Junior strokes are strokes that people below the age of 18 get. You're talking bout Mini-stroke, or what's actually called a Transient Ischemic Attack (TIA for short), which causes stroke like symptoms that clear up in minutes. While they aren't considered strokes because they don't cause brain damge they are just as dangerous as regular strokes and I don't even want to get into the chance of Jack having had silent strokes.Didn't he recently confirm that the number of AMA-certified strokes he's had were 3? But the others were like junior, not-really strokes?
