title: Monthly distribution of multiple sclerosis patients' births.
abstract: As part of an integrated geographical and environmental epidemiological study of multiple sclerosis (MS) in Budapest's Pesterzsébet district, many biometeorological variables were specifically examined. Also, the monthly distribution of birthdates of MS patients resident in the district was plotted. Patients reliably diagnosed with MS were found to have been born in greater numbers in the months of April and October, precisely 6 months apart. This finding indicates the presence of natural non-genetic factors in the creation of MS susceptibility, affecting the nervous system at the crucial time of myelination.
