Visual hallucinations in posterior cortical atrophy.
BACKGROUND Visual hallucinations have been reported to occur in up to 25% of patients who meet the criteria for posterior cortical atrophy (PCA). It is not known, however, whether patients who meet the criteria for PCA and have hallucinations are different from those who meet the criteria and do not have hallucinations.

15 صفحه اولSeeing faces :
The neural mechanisms responsible for triggering visual hallucinations are poorly understood. Here, we report a unique patient whose hallucinations consist exclusively of faces, and which could be reliably precipitated by looking at trees. Using functional Magnetic Resonance Imaging (fMRI), we found that, while face hallucinations was associated with increased neural activity in a number of cor...
متن کاملNeural Mechanisms of Short-term Visual Plasticity and Cortical Disinhibition
iii ACKNOWLEDGEMENTS I wish to thank my advisor, Paul Corballis, for his guidance, patience, and friendship all these years. Without his mentorship I could never have made it this far. I would also like to thank my dissertation committee members Parks have always been a major source of inspiration and support. I cannot thank them enough. Most of all, I must express an incredible degree gratitud...
متن کاملChanges of Retina Are Not Involved in the Genesis of Visual Hallucinations in Parkinson's Disease
Parkinson's disease (PD) is characterized by motor and nonmotor symptoms. Nonmotor symptoms include primarily visual hallucinations (VH). The aim of our study was to establish whether patients with PD and visual hallucinations (PDH+) have structural changes of retina detected by an optical coherence tomography (OCT) in comparison with PD patients without visual hallucinations (PDH-). We examine...
