How is a TIA diagnosed?

A transient ischemic attack (TIA) is typically diagnosed clinically through a detailed assessment of the patient's history and a neurological examination. During this evaluation, a healthcare provider looks for symptoms that are characteristic of a TIA, such as sudden numbness, weakness, confusion, or difficulties with speech or vision. These symptoms usually resolve within a short period, typically less than 24 hours.

While imaging techniques such as MRI can be useful in ruling out other conditions and confirming the diagnosis of a TIA, they are not primarily used for the diagnosis itself. In contrast, blood tests and X-ray imaging do not provide relevant information specifically related to the diagnosis of a TIA. The clinical evaluation is essential, as it helps distinguish a TIA from other potential causes of similar symptoms and sets the stage for subsequent management and investigation if needed.
