Yeah! I totally agree with you. I think we should also make effort to support and show as much care as possible to people with schizophrenia. From my experience with this condition, It is advisable to engage a schizophreniac in activities that he/she loves (That is if you know); change enviornment or residence; avoid continuous eye contact and always seek professional help like a psychiatrist or a therapist. Always seek help!
Also, early detection is very important. So as a friend or family member, when you start observing abnormal signs as described in this post, try to take the person for a medical check up or make the person see the need to.

This article is so detailed and informative, you took your time on this. Kudos!
