[A case of conversion disorder analyzed from a psychodynamic, psychophysiologic, and morphodynamic perspective]

This paper presents a case of conversion disorder characterized by sensory paralysis that involved the right half of the body, a motor deficit consisting of permanent contracture in flexion of fingers 2-5 of the right hand (clenched fist syndrome), and a visual alteration compatible with homonymous hemianopia and amblyopia. The patient initially presented a clinical picture of depression as well as frequent gynecological disorders. The author evaluates important aspects of the psychogenesis of the clinical picture and emphasizes the identifying aspects and primary and secondary gains. Consideration is given to the distinct therapeutic strategies used (psychotherapy, autogenous training, hypnosis), and the case is analyzed from a morphodynamic point of view. The author concludes that the organic basis of the clinical picture would be localized in the posterior nuclei of the thalamus.
