Abstract:

BACKGROUND: Cerebrovascular accident (CVA) is the third leading cause of death and disability in developed countries. Anyone suspected of having a stroke should be taken immediately to a medical facility for diagnosis and treatment. The symptoms that follow a stroke aren't significant and depend on the area of the brain that has been affected and the amount of tissue damaged. Parameters for predicting long-term outcome in such patients have not been clearly delineated, therefore the aim of this study was to investigate this possibility and to test a system that might practicably be used routinely to aid management and predict outcomes of individual stroke patients.

METHODS: A descriptive hospital-based study of the neurological symptoms and signs of 503 patients with ischemic stroke, including severe headache, seizure, eye movement disorder, pupil size, Glasgow Coma Scale (GCS), agitation were analyzed in this study.

RESULTS: In the current study, dilated pupils, agitation, acute onset headache, lower GCS score, seizure, and eye gaze impairment had significantly higher prevalence in hemorrhagic stroke patients (P<0.001). However, the rate of gradual progressive headache is significantly higher in ischemic stroke patients (P<0.001).

CONCLUSION: Although this result provides reliable indicators for discrimination of stroke types, imaging studies are still the gold standard modality for diagnosis.
