The dopaminergic response in multiple system atrophy.
Fifteen of 23 pathologically confirmed cases of multiple system atrophy (MSA) showed some initial response to levodopa and eight of these remained at least partially responsive at the time of death. Eleven developed motor oscillations, and drug-induced dyskinesias, often involving the face and jaw, were also seen in 11 cases. Acute levodopa and apomorphine challenges were administered to 11 pat...
متن کاملDifferences in Dopaminergic Modulation to Motor Cortical Plasticity between Parkinson's Disease and Multiple System Atrophy
Dopamine modulates the synaptic plasticity in the primary motor cortex (M1). To evaluate whether the functioning of the cortico-striatal circuit is necessary for this modulation, we applied a paired associative stimulation (PAS) protocol that comprised an electric stimulus to the right median nerve at the wrist and subsequent transcranial magnetic stimulation of the left M1, to 10 patients with...
متن کاملMultiple system atrophy.
Multiple system atrophy (MSA) is an adult-onset sporadic progressive neurodegenerative disorder of unknown etiology. It is clinically characterized by the variable combination of autonomic failure, parkinsonism, cerebellar ataxia, and pyramidal signs. The present review summarizes up-to-date knowledge on the clinical diagnosis and molecular pathology of MSA. We also review the role of additiona...
متن کاملMultiple system atrophy.
Multiple system atrophy is a neurological disorder that has gone unrecognized for too long due to its involvement across multiple regions of the central nervous system. This disorder is finally being unveiled through increased reporting in the scientific literature. Further research will enhance our understanding of this disease and lead to more effective treatment regimens as well as an improv...
متن کاملDystonia in multiple system atrophy.
OBJECTIVE To delineate the frequency and nature of dystonia in multiple system atrophy (MSA). METHODS A cohort of 24 patients with clinically probable MSA over the past 10 years were prospectively followed up. Motor features were either dominated by parkinsonism (MSA-P subtype, n=18) or cerebellar ataxia (MSA-C, n=6). Classification of dystonic features and their changes with time was based o...
