Some may only have a slight vertigo or temporarily loss of balance a few times a year. Still others feel unsteady all day long for long periods. The immediate outcome of one of these episodes is total exhaustion and the need to sleep for hours. This causes the loss of balance. It is this sudden loss of balance, which often forces the person to fall to the ground.
Many injuries occur because the people have no warning to protect themselves or break their fall.
They are often seen as staggering. If someone is driving, their head might be suddenly flung to the side or shaken, ending up with the person being completely disorientated. To the sufferer this is a very difficult condition to deal with. They can be totally debilitated for varying lengths of time. But what is even worse is they can't plan ahead.
