Answer: (1) or (4) neurodevelopmental disorder / learning disability
Dysgraphia is a specific learning disability in writing: poor handwriting, uneven spacing, spelling errors and trouble putting thoughts on paper, despite normal intelligence.
Specific learning disabilities are themselves classed among neurodevelopmental disorders, since they arise from differences in how the brain develops and processes information.
So both labels fit; (4) is the precise classroom term, (1) the wider category.
It is neither a personality disorder nor a physical disability.
