Background and Purpose: The aim of this study was to determine the inc
idence, type, and prognosis of stroke in young adults in Cantabria, Sp
ain. Methods: We investigated prospectively all patients aged 50 years
or below who were admitted with the diagnosis of a stroke to the Univ
ersity Hospital ''Marquis de Valdecilla'' from April 1, 1986, to March
31, 1988. This is the main hospital of the region to which all patien
ts with neurological problems are referred. These patients underwent a
complete clinical and laboratory assessment for stroke and had 1-year
mean follow-up. Results: The total series included 81 patients. The a
nnual age-specific crude incidence rates of stroke were 17.3 and 10.4
per 100,000 for males and females, respectively. Twenty-four patients
(30%) were diagnosed as having nonembolic cerebral infarction, 14 (17%
) embolic cerebral infarction, 20 (25%) subarachnoid hemorrhage, 22 (2
7%) spontaneous cerebral hemorrhage, and one case (1%) cerebral venous
thrombosis. Eighteen patients (22%) died within 30 days of the cerebr
ovascular event, and two others died during the follow-up period. Seve
nty-nine percent of the survivors recovered and were completely self-s
ufficient. Conclusions: The incidence of stroke in the young found in
Cantabria is comparable with that in previous studies. The initial hos
pital mortality was not negligible, but the prognosis among the surviv
ors was favorable.
