Rethink Mental Illness is a mental health charity in England. The organisation was founded in 1972 by John Pringle whose son was diagnosed with schizophrenia. The operating name of 'Rethink' was adopted in 2002, and expanded to 'Rethink' Mental Illness' (to be more self-explanatory) in 2011, but the charity remains registered as the National Schizophrenia Fellowship, although it no longer focuses only on schizophrenia.
