Despite the overt nature of most motor and phonic tic phenomena, the development of valid and reliable scales to rate tic severity has been an elusive goal. The Yale Global Tic Severity Scale (YGTSS) is a new clinical rating instrument that was designed for use in studies of Tourette's syndrome and other tic disorders. The YGTSS provides an evaluation of(More)
The search for nongenetic factors that mediate the expression of a genetic vulnerability to Tourette's syndrome (TS) is an important undertaking that may provide valuable clues concerning the pathophysiology of this disorder as well as potential treatment approaches. In a direct interview study, the perinatal experiences of 31 TS patients were compiled in(More)
The safety and effectiveness of clonidine hydrochloride (3 to 5 micrograms/kg per day) were evaluated in 47 subjects with Gilles de la Tourette's syndrome, aged 7 to 48 years. Twenty-four subjects were randomly assigned to clonidine treatment and 23 to placebo. Forty subjects (21 given clonidine and 19 placebo) successfully completed the 12-week,(More)
A system proposed by Wing and coworkers for subtyping autistic individuals on the basis of social interaction is examined in 78 autistic, 39 atypical, and 32 nonautistic, developmentally disordered individuals. Clinical ratings and questionnaire data based on the proposed subtypology were employed. Clinicians were able to reliably group both autistic and(More)
Performance on the Wisconsin Card Sorting Test (WCST) is widely reported to be impaired in patients with schizophrenia. It has been hypothesized that the performance deficit on the WCST in schizophrenia is related to a dysfunction of the frontal lobe, specifically the dorsolateral prefrontal cortex. This hypothesis was tested by comparing a group of(More)

BACKGROUND Older patients are at an increased risk of developing adverse drug reactions (ADR). Of particular concern are the oldest old, which constitute an increasingly growing population. Having a validated clinical tool to identify those older patients at risk of developing an ADR during hospital stay would enable healthcare staff to put measures in(More)
Adverse drug reaction (ADR) risk-prediction models for use in older adults have been developed, but it is not clear if they are suitable for use in clinical practice. This systematic review aimed to identify and investigate the quality of validated ADR risk-prediction models for use in older adults. Standard computerized databases, the gray literature,(More)
In all, 1872 children were recruited as part of a larger study concerning food additives and behaviours in preschool children. This figure represented 70% of the whole population of 3 1/4 -year-old children resident on the Isle of Wight, UK. Parents completed an assessment concerning their perceptions of their child's behaviour. The results of this(More)
