This paper reports a study of the nature and prevalence of behaviour problems in 258 children with mucopolysaccharide disorders. Questionnaire data obtained through the post was supplemented by home visits to 42 families in the sample and by regular discussions with families at meetings of the Society for Mucopolysaccharide Diseases. High rates of behaviour problems were found, particularly in children with Sanfilippo's and Hunter's disease aged 5 to 9 years. These included destructiveness, restlessness, and aggressiveness. Sleep problems were common across subtypes with an overall prevalence of 66%. Parents reported that they received little or no support in the management of these difficult behaviours. It is concluded that behaviour problems are a primary feature of the mucopolysaccharide disorders and place a major strain on families. Services to help families cope with these problems are urgently needed.

Sanfilippo type B is an autosomal recessive mucopolysaccharidosis (MPS IIIB) caused by deficiency of N-acetyl-alpha-D-glucosaminidase, a lysosomal enzyme involved in the degradation of heparan sulfate. It is characterized by neurologic degeneration, behavioral problems, and mental decline. Somatic features are relatively mild and patients with this disorder can reach late adulthood. It is the most common subtype of MPS in the Netherlands and probably underdiagnosed in adult persons with mental retardation (MR). In order to increase knowledge on the adult phenotype and natural history in Sanfilippo type B, we present the clinical data of 20 patients with this disorder. Sixteen of them were followed for one to three decades. Six died between 28 and 69 years of age, mainly from pneumonia and cachexia; the surviving patients were 18-63 years old. Apart from the youngest, they had lost mobility at 36-68 years. Most had developed physical problems, in particular in the 4th-6th decade of life: cardiac disease (cardiomyopathy, atrial fibrillations), arthritis, skin blistering, swallowing difficulties requiring feeding by a gastrostomy tube, and seizures. The course of the disease was dominated in most of them by challenging behavioral problems with restlessness, extreme screaming and hitting, difficult to prevent or to treat pharmaceutically. Even in absence of knowledge of the history of an elderly patient with MR, the presence of behavioral problems should prompt metabolic investigation for MPS.
