Most symptoms, such as hallucinations and delusions wax and wane over time, suggesting a functional rather than a morphological brain disturbance. Moreover, most patients suffering from schizophrenia acquire the disease early in life (between 18 and 30 years) and may live well into their sixties or seventies. Even if, in post mortem studies, brain abnormalities are found, it is virtually impossible to determine whether these disturbances are related to the cause of the illness, or are a result of it, or due to the (many) treatments these patients usually undergo throughout life.
