Leigh Syndrome

in Leigh syndrome (Fig. 3.8) and the pattern of thiamine deficiency (Fig. 3.9) are very similar, although the lesions in the mamillary bodies, typical for thiamine deficiency, are consistently lacking in Leigh syndrome, but most different causes of energy failure lead to very different patterns of abnormalities (Figs. 3.1,3.2,3.4-3.13). The biochemical explanation for the differences in selectively involved structures is unclear, and apparently our present models are too simplistic.

Apart from mitochondrially mediated disorders, other conditions may involve the basal ganglia predominantly or selectively. This is the case in many inborn errors of metabolism other than mitochon-driopathies, in hepatic failure (Fig. 3.14), and in classic Creutzfeldt-Jakob disease (Fig. 3.15). The explanations must be different from those so far proposed.

In glutaric aciduria type I there is typically involvement of the putamen and caudate nucleus, but not of the cortical layers and Purkinje cells. The neo-

Fig. 3.10. Typical involvement of the parieto-occipital region in a neonate with hypoglycemia; in the worst cases this leads to multicystic encephalopathy restricted to this region. Selective vulnerability of this region for hypoglycemia disappears with age, indicating the influence of morphologic and biochemical maturation of the brain on the pattern of resulting damage
