Narrative:

During descent into ZZZ at approximately FL180; the cockpit and cabin quickly became saturated with the smell of dirty socks. It was very strong and overpowering for several minutes. The smell diminished somewhat at the lower altitudes but continued to be present at a lower concentration all the way to the gate. This problem had been written up the previous day. It had an oily smell to it and burned eyes and throat. It felt like it was more difficult to concentrate during this fume event. After arriving home I experienced headache. All 3 pilots and purser felt the smell was abnormally strong. I did not have the opportunity to question the rest of the flight attendant crew. It was written up for further inspection by maintenance.
