Menière's disease. II. A neuropsychological study.

23 Menière patients were examined with a extensive battery of neuro-psychological tests. In a previous investigation, the authors had demonstrated that patients with long-duration Menière's disease had psychological disturbances, presumably localized in the nondominant hemisphere. In the present investigation, the patients had short-duration Menière's disease, and we were unable to replicate the results of the former investigation. It is concluded that the central changes in nondominant hemisphere function develop over a long period of time. It is hoped for that further neuropsychological investigations of Menière patients will give more information on what is primary in Menière's disease: peripheral, sensory or central neurological changes.
