    hello, 124707 --

    a TIA (see PS1), which standards for transientischemic attack, is a sort of a mini-stroke (PS2); it is caused when the flow of blood to part of the brain is blocked, often by a blood clot, but then becomes unblocked when the clot or other cause dissolves or disappears. in other words, the effects of a TIA are temporary, whereas the effects of a stroke are permanent. a TIA is a warning that a person may eventually have a full-blown stroke.

    a seizure (PS3, PS4) is a convulsion; it is the result of abnormal electrical signals sent from the brain thru the nerves to the muscles. seizures can involve mild or violent shaking of the body; they can also manifest as what looks like a conscious state where the person is nonetheless unaware of what is happening around him/her (these are called absence seizures).

    in short, TIAs are caused by a blockage of the flow of blood to the brain, whereas seizures are caused by abnormal electrical signals from the brain.
