Several authors have recently reported a broad cognitive impairment in autosomal dominant cerebellar ataxias (ADCAs) patients. However, only a few studies on neuropsychological features in spinocerebellar ataxia type 2 (SCA2) patients are present in the current literature. The aim of this study is to evaluate the cognitive impairment in a wide sample of(More)
Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant neurodegenerative disorder mapped on chromosome 12. Different results have been reported in spinocerebellar ataxias following transcranial magnetic stimulation (TMS). TMS-induced cortical silent period (CSP) was prolonged in different cerebellar disorders. Here we evaluate the duration of the(More)
The aim of this study was to evaluate motor cortex excitability in spinocerebellar ataxia type 2 (SCA2). Cortical silent period (CSP), motor thresholds, and intracortical inhibition and facilitation by paired transcranial magnetic stimulation (TMS) were investigated in 18 SCA2 patients and in 20 controls. The mean CSP duration and motor threshold after TMS(More)
The aim of this study is to verify, after recovery, the presence of specific patterns of cognitive dysfunctions in Transient Global Amnesia (TGA). Fourteen patients with the diagnosis of TGA were submitted to a battery of neuropsychological tests and compared to a matched control group. We found significant qualitative and quantitative differences between(More)
INTRODUCTION Celiac disease (CD) may initially present as a neurological disorder or may be complicated by neurological changes. To date, neurophysiological studies aiming to an objective evaluation of the potential central nervous system involvement in CD are lacking. OBJECTIVE To assess the profile of cortical excitability to Transcranial Magnetic(More)
INTRODUCTION An imbalance between excitatory and inhibitory synaptic excitability was observed in de novo patients with celiac disease (CD) in a previous study with Transcranial Magnetic Stimulation (TMS), suggesting a subclinical involvement of GABAergic and glutamatergic neurotransmission in asymptomatic patients. The aim of this investigation was to(More)
Structural corpus callosum (CC) changes in patients with leukoaraiosis (LA) are significantly associated with cognitive and motor impairment. The aim of this study is to investigate the transcallosal fibers functioning by means of transcranial magnetic stimulation (TMS) in elderly patients with LA. The resting motor threshold (rMT), the motor-evoked(More)
