Dyslexia and Dyspraxia: Commentary

Specific impairments and predictive markers for developmental coordination disorder subtypes in children: The importance of multidimensional developmental assessments in cluster analysis

“…Further to this, it is in this group that significantly more frequent ear, nose and throat disorders were observed than in the VSC group, more frequent language delays and more frequent difficulties in reading. This recalls Nicolson [49] and O' Hare & Khalid [23] who have underlined a high risk of reading delay in DCD. Global or axial hypotonia, disorders in spontaneous gestures and the tonic organisation of laterality, and poor left-right integration of bodily spatial orientation (especially in imitation in relation to another person), were all variables that were prominent in this group, reflecting difficulties in the bodily integration of the egocentric axial reference [50].…”

Similarities in Dyspraxia and Autism

“…Also, praxis in autistic children is associated with the social, communicative, and behavioural impairments that describe the disorder. Dyspraxia might be the main symptom of autism or a marker of the neurological defects emerging the condition [11,12].…”

Understanding the ‘Lexia’ in dyslexia: A multidisciplinary team approach to learning disabilities

“…For example, in the Morris et al stud)~ four of the seven reading disability subtypes had a phonological problem, two had problems in language skills, and one had a rate problem. Another selective impairment in dyslexia that has been documented (Catts, 1989) but understudied (McCormick, 2000;Nicholson, 2000) is oral-motor planning problems (apraxia) that may account for the oral reading dysfluency of some dyslexics. Orthographic (visual word form) deficits (Berninger, Abbott, Thomson, & Raskind, 2001;Olson, Wise, & Forsberg, 1994) and problems in forming orthographic-phonological connections (Berninger & Traweek, 1991;Breznitz, in press;Raskind et al, 2000) also have been observed.…”

“…Whether individuals with developmental dyslexia also have selective, subtle impairments in sensory skills such as fast visual processing (Eden, van Meter, Rumsey, Masiog, Woods, & Zeffiro, 1996), and motor skills such as cerebellar fine tuning of motor skills (Nicholson & Fawcett, 1995;Nicholson, 2000), is still being investigated. It is premature to dismiss these possibilities, given the mounting supportive as well as occasional conflicting evidence (Skottun & Parke, 1999).…”
