TIA: A TIA is a vascular event similar to angina pectoris in the heart, they both are temporary decreases in blood flow causing transient symptoms. Petit mal is a type of electrical abnormality in the brain that comes and goes. Petit mal is not necessarily vascular related, a TIA is by definition.

TIA or seizure?: A petit mal seizure is caused by an electrical disturbance in the brain, it normally lasts about 20 seconds. It is common for it to occur over and over. It often causes involuntary movement, sensation, or visual disturbance. A TIA is also a mini stroke. It is caused by loss of blood flow to part of the brain, resulting in loss of function. It lasts less than 24 hours. Hope that helps!
