Cerebrovascular disease in Scotland during 1959 to 1983: its geographical distribution and associations.

A study of the geographical distribution of cerebrovascular disease in Scottish communities during three quinquennia between 1959 and 1983 showed a marked tendency for high SMRs to be present in the west of Scotland and low SMRs in the east. Cerebrovascular disease was significantly correlated with coronary heart disease, with bronchitis, emphysema and asthma, and to a lesser extent with other heart disease, with other circulatory disease and with indices of overcrowding. It was not associated with either urbanization or industrialization.
