Brief summary

We will evaluate whether a course of cognitive training can reduce symptoms of FOG in PD. This study will randomize patients into either a 7-week program of cognitive training or a sham control condition. Treatment response will be assessed by video recordings of specific walking tasks (TUG), taken before and after training. In addition, functional brain imaging whilst patients perform a validated virtual reality gait paradigm will be used to determine the brain activation patterns associated with improvements in FOG.

This project will hopefully identify an effective novel treatment for FOG that does not involve pharmacological or surgical intervention. The use of brain imaging will also allow us to see why patients might have differential responses to therapy. Identifying the nature of these relationships will hopefully advance our understanding of freezing and lead to new directions for targeting therapy.


Key inclusion criteria

This study will recruit 100 PD patients with a clinical history of FOG. We aim to recruit participants based on information obtained from medical assessments (including subjective report of symptoms and Mini Mental State Examination (MMSE) score of 24 or greater) as well as self-report measures of freezing (e.g. a positive score on question 3 of the FOG Questionnaire) completed at the PD Research Clinic located at the Brain and Mind Centre.
