First, it is important to note that when a migraine is associated with neurologic symptoms, this is termed complicated migraine, meaning the usual
headache and other
headache associated
symptoms are accompanied by unusual
symptoms such as tingling, numbness, weakness etc.
A TIA, or transient ischemic attack, is due to a transient decrease in blood flow to a part of the brain. The symptoms that occur depend on which area of the brain is not receiving blood.
