Transient Ischaemic Attack
Understanding TIA (Mini-Stroke)
A Transient Ischaemic Attack (TIA), often referred to as a “mini-stroke,” occurs when there is a temporary disruption of blood supply to the brain. Although symptoms resolve within 24 hours, a TIA is a critical warning sign and should never be ignored. Without urgent medical attention, a full stroke may follow.
At the Royal Buckinghamshire Hospital, our specialist team provides fast, expert care for TIA, including diagnosis, risk assessment, and preventive treatment.
Symptoms of a TIA
Symptoms of a TIA are similar to those of a stroke, but they usually last only a few minutes to a few hours. Common signs include:
- Sudden numbness or weakness in the face, arm, or leg – particularly on one side
- Slurred speech or difficulty understanding others
- Loss of coordination or balance
- Temporary vision loss or blurred vision in one or both eyes
- Dizziness or confusion
- Difficulty swallowing
If you experience any of these symptoms, seek medical attention immediately, even if they resolve quickly.
Causes and Risk Factors
TIAs are typically caused by a temporary blockage in a blood vessel supplying the brain. Risk factors include:
- High blood pressure
- Atrial fibrillation or irregular heart rhythms
- Diabetes
- High cholesterol
- Smoking
- Obesity and physical inactivity
- Family history of stroke or heart disease
Diagnosis at Royal Buckinghamshire Hospital
We offer advanced diagnostics to determine the cause of a TIA and to prevent future strokes, including:
- Blood pressure and cardiovascular assessments
- MRI or CT brain scans
- Carotid ultrasound
- ECG or Holter monitor
- Blood tests for clotting, cholesterol, and blood sugar

- Immediate treatment to reduce stroke risk
- Medications to manage blood pressure, cholesterol, and prevent clotting
- Lifestyle guidance on diet, exercise, smoking cessation, and stress management
