My mother-in-law is 80, and has been having these frequent dizzy spells. She feels a tingling in her arms and hands, and hears a ringing which starts at the back of her neck and moves up into her head when it happens. She also loses her balance (has fallen twice), and has had a few uncontrollable jerky movement of the arm, and is aware of slight body movement. She isn't confused at all after the attacks and is awake during most of them. (only the times she's fallen does she not quite know how it happened, but was aware that she was going to fall - managed to catch herself and stop herself once) She has been for a cat scan, another scan to show blood flow to the brain, and has had quite a few blood tests done as well. Her cholesterol isn't anything to worry about, she doesn't have hight blood pressure, and the scans were all fine. She also had an ECG, which showed some irritation on the left side of the brain. They also ruled out epilepsy. The doctor has said its probably hardening of the arteries in and around the brain which is causing the attacks. could this be? What more can we do? Yesterday we had to be with her all day, and she sat in one spot - its no life for someone as active as she normally is. I'm not happy with what they have concluded, do you have any input or suggestions?
