People who have attacks, whatever the cause, may be able to claim benefits depending upon the effect the attacks have on their life.
If you have received benefits or been unable to work because you thought you had epilepsy, this should not change simply because your seizures have a different cause. NEAs are real attacks which can be disabling.
There is a good chance that with the right treatment your attacks will improve and you may be able to work again in the future. Sometimes returning to work helps people get better.
If you have not worked for a while it may be difficult suddenly to return to work. Increasing your hours gradually (perhaps with extra help from work colleagues at first) may help you to build up your confidence.
The Jobcentre Plus can give you advice about returning to work after claiming benefits. You can also talk to the Citizen’s Advice Bureau or visit GOV.UK if you have any questions about benefits.
