Indicative biomarkers of Lewy body disease with oral sensory hallucinations in the older people

Nonvisual hallucinations, including OSHs, have been identified as clinical features that have potential to support the diagnosis of Parkinson's disease (PD) and dementia with Lewy bodies (DLB). Since individuals with PD/DLB have alterations in the dopaminergic system due to alpha-synucleinopathy, research suggests that OSHs may also be linked to these alterations. [...]this retrospective case series suggests that OSHs in older individuals, even in the absence of primary PD/DLB symptoms, may be associated with dopamine dysfunction.
