Motor neuron disease in blacks. Epidemiological observations in Natal.
A series of 86 black, Indian and white patients with motor neuron disease were analysed retrospectively. Although the material does not allow statistically valid conclusions, there are sufficient cases among blacks to allow two prima facie observations in this population group: (i) motor neuron disease has an earlier age of onset than in whites and Indians; and (ii) more patients come from peripheral and rural areas than would be expected in prevailing circumstances.
