Why autism ratio is greater in males

 The exact reasons for the higher prevalence of autism spectrum disorder (ASD) in males are still being investigated, but there are several potential explanations.

Biological factors

  • Genetics: ASD is a complex disorder with a strong genetic component. While the exact genes involved are still being identified, it is thought that males may be more susceptible to certain genetic mutations that increase the risk of ASD.
  • Brain structure and function: There are some differences in brain structure and function between males and females with ASD. For example, males with ASD tend to have larger amygdalae, which are involved in processing emotions.
  • Hormones: Androgens, such as testosterone, may play a role in the development of ASD. Males have higher levels of androgens than females, which could contribute to the higher prevalence of ASD in males.

Diagnostic factors

  • Diagnostic bias: It is possible that males are more likely to be diagnosed with ASD than females because they tend to exhibit more stereotypically autistic behaviors. For example, males with ASD may be more likely to have repetitive behaviors and restricted interests.
  • Gender socialization: Society's expectations for how boys and girls should behave may make it more difficult for females with ASD to be identified. Girls with ASD may be better at masking their symptoms, or their symptoms may be mistaken for other conditions, such as anxiety or attention deficit hyperactivity disorder (ADHD).

Other factors

  • Environmental factors: It is possible that environmental factors, such as exposure to pollution or prenatal infections, could play a role in the development of ASD. However, more research is needed to confirm this.

It is important to note that these are just potential explanations for the higher prevalence of ASD in males. The exact reasons for the sex ratio are still being investigated.

ADAPTIVE BEHAVIOR ASSESSMENT SCALE (ABAS-II)

what is ABAS? The adaptive behavior assessment system (ABAS-II) provides a comprehensive norm-referenced assessment of adaptive skills for individual’s age birth to 89 years. The ABAS-II can be used to assess an individual’s adaptive skills for assessment and diagnosis and classification of disabilities and disorders, identification of strengths and limitations, and to document and monitor an individual’s progress over time. The ABAS-II measures ranges of adaptive skills according to American Association on Mental Retardation (AMAR) and Diagnostic and Statistical Manual of Mental Disorders- Fourth Edition (DSM-IV). It is a complete assessment tool to measure multiple respondents, evaluating functioning across multiple settings and to assessment of daily functioning’s of an individual. The basic components of ABAS-II include the manual and five rating forms. Relevant respondents of the person being evaluated can rate these forms. Respondents can be parents, teachers, family membe...

what is Dyslexia screening test junior and how to apply it?

    THE DYSLEXIA SCREENING TEST Junior (6years 6months to 11years 5months) Introduction The revised Dyslexia Screening Test now covers primary and secondary school-aged children in two separate assessments. The division of the DST into two tests, DST - Junior and DST - Secondary, include extra subtests which are particularly relevant to the age group. The DST-J provides a profile of strengths and weaknesses which can be used to guide the development of in-school support for the child. New theoretical developments in dyslexia research suggest that it should be possible to identify both slow learners and potential dyslexic children at the age of 5 or 6 years, in time for greater reading support. The DST-J is designed for early identification of children who are at risk of reading failure so that they can be given extra support at school . What is dyslexia?? It can be defined as difficulty in learning, reading, or interpreting words, letter, other ...

what is beck hopeless scale?

 Back hopelessness Scale INTRODUCTION Background and development The back hopelessness scale(BHS; Beck’ weissman, lester, &trexler, 1974) IS A 20 item scale for measuring the extent of negative attitude about the future (pessimism)as perceived by adolescents and adult.
