Frequent falls could be a symptom of what diseases? I know that vertigo and ear?

problems could be to blame. But, what else could it be? At age 75 I just started suddenly heading for the floor- even when holding on to something sturdy like a refrigerator. Any Ideas? I do have a doctor appointment next week.

Parkinsons disease
Parkinsonian diseases (Progressive supranuclear palsy, Multiple system atrophy, etc.)
It could also be neuropathic
I would look down before you take steps and move deliberately and carefully
If you need to a supportive device may be helpful
Seek further medical attention
Your physician may recommend that you see a neurologist.
