Which gait-related apraxia is commonly seen with normal pressure hydrocephalus?

Gait disturbance in normal pressure hydrocephalus is best understood as gait apraxia—a problem with planning and initiating walking rather than a failure of muscle strength. The ventricles enlarge and disrupt frontal–subcortical circuits, so patients may have a slow, hesitant, magnetic or shuffling gait with difficulty turning and initiating steps, even though their legs are physically capable. This distinction matters: the issue is motor planning, not primary weakness or coordination problems. In contrast, dressing apraxia arises from parietal dysfunction and presents as trouble dressing, constructional apraxia involves drawing or constructing items, and alien-hand syndrome features involuntary, purposeful movement of a limb due to disconnection in higher-order networks. Thus, the gait-specific impairment seen with normal pressure hydrocephalus is gait apraxia.
