Cambridge study finds apathy, not depression, is an early sign of dementia :

A new study, led by neuroscientists from the University of Cambridge, has identified apathy as an important early sign of dementia. The research finds apathy is distinct from depression, and offers a more accurate longitudinal association with the onset of dementia.

[...] To study this particular distinction between apathy and depression, and their relationship with dementia, the researchers looked at two independent cohorts with cerebral small vessel disease (SVD), totaling more than 450 subjects. SVD is a common age-related condition and it's the leading cause of vascular dementia, so following SVD patients for several years before dementia develops offers a good insight into the earliest pre-clinical signs of cognitive decline.

Affirming the hypothesis that apathy is an early sign of cognitive decline, the researchers reference recent MRI studies finding SVD damages specific white matter networks relating to motivation and healthy cognitive functions. This suggests as SVD progresses, an early stage of pre-dementia neurodegeneration can manifest in apathetic behavior.

"This implies that apathy is not a risk factor for dementia per se, but rather an early symptom of white matter network damage," the researchers write in the study. "Indeed, recent theoretical work proposed that certain symptoms of apathy are synonymous with defined cognitive deficits. If this is the case, then apathy may manifest early as a reduction in attention towards reward stimuli, then later, as an inability to learn or remember rewarding behaviours."
