Retrospective parental assessment of childhood neurodevelopmental problems: the use of the Five to Fifteen questionnaire in adults.

Background: Attention-deficit hyperactivity disorder and autism are increasingly recognised in adults. For a diagnostic evaluation, parental information on childhood development is needed. However, no instruments that retrospectively describe neurodevelopmental problems in childhood are validated for evaluating adults.

Asperger Syndrome and Schizophrenia: A Comparative Neuropsychological Study.

There has been an increasing interest in possible connections between autism spectrum disorder (ASD) and schizophrenia in the last decade. Neuropsychological comparison studies have, however, been few. The present study examined similarities and differences in intellectual and executive functioning between adults with Asperger syndrome (AS) and adults with schizophrenic psychosis (SP).

Asperger syndrome and schizophrenia: Overlap of self-reported autistic traits using the Autism-spectrum Quotient (AQ).

Background: In clinical practice, the differential diagnosis of Asperger syndrome (AS) versus schizophrenia can be a challenge. Some self-report instruments-such as the Autism-spectrum Quotient (AQ)-have been portrayed as proxies for the diagnosis of AS. However, it has not been demonstrated to what extent autistic traits-as measured by the AQ-separate AS from schizophrenia.

Social cognition impairments in Asperger syndrome and schizophrenia.

Social cognition impairments are well described in both autism spectrum disorders, including Asperger syndrome (AS), and in schizophrenia spectrum disorders. However, little is known about whether there are differences between the two groups of disorders regarding this ability. The aim of this study was to compare social cognition abilities in AS and schizophrenia.

ADHD and nicotine use in schizophrenia or Asperger syndrome: a controlled study.

Objective: To examine ADHD prevalence, rating scales, and relationship to nicotine use in adults with schizophrenia or Asperger syndrome.

Method: Ninety-five individuals, 41 with schizophrenia and 54 with Asperger syndrome, were included. Self-rating of adult ADHD symptoms with the Wender-Reimherr Adult Attention Deficit Diagnostic Rating Scale (WRAADDS), parent rating of proband's ADHD childhood and adult life symptoms using the Swanson, Nolan, and Pelham Questionnaire (SNAP), and report of clinical ADHD diagnosis were included as ADHD measures.

Is autism spectrum disorder common in schizophrenia?

A century ago, Kraepelin and Bleuler observed that schizophrenia is often antedated by "premorbid" abnormalities. In this study we explore how the childhood neurodevelopmental problems found in patients with schizophrenia relate to the current concept of autism spectrum disorder (ASD). Forty-six young adult individuals with clinical diagnoses of schizophrenic psychotic disorders were assessed.

Personality disorders and autism spectrum disorders: what are the connections?

Background: The relationship between autism spectrum disorders/pervasive developmental disorders and personality disorders is not completely clear, although both concepts imply lifelong impairment. The purpose of the present study was to investigate the presence of possible personality disorders in a group of young adults with Asperger syndrome.

Method: Fifty-four young adults with a clinical diagnosis of Asperger syndrome were assessed with Structured Clinical Interview for DSM-IV Axis II disorders to evaluate the presence of a concomitant personality disorder and completed the Autism Spectrum Quotient to measure level of autistic features.

Psychiatric comorbidity in young adults with a clinical diagnosis of Asperger syndrome.

In children with autism spectrum disorders, previous studies have shown high rates of psychiatric comorbidity. To date, studies on adults have been scarce. The aim of the present study was to investigate psychiatric comorbidity in young adults with Asperger syndrome.

The Reading the Mind in the Eyes Test: test-retest reliability of a Swedish version.

Introduction: The Reading the Mind in the Eyes Test is a widely used facial affect recognition test. The present study aimed to provide Swedish nonpatient reference values, examine test-retest reliability, and to elucidate strengths and weaknesses of the instrument.

Methods: A Swedish version of the test was completed by 158 university students.
