This presentation describes the case of a 17 year old female athlete who suffered two consecutive concussions, producing post-concussion headache symptoms. The athlete was assessed following the initial concussion with quantitative EEG (QEEG) and an integrated visual and auditory continuous performance test (IVA). 22 sessions of QEEG-guided neurofeedback produced normalisation of the QEEG and IVA profiles, and a cessation of headaches. A second concussion then produced further abnormalities in the QEEG and the IVA. A final course of 40 sessions of neurofeedback was again successful in normalising both cortical activity on the QEEG and scores on the IVA.
