What Causes Apathy in Seniors?

Apathy is a common neuropsychiatric symptom in Alzheimer’s disease dementia and amnestic mild cognitive impairment and is associated with cortical atrophy in Alzheimer’s disease dementia. A new study published in The Journal of Neuropsychiatry and Clinical Neurosciences investigated possible correlations between apathy and cortical atrophy in 47 individuals with mild cognitive impairment and 19 clinically normal elderly. Backward elimination multivariate linear regression was used to evaluate the cross-sectional relationship between scores on the Apathy Evaluation Scale and thickness of several cortical regions and covariates. Lower inferior temporal cortical thickness was predictive of greater apathy. Greater anterior cingulate cortical thickness was also predictive of greater apathy, suggesting an underlying reactive process.
