Motor Incoordination In aSample of Preschool Children with Attention Deficit Hyperactivity Disorder
Moatazbellah Ibrahim Mohamed Ali;
Abstract
Attention deficit hyperactivity disorder(ADHD) is a highly heritable neurodevelopmental disorder. It is one of the most prevalent psychiatric disorders in children and it greatly impairs social and cognitive functions in affected individuals. It is characterized by a childhood-onset pattern of hyperactivity, inattention and impulsivity, that commences in early childhood and often persists into adulthood.
The current psychiatric disease classification system, DSM-5, distinguishes three subtypes: a mainly inattentive, a mainly hyperactive–impulsive and a combined subtype
ADHD occurs in 8-12% of children worldwide and is more prevalent in males than females. ADHD’s onset occurs around 3 years of age in both sexes. ADHD symptoms usually lessen with age such that the rate of persistence is only 15% by age 25.
Common comorbidities in children with ADHD includemotor coordination problems, tic disorders, sleep disorders, specific learning disorders such as dyslexia, and child-psychiatric disorders such as depression, anxiety, oppositional defiant and conduct disorders, and autistic spectrum disorders.
ADHD is best seen as a multifactorial disorder in which genes and environmentplay a complicated intertwined role. Multifactorial in this respect implies that the phenotype is due to the combination of multiple genetic as well as environmental contributors
Children generally develop an amazing number of motor skills in the first years of their lives. Some of these skills, such as walking, develop naturally, whereas other skills, such as swimming and writing require a lot of practice after specific instruction.
Developmental coordination disorder (DCD) is a marked impairment in motor coordination which significantly interferes with academic achievement or activities of daily living. These deficits in motor skills have been labelled in many ways over the centuries (e.g.,neurological soft signs, clumsiness), but the current, dominant term is developmental coordination disorder in young children is more common than generally realized. Children under the age of 5 years may have difficulties in one or more areas of development,including speech and language, motor, social-emotional and cognitive development.
