Incidence and short-term outcome of cerebral infarction in young adults in western Norway.
ABSTRACT We sought to determine the incidence and short-term outcome of people aged 15 to 49 years with first-ever cerebral infarction in 1988-1997 in Hordaland County, Norway.
Cases were found from computer search of hospital registries and detailed review of patient records. Stroke subtype was classified according to the major intracranial artery affected. Short-term outcome was evaluated by the modified Rankin Scale (mRS).
A total of 96 women and 136 men met the inclusion criteria. The average annual incidence was 11.4/100 000. Women outnumbered men among those aged <30 years (P=0.059); men predominated among those aged > or =30 years (P=0.004). A total of 148 patients had anterior circulation infarction (64%), and 84 had posterior circulation infarction (36%) (P<0.001). Patients with posterior circulation infarction had better mRS score at discharge (P=0.005). Eighty percent had favorable outcome (mRS score < or =2). The 30-day case fatality rate was 3.4%. The recurrence rate in hospital was 2.2%.
The incidence was in the lower range compared with other reports from western Europe. Although men predominated, there was a strong trend toward more women among patients aged <30 years. Short-term outcome was generally good. Patients with posterior circulation infarction had significantly better short-term outcome.

ABSTRACT: Introduction. Young adults are likely to differ from old patients concerning cerebral infarction. Methods. We compared characteristics of patients aged under and above 50 years, admitted to the Department of Neurology with cerebral infarction between 2006 and 2009, based on prospective registration. Investigation followed one common protocol for both groups. Results and Discussion. One hundred patients (8.2%) were <50 years old, and the proportion of males was higher in this group (72% versus 55.8%, P = .002). Young stroke patients are more often current smokers (44.1% versus 23.6%, P < .001). Common causes for stroke in the young were cervical artery dissection (18% versus 0.6%, P < .001) and cardiac embolism due to disorders other than atrial arrhythmias (18% versus 5.5%, P < .001). Among the old, atrial fibrillation and flutter dominated (29.1% versus 5%, P < .001). Stroke severity and location did not differ. Old patients more often suffered from pneumonia (10.6% versus 2%, P < .003) and urinary tract infection (14.6% versus 2%, P = .001). Conclusions. Males dominate, and current smoking is more common in the young. Cervical artery dissection and nonarrhythmic heart disorders are frequent causes among young patients, while traditional risk factors dominate the old. Stroke severity is similar, but old patients seem more exposed for infectious complications.Stroke research and treatment. 01/2011; 2011:183256.

ABSTRACT: To assess the frequency of females and males aged ≤ 30 years with cerebral infarction in two different time periods. All patients aged ≤ 30 years with arterial cerebral infarction in 1988-1997 and 2006-2010 admitted to Haukeland University Hospital in Bergen, Norway, were included. Risk factors and etiology were assessed. Between 1988 and 1997, 16 females and 7 males had cerebral infarction, whereas 0 females and 13 males had cerebral infarction in 2006-2010 (P = 0.0001). The incidence of cerebral infarction in females was significantly lower between 2006 and 2010 than between 1988 and 1997 (P = 0.007). Our findings suggest that the frequency of cerebral infarction among young females has dropped significantly during recent years.Vascular Health and Risk Management 01/2011; 7:81-4.
