Brain magnetic resonance imaging findings in acute relapses of neuromyelitis optica spectrum disorders.

We studied cranial magnetic resonance imaging (MRI) lesions in three women with acute attacks of recurrent longitudinally extensive transverse myelitis (r-LETM), recurrent-optic neuritis (r-ON) and r-LETM-CNS. Neuromyelitis Optica -immunoglobulin (IgG) antibody was positive in all cases. Brain MRI (1.

[Corticospinal dysfunction in patients with primary and amyotrophic lateral sclerosis].

Introduction: Corticoespinal dysfunction is a common finding in primary and amyotrophic lateral sclerosis (PLS and ALS). AIM. To compare the behaviour of motor evoked potentials (MEP) with transcranial magnetic stimulation (TMS) in patients with ALS and PLS.

[Brainstem lesions: clinicoradiological electrophysiological correlation when chronic].

Introduction: The brainstem is a vital structure. Imaging and electrophysiological studies are important aids to clinical diagnosis.

Objective: To define the clinical, imaging and electrophysiological correlation in 28 patients with chronic brainstem lesions.
