LBSL is diagnosed on the basis of the clinical symptoms in combination with specific MRI and magnetic resonance spectroscopy (MRS) findings . Distinct MRI findings in the form of selective affection of subcortical and deep white matter tracts of the brain (involving the posterior limb of internal capsules and sparing the subcortical U fibers), dorsal column and lateral cortico-spinal tracts of the spinal cord should lead to the diagnosis of LBSL supported by the presence of lactate peak in 1 H MRS. Many GARD web pages are still in development. Neurol India 2010;58 .

Epidemiology Although considered rare, the exact prevalence is unknown. Leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation (LBSL) is defined on the basis of a highly characteristic constellation of abnormalities observed by magnetic resonance imaging and spectroscopy (Scheper et al., 2007).
