Determining cognitive processing speed for people with Parkinson’s disease

Takeaway

  • This study found that slowness of information processing (bradyphrenia) in Parkinson’s disease (PD) is mainly associated with an impaired processing speed of the motor and perceptual alertness components analyzed.

Why this matters

    There is no uniform conclusion on whether information processing speed is impaired or not beyond motor performance in people with PD and these findings could inform neurorehabilitation strategies.
