•Magnetization transfer MRI was used in a cohort of 40 MS subjects differing by age.•MTR metrics were different between MS groups and controls, as expected.•MTR in normal appearing tissue did not differ between age-stratified MS groups.•MTR in white matter lesions was strongly different between age-stratified MS groups.•Results imply an age-related effect in tissue integrity in MR-visible lesions.
