Welcome to the MedHelp forum!
TIA or transient ischemic attack is a mini stroke that happens when the blood supply to brain is temporarily cut off. The episodes last for a maximum of 24 hours and then resolve or a new symptom starts. 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.
Generally this can happen several times before an actual stroke happens. This is a warning sign for the body. If you have such episodes, then you must get them evaluated immediately.
Hope this helps. Do discuss this with your doctor and get yourself examined. Please let me know if there is any thing else and do keep me posted. Take care!
