چکیده

Magnetic resonance imaging of a girl with giant axonal neuropathy revealed a progressive white matter disease. In close agreement with histopathological features reported previously, localized proton magnetic resonance spectroscopy at 9 and 12 years of age indicated a specific damage or loss of axons (reduced N-acetylaspartate and N-acetylaspartylglutamate) accompanied by acute demyelination (elevated choline-containing compounds, myo-inositol, and lactate) in white matter as well as a generalized proliferation of glial cells (elevated choline-containing compounds and myo-inositol) in both gray and white matter.

Spectrum of magnetic resonance imaging findings in a family with giant axonal neuropathy confirmed by genetic studies.

Giant axonal neuropathy (GAN) is a disorder that affects both the peripheral and central nervous system with clinical and genetic heterogeneity. We describe the spectrum of magnetic resonance imaging (MRI), MR-spectroscopy (MRS), and diffusion changes in two siblings from India. In addition to the described MRI findings two unreported findings, hyperintensity signals of both the globus pallidus...

Magnetic resonance spectroscopy of normal appearing white matter in early relapsing-remitting multiple sclerosis: correlations between disability and spectroscopy

BACKGROUND What currently appears to be irreversible axonal loss in normal appearing white matter, measured by proton magnetic resonance spectroscopy is of great interest in the study of Multiple Sclerosis. Our aim is to determine the axonal damage in normal appearing white matter measured by magnetic resonance spectroscopy and to correlate this with the functional disability measured by Multip...

Axonal injury in the internal capsule correlates with motor impairment after stroke.

Background and Purpose--Magnetic resonance spectroscopy (MRS) in ischemic stroke has shown a correlation between N-acetylaspartate (NAA) loss from the infarcted region and disability. We tested the hypothesis that NAA loss in the descending motor pathways, measured at the level of the posterior limb of the internal capsule, would determine motor deficit after a cortical, subcortical, or striato...

Patients lacking the major CNS myelin protein, proteolipid protein 1, develop length-dependent axonal degeneration in the absence of demyelination and inflammation.

Axonal degeneration contributes to clinical disability in the acquired demyelinating disease multiple sclerosis. Axonal degeneration occurs during acute attacks, associated with inflammation, and during the chronic progressive phase of the disease in which inflammation is not prominent. To explore the importance of interactions between oligodendrocytes and axons in the CNS, we analysed the brai...

Giant axonal neuropathy: observations on a further patient.

A further child with giant axonal neuropathy (GAN), abnormally curly hair and consanguineous parents is described. Of the 19 patients with GAN so far reported in the literature, six, including the present patient, have resulted from consanguineous marriages. This makes autosomal recessive inheritance of GAN highly probable. Our patient also exhibited cerebellar ataxia and signs of pyramidal tra...
