Neuropsychiatric aspects of pediatric thyrotoxicosis.
The neurobehavioural and neuropsychiatric changes associated with thyrotoxicosis are multiple and varied. This association is well recognised although the true incidence of neuropsychiatric symptoms in thyrotoxicosis is not known. Review of available literature suggests that frank psychiatric symptoms in thyrotoxicosis may be in the order of 10%. In pediatric thyrotoxicosis the neuropsychiatric symptoms may be pronounced and may antedate the medical diagnosis by six months to one year. One of the classic presentation is deterioration in school performance. Frequently noticed cognitive and behavioural abnormalities in pediatric thyrotoxicosis are hyperactivity, irritability or anxious dysphoria, and problems of attention. Successful treatment of thyrotoxicosis usually leads to resolution of the major mental disturbances associated with it and delayed treatment possibly results in enduring neuropsychiatric problems. Awareness of neuropsychiatric symptomatology can help in early detection and appropriate management of children with thyrotoxicosis.
