I doubt it, unless you are being required to prove it.

DVLC ? and you'll need to mention it on any future motor insurance

You don't need to inform any authority, that is the job of your doctor. You
will receive a notice from your DMV office on the fact of your drivers
license revoke.

As you've posted to a uk group, I'm assuming you're in the UK.

You MUST inform the Driver and Vehicle Licencing Agency Medical Branch
- in writing is best.

In my case, the "suspension" of the licence was not immediate, but was
effective more than three months after I informed DVLA.  Seizure date
was 08 August, suspension date was 15 December!  It often takes time
to process the paperwork.

You can shorten the timescales by voluntarily surrendering your
licence - see <URL:http://www.dvla.gov.uk/drivers/dmed1.htm#10>
Suspension will be for one year from the date they give you, or one
year from the date you voluntarily surrendered your licence.

You can apply for re-instatement about one month before the year has
passed, and when you submit the application (DVLA will send you a
reminder form, if you did not voluntarily surrender your licence,
complete with medical report forms for completion) you may put a "date
from which you would like the licence to begin" as being at least one
year from the date when DVLA suspended your licence. Unless you hear
to the contrary, you may legally drive from the date you requested,
even if you don't have a licence in your posession.

I am not a lawyer, opinions are my own (but partially based on
experience), etc. Take proper advice (DVLA and your specialist).

As well as the information posted, this link might be of use:

I thought suffers had to be completely free of seizures for a year but
it seems in your category you may be able to continue to have
nocturnal ones and still regain your licence after three years:

You can apply or reapply for your category A, B or P licence as long
as:

   * You have been free from seizures completely for one year OR
   * You have only experienced sleep seizures for a period of at
least three years AND
   * the DVLA/DVLNI is satisfied that as a driver you are not likely
to be a source of danger to other people on the road.
