    Learning difficulties is a broad term used for different conditions that affect the normal learning ability of individuals (Burt, 2004, p. 786).

    Read codes and ICD-10 definition

    These definitions have been previously published in peer-reviewed journals (John et al, 2022).

    SNOMED CT definition

    This definition has been created from mapped Read codes and ICD-10 definitions, as well as an additional exploration of SNOMED CT codes. It includes codes referring to acquired learning difficulties, as well as codes for aphasia and dysphasia.
