After lowering the gear on final to Runway XXR in ZZZ; we received an ECAM stating that the auto brake system was inoperative. We accomplished the ECAM procedure and consulted the QRH; which stated that the normal brakes were inoperative also. I chose to go around because of the short runway and immediately asked for a diversion to ZZZ; which was our designated alternate. Passing through 2;000 feet; a Flight Attendant notified us that a passenger was having a seizure. We notified Dispatch and coordinated with ATC and ZZZ1 Operations; requesting paramedics to meet us at the gate. Things were very hectic during the 10 minute flight; but the First Officer and I worked well together.
A320 Captain reported that a brake system failure and a passenger medical emergency resulted in a diversion.
