What's the difference between a mini-stroke and an epilepsy? which is more serious?

Mini strokes: A mini stroke implies a blockage in a vessel of the brain supplying a small area of the brain and causing an area of cell death and cell compromise. Epilepsy is an illness caused by abnormal discharges of the brain. It has many causes. It usually has some type of seizure. Usually mini strokes are worse as they portend to major strokes.

Neurologic Quandary : "mini strokes" or transient ischemic attacks are tempory interruptions of blood and oxygen to areas of the brain often due to arterial blockage or spasm. Epilepsy is a condition marked by history of multiple seizures. "mini strokes" can result in seizures, but epilepsy is a chronic condition & the seizures aren't due to vascular disease. Difficult to say which is more serious, severity can vary.

Different causes: Epilepsy or seizures, occur when something interrupts the electrical messages in the brain and it is usually chronic. Isolated seizures do not usually cause death or a stroke by themselves. There is medication that can control most seizures. Mini-strokes on the other hand are warning signs that the blood supply to a particular area of the brain is going to be shut down from arterial blockage.
