Neurocognitive and Psychosocial Outcome of Youths With Autism Spectrum Disorder

1. september 2021 oppdatert av: National Taiwan University Hospital

Neurocognitive and Psychosocial Outcome of Youths With Autism Spectrum Disorder: a Follow-up Study

Autism spectrum disorders (ASD) is a common childhood-onset, multi-factorial, highly heritable, clinically and genetically heterogeneous, neurodevelopmental disorder. Due to its high prevalence and severe lifelong impairment without effective prevention and treatment, there is a dearth of investigating its pathogenesis, longitudinal outcome, and biomarkers (endophenotypes). The ultimate goals of this 5-year project are to prospectively investigate the outcome and changes of psychosocial and neurocognitive functions of a cohort of probands with ASD at adolescence and young adulthood as the primary aim; and to test whether structural and functional brain connectivity can be effective endophenotypes of ASD using the unaffected sibling and follow-up designs as the secondary aims.

Primary Aim:

To investigate the neuropsychological, neuroimaging, social cognitive, and psychosocial outcomes at adolescence and young adulthood among children with ASD as compared to typically developing (TD) controls.

Secondary Aims:

  1. To examine the changes and stability of ASD core symptoms, neuropsychological function, structured and functional connectivity, psychosocial functions over a 4-7 year follow-up period.
  2. To identify early individual (clinical, behavioral, and neurocognitive variables), family, school, environmental factors to predict the neurocognitive and psychosocial outcomes at adolescence and young adulthood.
  3. To validate the neuropsychological functioning (e.g., set-shifting, executive function, and visuo-spatial memory etc.) and structural (morphometric,, cortical thickness, gyrification, white matter tract integrity) and functional connectivity (resting-state and social task fMRI) in fronto-temporal, cortico-striato-thalamic, default mode network, and other circuits as effective imaging endophenotypes (biomarkers) by demonstrating the stability of these imaging data and the intermediate position of unaffected siblings between ASD probands and age-, sex-, handedness-, and IQ-matched TD at Time 1 and follow-up.
  4. To correlate the data from structural and functional connectivity, neuropsychology and ASD core symptoms stratifying by proband-unaffected sibling dyads, and different developmental stages.
  5. To collect blood sample, and to analyze neurodevelopmental and immune genes, cytokine level, and environmental exposure.

Studiepopulasjon

373 ASD, aged 10-25, from the cohort of ASD established by NRPGM, who consented to this follow-up study at their first assessments in 2007-2011 and 150 age-, and sex-matched TD, at the ratio of 2:1.

Beskrivelse

Inclusion Criteria:

ASD participants

  1. that they have a clinical diagnosis of autistic disorder or Asperger disorder defined by the DSM-IV and ICD-10 criteria, made by board-certificated child psychiatrists and who were clinically diagnosed with ASD confirmed by the ADI-R 7 years ago;
  2. their ages range from 10 to 25 (i.e., 3-18 years old at the first assessment);
  3. both parents are Han Chinese;
  4. who have complete clinical and behavioral data at the 1st assessment;
  5. participants and their parents consented to participate in this longitudinal study 7 years ago for complete assessments (3 visits of assessments) at follow-up.

Inclusion Criteria for TD controls, who will be recruited either by school teachers or from the community, are that they are Han Chinese, consent to the study (if age <18, parents, too) to complete all the assessments.

Exclusion Criteria:

For TD controls:

  1. comorbidity with DSM-IV-TR or DSM-5 diagnoses of ASD, ADHD, schizophrenia, schizoaffective disorder, delusional disorder, other psychotic disorder, organic psychosis, schizotypal personality disorder, bipolar disorder, depression, severe anxiety disorders or substance use;
  2. comorbidity with neurological or systemic disorders; and
  3. having a first degree relative who may have ASD based on family history method assessment.
