    NB: Do not give aspirin if any of the above is abnormal, i.e. if it is not a TIA.

    Transient Ischaemic Attack


    TIA is medical emergency characterised by a sudden onset of focal neurological symptoms and signs resolving rapidly (average of 15 minutes, most < 1 hour), including : -

    o Unilateral weakness or sensory loss in face or limb(s).

    o Speech disturbance.

    o Unilateral visual loss.-

    N. B. : Even if the patient is improving, symptoms and signs have to be completely resolved to

    diagnose TIA. If not resolved patient should be admitted, regardless of mildness of persisting deficit, as the diagnosis may be stroke. Anyone with a focal neurological deficit of abrupt onset presenting to the Accident and Emergency department should be considered to have had a stroke unless complete resolution occurs within 1 hour.

    Loss of consciousness, pre-syncope and isolated dizziness are rarely due to TIA and should have a senior medical review before referral to the stroke service. All diabetics should have BM done.


    High risk patients (who have a stroke risk of > 5% in 48 hours) should be referred urgently, and are defined by:

    o Symptoms within the last week AND

    o ABCD2 score of ? 4

    Age? 60 years 1 point

    Blood pressure ? 140/90 1 point

    Clinical features

     Focal weakness 2 points

     Speech disturbance (and no motor weakness) 1 point

     Sensory or visual features only 0 points


     ?60 minutes 2 points

     10-59 minutes 1 point

     <10 minutes 0 points

    Diabetes 1 point

    o OR more than one episode in last week

    o All other patients with likely TIA should be referred on the same day for outpatient review in

    the TIA clinic and investigation within a week. Fax referral form overleaf to nearest TIA

    clinic. Please include a clear description of the neurological deficit, vascular risk factors, and

    ECG if possible. Please include the patient’s contact (telephone) details.


    o ECG at the time is very helpful to detect AF and signs of recent ischaemia. o FBC, ESR, U & Es, LFTs, blood glucose, cholesterol and HDL,. Clotting is not required

    (unless on Warfarin).


    o Give 300 mg loading dose of aspirin. Start or continue antiplatelet treatment with aspirin

    75mg. If there has been previous GI bleeding on aspirin, then aspirin plus a PPI is less likely

    to cause a rebleed than Clopidogrel alone. Only if there is genuine allergy to aspirin should

    Clopidogrel 75 mg be used. Do not combine Clopidogrel with aspirin.

    o Patients with classic TIA on warfarin should simply continue Warfarin if their INR was not

    outside their therapeutic range. Patients in AF without warfarin do not require admission for

    anticoagulation unless they meet the admission criteria given above.

    o We will counsel re lifestyle changes and address the issue of statins and Dipyridamole at the

    TIA clinic.


    o Patients with high immediate risk of stroke should receive appointment for outpatient

    assessment within 24 hours (Newcastle) or attend A and E immediately for admission (North


    o Patients at lower risk will get an outpatient appointment soon (average clinic delay is < 1

    week) and may be contacted by phone to arrange this.

    o They should re-attend A&E if in the meantime they have a further event. o Notify patients that DVLA rules state no one may drive within a month of TIA or stroke, but

    the patient does not need to inform the DVLA at this stage.
