![]() Paralysis may affect only the face, an arm or a leg, but most often, one entire side of the body and face is affected. Paralysis is a common outcome of stroke, often on one side of the body (hemiplegia). Clot busting drugs do not seem to be effective in treating spinal cord stroke.īrain CVA can affect the entire body, including paralysis or paresis (partial paralysis), cognitive and memory deficits, speech and visual issues, emotional difficulties, daily living challenges, and pain. Effects of a spinal cord stroke can include alteration in mobility and function. Paraplegia or paraparesis involves the lower part of the body. Tetraplegia or tetraparesis (quadriplegia) involves the body and all four limbs. Spinal cord CVA will result in complete (-plegia) or incomplete (-paresis) paralysis on both sides of the body depending on the level of injury in the spinal cord. Therefore, pressure within the CNS will compress soft nerve tissue. The spinal cord and brain are contained in rigid bones so swelling is constricted. Surrounding tissue can be affected by an increase in swelling of the area. When a CVA occurs, nerve cells in the affected area of the CNS can’t function due to a lack of oxygen. Most go undetected without any issues unless they rupture. These can occur anywhere in the body but are especially damaging when in the CNS (brain or spinal cord). The alignment of the artery transitioning to a vein is misaligned. ![]() An arteriovenous malformation is a bleed that occurs where an artery meets a vein. ![]() The source of this type of stroke is hypertension, aneurism, arteriovenous malformation (AVM) or bleeding disorder. Hemorrhagic strokes result from a blood vessel that ruptures and bleeds into the surrounding brain or spinal cord.A TIA is an indication that a stroke can follow. A trans ischemic attack (TIA), sometimes called mini stroke, is an ischemic type of episode that resolves within 24 hours.A ischemic stroke from an unknown cause is called a cryptogenic stroke. This stops blood flow to the affected part of the spinal cord or brain leading to stroke. A clot or emboli typically originates in the heart, aorta or carotid arteries and travels to the CNS where it usually cannot pass through the tiny blood vessels. Obstructions typically result from plaque which has built up in the blood vessels than becomes dislodged and travels to the CNS. Ischemic strokes occur because of an obstruction (clot or emboli) within a blood vessel supplying blood to the brain or spinal cord.A person with loss of blood flow to the spine or brain or sudden bleeding in the spine or brain can be said to be having a “spine attack” or “brain attack.” The same process can occur in the central nervous system in either the spinal cord, brain or both. A stroke occurs when there is a change to blood flow in the central nervous system (CNS) due to damage to a blood vessel, rupture to the blood vessel or something stopping blood flow like a clot or emboli (globule of fat or other material or bubble of air.) Slowing of blood flow in the CNS can also lead to a stroke.Ī person with loss of blood flow to the heart is said to be having a heart attack. A CVA most often occurs in the brain but, very rarely, it can also occur in the spinal cord. When something happens to the blood flow in the central nervous system, a cerebral vascular accident (CVA) or stroke occurs.
