    The study investigated cognitive function in Chinese patients with isolated generalized dystonia (GD) compared to healthy controls.

  • 2

    GD patients exhibited mild cognitive impairments, particularly in executive function, attention, and episodic memory.

  • 3

    No significant associations were found between cognitive performance and motor severity, disease duration, or medication use.

  • 4

    The study included 20 GD patients and matched healthy controls, utilizing standardized rating scales and a neuropsychological battery.

  • 5

    Cognitive performance differences were largely independent of disease etiology, with only a subset of deficits remaining significant after adjustment.
