As a stroke specialist, I cannot stress enough the importance of recognizing the signs of a Transient Ischemic Attack (TIA), often referred to as a 'mini-stroke.' Although TIAs may seem minor and symptoms often disappear within minutes, they serve as a serious warning that a major stroke could follow. Early diagnosis and timely intervention are critical in preventing long-term brain damage or disability.
Introductions to Mini-Strokes
Mini-strokes, also known as transient ischemic attacks (TIAs) can be frightening, and rightfully so. A TIA doesn't last long, normally only a few minutes, and doesn't cause permanent damage. Still, it can be indicative of a larger problem. It could be a warning and one you should take seriously.

Common Questions About Mini Strokes (Transient Ischaemic Attacks)
What is a mini stroke (TIA)?
A transient ischaemic attack (TIA), often called a mini stroke, occurs when blood flow to part of the brain is temporarily interrupted. Although symptoms usually resolve within minutes or hours, a TIA is an important warning sign that a full stroke may occur. Prompt medical assessment helps identify the underlying cause and reduce future stroke risk.
What are the warning signs of a mini stroke?
Common symptoms include sudden weakness or numbness on one side of the body, facial drooping, difficulty speaking or understanding speech, vision changes, dizziness or loss of balance. Even if symptoms improve quickly, immediate medical assessment is essential, as a TIA should always be treated as a medical emergency.
What causes a transient ischaemic attack?
A TIA is most commonly caused by a temporary reduction in blood flow to the brain. This may result from narrowing of the carotid arteries, blood clots, heart conditions such as atrial fibrillation or other vascular diseases. Identifying the underlying cause is essential for preventing future strokes.
How is a mini stroke diagnosed?
Assessment may include a neurological examination, brain imaging such as CT or MRI, blood tests and vascular imaging of the carotid arteries or blood vessels supplying the brain. Your specialist will recommend the most appropriate investigations based on your symptoms and medical history to determine the cause and guide treatment.
Can a mini stroke be prevented from happening again?
Yes. Treatment focuses on reducing the risk of a future stroke by managing the underlying cause. Depending on your condition, this may include medication, lifestyle modifications, management of high blood pressure, diabetes or cholesterol, or treatment for carotid artery disease. Regular follow-up helps monitor your condition and supports long-term stroke prevention.
What is a Mini-Stroke (TIA)?
The symptoms of a mini-stroke and full-blown stroke are often similar, just much abbreviated during a TIA. It is common to have more than one TIA following another. The symptoms of a stroke and TIAs include:
- Dizziness, and loss of balance which may result in a fall
- Slurred speech
- Weakness or numbness on one side of the face
- Possible weakness in one arm and leg as well
- Double vision or blindness in one or both eyes
A transient ischemic attack (TIA) usually lasts only a few minutes, with symptoms disappearing within an hour or up to 24 hours. Though you may feel fine afterward, a TIA is often a warning sign of a future stroke. One out of every five people who experience one or more TIAs will have a stroke, a heart attack, or die within one year, according to the National Library of Medicine.
What Causes TIAs?
A transient ischemic attack is the result of a clot restricting blood flow to an area of the brain. Some TIAs are caused by a clot forming elsewhere in the body and moving to one of the arteries which supplies blood to the brain. The issues behind a TIA and a stroke are similar with the difference being the length of time the blockage stays.
TIA Risk Factors
Many issues can contribute to TIAs, some of which can be controlled, others cannot. They include:
- High blood pressure
- High cholesterol
- Diabetes
- Obesity
- Smoking
- Alcohol
- Family history
- Aging
These factors can cause blockages of circulation to the brain and blood clotting, all of which increase the risk of stroke.
Treatment Options for Mini-Strokes: Individualized Approach
If you are or see someone having symptoms of a TIA or stroke, do not wait, call 9-9-5 at once. Waiting to do so can significantly affect the outcome.
