Abstract
Intellectual Disability (ID) is one of the most common disorders encountered in child psychiatry settings. Recognition of syndromic ID cases is critical in terms of treatment processes and prognosis. With this paper, we have aimed to present the clinical course of a 16 year old male adolescent that exhibited symptoms of Holmes-Schimke syndrome, a rare disorder. Along with severe ID, he had other symptoms such as microcephaly, dysmorphic facial features, hypothyroidism, thyroid atrophy, congenital hear disease, hypogenitaliasm (micropenis and testicular atrophy), polythelia, psychomotor developmental delay, epileptic episodes, obesity and polydacytly. The case also had psychiatric symptomatology including hyperphagia, hyperactivity, angry outbursts, limited communication skills. He was started on a combined regimen of methylphenidate, quetiapine and valproic acid. He was also attending special education classes. With this report, we have aimed to present one of the most rarely seen syndromes manifest itself in a child psychiatry setting, along with the process of differential diagnosis, dysmorphic features and to discuss the course of treatment, for this case.
Keywords: Intellectual Disability and Holmes-Schimke syndrome.
