Visual hallucinations: an EEG and non-invasive Stimulation study (VEEG-Stim)

Collaborators: Nicholas Murphy, Sara Graziadio, Alison Killen John-Paul Taylor

Disturbances to visual perception are a common in Lewy body dementias (LBDs) and may contribute to the development of visual hallucinations. However the causes of visual perception problems and visual hallucinations is still poorly understood which makes treating this symptom difficult.

Lewy body visual hallucinations EEG

In this study our aim is to understand how visual perception is affected in LBD. We use combined transcranial magnetic stimulation (TMS) and electroencephalography (EEG) to assess the visual system and compare our findings between people with LBD who hallucinate vs those that don’t and healthy control groups to better understand the processes that occur in the brain that may lead to occurrence of visual hallucinations.
