			===Admission===
			*Patients with acute or subacute cases of ataxia should be admitted if benign etiology cannot be established
			*Admit patient if they cannot ambulate safely on their own

			===Discharge===
			*Discharge patients with mild or reversible symptoms as long as they are AAOX4 and can ambulate safely.
			*Consider follow-up with neurology or primary care
