TIA Assessment Service

The risk of developing a stroke after a hemispheric TIA can be as high as 20% within the first month, with the greatest risk being within the first 72 hours.

Patients first seen in the community with TIA, or with a stroke but having made a good recovery when seen, should be assessed and investigated in a specialist service as soon as possible.

Patients likely to have a diagnosis of TIA should be prescribed an antiplatelet and statin regime immediately.

Patients likely to have a diagnosis of TIA should be advised not to drive until assessed by a specialist.

Patients should be advised to go to hospital immediately should the symptoms return.

Immediate admission to a specialist stroke service is vital for those with a greater than 20% risk of developing a completed stroke. These are patients with more than one TIA in seven days or who have three or more of the following characteristics:

  • blood pressure greater than 140/90 mmHg
  • unilateral weakness or speech disturbance
  • symptoms lasting sixty minutes or more
  • those who have diabetes
