Multiple Sclerosis Inflammatory disease of the Central Nervous System Insult the myelin of the CNS Unknown causes Probable connection with genetic susceptibility and environmental factors First attempt to connect the disease with the solar activity and space weather
The area of Southwestern Greece Population: 500.000 Sample: 1318 patients Men: 565 Women: 753 Patients/year=120 Patients/month=10
Study based on data from the University Hospital of Patras, covering the area of Southwestern Greece
Seasonal Distribution of MS patients
Months with highest number of patients (admittance peaks)
The annual values of the patients with MS (cases), along with the annual maximum of the solar wind speed (Vsw), the annual number of Halo CMEs, CMEs, intense (X-Type) flares, flares and sunspots (R(z)) 1
Correlation coefficients between the annual values of the solar activity phenomena and the number of patients (Pearson’s product moment correlation coefficient)
Conclusion Rise in admittance rate 6-7 months after an intense geomagnetic storm. Satisfactory correlation coefficient and cross correlation with the Solar Wind speed (77% and 90% respectively). Satisfactory cross correlation with the eruptive phenomena of the Sun: Flares and CME (87% and 88% respectively) with a time lag of 6 and 5 months. Coincide of the three phases of the solar cycle with the three phases of the time series of the admittances although with a different pattern. The two maximums of the time series of the admittance rates appear after a 7 months period from extreme solar events and intense magnetic storms (indicated by the letters δ and θ).
