Abstract
In this report we describe a patient with a clinical diagnosis of dementia with Lewy bodies, who had hallucinations of reading her thoughts in the air although she was alexic and unable to read. She also had severe visuoperceptual deficits and closing-in phenomenon. SPECT imaging demonstrated hypoperfusion of the left parieto-occipital cortices together with hyperperfusion of the left orbitofronto-temporal areas. Her visual text hallucinations may represent another type of textual hallucinations related to syntacto-semantic network hyperactivation, which is implicated in auditory hallucinations in schizophrenia.
