This study’s objective is to identify which characteristics of persons with the condition of Multiple Sclerosis (MS) and a first order relative can predict its occurrence. A questionnaire and logistics regression was used to develop a prediction model for the probability of having MS condition. Six models were developed using eight important predictors: age, mother, sister or daughter having MS condition, persons’ fibromialgy, sister allergy, sons’ sinus, and age person got chicken pox. Female relatives with MS reduce the odds of the person having MS condition to 1:6221 (daughter), to 1:50 (sister) for one model, and sisters’ allergy to 1:4.3. Sons’ sinus odds is 8:1 and persons’ fibromialgy odds of MS is 1:53, even though these three had no medical explanation; gender having women get MS 2.4:1 vs. men. Plots were developed to compare false positives and false negatives in predicting the condition of MS, and borderline cases.
