Previous studies have found a subgroup of people with autism or Asperger Syndrome who pass second-order tests of theory of mind. However, such tests have a ceiling in developmental terms corresponding to a mental age of about 6 years. It is therefore impossible to say if such individuals are intact or impaired in their theory of mind skills. We report the performance of very high functioning adults with autism or Asperger Syndrome on an adult test of theory of mind ability. The task involved inferring the mental state of a person just from the information in photographs of a person's eyes. Relative to age-matched normal controls and a clinical control group (adults with Tourette Syndrome), the group with autism and Asperger Syndrome were significantly impaired on this task. The autism and Asperger Syndrome sample was also impaired on Happé's strange stories tasks. In contrast, they were unimpaired on two control tasks: recognising gender from the eye region of the face, and recognising basic emotions from the whole face. This provides evidence for subtle mindreading deficits in very high functioning individuals on the autistic continuum.

Obsessive-compulsive disorder (OCD) in young people is underrecognized and undertreated. Simple screening tools suitable for general practice and community services are needed. We created a seven-item self-report Short OCD Screener (SOCS) and administered itto young people aged 11-15 years, including 116 patients with OCD, 181 healthy community controls and 33 young people with other psychiatric diagnoses. The SOCS has excellent sensitivity of 0.97 (95% CI 0.91-0.98) to detect OCD cases. Its specificity is good in children without psychiatric diagnoses, but low in a psychiatric sample. The SOCS is a screening tool suitable for community but not specialist settings.

The effect of gabapentin on cognition and quality of life (QoL) in patients with epilepsy was investigated using a controlled pre- and post-treatment design. Thirty patients with chronic epilepsy were administered a battery of cognitive tests and QoL measures at baseline (pre-treatment) and again following 1-2 months of treatment (post-treatment). All patients were receiving anticonvulsant medication at baseline. Following baseline assessment, 15 patients were started on gabapentin as add-on therapy (gabapentin group), and 15 patients remained on stable medication (control group). No between-group treatment effects were demonstrated on any of the mood measures. A significant between-group treatment effect was demonstrated on one cognitive measure, in favour of the gabapentin group. Results do not suggest any adverse short-term effects of gabapentin on cognition or QoL in patients with chronic epilepsy.

Thirty-seven pupils attending a special school for children and adolescents with autism were observed for the presence of motor and vocal tics. Subsequent family interviews confirmed the diagnosis of comorbid Gilles de la Tourette's Syndrome (GTS) in three children with autism, giving a minimum prevalence rate of 8.1 %. Family history data also suggested this was heritable. The presence of GTS was not associated with superior intellectual, language, or social development. Results suggest that the rate of GTS in autism may exceed that expected by chance. The limited sample size constrains this conclusion. A large-scale epidemiological study testing this association study would appear merited.
