Key Points

To quantify hypothalamic volumes in progressive supranuclear palsy (PSP) using automatic segmentation methods.
Utilized convolutional neural network (CNN) for brain imaging analysis.
Compared hypothalamus volumes between PSP patients, controls, and Parkinson's disease (PD) patients.
Showed significantly reduced hypothalamus volumes in PSP patients compared to controls.
Findings suggest potential metabolic profiles may correlate with hypothalamic atrophy in PSP.

Abstract

The CNN-based hypothalamus volume quantification study demonstrated significantly reduced hypothalamus volumes in PSP patients compared to controls and PD, respectively; future studies will address the metabolic profiles of PSP as potential functional correlates.
