I go to all of my husband's doctor's appointments. I keep a diary of his behaviour - I phoned his doctor and explained what was happening and made an appointment for stomach issues. (could be any issue that he is experiencing) while there, the doctor asked a few questions and did a questionnaire test. My husband did well; he has a university degree and keeps up with world affairs. After the testing, I gave my diary to the doctor, and he gave the diagnosis of Vascular Dementia and was referred to the local dementia team. The doctor informed me that the diagnosis would not have been so early without the diary. Over time, his dementia has worsened, and I still keep a diary of his behaviours, and it will probably be useful when he has to be in care.
