I am sorry to hear of all the problems you son is experiencing following his GBS. GBS does not directly affect the brain but is a life-threatening and life-changing event that can have a huge impact on people’s lives. It is not a “trauma” in the usual sense of the word but is certainly an emotionally traumatic event and depressi0n and anxiety are common following the acute illness.. Most people recover a little more quickly than your son but psychological counselling can be needed. Your son has clearly been affected by this in a major way and it is critically important to talk to your doctor so that your son’s mental welfare can be taken care of. Gareth Parry
