In an incomplete study, the Government Medical Education National Advisory Committee in 1980 suggested that there would be an oversupply of neurologists by 1990. A subsequent Advisory Committee undertook an in-depth evaluation, concluding that neurology would be in near balance by 1990. Several factors that were not used by the Advisory Committee could alter these conclusions, depending on the weight given to these factors separately or collectively. We do not have enough evidence to justify any action now to control the growth of neurology.
