Dyslexia
Also called developmental learning disorder with impairment in reading (ICD-11 6A03.0); 'specific learning difficulty' in UK education paperwork. That is the name used in diagnostic manuals and on most official paperwork.
Dyslexia is a common learning difference that mainly affects reading and spelling. It does not affect how clever a child is.
