Démence à corps de Lewy atypique révélée par une glossodynie et des troubles pseudo-psychiatriques

Introduction

Among the degenerative diseases of the nervous system, Lewy body disease has the most psychiatric symptoms especially hallucinations, delusion and identification disorders.

Case report

We report a case of Lewy body disease that started with a burning mouth syndrome for three year as the only symptom before the development of a pseudo-psychiatric syndrome (melancholy and Capgras). None of the usual cardinal criteria were present. MRI, cerebrospinal fluid, and DAT scan^® findings enabled the diagnosis.

Conclusion

The dopaminergic hypothesis put forward in some cases of burning mouth syndrome might explain this symptom in Lewy body disease.
