'Top Gear' star Richard Hammond has revealed that he has suffered from depression since being involved in a high-speed car smash in 2006.
Speaking to The Sunday Times, the television presenter said: "I damaged all the complicated bits of the brain to do with processing and emotional control."
"[I was] prey to every single emotion that swept over me and I couldn't deal with it. I had to relearn things from scratch."
Hammond also said: "I'll still have a week when I'm freaking out about something and I'll realise it's because I'm encountering a new emotional state and I have to evolve a new strategy to cope with it."
"My memory is a lot better but the other day I forgot the PIN numbers to all my cards. All of them. Completely gone."
The star suffered a "significant" brain injury in September 2006 when the jet-powered dragster he was driving went off a track and crashed at a speed of 288mph.
