The different types of atypical development manifest themselves in deviations in the development and operation of neurological functions involved in the process called neurological maturation. We assume that what is called neurological maturation is in effect dependent on the cultural development of homo sapiens. Our culture changes and evolves over time. In the past, the skills and abilities of our hunter-gatherer ancestors with being a mainly oral culture is significantly different from the agricultural, stockbreeder, farmer lifestyle coupled with a mainly written culture. Each of these very distinct cultural styles require different behaviour and cognitive functions. In this article, we discuss how the increased prevalence of learning and control difficulties, along autism, may be a result of the vulnerability of the cerebral functions which from the perspective of human development count as very new. However, this may be only one aspect of a very complex story, as what may present as difficulties in one cultural norm may be strengths in another cultural norm. Many types of the specific learning difficulties, ADHD, autism spectrum disorders are getting more frequent specialties, and their becoming more frequent is the consequence of the effect of the dramatically changing environment on the brain development. While autism and dyslexia spectra seem to be the ends of a continuum, they may be rather a result of a diffused neurological development, where in contrast to the typical development, the culturally new areas are mixed over- or under-functioning.
