“…Research has demonstrated that at the age of 6 months behavior of children later diagnosed with ASD is similar to that of typically developing children [ 50 , 118 , 119 ]. ASD’s signs of impaired social interaction and communication slowly emerge in the second half of the first postnatal year to become more evident in the beginning of the second year [ 50 , 119 , 120 , 121 ]. With increasing age the majority of children with ASD gradually loose social and communicative abilities that they had mastered previously [ 119 ].…”

“…With increasing age the majority of children with ASD gradually loose social and communicative abilities that they had mastered previously [ 119 ]. Examples of specific early signs are deficits in joint attention, gazing at faces and orienting to their name being called [ 50 , 118 , 121 ]. An unspecific sign of ASD in infancy is atypical emotionality and self-regulation [ 88 , 122 ].…”

“…The literature on ASD indicates that it is hard to detect ASD in the first postnatal year. The first signs of ASD slowly emerge in the second half of the first year, in particular from 9 months onwards [ 119 , 121 ]. The time of emergence corresponds to the age at which the temporal structures of the subplate in the association areas, including the prefrontal and the parieto-temporal regions, and the external granular layer in the cerebellum have disappeared.…”

This review discusses early diagnostics and early intervention in developmental disorders in the light of brain development. The best instruments for early detection of cerebral palsy (CP) with or without intellectual disability are neonatal magnetic resonance imaging, general movements assessment at 2–4 months and from 2–4 months onwards, the Hammersmith Infant Neurological Examination and Standardized Infant NeuroDevelopmental Assessment. Early detection of autism spectrum disorders (ASD) is difficult; its first signs emerge at the end of the first year. Prediction with the Modified Checklist for Autism in Toddlers and Infant Toddler Checklist is possible to some extent and improves during the second year, especially in children at familial risk of ASD. Thus, prediction improves substantially when transient brain structures have been replaced by permanent circuitries. At around 3 months the cortical subplate has dissolved in primary motor and sensory cortices; around 12 months the cortical subplate in prefrontal and parieto-temporal cortices and cerebellar external granular layer have disappeared. This review stresses that families are pivotal in early intervention. It summarizes evidence on the effectiveness of early intervention in medically fragile neonates, infants at low to moderate risk, infants with or at high risk of CP and with or at high risk of ASD.

“…Regression is understood in AIM as the final point of a pre-encephalopathy process. The pathway to chronicity is considered to be an individual process and not a single event [63] and the final point could be considered to be the regression. The chronic status of the encephalopathy would be related to chronic pathophysiological processes in the brain in ASD (see reference [52] for further explanation).…”

The rationale of an Advanced Integrative Model and an Advanced Integrative Approach is presented. In the context of Allopathic Medicine, this model introduces the evaluation, clinical exploration, diagnosis, and treatment of concomitant medical problems to the diagnosis of Autism Spectrum Disorder. These may be outside or inside the brain. The concepts of static or chronic, dynamic encephalopathy and condition for Autism Spectrum Disorder are defined in this model, which looks at the response to the treatments of concomitant medical problemsto the diagnosis of Autism Spectrum Disorder. (1) Background: Antecedents and rationale of an Advanced Integrative Model and of an Advanced Integrative Approach are presented; (2) Methods: Concomitant medical problems to the diagnosis of Autism Spectrum Disorder and a discussion of the known responses of their treatments are presented; (3) Results: Groups in Autism are defined and explained, related to the responses of the treatments of the concomitant medical problems to ASD and (4) Conclusions: The analysis in the framework of an Advanced Integrative Model of three groups including the concepts of static encephalopathy; chronic, dynamic encephalopathy and condition for Autism Spectrum Disorder explains findings in the field, previously not understood.

“…This special issue includes four studies (Hatch et al 2020;Lorenzo et al 2020;Stenberg et al 2020;Tanner and Dounavi 2020) that provide new insight on early emerging symptoms. This is a critical area of investigation because the age of diagnosis in epidemiological samples is still 3-5 years of age (Baio et al 2018;Fountain et al 2011;Mandell et al 2010;Shaw et al 2020).…”

Early identification of autism spectrum disorder (ASD) is considered by most scholars and clinicians to be a feasible and useful step for improving the wellbeing of individuals on the autism spectrum and their families. Arguments supporting early detection efforts include the benefit of earlier access to services providing autism-specific evidence-based interventions (Vivanti et al., Journal of Autism and Developmental Disorders, 46(7), 2441–2449, 2016; Zwaigenbaum et al., Pediatrics, 136(Suppl), S10–S40, 2015), and its potential to mitigate or even prevent the challenges associated with ASD symptoms, reduce care costs, and improve the quality of life and productivity of individuals with ASD (Constantino et al., Pediatrics, 146(3), e20193629, 2020; Jacobson et al., Behavioral Interventions, 13(4), 201–226, 1998; Jacobson and Mulick, Journal of Autism and Developmental Disorders, 30(6), 585–593, 2000). Nevertheless, controversies and challenges in this field exist.
