Functional Neurological Symptom Disorder in an Adopted Child with Tourette Syndrome
Author(s): Vishnupriya Veeraraghavan
Conversion disorder is featured by the presence of deficits affecting the motor and sensory functions without any organic basis. It excludes the symptoms fully explainable by a general medical condition, substance abuse or culturally sanctioned behaviour. It mimics a neurological disorder. Dissociative/conversion disorders affect nearly 31% of children and adolescents. These children experience pivotal impairments in their academics, and daily functioning. Incidence of psychiatric comorbidities such as anxiety and depression is high in these population. Pseudoseizures followed by motor symptoms were the common presentations of conversion disorder in adolescents in India. Few of the other symptoms are weakness, aphonia, gait disturbances, abnormal movements, loss of vision and severe pain. Hysteria was observed to be the commonest neurotic disorder in children. Conversion disorder is by far the commonest form of somatoform disorder found in children. Latest research proves neural correlates for persons with genetic susceptibility for conversion symptoms. Study by Kozlowska states that larger grey matter volume in the supplementary motor area, superior temporal gyrus, and dorsomedial prefrontal cortex reflects the genetic variability that predisposes the children to react to psychological stress with functional neurological symptoms.
