Reading list: Chemical imbalances are bogus and mythical by Loren R. Mosher M.D.

See also: Psychiatrist Loren Mosher resigns from the American Psychiatric Association (APA) because of bogus scientific claims related to chemical imbalances and corrupt support of the drug companies to perpetuate this myth.

"Presented below is an annotated bibliography addressing today's widely held belief system about the causes and treatment of disturbed and disturbing behavior usually labeled as some form of serious mental illness. As "schizophrenia" is psychiatry's most vexing and perplexing "disorder" and viewed as the most serious of the "mental illnesses" it is the primary focus of this list. It excludes children. It is not exhaustive, but is representative." (Loren R. Mosher M.D.)

"Today's dominant theory of serious" mental illnesses" posits them to be genetically determined (i.e., inherited), biochemically mediated (via "chemical imbalances"), life-long" brain diseases"(with associated specific neuropathologic changes) whose cause(s) and course is more or less independent of environmental factors is not supported by existing evidence. A critical review of the scientific available evidence reveals no clear indication of hereditary factors, no specific biochemical abnormalities, and no associated causal neurologic lesion(s). However, a number of environmental factors have been found to be related to their cause(s) and course(bibliography in preparation). It is also generally held that the anti-psychotic drugs are the mainstay of treatment and should, in most cases, be taken for a lifetime. In fact, the data indicate that neuroleptic drug treatment is not usually necessary (especially in persons newly identified as psychotic) if a proper interpersonal environment and social context is provided in alternatives to hospital care. It also appears that has drug treatment has resulted in less favorable long-term outcomes than was the case before anti-psychotic drugs were introduced. Furthermore, anti-psychotic drug treatment is associated with the induction of irreversible brain pathology (resulting in reduced intellectual and abnormal motor functioning) and shortened life expectancy. Pre-neuroleptic drug era long-term follow-up studies indicate that recovery can not only occur, but is to be expected in the majority of cases. Ergo, so called "chronicity" in "mental illness" is likely the result of its medicalization, institutionalization with its social network disruption, marginalization, discrimination and the less specific social consequences (e.g. poverty) that accompany these processes." (Loren R. Mosher M.D.)

"Conclusion: the brain abnormalities attributed causal significance in mental illness are most likely the result of neuroleptic drug treatment." (Loren R. Mosher M.D.)

(He states that tardive akathisia may be thought of as a disease of the basal ganglia, much like Parkinson's, Huntington's and Wilson's. MRI studies have demonstrated basal ganglia lesions in TD patients, especially in the caudate nucleus. Basal ganglia diseases all cause behavioral instability and intellectual impairment (even psychosis and dementia)).

In 24 studies, TD patients were found to do worse. The more severe the TD, the greater the impairment in cognitive function.

(Both tardive akathisia and tardive dyskinesia are associated with more cognitive deficits and negative symptoms. This association is stronger with TA than with TD. The implication is that movement disorders seen in TA and TD are "but one feature of complex syndromes that include motor and cognitive features. A comparison must be made with other movement disorders, such as Parkinson's disease and Huntington's disease, in which neuropsychological deficits, and indeed subcortical dementia are known to occur.")

Deterioration derives primarily from emergence of TD. They find that marked deterioration in cognitive function occurs at same time as emergence of movement disorder.)

(Use of neuroleptics is associated with volume reduction (or atrophy) of frontal lobes and temporal lobes. As the brain atrophies in this way, here is said to improvement in delusions and thought disorder (the brain-damaging principle at work). A greater rate of reduction in volume is associated with higher dose. At the same time, reduction in volume is associated with decline in some neurobehavioral functions.)
