Elevated autistic features in Parkinson's disease and other motor disorders.

PMID 40856532WHAT IT FOUND
Autistic traits were elevated in both Parkinson's and other motor disorders compared to controls.
The difference was specific to males; females showed no group differences. This suggests a broad link between motor conditions and autistic features, not one unique to Parkinson's.
Key findings
01Individuals with Parkinson's disease and other motor disorders scored significantly higher on autistic traits than age-matched controls, but there was no significant difference between the two clinical groups.
02When stratified by sex, male patients with Parkinson's had significantly higher autistic traits than controls, whereas no significant diagnostic group differences were found among females.
03Severity of Parkinson's motor symptoms did not predict autistic trait scores, suggesting the link is not simply due to motor impairment severity.

What it does not show
The study used a questionnaire (AQ-S) to measure autistic traits, which may not capture the full complexity of autism or distinguish it from other conditions. The design was cross-sectional, so it cannot determine whether motor disorders lead to elevated autistic traits or if they share a common cause. The 'other motor disorders' group was clinically heterogeneous, making it difficult to pinpoint which specific conditions drove the findings. Cognitive impairment was common in the clinical groups, and although MoCA scores were included as a covariate, this may not fully account for its impact on self-report or caregiver-report accuracy.
Declared interests
The authors declared no potential conflicts of interest. The study was supported by non-U.S. government funding.
The easy way to misread this
Do not assume that elevated autistic traits in motor disorders are specific to Parkinson's disease. The study found similar levels of autistic traits in patients with other motor disorders, suggesting a broader association with motor conditions rather than a unique link to Parkinson's.
