Possible effectiveness of low-dose pregabalin in a patient suffering from Lewy body disease and chronic pruritus.

Many patients with Lewy body disease (LBD) complain of pain, although the detailed mechanism responsible for LBD-related pain remains to be clarified. Moreover, there does not appear to be any reports about LBD patients suffering from an itching sensation. In this report, the case of an LBD patient who experienced severe itching that persisted for over 6 months, which was treated successfully with low-dose pregabalin therapy, is described. This is the first study to report the effects of low-dose pregabalin, which has been used to treat LBD-related pain, to treat itching in a patient with LBD.
