Mark Hallett and the renaissance of functional neurological disorder.
Review in Clinical parkinsonism & related disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This article traces the contributions of Mark Hallett (1943-2025) to Functional Neurological Disorder (FND) from 2003 to his death. Mark brought his expertise in motor physiology, free will, volition and agency to this neglected but common condition. He raised awareness of our need to understand its pathophysiology, natural history and treatment, and then became a key researcher investigating abnormalities of brain networks found in individuals with the condition, as well as its multifactorial aetiology. He played a pivotal role in organising international meetings and books on functional movement disorder and FND, culminating in his role as the first president of the International FND Society (2019-2022). In 2024, Mark Hallett gave the 2024 American Academy of Neurology Wartenberg lecture, recalling "la lésion dynamique" proposed by Charcot as the pathophysiology of FND in the 19th century. This lecture was emblematic of the renaissance of interest in FND after a long period of neglect and his huge contribution to our understanding of the disorder.
