Understanding Stroke

How is Stroke

Diagnosed and Managed?

Acute Stroke Unit

Patients presented with acute stroke symptoms are usually directly admitted and managed in an Acute Medical Ward or Acute Stroke Unit by a multidisciplinary team including highly trained doctors, nurses, physiotherapists, occupational therapists, speech therapists, dietitians and medical social workers.



Investigations that doctors usually perform to confirm the diagnosis of a stroke include a CT and/or MRI scan of the brain and its related blood vessels.

Ultrasounds are also often used to visualise the head and neck blood vessels to see if there is any significant blockage causing the stroke.

Other tests often arranged to determine the cause of the stroke include tracings of the heart rhythm (electrocardiogram or prolonged rhythm monitoring for several days) and an ultrasound of the heart.
