Theory of Mind in multiple system atrophy: comparison with Parkinson's disease and healthy subjects.

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
Theory of Mind is defined as the ability to attribute mental state and emotions to other people and is relevant to social relationships. The cortical and subcortical regions involved in Theory of Mind are damaged by neurodegenerative processes of Parkinsonian syndromes, so the aim of the present study was to explore, for the first time, possible deficits of Theory of Mind and their cognitive correlates in multiple system atrophy (MSA). Twenty-six patients with MSA, 25 patients with Parkinson's disease (PD) and 25 healthy subjects were enrolled. Cognitive and affective subcomponents of Theory of Mind, executive functions, long-term memory and apathy were evaluated. The three groups did not differ on demographic variables. MSA and PD groups performed worse than healthy subjects on both cognitive (advanced test of ToM) and affective (emotion attribution task) ToM tasks, but no significant difference was found between patients' groups. However, when using another affective ToM task (Eyes Test), MSA group had poorer performance than healthy subjects and Parkinsonian patients, whereas Parkinsonian patients had similar performance to healthy subjects. Regression analysis revealed an association between poor cognitive flexibility and dysfunctional cognitive component of Theory of Mind. Deficit of cognitive and affective components of Theory of Mind occurred in MSA. Dysfunction of cognitive component was related to executive dysfunction (i.e. cognitive rigidity). These findings might suggest the usefulness of an early evaluation of social cognition in MSA to identify individuals with impaired Theory of Mind who are at risk of social withdrawal, and reduced quality of life.