Depending on how severe the incident was, possible treatment options include lifestyle management, medication, and surgery.
Lifestyle Management
The best way to treat a stroke is to prevent a stroke. It is something the Supreme Vascular and Interventional Clinic believes in. Lifestyle management goes a long way toward prevention.
Dr. Manish Taneja, our stroke specialist in Sinagpore, strongly advocates for anyone with any predisposing conditions or symptoms to partake in stroke screening.
While we cannot do anything about our family history or the normal aging process, we can work to get a proper amount of exercise, support a healthy weight, and avoid smoking and alcohol.
Medication and Surgery
Your physician may prescribe medication to aid in the treatment of high blood pressure, high cholesterol, or diabetes, and possibly blood thinners, which will help in the prevention of TIAs, stroke, and other diseases.
In some cases, surgical intervention may be necessary following TIAs or a stroke. About 10-15% of TIA patients experience a full stroke within 3 months, and a third have one within a year. Since TIAs can occur just hours or days before a stroke, it's critical to seek medical help right away if you notice symptoms. Call 9-9-5 or get to the nearest emergency room immediately if you or a loved one experience symptoms of TIA. TIAs are considered as warning signs for future stroke.
When to Consider a Mini Stroke (TIA) Specialist Assessment in Singapore
A transient ischaemic attack is an important warning sign that deserves prompt medical attention. Even if symptoms have resolved completely, identifying the underlying cause can significantly reduce the risk of a future stroke.
Consider arranging a specialist assessment if you:
- Have experienced sudden weakness, numbness, difficulty speaking or vision changes that resolved within minutes or hours.
- Have been diagnosed with a transient ischaemic attack (TIA) and would like to understand your stroke risk.
- Have been found to have carotid artery narrowing or other vascular conditions affecting blood flow to the brain.
- Have risk factors such as high blood pressure, diabetes, high cholesterol, atrial fibrillation or smoking.
- Would like a second opinion regarding investigations, treatment or long-term stroke prevention.
- Have experienced recurrent episodes of neurological symptoms, even if they resolved completely.
At the Supreme Vascular and Interventional Clinic, assessment includes a comprehensive review of your symptoms, brain imaging, vascular imaging and individual stroke risk factors. Your specialist will identify the underlying cause of the TIA, explain the most appropriate treatment options and develop a personalised plan to help reduce your risk of future stroke through ongoing monitoring and continuity of care.
Seek emergency medical attention immediately if you experience sudden weakness or numbness on one side of the body, facial drooping, difficulty speaking, vision loss, severe dizziness, loss of coordination or sudden confusion, as these may indicate a stroke requiring urgent treatment.

We've Got You Covered for Specialized Stroke Screening, Prevention, and Management
Imagine heart attacks where the blood flow to your heart is blocked. Similarly, a stroke occurs when the blood flow to your brain is interrupted becoming a "brain attack". When blood supply does not reach a certain part, brain cells begin to die. Different types of stroke include ischemic strokes (blockage of blood vessel due to blood clot) or a mini stroke, a TIA (transient ischemic attack), with no permanent damage yet serious. Stroke also occurs when a blood vessel in the brain pops causing bleeding in the brain.
When a stroke occurs, the symptoms of stroke depend on how blood flow to the brain is affected. Individuals at high risk and even higher risk (family history) often have high blood pressure, atrial fibrillation, or another risk factor for stroke, all of which increase the risk of stroke. Disrupted blood flow can even damage the blood vessel in the brain and affect one side of the body. Having a stroke doesn’t mean it has to lead to permanent disabilities. Recognizing early warning signs is essential to reduce the risk, and in some cases, procedures such as carotid endarterectomy may help increase the blood vessel in the brain and restore healthy circulation.
Certain areas of the brain can be affected by stroke and some symptoms of a stroke including cardiovascular disease, diabetes, and high blood sugar levels increase the risk of stroke whereas an active lifestyle or controlling high cholesterol reduces the risk.
