We systematically investigated the effects of cathodal and anodal Transcranial Direct Current Stimulation (CtDCS, AtDCS) on the electric activity of primary motor cortex during a motor task. High-density electroencephalography was used to define the spatial diffusion of tDCS after effects. Ten healthy subjects performed a finger tapping task with the right(More)
OBJECTIVE To electrophysiologically classify an Italian Guillain-Barré syndrome (GBS) population into demyelinating and axonal subtypes, to investigate how serial recordings changed the classification and to underline the pitfalls in electrodiagnosis of GBS subtypes. METHODS The authors applied two current electrodiagnostic criteria sets for demyelinating(More)
Guillain-Barré syndrome (GBS) is the prototype of a postinfectious autoimmune neuropathy. Molecular mimicry between glycolipid antigens expressed by an infective antigen such as Campylobacter jejuni and the human peripheral nerve has been hypothesized to be the causative mechanism of GBS. However, only 1/1000 of C. jejuni enteritis develops GBS. This(More)
Areflexia is part one of the clinical criteria required to make a diagnosis of Guillain–Barré syndrome (GBS). The diagnostic criteria were stringently developed to exclude non-GBS cases but there have been reports of patients with GBS following Campylobacter jejuni enteritis with normal and exaggerated deep tendon reflexes (DTRs). The aim of this study is(More)
BACKGROUND Whether or not antiganglioside antibodies are related to axonal or demyelinating Guillain-Barré syndrome (GBS) is still a matter of controversy, as detailed in previous studies conducted in Western and Asian countries. OBJECTIVE To clarify whether antiganglioside antibodies are associated with axonal dysfunction in Japanese and Italian GBS(More)
BACKGROUND Acute motor axonal neuropathy (AMAN) and acute motor and sensory axonal neuropathy (AMSAN) are due to an antiganglioside antibody mediated attack, thought to be restricted to motor fibres in AMAN. Sensory symptoms and minor sensory conduction abnormalities, however, have been reported in some AMAN patients. OBJECTIVE To verify whether sensory(More)
Weak cathodal transcranial direct current stimulation (tDCS) of the human hand area modulates corticospinal excitability with a suppression of motor-evoked potentials (MEPs) evoked by transcranial magnetic stimulation (TMS). The changes in excitability persist beyond the time of stimulation if tDCS is given for several minutes and can remain stable for an(More)
Cerebral cavernous malformations (CCMs) are vascular abnormalities that may cause seizures, intracerebral haemorrhages, and focal neurological deficits. Familial form shows an autosomal dominant pattern of inheritance with incomplete penetrance and variable clinical expression. Three genes have been identified causing familial CCM: KRIT1/CCM1, MGC4607/CCM2,(More)
Experimental focal brain ischemia generates in the penumbra recurrent depolarizations which spread across the injured cortex inducing infarct growth. Transcranial direct current stimulation can induce a lasting, polarity-specific, modulation of cortical excitability. To verify whether cathodal transcranial direct current stimulation could reduce the infarct(More)
Some evidences highlighted a higher clinical expression of hereditary neuropathy with liability to pressure palsy (HNPP) in males, and a higher load of traumatic nerve injuries due to different occupational activity has been invoked to explain this observation. It is unknown whether this increased clinical impairment corresponds to a greater(More)
