You are describing what has a high probability of being a Transient Ischemic Attack or TIA= in lay terminology, ministroke. The typical duration of such an attack is under an hour. However, if this just happened now then, the chance of his suffering a stroke in the next 7-30 days is significantly higher than the normal population. Therefore, I would not delay in taking him to a hospital (preferably one with a program of Stroke Excellence such as a teaching center or academic institution) and explaining the situation. They can then, check him over (even if he s back to normal) and make sure he doesn t require something immediately done or even an overnight stay for a more indepth workup this week and consultation with a neurologist. I m afraid if you go to a standard community hospital they are likely to do a few tests and then, if he s neurologically back to complete normal they will discharge him and tell you to follow up with a neurologist but that is not how you want this handled. Good luck at finding an appropriate place to take your dad for a workup tonight (well, it s night time here). If you found this information to be useful then, your small bit of written feedback and STAR RATING will be greatly appreciated.
