Behavioural results (N = 740). (A) The chart represents the distribution of performances for writing words (blue) and numbers (orange). (B) Pie charts representing the prevalence of writing impairments. The pie chart on the left, green represent patients who show no impairment in writing, blue represents patients who show impairment in at least one of the writing task. The pie chart on the right, break the blue group, to those how show impairment on both writing tasks (orange), or just on one of them (yellow, grey). (C) pie charts that break comorbidities in patients who show deficits in both writing tasks (the orange group) based on the prevalence of comorbidity with the language-based (left) and motor-based (right) tasks. *Deficit in most tasks (ii:3 language tasks; iii: 2 motor tasks); deficit in some tasks (ii: 1 or 2 language tasks; iii:1 motor task).
