Co-morbid psychiatric disorders in children with arachnoid cyst

Abstract

Arachnoid Cysts (AC) are benign lesions containing cerebrospinal fluid, and although most of them are asymptomatic, they can cause neurological symptoms like headaches, seizures, and neuropsychiatric problems. The aim of this study was to asses and document co-morbid psychiatric disorders in children with AC aged between 6 and 17. Wechsler Abbreviated Scale of Intelligence–Second Edition (WASI-II), a clinical measure used to assess the intelligence quotient (IQ) scores of the patients, Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version (K-SADS-PL; semi-structured interview) was used to assess psychiatric disorders among the patients. A total of 12 patients with AC was evaluated with an even distribution of males and females. Half of the patients had a normal IQ score with a mean IQ score of 104.5. Among patients with normal IQ scores, one patient had epilepsy and attention deficit hyperactivity disorder and two patients had epilepsy without any psychiatric disorder. The remaining six patients had moderate intellectual disability with a mean IQ of 48.2. Among them, three out of six had epilepsy and four had accompanying psychiatric disorders. It is therefore apparent that patients with AC have a high rate of co-morbid psychiatric disorders. Our study demonstrates that intellectual disability and psychiatric disorders should be evaluated in children with AC in the clinical settings.
