• Chest X-ray, electrocardiogram (ECG)

• Ultrasound
  Studies of the blood vessels in the neck and skull (Carotid ultrasound, transcranial Doppler), and of the heart (Echocardiogram): To detect conditions that may be predisposed to stroke.
• Angiogram
  A small tube is inserted into the groin and passed along the blood vessel till it reaches the brain. A dye is injected and x-ray pictures are taken. These provide information on the location and severity of vessel blockage or bleed.
