My husband is undiagnosed but am sure he is suffering from dementia. GP will not do anything as he is having issues with his liver and they want to investigate urgently before referring for memory tests. Today I had the scare of my life, he drove in the roundabout the wrong way. Loads of traffic, the sheer terror in my face must have been seen by the other drivers. The traffic was in slow motion and I did gesture for other drivers to let him go by. He is usually ok with short distance and familiar places but we went to Tesco to get petrol as we rarely go there he got disorientated. He does seem to realise the mistake he made and how dangerous it was. I need some advice how do I stop him from driving, do I tell DVLA or the police? He does not think there is a problem as he cannot remember what he did. I am not going in the car with him, he can drive on his own . Should I tell the police I do not think he is safe.? Currently we only use the car once a week or less shopping only 15 mins drive. We can do without a car. I was also thinking to let the car mot runs out in June and get the car scrapped. Can anybody relates pl? Thanks
