I am 59 years old male. Bp normal, no biabetic, wt 54 kg. But since last 01 year we feels that 1. Motion is zig-zag, like a drunker. Straight/linear motion is not possible. 2 body vibration increases in longitudinal direction when speed is even normal or standing with two-wheeler. 3. Tendency to fall. 4. Loss of balence. 5. Capturing/ holding an object, reduces. 6. Dual image formation, although it is somewhat control by wearing prism glasses. Please snuggest disease name, is it curable?
