Olfactory hallucinations in schizophrenia: A neuropsychological investigation

Olfactory hallucinations have been found to be indicative of serious psychopathology and poorer prognosis in schizophrenia. Using a neuropsychological approach, my research primarily aims to identify the neuroanatomical structures and neural circuits implicated in olfactory hallucinations in schizophrenia, and to further identify distinct neuropsychological factors which discriminate between patients who experience olfactory hallucinations and patients who experience hallucinations in other modalities (in particular, auditory verbal hallucinations), as well as healthy controls. An additional aim of the project is to attempt to identify the disrupted cognitive processes that may underlie the generation of olfactory hallucinations in schizophrenia, through incorporation of a cognitive neuropsychological perspective into the study. By focussing on less frequent but characteristic symptoms of schizophrenia, such as olfactory hallucucinations, insight may be gained not only into the processes underlying the generation of olfactory hallucinations, but also into those underlying hallucinations generally, and may therefore provide knowledge about the heterogeneity of symptoms within the broader clinical group.
