Stroke Symptoms Require Immediate Evaluation Even If They Go Away Within an Hour


eMediNexus    21 February 2023

According to a study published in the journal Stroke, transient ischemic attack (TIA) symptoms, which vanish within an hour of onset, require immediate evaluation in order to help avert a full-blown stroke. A transient ischemic attack (TIA) is defined as a temporary blockage of blood flow to the brain. According to one study cited in the statement, 43 percent of people who had an ischemic stroke had a TIA the week before their stroke.


The statement published by the American Heart Association offered a standardized approach to evaluating people with suspected TIA, along with directives for hospitals in rural areas that may not have access to advanced imaging or an on-site neurologist. Any delay in evaluation might be caused by geographical considerations, a lack of resources at hospitals, or differences in the comfort level and level of experience among medical experts. For instance, a TIA patient may not get the same evaluation in an emergency room with limited resources compared to a certified stroke center.


Hence, the researchers pointed out that these new statements were written with emergency rooms with limited facilities and physicians or internists in mind. The statement also offered tips to help medical personnel distinguish between a TIA and a "TIA mimic," a disorder that exhibits some TIA-like symptoms but is actually caused by another illness such as low blood sugar, a seizure, or a migraine.


Blood tests should be performed in the ER to rule out other illnesses that could manifest similarly to a TIA, such as low blood sugar or an infection, and to screen for cardiovascular risk factors, including diabetes and high cholesterol. Given the elevated risk of stroke in the days after a TIA, the statement advised that the patient should follow up with a neurologist as soon as possible, ideally within 48 hours but no later than one week if consultation is not feasible during the emergency visit.
