“…With respect to study populations, it is essential that in studies involving a mixture of ID and non-ID patients, separate prevalence estimates are made, given the sizeable disparity in ASD prevalence estimates between this groups in community-based prevalence studies [7, 8, 4, 3]. As a result, the meaningfulness of prevalence estimate for a mixed ID/non-ID study populations is limited, unless separate data for both groups is also reported.…”

“…Community-based prevalence rates for autism in the general population show considerable variation across studies, though recent systematic reviews and large-scale epidemiological research estimate rates of between 0.7-1.1% [7, 8]. Additionally, the prevalence of autism is significantly higher in people with moderate to profound intellectual disability (ID); Brugha et al [8] found a prevalence of 39.3% (95% confidence interval 31.0-48.4) for this patient group, compared to 1.0% (95% confidence interval 0.4-2.2) for those with mild ID.…”

For these reasons, ASD represents a major global public health issue, responsible for over 111 Disability Adjusted Life Years (DALY’s) per 100,000 persons [7].…”

Background:Whilst the prevalence of autism spectrum disorders in adults within the community setting is well-established, less is known about the prevalence among adults based within a psychiatric inpatient setting.Objective:To conduct a systematic literature review pertaining to the prevalence of autism spectrum disorders among the adult psychiatric inpatient population.Method:Eligibility criteria included: (a) investigation of the prevalence of autism spectrum disorders (b) adult psychiatric inpatient study population (c) published in English language. Electronic databases accessed included PubMed, Medline, CINAHL, PsycINFO and EMBASE. Additionally, the ancestry method was utilised for the references of eligible papers, as well as grey literature searches and consultation with experts in the field.Results:From the search, 4 studies were identified which satisfied the inclusion criteria, conducted in a variety of inpatient psychiatric settings, including secure forensic and intellectual disability units and a state psychiatric hospital. There were significant differences in methodological approaches, including the screening tests, diagnostic instruments and diagnostic criteria utilised. Autism spectrum disorder prevalence estimates varied considerably, from 2.4-9.9%.Conclusion:From the limited research data currently available, it appears that the prevalence of autism spectrum disorders is increased in inpatient psychiatric settings relative to the general population. There is a need for further high quality research in this patient group, to add to this limited evidence base, as well as in developing effective strategies to identify patients with a high likelihood of autism spectrum disorders within this setting.

“…In Great Britain, the prevalence of ASDs Open Journal of Psychiatry in childhood is approximately 1% of the population [8], whereas in adulthood the prevalence increases to 1.1% [9]. In the United States, a recent research pointed out a prevalence of 2.41% [10].…”

Background: In Italy, there is a lack of reliable data on the epidemiology of Autism Spectrum Disorder (ASD) on a national scale. The exact etiopathogenesis of ASDs is still largely unknown, with autism representing the final common pathway of different pathological conditions. Aim of the Study: Assessment of the effects produced by the individualised, intensive and holistic rehabilitation programme used by the Il Cireneo Foundation on the daily living skills of people diagnosed with ASD. Materials and Methods: Out of the eighty-seven (n = 87) enrolees, seventy-nine (n = 79), of whom 19 were females (24.1%) and 60 were males (75.9%), with a mean age of 13.41 years (SD = 6.93 years; range = 2 -33 years) terminated the three-year study. The enrolees were evaluated two times: at the beginning of the rehabilitation programme and at the end of the three-year goal-oriented project. Results: Statistically significant results between T0 and T1 were recorded for CARS (t-4.221; p < 0.05) and for the domains of Communication (t-2.750; p < 0.05), Daily Living Skills (t-6.526; p < 0.05) and Motor Skills (t-3.524; p < 0.05) of the VABS. Conclusions: People diagnosed with autism can be helped to become more autonomous and independent in carrying out activities of daily living thanks to an intensive psycho-educational and cognitive-behavioural rehabilitation programme, of which the Il Cireneo Foundation is the only expression in the Abruzzo region.

“…Although there is also a change in the concept, there is a possibility that the prevalence of ASD in Japan is increasing. The prevalence of ASD in adults was first reported in the U.K in 2007 as approximately 1% of the population [4,8] though it is believed that many potential ASD patients remain undiagnosed and the comorbidities (secondary disorders) remain untreated. The prevalence of adult ASD in Japan has not been reported yet.…”

Epidemiology of autism in adults across age groups and ability levels

Abstract: Few adults with autism have intellectual disability; however, autism is more prevalent in this population. Autism measures may miss more women with autism.
