An unusual case of functional neurological disorders and psychogenic coma following physical assault: Clinical and medico-legal considerations

Functional neurological disorders can have different clinical manifestations, including coma, in the setting of an unknown etiology. In this article, we present a case of a young man affected by intellectual disabilities who, after a physical assault reported serious neurological alterations and a functional coma. This case shows how a stressful psychophysical event can bring acute and variable neurological manifestations of functional significance to a victim with previous intellectual disabilities. Despite the growing interest in this field, research is still very limited and studies in this field could better explain the nature of the psychogenic coma. From a medico-legal point of view, problems of evaluation may emerge for these disorders emerge as a result of acute psycho-physical stress and without any detectable structural alterations.
