Which of the following is a key characteristic of a TIA?

A key characteristic of a Transient Ischemic Attack (TIA) is that it causes temporary neurological symptoms which fully resolve within 24 hours. The term 'transient' indicates that the neurological deficits are not permanent and typically last for a much shorter duration, often just a few minutes to hours, but never exceeding 24 hours. This temporary nature of symptoms helps distinguish a TIA from a stroke, which results in lasting damage or irreversible brain injury due to prolonged disruption of blood supply. The full recovery aspect within that 24-hour timeframe is crucial, as it signals that there is no permanent damage to the brain, which aligns precisely with the definition of a TIA.
