13 conditions in the Repatriation Medical Authority's Statements of Principles list concussion as a factor. If DVA has accepted your concussion, each of these has a documented pathway to a further claim.
Some Statement of Principles factors are not about service at all — they name another condition. Where DVA has already accepted your concussion, and another condition's SoP lists concussion as a factor, that part of the next claim is already established on your file. How a secondary claim works, in full →
Quoted from the instrument. A pathway existing is not the same as a claim succeeding — each factor carries thresholds your record has to satisfy.

If any of these is also on your file, it reaches some of the same conditions concussion does.
A claim is tested against the definition first. If the diagnosis on your file does not meet this wording, the factors below never get reached — so it is worth checking that what your doctor wrote matches what the instrument requires.
Concussion, for the purposes of the Statement of Principles, for the purposes of this Statement of Principles, concussion: (a) means a mild traumatic brain injury resulting from the transfer of kinetic energy to the brain from external physical forces, which is manifested by a temporary disturbance in neurological function that does not meet the criteria for moderate to severe traumatic brain injury; and (b) excludes injury from radiation, electricity, heat and surgery.
Note the exclusion. This instrument expressly excludes injury from radiation, electricity, heat and surgery. A diagnosis of that is not a diagnosis of concussion, and a claim framed the wrong way fails on the definition before any factor is considered.
Aggravation-only factors. In this instrument, subsections 9(2) apply only to material contribution to, or aggravation of, concussion where it was already present before or during service. If service caused concussion outright, those factors are not available to you.
