NEUROAXONAL DYSTROPHY IN CHILDHOOD Report of Two Second Cousins with Hallerworden‐Spatz Disease, and a Case of Seitelberger's Disease

Abstract
Three late infantile cases of neuroaxonal dystrophy are presented, two of them second cousins with Hallerworden‐Spatz disease and one sporadic case with Seitelberger's disease. At about 1 1/2 years of age the patients with Hallerworden‐Spatz disease developed clinical signs including progressive extrapyramidal motor disorder and mental retardation. They died at 8 and 11 years. Iron deposits and axonal dystrophy were found in the pallidum. The changes are compared to those in a case of infantile neuroaxonal dystrophy (Seitelberger's disease), the first to be reported in Scandinavia.
