A common question asked is whether the DVLA (Driver & Vehicle Licensing Agency) need to be informed of a cavernoma diagnosis, particularly if it is an incidental finding and asymptomatic.
The DVLA do require people to disclose a cavernoma diagnosis and a failure to make this declaration can result in a £1000 fine: https://www.gov.uk/angioma-and-driving.
The DVLA will assess each disclosure on a case by case basis, taking into account any symptoms you present with. Many people with cavernoma who disclose their condition to the DVLA are able to continue driving.
If you have a query the DVLA can be contacted by telephone on 0300 790 6801 from Monday to Friday, 8am to 7pm, and Saturday, 8am to 2pm. More information can also be found at https://www.gov.uk/driving-medical-conditions.
