In order to determine whether the diagnosis of a psychotic disorder is warranted, the health care professional has to first consider if a medical illness may be the cause of the behavioral changes. If a medical disease is identified or the psychosis is found to be the result of exposure to a medication or drug, the sufferer is assessed as having psychotic disorder due to a medical condition or psychotic disorder due to toxin exposure or withdrawal, respectively. On the other hand, if a medical cause and toxin exposure have been looked for and not found, a psychotic illness such as schizophrenia could be considered. The diagnosis will best be made by a licensed mental-health professional (like a psychiatrist or clinical psychologist), who can evaluate the patient and carefully sort through the diagnostic criteria for a variety of mental illnesses that might look alike at the initial examination, like schizotypal or schizoid personality disorder or a mood disorder with psychotic features like severe depression , or the mania phase of bipolar disorder. Other health care professionals who may treat psychotic disorders may include licensed social workers, psychiatric nurses and nurse practitioners, mental health physician assistants, and sometimes non-psychiatric physicians.
The Mellon family were the founders of the original Mellon Institute whence came the "amazing (but totally fallacious) sodium fluoride/dental caries prevention discovery" - the discovery that literally turned 'garbage into gold'. The Mellon family also founded the American Aluminum Company (Alcoa), the largest producer of the waste toxin, sodium fluoride, which, up to this point of 'caries discovery', had relatively little known commercial or industrial value, was an environmental hazard of great public concern, and was very costly in terms of safe disposal.
Neuroleptic drugs elevate prolactin levels; the elevation persists during chronic administration. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin dependent in vitro , a factor of potential importance if the prescription of these drugs is contemplated in a patient with a previously detected breast cancer . Although disturbances such as galactorrhea , amenorrhea , gynecomastia , and impotence have been reported, the clinical significance of elevated serum prolactin levels is unknown for most patients. An increase in mammary neoplasms has been found in rodents after chronic administration of neuroleptic drugs. Neither clinical studies nor epidemiologic studies conducted to date, however, have shown an association between chronic administration of these drugs and mammary tumorigenesis; the available evidence is considered too limited to be conclusive at this time.
