Hi. My friend had stroke years ago ended with anomia, dysphasia, paraphasia and conductive aphasia. He still have limping when walking fast, but not to the way that prevents him from driving or doing any daily activities. The only big problem is his conductive aphasia, it gets worse under unusual stress. The issue with that is sometimes he cannot control his nerves under worries and loses the ability to speak coherently. His handwriting is slightly good but get worse under pressure. I wonder if his disability falls under the hidden disability? He faces difficulties when trying to reply or respond to people as he takes longer time to reply that the listener thinks that he is not focusing or out of the subject, but the fact is that if his anomia and the paraphasia preventing him from giving straightforward answers which put him under misunderstanding by the others. I don't know how to explain this to people but by saying he had stroke. Due to this, as it doesn't show straightaway that he is disabled, does is fall under hidden disability category? And what kind of help I can offer him? He is very clever, intelligent and talented when he talks about his favourite subject "biology" and he gives amazing approaches when delivering the information he has great knowledge; but this disability is making his life difficult from the people around him. I don't know what to do to help him?
