Top Gear presenter Richard Hammond says he is suffering "mortally with depression" and has trouble parking his car since a high-speed crash nearly killed him.
It is the first time the BBC presenter has spoken of his struggle to recover since a damaged tire caused the jet-powered car he was driving to crash at speeds of 460km/h.
"I damaged all the complicated bits of the brain to do with processing and emotional control," Hammond said to The Sunday Times.
"I had to relearn things from scratch and 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."
Hammond also told The Times he had damaged the parts of his brain that dealt with spatial awareness, which made parking difficult and caused problems with his memory.
"Sometimes I have trouble parking and my memory is a lot better, but the other day I forgot the pin numbers to all my cards. All of them. Completely gone," Mr Hammond said.
Hammond returned to the BBC show after only five weeks in hospital, but said that it was "much too early".
"I spent a year recovering and I'm still on the mend. All the swelling has gone down, it's as mended as it's likely to be, it seems to be more a case of rewiring itself," Mr Hammond said.
"I'm a hell of a lot more fixed than I was, but every time something happens, if I make an odd decision, you realise how broken you were."
Hammond joined the top rating show in 2002 and has been a hit with viewers.
Top Gear is shown in more than 20 countries around the world.
