## TL;DR

This study examines how Brazilian physicians diagnose and manage transient ischemic attacks, revealing inconsistent practices and a need for better guidelines.

## Contribution

The study identifies variability in TIA management practices among Brazilian physicians and emphasizes the need for standardized protocols.

## Key findings

- There is significant variability in hospital admission and diagnostic testing for TIA among Brazilian physicians.
- Many physicians use risk stratification tools but do not consistently follow recommended guidelines for imaging or medication.
- The study suggests that improved education and standardized protocols could reduce stroke recurrence rates.

## Abstract

Transient ischemic attack (TIA) is a critical vascular event that often precedes strokes. Despite its significance, management varies widely across physicians.

To evaluate the knowledge and practices of Brazilian physicians regarding TIA diagnosis and management.

A survey was conducted among members of the Brazilian Academy of Neurology. It included questions about demographic information, TIA management practices, and knowledge of guidelines.

While most respondents were neurologists or residents, there was significant variability in hospital admission, diagnostic testing, and treatment strategies. Many physicians relied on risk stratification tools but did not consistently follow guidelines for diagnostic imaging or medication.

These findings highlight the need for improved education and standardized protocols for TIA management in Brazil. Implementing public health policies to address these gaps could significantly reduce stroke recurrence rates and improve patient outcomes.
