Final answer:
True, symptoms of a TIA usually last less than about 5 minutes. A transient ischemic attack (TIA) involves a temporary loss of neurological function, resolving often within minutes, though it can last up to 24 hours. Prompt recognition and treatment of a TIA are crucial for recovery and prevention of future strokes.
Step-by-step explanation:
The statement 'symptoms of a TIA will usually last less than about 5 minutes' is generally true. A transient ischemic attack (TIA), often referred to as a 'mini-stroke,' is characterized by a temporary loss of neurological function due to a brief interruption in blood flow to the brain. These symptoms can arise suddenly but typically resolve quickly, sometimes within minutes, although they can last up to 24 hours. Unlike a stroke, the effects of a TIA are temporary, and there is no cell death. However, experiencing a TIA is a warning sign that a person is at increased risk for a full-blown stroke in the future. Recognizing a TIA is crucial, and the FAST mnemonic for Face drooping, Arm weakness, Speech difficulties, and Time to call emergency services is a valuable tool for early identification and prompt treatment.
Recovery from a TIA is strongly dependent on the speed of treatment. Symptoms may include difficulty with moving or feeling on one side of the body, problems with speech or understanding, confusion, and sometimes dizziness. If someone experiences these symptoms swiftly and they dissipate on their own within an hour or two, it's classified as a TIA.
