Uncovering hypothalamic network disruption in ALS.
Article in Journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStructural 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.
methodsSeventy-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.
resultsALS 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.
conclusionsThese findings support hypothalamic alterations in ALS. Early detection of hypothalamic changes could be useful in prognostic stratification and evaluating intervention effects.
