Early detection of reading problems is important to prevent an enduring lag in reading skills. We studied the relationship between speed of word recognition (after six months of grade 1 education) and four kindergarten pre-literacy skills: letter knowledge, phonological awareness and naming speed for both digits and letters. Our sample consisted of 178 pupils divided over seven classes. In agreement with the literature, we found that all four kindergarten tests were related to speed of word recognition in grade 1. We also performed a multiple regression analysis with a set of background variables and the four kindergarten tests. The model explained 53% of the variance in speed of word recognition. However, only letter knowledge and naming speed for digits had a significant direct effect. Our conclusion is, nevertheless, that all four kindergarten tests should be used to identify children at risk for reading problems.

AimTo investigate: (a) language difficulties in children with developmental coordination disorder (DCD), and (b) motor difficulties in children with developmental language disorder (DLD).MethodIn this systematic review, PubMed, CINAHL, PsycINFO, and Embase were searched to identify peer-reviewed studies. Two researchers independently identified, screened and evaluated the methodological quality of the included studies following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). For objective (a), we combined the terms: “developmental coordination disorder” AND “language skills” AND “children”. For objective (b) we combined the terms: “developmental language disorder” AND “motor skills” AND “children”.ResultsTen studies on language skills in children with DCD and 34 studies on motor skills in children with DLD are included, most with relatively good methodological quality. The results for language comprehension and production in children with DCD are contradictory, but there is evidence that children with DCD have communication and phonological problems. Evidence for general motor problems in children with DLD is consistent. Studies report problems in balance, locomotor, and fine motor skills in children with DLD. Evidence for aiming and catching skills is inconsistent.InterpretationThe findings of this systematic review highlight the co-occurrence of language impairments in children with DCD and motor impairments in children with DLD. Healthcare professionals involved in the assessment and diagnosis of children with DCD or DLD should be attentive to this co-occurrence. In doing so, children with DCD and DLD can receive optimal interventions to minimize problems in their daily life.

From the introduction: "There are two variants of fronto-temporal dementia: a behavioral variant (behavioral FTD, bvFTD, Neary et al. (1998)), which causes changes in behavior and personality but leaves syntax, phonology and semantics relatively intact, and a variant that causes impairments in the language processing system (Primary Progessive Aphasia, PPA (Gorno-Tempini et al., 2004). PPA can be subdivided into subtypes fluent (fluent but empty speech, comprehension of word meaning is affected / `semantic dementia') and non-fluent (agrammatism, hesitant or labored speech, word finding problems). Some identify logopenic aphasia as a FTD-variant: fluent aphasia with anomia but intact object recognition and underlying word meaning."
