Freezing of gait (FOG) is a poorly understood symptom of Parkinson’s disease (PD) during which a patient suffers an abrupt cessation of walking [1]. Whilst little consensus exists regarding the mechanisms underlying FOG [2], there is considerable evidence that additional cognitive demand whilst walking represents a significant trigger in the pathophysiology of FOG [2]. In addition, the severity of self-reported FOG has been correlated with a selective deficit in attentional set-shifting [3… CONTINUE READING
