Machado-Joseph Disease (MJD) or spinocerebellar ataxia type 3 (SCA3) is the most common spinocerebellar ataxia worldwide. MJD shows remarked clinical heterogeneity and presents with various clinical manifestations, including cerebellar ataxia, limb incoordination, dysarthria, sleep disorders, axonal neuropathy, dystonia, pyramidal signs and, diplopia. No effective treatment is currently available for MJD.~Repetitive transcranial magnetic stimulation (rTMS)enables non-invasive modulation of cortical excitability. rTMS targeting cerebellar structures is capable of inducing long-lasting changes in the excitability of cerebello-thalamocortical pathways.~Subjects will be randomized in two groups, one receiving a consecutive 15-day treatment with 1 Hz of repetitive transcranial magnetic stimulation and the other receiving sham stimulation with identical parameters. Patients will be clinically assessed at baseline, during intervention period at 7 days and 15 days immediate after treatment.
Machado-Joseph Disease (MJD) or spinocerebellar ataxia type 3 (SCA3) is the most common spinocerebellar ataxia worldwide.Repetitive transcranial magnetic stimulation (rTMS) is a form of brain stimulation therapy used to treat depression and cerebellar ataxias. In this randomized, double-blind, sham-controlled study, the investigators will evaluate whether a 15 day treatment with 1 Hz of repetitive transcranial magnetic stimulation (rTMS) can improve symptoms (motor symptoms and non-motor symptoms) in patients with MJD.
