There is a significant level of misdiagnosis of autism in neurodevelopmentally typical children; 18–37% of children diagnosed with ASD eventually lose their diagnosis. This high rate of lost diagnosis cannot be accounted for by successful ASD treatment alone.
Overall, they found that females diagnosed with autism or another neurodevelopmental disorder had a greater number of harmful mutations throughout the genome than did males with the same disorders. [20] Women with an extra X chromosome, 47,XXX or triple X syndrome, have autism-like social impairments in 32% of cases. [21]
A 2022 study in the “Children” journal concluded that the true female ratio could be 3 men to every 4 women, and that 80 percent of females remain undiagnosed with autism at the start of ...
Prevalence differences may be a result of gender differences in expression of clinical symptoms, with women and girls with autism showing less atypical behaviors and, therefore, less likely to receive an ASD diagnosis. [367] Using DSM-5 criteria, 92% of the children diagnosed per DSM-IV with one of the disorders which is considered part of ASD ...

Unusual responses to sensory stimuli are more common and prominent in individuals with autism, and sensory abnormalities are commonly recognized as diagnostic criteria in autism spectrum disorder (ASD), as reported in the DSM-5; although there is no good evidence that sensory symptoms differentiate autism from other developmental disorders.

The Ritvo Autism & Asperger Diagnostic Scale (RAADS) is a psychological self-rating scale developed by Riva Ariella Ritvo (NPI UCLA and CSC Yale). An abridged and translated 14 question version was then developed at the Department of Clinical Neuroscience at the Karolinska Institute, to aid in the identification of patients who may have undiagnosed ASD.
Males are diagnosed with ASD four to five times more often than females. [6] [7] The reasons for this remain predominantly unclear, but current hypotheses include a higher testosterone level in utero, different presentations of symptoms in females (leading to misdiagnosis or underdiagnosis) compared to males, and gender bias.
