Distal acquired demyelinating symmetric (DADS) neuropathy is a variant form of chronic inflammatory demyelinating polyradiculoneuropathy. A 54-year-old man presented with gait disturbance owing to weakness in both legs. Nerve conduction studies showed demyelinating sensorimotor polyneuropathy, and laboratory studies demonstrated anti-GM1 and anti-GD1b IgG antibodies, but no anti-myelin associated glycoprotein activity. We suggest that an antiganglioside antibodies assay needs to be applied when DADS neuropathy is suspected in order to improve the classification of dysimmune neuropathies.
