There are two main types of stroke, and although the symptoms are similar, the treatments are different. Diagnostic imaging shows the type of stroke and the location of the blockage, which helps doctors determine the most effective treatment:
Ischemic strokes are caused by a blood clot that blocks the passage of blood to the brain.
For most ischemic strokes, teleNeurologists will recommend the administration of an intravenous thrombolytic drug to dissolve the clot. It must be administered within a certain timeframe after the onset of stroke symptoms. This is why it is so important to recognize the signs of stroke and get medical treatment immediately:
Hemorrhagic strokes are caused when a burst blood vessel interrupts the flow of blood to the brain.
In a hemorrhagic stroke, options include thrombectomy, surgical removal of the blockage using a tool called a stent retriever. If the teleNeurologist recommends endovascular treatment, the patient may be transferred to a more specialized healthcare facility.
