Are there symptoms to predict the sudden loss of coordination?

Loss of coordination. The loss of coordination is itself a symptom, and sometimes a sign. There are many ways coordination can be impaired, from inner ear problems to brain stem strokes, to acute drug toxicity (including alcohol). More information is needed. I suggest you discuss the problem with your doctor or a neurologist. If you are abruptly, severely impaired, i suggest going to to an emergency department.
