Impaired sense of agency in functional movement disorders: An fMRI study
The sense of agency (SA) is an established framework that refers to our ability to exert and perceive control over our own actions. Having an intact SA provides the basis for the human perception of voluntariness, while impairments in SA are hypothesized to lead to the perception of movements being involuntary that may be seen many neurological or psychiatric disorders. Individuals with functio...
متن کاملFunctional neuroanatomy and physiology in movement disorders
Introduction The most common movement disorders, including Parkinson’s disease (PD), Huntington’s disease (HD), dystonia, and dyskinesias are associated with pathology within the basal ganglia (BG), a group of graymatter structures situated at the base of the forebrain that are extensively interconnected together as well as with different parts of the cerebral cortex, the thalamus, and other su...
متن کاملImpaired movement timing in neurological disorders: rehabilitation and treatment strategies.
Timing abnormalities have been reported in many neurological disorders, including Parkinson's disease (PD). In PD, motor-timing impairments are especially debilitating in gait. Despite impaired audiomotor synchronization, PD patients' gait improves when they walk with an auditory metronome or with music. Building on that research, we make recommendations for optimizing sensory cues to improve t...
متن کاملImpaired visual size-discrimination in children with movement disorders
Multisensory integration of spatial information occurs late in childhood, at around eight years (Gori, Del Viva, Sandini, & Burr, 2008). For younger children, the haptic system dominates size discrimination and vision dominates orientation discrimination: the dominance may reflect sensory calibration, and could have direct consequences on children born with specific sensory disabilities. Here w...
متن کاملImpaired awareness of movement disorders in Parkinson's disease.
BACKGROUND This study analyzed the presence of awareness of movement disorders (dyskinesias and hypokinesias) in 25 patients with Parkinson's disease (PD) and motor fluctuations (dyskinesias, wearing off, on-off fluctuations). Of the few studies that have dealt with this topic, none have analyzed the differences in the awareness of motor deficits by comparing the on and off states using motor s...
