The symptoms include temporary loss of sensation in any part of the body, black outs,
vision loss, tingling,
loss of function of a limb etc. It is common in people with high blood pressure, diabetes, peripheral vascular disease, and high cholesterol. Hence all predisposing factors to TIA should be ruled out like polycythemia vera, sickle cell disease, atherosclerosis, diabetes, hyperviscosity syndromes, hypertension etc.
Generally this can happen several times before an actual stroke happens.
