]() Older people who have apathy but not depression may have smaller brain volumes than those without apathy, according to a new study published in the April 16, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
