66% de los pacientes tuvieron un desencadenante identificable. La mediana del tiempo transcurrido entre el inicio de los síntomas y la visita a la sala de emergencia fue de 2 horas, con una duración promedio del episodio de 4 horas. La edad promedio de presentación fue de 65 años (20-84) 52% mujeres. Se comparó el grupo de AGT recurrente versus episodio único, aplicando un modelo de regresión logística multivariada. Métodos:Īnálisis retrospectivo de una cohorte de 203 pacientes con AGT de un único centro en Buenos Aires, Argentina, diagnosticados entre enero-2011 y marzo-2017 Se analizaron las características clínicas y los estudios complementarios (laboratorio, Doppler de vena yugular y RM encéfalo). Nuestro objetivo fue buscar predictores de recurrencia en pacientes con AGT. Although the complementary studies allowed us to guide the diagnosis, they did not appear to have a significant impact on the prediction of recurrence risk.Īmnesia, anterograde recurrence amnesia, transient globalĮl riesgo de recurrencia de nuevos eventos de amnesia en pacientes que han experimentado previamente Amnesia Global Transitoria (AGT) oscila entre el 2.9-23.8%. None of the other clinical characteristics evaluated allowed us to predict an increased risk of recurrence. Patients with migraine may have a higher risk of recurrent TGA. None of the other clinical characteristics and complementary studies were predictors of increased risk of recurrence. Patients with recurrent TGA had a more frequent history of migraine than patients without recurrence (37.5% vs. Eight percent of patients had TGA recurrence. Jugular reflux was present in 66% of patients and 22% showed images with hippocampus restriction on diffusion-weighted MRI. Sixty-six percent of patients referred to an identifiable trigger. Median time elapsed between symptom onset and ER visit was two hours, with the average episode duration lasting four hours. Mean age at presentation was 65 years (20-84) 52% were female. Comparison between patients with recurrent versus single episode TGA was performed, applying a multivariate logistic regression model. Retrospective analysis to identify recurrence predictors in a cohort of 203 TGA patients from a single center in Buenos Aires, Argentina, diagnosed between January 2011 and March 2017 Clinical features and complementary studies (laboratory results, jugular vein Doppler ultrasound and brain MRI) were analyzed. Our objective was to search for recurrence predictors in TGA patients. The risk of recurrence of new amnesia events in patients having previously experienced transient global amnesia (TGA) ranges between 2.9-23.8%.
