[Diagnosis of neurological symptoms of psychogenic origin].

The principles of neurological examination of patients in which psychogenic disturbances are suspected are first described. After mentioning the frequency of this type of disturbances in the medical literature, some of the most characteristic and most frequent psychogenic disturbances in neurology are described: cranial nerve symptoms, sensory disturbances as well as psychogenic paralysis including paraplegia and psychogenic disturbances of gait. A chapter is dedicated to psychogenic disturbances of consciousness and to psychogenic attacks mimicking epilepsy. Finally a description is given of those organic neurological diseases in which in our experience the erroneous diagnosis of psychogenic disturbances is most frequently made. Some recommendations, how to behave in the presence of a patient with psychogenic neurological symptoms is added.
