Handwriting in children with Attention Deficient Hyperactive Disorder: role of graphology

Abstract

BackgroundHandwriting difficulties are common in children with attention deficient hyperactive disorder (ADHD). The aim of our study was to find distinctive characteristics of handwriting in children with ADHD by using graphology to analyze physical characteristics and patterns, and to evaluate whether graphological analysis is an effective ADHD diagnostic tool for clinicians.MethodThe cohort included 49 children aged 13–18 years attending a tertiary neurology and epilepsy center in 2016–2017; 22 had a previous DSM-IV/V diagnosis of ADHD. The children were asked to write a 10–12-line story in Hebrew on a blank sheet of paper with a blue pen over a 20-min period. The samples were analyzed by a licensed graphologist blinded to the clinical details of the children against a predetermined handwriting profile of individuals with ADHD. Each ADHD characteristic identified in each sample was accorded 1 point, up to a total of 15 points. Patients with a graphology score of 9–15 were considered to have ADHD.ResultsThere were 21 boys (43%) and 28 girls (57%) in the cohort; 15 boys (71.4%) and 7 girls (25%) had a DSM-IV/V diagnosis of ADHD. The mean graphology score was significantly higher in the children who had a DSM-IV/V diagnosis of ADHD than in the children who did not (9.61 + 3.49 vs. 5.79 + 4.01, p = 0.002, respectfully). Using a score of 9 as the cutoff, in the girls, graphology had a specificity of 80% (95% CI 59.2–92.8) and a of sensitivity 71.4% for predicting ADHD. Corresponding values in the boys were 75.0 and 76.2%.ConclusionThe handwriting of children with ADHD has specific characteristics. Graphology may serve as a clinically useful tool in the diagnosis of ADHD.

How effective is fine motor training in children with ADHD? A scoping review

“…General or fine motor impairments are reported across countries in Australian [ 18 , 25 ], Iranian [ 33 ], South African [ 46 ], Dutch [ 16 , 52 ] Brazilian [ 8 , 22 ] and Taiwanese children [ 24 ], to name just a few examples. Handwriting impairments are observed independently of the written or spoken language in English, Chinese [ 38 , 41 ], Hebrew [ 36 , 53 ] and Japanese handwriting [ 48 ]. Poorer handwriting legibility and speed were observed both in Anglophone and Francophone Canadian children with the latter showing greater speed only in one handwriting subtest [ 47 ].…”

A Smart Ink Pen for the Ecological Assessment of Age-Related Changes in Writing and Tremor Features

“…In addition, a technology that allows quantitative, simple, and ecologically valid evaluation of handwriting finds potential and interesting applications also in the youngest population, since handwriting and text production skills assume a central role in the children's development process. In this framework, handwriting difficulties are common in a number of childhood disorders, including, dysgraphia [46]- [47], dystonia [48]- [50], and attention deficient hyperactive disorder [51].…”

Handwriting Analysis in Children and Adolescents with Hemophilia: A Pilot Study

“…Handwriting is an example of an important life skill that, if impaired, can lead to academic challenges or failure and diminished self-esteem [ 6 , 7 , 8 , 9 ]. Although most children are now exposed to computers at an early age, handwriting is still used in classrooms and everyday life.…”

“…As an incurable chronic disease, hemophilia implies a psychological burden both for children and parents that may influence functioning in daily activities [ 5 ]. Handwriting is an example of an important life skill that, if impaired, can lead to academic challenges or failure and diminished self-esteem [ 6 , 7 , 8 , 9 ]. Moreover, handwriting is a complex task that requires the integrity of different sensorimotor components to be performed successfully.…”
