Screening for Studies on Autism Spectrum Disorders

2014-08-27 03:46:56 | BioPortfolio

Summary

This study will screen children and adolescents (and their parents) to determine the child's eligibility for participation in NIMH research studies on autism spectrum disorders, such as autism and Rett's Disorder.

Screening evaluations include some or all of the following procedures:

Parent interview

Parent and child evaluations including:

- Diagnostic interview

- Developmental or cognitive testing

- Ratings of psychiatric and medical symptoms

- Neuropsychological testing

- Personal, social an family history

Child physical examination and possible blood draw

Children who are determined eligible for a current NIMH research protocol are invited to participate.

Description

The purpose of this protocol is to allow for the careful evaluation of healthy volunteers and individuals with psychiatric disorders or neurodevelopmental disorders, such as autism spectrum disorders. The evaluations will help determine if the participant meets criteria for participation in research protocols of the Pediatric and Developmental Neuropscience Branch (PDN) at the National Institute of Mental Health (NIMH) and other collaborative investigations. This protocol will be the entry point for all PDN investigations. Since the entry criteria for these protocols vary, the screening evaluations will also vary. Behavioral evaluations will also be done through this protocol for individuals participating in IRB-approved protocols being conducted by collaborating scientists in NIH. The evaluations might include: a psychiatric interview; a diagnostic interview; developmental and/or cognitive testing; ratings of other psychiatric symptoms; neuropsychological testing; a medical history; a physical exam; blood; and a request for medical records. Parents of minors will be interviewed. Upon conclusion of the screening process, subjects seeking eligibility for PDN protocols will either be offered participation in a research protocol and will sign the appropriate informed consent, or will be considered not appropriate for participation in research and will be discharged from the protocol.

Medical and Biotech [MESH] Definitions

Wide continuum of associated cognitive and neurobehavioral disorders, including, but not limited to, three core-defining features: impairments in socialization, impairments in verbal and nonverbal communication, and restricted and repetitive patterns of behaviors. (from DSM-V)

A childhood disorder predominately affecting boys and similar to autism (AUTISTIC DISORDER). It is characterized by severe, sustained, clinically significant impairment of social interaction, and restricted repetitive and stereotyped patterns of behavior. In contrast to autism, there are no clinically significant delays in language or cognitive development. (From DSM-IV)

These disorders are related to both SCHIZOPHRENIA SPECTRUM AND RELATED DISORDERS and DEPRESSIVE DISORDERS in terms of symptomatology, family history, and genetics. (DSM-V) .

Disorders comprising a spectrum of brain malformations representing the paradigm of a diffuse neuronal migration disorder. They result in cognitive impairment; SEIZURES; and HYPOTONIA or spasticity. Mutations of two genes, LIS1, the gene for the non-catalytic subunit of PLATELET-ACTIVATING FACTOR ACETYLHYDROLASE IB; and DCX or XLIS, the gene for doublecortin, have been identified as the most common causes of disorders in this spectrum. Additional variants of classical (Type I) lissencephaly have been linked to RELN, the gene for reelin, and ARX, the gene for aristaless related homeobox protein. (From Leventer, R.J., et al, Mol Med Today. 2000 Jul;6(7):277-84 and Barkovich, A.J., et al, Neurology. 2005 Dec 27;65(12):1873-87.)

Marked disorders of thought (delusions, hallucinations, or other thought disorder accompanied by disordered affect or behavior), and deterioration from a previous level of functioning. Individuals have one o more of the following symptoms: delusions, hallucinations, and disorganized speech. (from DSM-5)
