Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, whether he plans to (a) collect and (b) publish data on the number of people whose work capability is affected by (i) migraine and (ii) related headache disorders.

The Department does collect data on people whose work capability is affected by (i) migraine and (ii) related headache disorders. We publish WCA health conditions outcomes data by ICD10 summary groups because people may have multiple conditions within each summary group. Therefore, only the summary group is retained for publication purposes.
