Transient ischemic attack

One of the medical issues that can cause paresthesia is a transient ischemic attack. This medical condition is a serious issue, and some people who have it ultimately have recurring episodes, and some end up having a stroke.

Perhaps you haven't heard of the term being discussed: transient ischemic attack. On the other hand, TIA, its abbreviation, may be familiar to you. You also may have come across the term mini-stroke at some time.

What happens in a TIA?

When someone has this issue, a certain region of the patient's brain goes through a blood supply alteration. This causes neurological dysfunction.


The symptoms that occur in a person going through a transient ischemic attack are not always the same. One that is common is to undergo vision loss (not on a permanent basis, however). As previously mentioned, paresthesia can also occur in this situation. One side of the person's body may become weak. Other symptoms may be present, and keep in mind that different symptoms may present based on the affected brain location. Additionally, the condition is considered as a stroke if symptoms last for greater than 24 hours. Causes

Mini-strokes are usually caused when something blocks a brain artery. Blood vessels that have become particularly narrow due to atherosclerosis can also lead to this situation, as can a raised resistance to flow of blood, which can occur in some diseases of the blood. Some conditions are associated with transient ischemic attacks.


A doctor or medical professional is the one who uses the proper tools and information to make a diagnosis of a TIA. Checking into the patient's history and performing a physical examination are often done. Ultrasound, X-ray and MRI technology are some testing methods that may be used. There are many differential diagnoses of medical issues that might in some ways seem similar to a transient ischemic attack.


Once this condition has been diagnosed, then the doctor may prescribe particular methods of treating it. In general, if there is a causative issue that has lead to the TIA, then it should be dealt with. Naturally, this reason alone means that there are many potential treatment methods, and they cannot be decided upon until after the issue behind the mini-stroke has been noted.
