Prognóstico de acidentes neurológicos transitórios com sintomas atípicos
| Resumo: | Introduction: There is a significant percentage of transient neurological attacks that doesn’t present the typical characteristics of transient ischemic attacks (TIA) and doesn’t fulfill the diagnostic criteria of other non-vascular diseases. Methods: Prospective study of patients with atypical symptoms followed in TIA clinic between 2004 and 2010. Three types of symptoms were selected for this study: isolated dysarthria, isolated diplopia and isolated sensory deficit with progressive onset. Results: In a total of 603 patients with transient neurologic symptoms (<24 hours) referred to the TIA clinic, there were 166 patients to whom a diagnosis could not be assigned. Of these, seven presented isolated dysarthria, four presented isolated diplopia and 14 presented isolated sensory deficit with progressive onset. With an average follow-up of 590 days, only one patient, from the isolated dysarthria group, had a vascular recurrence. This patient had however vascular risk factors and a non-acute ischemic lesion on head CT at the time she presented with isolated dysarthria. Conclusions: Although the sample in this study is small, vascular events did not occur during follow-up, particularly in patients with isolated diplopia and isolated sensory deficit with progressive onset. These results need to be confirmed in large samples of patients with such types of atypical transient neurological attacks. |
