My husband's memory has been declining over the last 2 years but he consistently refused to go to the GP, anyway i persuaded him by saying he needed to rule out other causes for the memory loss e.g. anaemia, vitamin deficiencies, depression etc, and then he agreed. He passed the memory test, had blood tests which showed a folate deficiency and he was put on folic acid for 4 months. However, there hasn't really been much improvement memory wise and the GP is going to repeat the memory test in 6 months.
