Abstract: Structural MRI studies have shown hypothalamic atrophy and altered white matter (WM) connectivity in amyotrophic lateral sclerosis (ALS), as a possible substrate of hypermetabolism in this condition. However, hypothalamic functional connectivity and its association with clinical features in ALS remain unclear. This study explored hypothalamic resting-state functional connectivity (RS-FC) in ALS patients compared to controls and its relationship with disease severity defined by the ALS Functional Rating Scale (ALSFRS-r), body mass index (BMI), disease duration, progression rate, survival, hypothalamic volume, and WM integrity.Seventy-one ALS patients and 39 healthy controls underwent structural and RS functional MRI. The bilateral hypothalamus was segmented, and a seed-based RS-FC analysis was performed. Group differences in hypothalamic RS-FC and their correlations with ALSFRS-r scores, BMI, disease duration, progression rate, survival, hypothalamic volume, and WM integrity were assessed. Tract-based spatial statistics was performed to estimate the correlation between WM damage in ALS and hypothalamic RS-FC.ALS patients showed increased hypothalamic RS-FC with caudate nuclei compared to controls. Additionally, greater disease severity correlated with increased hypothalamic RS-FC with the caudate nuclei and orbitofrontal cortex. Hypothalamic RS-FC mean values also associated with FA in the genu of corpus callosum and forceps minor and disease progression rate. No significant correlations were observed with other clinical features.These findings support hypothalamic alterations in ALS. Early detection of hypothalamic changes could be useful in prognostic stratification and evaluating intervention effects.
