Transcript text: Question 2 of 9 TIAs used to be considered mild events but are now categorized as medical emergencies. What percentage of patients who present with TIA will have a stroke in the future? $5 \%$ to $10 \%$ $10 \%$ to $15 \%$ $20 \%$ to $25 \%$ More than 50\%

Solution

The answer is the first one: $5\%$ to $10\%$.

Explanation for each option:

$5\%$ to $10\%$: This is the correct range. Studies have shown that approximately 5% to 10% of patients who experience a Transient Ischemic Attack (TIA) will have a stroke within the following 90 days, with the highest risk occurring within the first few days after the TIA.
$10\%$ to $15\%$: This range is slightly higher than the generally accepted risk percentage. While some studies might report slightly higher figures, the consensus is that the risk falls within the 5% to 10% range.
$20\%$ to $25\%$: This range is too high compared to the typical risk percentage reported in medical literature for stroke following a TIA.
More than 50%: This is significantly higher than the actual risk. Such a high percentage is not supported by current medical data regarding the risk of stroke after a TIA.

In summary, the risk of having a stroke after a TIA is generally estimated to be between 5% and 10%.
