Always remember that feelings remain despite the loss of communication skills. Feelings may be the only way an individual can understand or express what is going on. We all communicate by emotion, expression and touch. Holding a hand, or smiling when you talk can convey more than any words. Remember to be aware of your body language and facial expression.
Harsh glances can be just as negative as harsh words.
Also, remember to include the individual. It is painful to be ignored because of difficulties in communicating.
