A stroke can be caused by either:
A blockage of a blood vessel in the brain causes a lack of oxygen to the surrounding brain tissues. This means the brain tissue can be damaged or dies.
When blood vessels bleed in the brain this can also cause damage to surrounding tissues. A stroke caused by a bleed can be due to years of high blood pressure. It can also happen because of a bulge in the wall of a brain artery called an “aneurysm”. Abnormal connections between arteries and veins can also cause this kind of stroke.
When a patient has a severe stroke they may need to come to the ICU. This is because severe strokes can cause breathing problems that cause a drop in level of consciousness. This means a breathing tube is required to help support the lungs. A severe stroke can also affect swallowing, speech and other bodily functions. Many patients need extra support for these things that can only be provided in ICU.
The treatment for a stroke is different depending on:
Treatments for stroke caused by a blockage can involve strong medications to help break up the clot. Some people may require surgery to remove the clot.
Patients with a stroke caused by a bleeding vessel may need surgery to clip the arteries involved. Some patients may need surgical repair of an aneurysm or a vessel malformation.
For some people, recovery may be quick over days or even shorter. For many other people, recovery takes several months or longer. How much support people need after a stroke varies a lot. Some people require extra support services at home or an admission to a nursing home. Other people may be able to go home with just a small amount of follow-up therapy.
The National Stroke Association in the US* reports that after a stroke:
A multi-disciplinary team are involved with helping patients with rehabilitation after a stroke. This team includes medical staff, occupational therapists and physiotherapists. The rehabilitation team begin working with patients as soon as possible.
Things that will assist your recovery are:
The neurologists will often prescribe some ongoing medications to help prevent further strokes.
