Try these tips to have productive discussions about giving up driving:  
     - Include others on an ongoing basis: The person with
     dementia’s family members and friends, as well as professionals like
     their doctor, lawyer, financial planner, and care manager can all
     provide support for both you and the person with dementia on an ongoing
     basis. 
     - Gauge the best times to talk: Pick times that
     work well for the person with dementia’s attention span and energy
     level. If the person with dementia becomes angry or agitated, gently end
     the conversation and start it up again later. 
     - Be open: Make sure the person with dementia
     feels comfortable sharing their thoughts and feelings. Listen and
     appreciate what the person with dementia thinks, as well as what others
     involved in the discussion have to say. 
     - Be prepared for emotional reactions: Be ready
     for reactions like anger and/or sadness, which may seem especially
     extreme. Keep in mind that this may in part be due to the memory and
     insight issues that are often associated with dementia.
 
 
     - Talking about it is good to dispel feelings of frustration and loss.
     It's a big thing, to give up driving after a long time. It signifies a
     big change and can be very difficult.
