Cognitive–motor Interference in Individuals With a Neurologic Disorder: A Systematic Review of Neural Correlates

Background: Performing a cognitive task and motor simultaneously is an everyday act that can lead to decreased performance on both tasks. Objective: To provide insight into the neural correlates associated with cognitive–motor dual tasking in individuals neurologic disorder. Method: We searched PubMed Web of Science databases for studies had been published up January 16th, 2019. Studies investigating variety disorders were included, independently from whether study included healthy controls. Clinical imaging data abstracted comparison between single tasks disorder controls Results: Eighteen met inclusion criteria. Study populations Parkinson disease, multiple sclerosis, mild impairment, Alzheimer traumatic brain injury, stroke. Neuroimaging types used during upper limb or gait fMRI, functional near-infrared spectroscopy, EEG, PET. Conclusion: Despite large heterogeneity methodologies, some recurrent patterns noted. Particularly, patients, already higher activation was seen compared controls, perhaps compromising patients’ ability further adapt increasing load resulting reduced behavioral performance.
