Complex movement disorders at disease onset in childhood narcolepsy with cataplexy
Narcolepsy with cataplexy is characterized by daytime sleepiness, cataplexy (sudden loss of bilateral muscle tone triggered by emotions), sleep paralysis, hypnagogic hallucinations and disturbed nocturnal sleep. Narcolepsy with cataplexy is most often associated with human leucocyte antigen-DQB1*0602 and is caused by the loss of hypocretin-producing neurons in the hypothalamus of likely autoimm...
متن کاملAdult onset spinocerebellar ataxia in a Canadian movement disorders clinic.
BACKGROUND The spinocerebellar ataxias (SCAs) are a genetically and clinically heterogeneous group of neurodegenerative disorders. Relative frequencies vary within different ethnic groups and geographical locations. OBJECTIVES 1) To determine the frequencies of hereditary and sporadic adult onset SCAs in the Movement Disorders population; 2) to assess if the fragile X mental retardation gene ...
متن کاملDo Disorders of Movement Cause Movement Disorders and Dementia?
Neurons require long-distance microtubule-based transport systems to ferry vital cellular cargoes and signals between cell bodies and axonal or dendritic terminals. Considerable progress has been made on developing a molecular understanding of these processes and how they are integrated into normal neuronal functions. Recent work also suggests that these transport systems may fail early in the ...
متن کاملSpatio-Temporal Patterning in Primary Motor Cortex at Movement Onset.
Voluntary movement initiation involves the engagement of large populations of motor cortical neurons around movement onset. Despite knowledge of the temporal dynamics that lead to movement, the spatial structure of these dynamics across the cortical surface remains unknown. In data from 4 rhesus macaques, we show that the timing of attenuation of beta frequency local field potential oscillation...
متن کاملMovement Disorders –
TAKE HOME MESSAGES 1. Movement disorders involve the basal ganglia and associated structures, often affecting the globus pallidus (the output target of the striatum) 2. Abnormal involuntary movements are classified as hypokinetic or hyperkinetic, and are subclassified byspeed, duration and whether or not they are rhythmic. 3. Parkinsonism is characterized by the presence of at least 2 of the 4 ...
