A differential diagnosis is important to distinguish sensory neuronopathy from other related conditions, such as sensory and ataxic neuropathy. You may find that you have more limitations than before your diagnosis. SG was confirmed electrophysiologically with complete absence of sensory nerve action potentials (SNAPs) or asymmetrical sensory fiber involvement (asymmetrical SNAPs) with no motor involvement. The heart rate increase was noteworthy during hypotension in patients 1 and 3 (but not in patient 2, who had a pacemaker), suggesting that compensatory tachycardia during hypotension might be a marker of ASANN, in contrast to other causes of neurogenic orthostatic hypotension (e.g., synucleinopathies, diabetes or amyloid) in which the heart rate response it typically blunted.
