Although Freudian therapists have claimed success for many clients with mild neuroses, psychoanalysis is regarded as inappropriate for people experiencing more serious mental disorders, such as schizophrenia. Many of the symptoms of schizophrenia, such as paranoia and delusional thinking, mean that those with the disorder have lost their grip on reality and cannot articulate their thoughts in the way required by psychoanalysis. This suggests that Freudian therapy may not apply to all mental disorders.
