My partner had a massive stroke 2 years ago .Mike has 100 percent blockage on 1 side and 2 years ago 50 to 60percent blockage on the other side .He cannot walk or sit up and forgets he has a left side.In the last month he is forgetting things , example he orders supper and then wonders where it came from and in the last 2 weeks he has been skipping meals . What does this mean ?Also when we turn him from left to right he gets dizzy.
