Welcome in H.C.M.
I have gone through your query regarding unsteadyness, loss of memory and loss of orientation.
As per your symptoms it appears as you are having some central lesion for vertigo
, beause loss of memory and loss of orientation are the characterstic of central vertigo. You please consult neurologist
for detailed neurological examination, investigations and treatment.
Till you are waiting for neurologist you may take stemetil
for getting temporary relief.
