Question to any who might know, including Mrs Silverback:
Is an "ischemic stroke" different from a "TIA - Transitory Ischemic Attack"? Is it the same thing, only more severe, with more consequences?
I ask because my grandmother and my dog used to get those and the effects didn't last long, but they were considered strokes. Thanks for any info anyone has. Perhaps that will help.
You're pretty much spot on. Per the link below:
Ischemia (lack of blood)in the brain is subdivided into three categories, based on symptom duration. All three categories refer to the same disease: the categories help doctors determine the best tactics for stroke prevention and treatment. No matter what the classification, all three events should be treated seriously
TIA: Transient ischemic attack, or "mini stroke," symptoms last less than 24 hours, and occur when circulation to an area of the brain is temporarily restricted. On average, in fact, TIA symptoms last only two to thirty minutes and no permanent brain damage occurs. TIAs do, however, suggest blood vessel disease and a third of all people who experience TIA will go on to suffer a stroke.
RIND: Reversible ischemic neurologic deficit symptoms last longer than those of a TIA. In fact, RIND symptoms generally last longer than 24 hours, but less than a week. Fortunately, however, RIND symptoms are transitory, occurring when blood flow to the brain is restricted temporarily. No permanent brain damage occurs, but RIND further increase the risk of having a stroke.
Stroke: Symptoms of a major stroke persist for longer than 24 hours and are usually more severe than those of a TIA or RIND. A stroke occurs when blood flow is blocked significantly for a prolonged period or when circulation is stopped completely. Brain damage from this condition is permanent. Stroke injury can lead to paralysis, sensory problems, speech impairment, and even sudden death.
