Schizophrenia is a mental illness that affects the way someone thinks, speaks, or feels to such a degree that they have an altered perception of reality.
The average life expectancy for someone with schizophrenia is then or more years less than average due to physical health problems and the higher suicide rate.
Disorganised schizophrenia is characterised by speech being disorganised and hard to follow, as well as the person having inappropriate moods for a given situation, with no hallucinations.
