Some therapies do attempt to cure pedophilia, but there are no studies showing that they result in a long-term change in sexual preference. Michael Seto suggests that attempts to cure pedophilia in adulthood are unlikely to succeed because its development is influenced by prenatal factors. Pedophilia appears to be difficult to alter but pedophiles can be helped to control their behavior, and future research could develop a method of prevention.There are several common limitations to studies of treatment effectiveness. Most categorize their participants by behavior rather than erotic age preference, which makes it difficult to know the specific treatment outcome for pedophiles. Many do not select their treatment and control groups randomly. Offenders who refuse or quit treatment are at higher risk of offending, so excluding them from the treated group, while not excluding those who would have refused or quit from the control group, can bias the treated group in favor of those with lower recidivism. The effectiveness of treatment for non-offending pedophiles has not been studied. Cognitive behavioral therapy
Cognitive behavioral therapy (CBT) aims to reduce attitudes, beliefs, and behaviors that may increase the likelihood of sexual offenses against children. Its content varies widely between therapists, but a typical program might involve training in self-control, social competence and empathy, and use cognitive restructuring to change views on sex with children.
Cotards syndrome exists in three stages:

Germination stage: symptoms of psychotic depression and of hypochondria appear;
Blooming stage: full development of the syndrome and delusions of negation; and;
Chronic stage: continued severe delusions along with chronic psychiatric depression.Cotards syndrome withdraws the person with the condition from other people due to neglect of their personal hygiene and physical health. Delusions of negation of self prevent the patient from making sense of external reality, which then produces a distorted view of the external world. Such delusions of negation are usually found in schizophrenia. Although a diagnosis of Cotards syndrome does not require the patient to have had hallucinations, the strong delusions of negation are comparable to those found in schizophrenic patients. Distorted reality
The article Betwixt Life and Death: Case Studies of the Cotard Delusion (1996) describes a contemporary case of Cotards delusion which occurred in a Scotsman whose brain was damaged in a motorcycle accident:

[The patients] symptoms occurred in the context of more general feelings of unreality and [of] being dead. In January 1990, after his discharge from hospital in Edinburgh, his mother took him to South Africa. He was convinced that he had been taken to Hell (which was confirmed by the heat) and that he had died of sepsis (which had been a risk early in his recovery), or perhaps from AIDS (he had read a story in The Scotsman about someone with AIDS who died from sepsis), or from an overdose of a yellow fever injection.
