La classification traditionnelle des maladies mentales et celle d’Henri Ey y sont discutées et un néo-organodynamisme est présenté. La phase aiguë d’une maladie mentale n’est sans doute qu’une modification temporaire de la maladie de base. La nature de cette dernière peut se décrire par l’importance de la dégénérescence organique. Alors qu’un état psychotique constitue le trouble de base, une phase agrégative aiguë se manifesterait en proportion du degré d’excitations anormales du réseau neuronal. En s’appuyant sur une pluralité d’états mentaux, il est possible de représenter avec précision l’état des patients psychiatriques, qui varie de façon néo-organodynamique avec l’évolution. De la même façon, grâce à la classification proposée, il devient possible de procéder à une recherche clinique comparative des effets des médicaments et des modifications biochimiques. Le concept de « voie accessoire » est introduit. Les contraintes et tensions mentales, ainsi que les actes rituels, promeuvent une construction et une réorganisation du réseau neuronal, qui se fige sous l’effet des répétitions. L’encodage de ce nouveau réseau neuronal dans le subconscient crée une dérivation qui finit par se fixer en tant que « voie accessoire », à l’instar du faisceau de Kent dans le syndrome de Wolff-Parkinson-White. Lorsque la « voie sous-conductrice » est dominante, le patient ne peut plus prendre en considération quoi que ce soit, y compris lui-même. In fine, l’histoire du psychisme est celle d’une hiérarchisation mentale, construite par des voies accessoires et l’encodage dans le subconscient des états mentaux associés.

Dogmatically conflicting psychological and biological theories make the foundations of psychiatry fragile.

Traditional and Henri Ey's classifications of mental illness are discussed and the neo-organodynamism is proposed. The principle of the accessory pathway is also proposed.

The acute phase of disease may only be a temporary modification of the basic mental illness, the nature of the latter can be expressed in terms of the depth of the organic degeneration. The psychotic state consists of the basic disorder and its acute aggregative phase that is in proportion to the degree of abnormal excitations of neural network. In my classification, mental illness is classified from a normal stage N to X. The degree of acute aggravation is staged from 0 to 7. The twelve stages of organic degeneration multiplied by the eight stages of acute aggravation results in a product of 96 mental stages. By applying this, we can accurately represent the conditions of psychiatric patients that change neo-organodynamically over time. At the same time, clinical comparative research, such as the effects of medicine and of biochemical changes at one time becomes possible. The mental automatism, the mechanism of acute psychosis and treatment concept are discussed with this theory. And this theory may explain what the mental illness is, what the delusion is and what the endogenous psychosis is. Mental pressures or ritual acts promote construction and the reorganization of neural network, and it is fixed by repeating itself. Coding to the subconsciousness of a new neural network namely bypass will be made, and it is immobilized as an accessory pathway like the bundle of Kent of the Wolff–Parkinson–White syndrome. This is the principle of the accessory pathway. When the accessory pathway is dominant, the patient cannot consider anything like himself. This condition shows the low level of his psychic energy (psychasthénie). The history of a mind hierarchy that is constructed with the accessory pathways may be a history of mind. And the history of a mind hierarchy should be what the psychic body is.

From the viewpoint of the neo-organodynamism, the conception of organic degeneration is consisted of 1) tissue degeneration literally and 2) generation of accessory pathway by the reorganization of the synapse. The symptoms may be irreversible in the case of the tissue degenerations. But the symptoms that are induced by the accessory pathway may be reversible. If the conductivity of the main pathway becomes dominant as before, the symptom by the accessory pathway has a possibility of the improvement. But the accessory pathway will be remained even if the conductivity of the main pathway becomes dominant as before. One's usual personality is defined as a predominant state of the main pathway. Healing is to return to one's usual personality from the accessory pathway predominant state. In the organic degenerations that are the essence of mental illness, rehabilitation (psychotherapy, cognitive behavioral therapy, mental counseling, etc.) is essential to recuperate lost functions. For the positive symptoms, which are the secondary effects of organic degenerations, medication that focuses on the synaptic neurotransmitters will be effective. Theoretically, the anti-epileptics may be might be designated as the fundamental treatment for the acute aggravation phase because of the abnormal firings of the neuronal network.

Neo-organodynamism is proposed as a minimum clinical classification of mental illness for psychiatrists. By using this, we can understand that the psychosis is not the special disease, but everyone has the possibility of onset. Neo-organodynamism will eliminate the prejudice against mental illness.
