Ideally, any neurologic deficits should be recorded with the aid of a formal and reproducible stroke scale, such as the National Institutes of Health Stroke Scale (NIHSS) (For additional information on this systematic assessment tool, see Stroke Scale). A stroke scale prompts the examiner to be thorough and allows different examiners to repeat the examination reliably during subsequent phases of the evaluation. Any neurologic abnormalities should suggest the diagnosis of stroke (or ongoing neurologic event) rather than TIA.
