MRI showed complete reversal of abnormalities in two patients and improvement in one. One patient showed no change from baseline to last follow-up. All eight patients who showed an initial period of continued demyelination stabilised and remained unchanged thereafter. Motor function remained normal or improved after bone-marrow transplantation in ten patients. Verbal intelligence remained within the normal range for 11 patients. Performance (non-verbal) abilities were improved or were stable in seven patients. Decline in performance abilities followed by stability occurred in five patients. Plasma VLCFA concentrations decreased by 55% and remained slightly above the upper limits of normal. 5-10-year follow-up of 12 patients with childhood-onset cerebral X-linked adrenoleukodystrophy shows the long-term beneficial effect of bone marrow transplantation when the procedure is done at an early stage of the disease. |
