Longitudinal analysis reveals links between gray matter atrophy, white matter hyperintensities, and apathy in Parkinson's disease patients.

Longitudinal analysis shows that gray matter atrophy significantly predicts future apathy progression in Parkinson's disease.
Specifically, atrophy in brain regions like the nucleus accumbens and insula correlates with worsening apathy severity.
Greater white matter hyperintensity burden in the frontal lobe is associated with increased apathy in patients.
Findings underscore the importance of monitoring brain health to address apathy symptoms in Parkinson's disease.

Moqadam et al. (2025) studied this question.
