For people who have had a stroke: Aspirin can help prevent a second stroke or a transient ischemic attack (TIA), which is often a warning sign of a stroke. For people who have never had a heart attack or stroke: Talk to your doctor before you start taking aspirin every day.
In patients with a history of stroke or transient ischemic attack (TIA), 50 mg/day has been shown to be effective in men and women. In acute stroke, 160 mg/day is effective in preventing recurrent stroke or death.
Background. Aspirin is recommended for secondary prevention after transient ischaemic attack (TIA) or ischaemic stroke on the basis of trials showing a 13% reduction in long-term risk of recurrent stroke.
Immediate treatment with aspirin can substantially reduce the risk and severity of early recurrent stroke. This finding has implications for doctors, who should give aspirin immediately if a TIA or minor stroke is suspected, rather than waiting for specialist assessment and investigations.
Encouraging people to take aspirin if they think they may have had a TIA or minor stroke – experiencing sudden-onset unfamiliar neurological symptoms – could help to address this situation, particularly if urgent medical help is unavailable.
“We have since learned that in an era where we control hypertension and high cholesterol better for primary prevention, aspirin may be only minimally beneficial with an increased bleeding risk, especially for older adults,” Dr. Ziaeian says.
2. High Risk TIA (ABCD 4-7) with full recovery should be given a loading dose of Clopidogrel 600mg and Aspirin 300mg after CT Brain scan to rule out haemorrhage and other significant stroke mimics. This is then followed by dual antiplatelet therapy (DAPT) with Clopidogrel 75mg and Aspirin 75mg once daily for 21 days.
If a TIA is suspected, you should be offered aspirin to take straight away. This helps to prevent a stroke. Even if the symptoms disappear while you're waiting for an ambulance to arrive, you still need to be assessed in hospital. You should be referred to see a specialist within 24 hours of the onset of your symptoms.
Yes. Although your risk of having a stroke is higher if you have already had a stroke or a transient ischaemic attack (also called a TIA or mini-stroke), you can reduce your risk of another stroke. It's important that you take the medication that you're prescribed, and make any lifestyle changes you need.
Benefits and risks of blood-thinning medication
Taking blood-thinning medication is often one of the main ways you can reduce your risk of a stroke if you have had a stroke or TIA, or have a heart condition.
TIAs are often warning signs that a person is at risk for a more serious and debilitating stroke. About one-third of those who have a TIA will have an acute stroke sometime in the future. Many strokes can be prevented by heeding the warning signs of TIAs and treating underlying risk factors.
A transient ischaemic attack (TIA or mini-stroke) is the same as a stroke, but the symptoms last a short time. You get stroke symptoms because a clot is blocking the blood supply in your brain.
If you have had a TIA, you could be given: • clopidogrel • aspirin • dipyridamole and aspirin together • dipyridamole alone, if you can't take aspirin.
Taking aspirin isn't advised during a stroke, because not all strokes are caused by blood clots. Some strokes are caused by ruptured blood vessels and taking aspirin could make these bleeding strokes more severe.

The best way to help prevent a TIA is to eat a healthy diet, exercise regularly, and not smoke or drink too much alcohol.
About 1 in 3 people who has a TIA goes on to experience a stroke. The risk of stroke is especially high within 48 hours of a TIA . The symptoms of a TIA are similar to those of a stroke and include: Numbness or muscle weakness, usually on one side of the body.
The risk of stroke after transient ischemic attack is somewhere between 2% and 17% within the first 90 days. Among patients with transient ischemic attack, one in five will have a subsequent stroke (the most common outcome), a heart attack or die within one year.
You may have more than one TIA , and the recurrent signs and symptoms may be similar or different depending on which area of the brain is involved.
The “1-3-6-12-day rule” is a known consensus opinion with graded increase in delay of anticoagulation between 1 and 12 days after onset of IS/TIA according to neurological severity and reasonable from the perspective that the timing should vary according to the severity.
Recognising the signs of a TIA
Face – the face may have dropped on 1 side, the person may not be able to smile, or their mouth or eye may have drooped. Arms – the person may not be able to lift both arms and keep them there, because of weakness or numbness in one arm.
You may return to any of your previous activities/work as soon as you feel well enough and safe (as long as you follow driving restrictions). You may feel tired for a while after a TIA – pace yourself and listen to your body.
You must stop driving for at least 1 month after a transient ischaemic attack ( TIA ) or mini-stroke. This includes amaurosis fugax or retinal artery fugax. You can restart only when your doctor tells you it is safe.
It has been found in a study that stress apparently raises the risk of a Stroke or Transient Ischemic Attack (TIA) by 59%. A TIA is a mini-stroke caused by a temporary blockage of blood flow to the brain.
