Conclusiones: los pacientes con migraña pueden tener un mayor riesgo de recurrencia de AGT. Transient global amnesia (TGA) is an episode of total amnesia that lasts little more than 24 hours. transient epileptic amnesia, typically presents upon waking while TGA does not 6. Ninguna de las otras características clínicas y estudios complementarios fueron predictores de mayor riesgo de recurrencia. Los pacientes con AGT recurrente tuvieron un historial de migraña más frecuente (37.5% vs. 8% de los pacientes presentaron recurrencia. El reflujo yugular estuvo presente en el 66% de los pacientes y el 22% mostró imágenes restrictivas en DWI a nivel hipocampal. 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. Resultados: 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: Análisis 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). Objetivo: Nuestro objetivo fue buscar predictores de recurrencia en pacientes con AGT. RESUMEN El 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%.

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. None of the other clinical characteristics evaluated allowed us to predict an increased risk of recurrence. Conclusions: 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. Results: 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. Methods: 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. Objective: Our objective was to search for recurrence predictors in TGA patients.

Over time, several mechanisms have been proposed for TGA pathogenesis, including venous congestion, cortical spreading depression, seizures and arterial ischaemia. In most cases, there is no activity that triggers a transient global amnesia episode.ABSTRACT The risk of recurrence of new amnesia events in patients having previously experienced transient global amnesia (TGA) ranges between 2.9-23.8%. After more than 50 years since Fisher and Adams’ original description in 1964, 1 transient global amnesia (TGA) is still a puzzling syndrome.

Research suggests there also may be a link between patients who have a history of migraines and those who experience TGA. People older than 50 are more likely to experience TGA. The cause of transient global amnesia is unknown.

Episodes end in 1-8 hours, no more than 24.

Absence of signs suggesting damage to the brain tissue.

Most commonly seen in patients older than 50.

Able to complete complex routine tasks during the episode Transient global amnesia (TGA) is a clinical syndrome characterized by anterograde amnesia, mild retrograde amnesia, and confusion up to 24 hours.

Retaining personal identity during the episode.

Repeatedly asking questions about what is happening.

The main identifiable symptom of transient global amnesia is the sudden, but temporary, loss of short-term memory and not being able to form new memories.
