MULTIPLE-SCLEROSIS IN SCANDINAVIA AND FINLAND

Review of studies of incidence of MS over several decades in seven geo graphical areas scattered over Scandinavia and Finland have shown that incidence rates fluctuate significantly with time in most of the area s but in an inconsistent pattern. The incidence appeared to the lowest in the northernmost parts of Norway indicating that the well-known no rth-south gradient for risk of MS does not hold true for high latitude s.
