Dyspraxia is defined as a neuro cognitive developmental disorder mainly involving the development of the gesture. If it is now well recognized thanks to the consensus on diagnostical criteria [1Blank R (EACD). Recommendations on the definition, diagnosis and intervention of developmental coordination disorder DMCN 2012 ;  54 : 54-93 [cross-ref]

The heterogeneous symptomatology, the frequency of the associated motor and cognitive disorders primarily focusing on the language, the attention and the executive functions, the evolution of the symptomatology over time make it a complex pathology with little reliable prognosis in the adulthood. It is, however, a frequently raised question by the parents, as soon as the diagnosis is assessed during the childhood: “what future for her or him when growing?” In order to answer this question, it seems important to develop, in this domain, case studies with longitudinal follow up. It is probably a way to assess a neuro cognitive developmental model of the function by studying several individual trajectories taking into account the change of the different components of the praxic function as well as other cognitive functions involved and their evolution as time goes on. Of course the effect of rehabilitations has to be taken into consideration as well as the difficulty in making a difference between natural evolution and what depends of the evolution modified by treatments. Currently, the reference hospital centers for language and learning disorders since the promulgation in March, 2001 of the action plan for the children with specific language disorder can follow-up these children in partnership with the liberal professionals and/or establishments of the medical and social sector as well as the Education system. Today, it is, thus, possible to lean on their experience, their expertise and their capacity to coordinate care with their partners in order to carry on such studies. To illustrate this approach, we shall present, here, several clinical situations.
