Not a TIA or stroke: With the understanding that anything is possible, a scintillating scotoma is generally indicative of temporary arterial spasm as occurs in the prodrome to a migraine headache. Migraines are not a risk factor for future stroke to the best of my knowledge.

MIgraine: Scintillating scotoma is a common symptom of migraine. Migraines are believed to marginally increase risk of strokes and tias later in life. Unfortunately there is not much data about this.
