Psychomotor speed, a fundamental component of cognitive function, refers to the time it takes to process information and initiate a motor response. This seemingly simple process is, in reality, a highly complex function involving multiple interconnected neural pathways, including sensory perception, cognitive processing, motor planning, and execution. The intricate coordination of these systems is primarily mediated by the fronto-striatal circuits, the cerebellum, and the association cortices. Consequently, a decline in psychomotor speed is a sensitive and early indicator of neurological dysfunction. This article provides an overview of the assessment of psychomotor speed in various neurological disorders and diseases, highlighting the utility of specific neuropsychological tests as diagnostic and prognostic tools [1].
