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.
