COP2//Sigmund Freud

Sigmund Freud experimented on patients with schizophrenia as part of his psychoanalysis theories. Here is some background information on the scientist. 

Sigmund Freud (1856-1939) is considered the father of psychoanalysis, which may be the granddaddy of allpseudoscientific psychotherapies, second only to Scientology as the champion purveyor of false and misleading claims about the mind, mental health, and mental illness.  For example, in psychoanalysis schizophrenia and depression are not brain disorders, but narcissisticdisorders. Autism and other brain disorders are not brain problems but mothering problems. These illnesses do not require pharmacological or behavioral treatment. They require only "talk" therapy. Similar positions are taken for anorexia nervosa and Tourette's syndrome (Hines 1990: 136). What is the scientific evidence for the psychoanalytic view of these mental illnesses and their proper treatment? There is none.

Modern psychoanalysis may be evidence-based, but Freud's work was based on personal insights and inferences from work with patients, his and those of other therapists. This entry makes no claims about the efficacy of current treatments by psychoanalysts. It is about Freud and some of his early followers.

The most fundamental concept of psychoanalysis is the notion of the unconscious mind as a reservoir for repressed memories of traumatic events which continuously influence conscious thought and behavior. The scientific evidence for this notion of unconscious repression is lacking, though there is ample evidence that conscious thought and behavior are influenced by nonconscious memories and processes. And there is ample evidence that childhood abuse, sexual or otherwise, can seriously affect a person's mental and physical well being. There is also ample evidence that not everyone who is sexually abused grows up to have psychological or mental problems.
