Is their balance off?

  • Are they able to stand straight and tall?
  • Or do they slump to one side?
  • Do they appear to have lost strength on one side of their body?
  • Are they leaning to one side when they try to walk?
  • Are they veering off to one side?
  • Are they dragging the foot on the side they are leaning toward?
  • Can they tell you whether they can feel the side that they are leaning toward?

Is their speech slurred or face droopy?

  • Are they having problems speaking?

  • Do they sound like they have some thing in their mouth when they speak?
  • Are they saying the appropriate words (do their words make sense) when they speak?
  • Does one side of their mouth droop down?

Is one side weak or numb?

  • Ask the person to raise both their arms up together. Does one arm begin to fall down?
  • Ask the person to squeeze your fingers with each hand; is one hand weaker than the other?
  • If you ask the person to try to hold something like a pen, can they do it without any difficulty?
  • Can the person feel you touch them on their arm? Lightly touch them on the skin of both arms, and ask them if the feeling is the same on each.
