Motor Disorders

Resources for Patients and Caregivers

Motor disorders are malfunctions of the nervous system that cause involuntary or uncontrollable movements or actions of the body. These disorders can cause lack of intended movement or an excess of involuntary movement.

  • Negative symptoms in Huntington's disease
    by Paola Soliveri on January 24, 2022

    CONCLUSIONS: Negative symptoms are pervasive in HD but more severe in stage 2. The associations of SANS with MMSE and SAPS suggest impaired cognition and thinking as important in generating negative symptoms. SANS appears useful for revealing a wide range of negative symptoms in HD.

  • Effects of Framingham 10-year cardiovascular risk score and viral load on brain integrity in persons with HIV
    by Michelle Glans on January 24, 2022

    CONCLUSIONS: Neuroimaging but not cognitive measures were associated with elevated cardiovascular risk. HIV serostatus was associated with diminished brain volumes and worse cognition while CBF remained unchanged, reflecting potential protective effects of cART. Neuroimaging measures of structure (volume) and function (CBF) may identify contributions of comorbidities, but future longitudinal studies are needed.

  • Cortical correlates of gait compensation strategies in Parkinson's disease
    by Anouk Tosserams on January 24, 2022

    OBJECTIVE: Gait impairment in persons with Parkinson's disease is common and debilitating. Compensation strategies (e.g. external cues) are an essential part of rehabilitation, but their underlying mechanisms remain unclear. Using EEG, we explored the cortical correlates of three categories of strategies: external cueing, internal cueing, and action observation.

  • Real-Life Turning Movements Capture Subtle Longitudinal and Preataxic Changes in Cerebellar Ataxia
    by Annika Thierfelder on January 24, 2022

    CONCLUSIONS: Measures of turning allow capturing specific changes of dynamic balance in degenerative ataxia in real life, with high sensitivity to longitudinal differences in ataxia severity and to the preataxic stage. They thus present promising ecologically valid motor biomarkers, even in the highly treatment-relevant early stages of degenerative cerebellar disease. © 2022 The Authors.
