Put down as much detail as possible - especially if the form doesn't seem to cover your condition. It is your overall pattern of needs or problems that will be looked at. Don't delay returning the form, you could lose money. A lot of people get these allowances when they claim but some people are turned down. If you are turned down or you think you should have got a higher rate, you can ask the Benefits Agency to revise your case.
Most revisions are successful.
You then have the right to appeal to an independent tribunal. Get advice if you want to have a revision or an appeal. It is important to seek advice as soon as possible as a revision must be requested within 1 month of the date of the decision or 1 month and 14 days if you make a request for a written statement of reasons. If you are still unhappy with your benefit, you have a right of appeal. This should normally be done within a month of you being sent a decision by the Benefits Agency.
