What other areas of brain imagining are researchers studying?
There is a lot of interest in better understanding the differences between people who develop early and late-onset of OCD. Researchers have provided evidence of neuropsychological differences between these two groups, and further noticed differences in brain activity related to the age of onset. Both, positron emission tomography (PET) and functional MRI (fMRI) will be helpful in understanding the relationship between cognitive functioning and brain activity in early and late onset of OCD (J Neuropsychiatry Clin Neurosci, 2005) An abstract of an upcoming journal article provides information about Low-resolution electromagnetic tomography (LORETA), which is a 3-dimensional intra-cerebral distribution of neuronal electrical activity. Researchers in Brazil utilized LORETA to predict the response of patients to medication therapy for OCD symptoms. They compared the brain activities of ten patients who responded to therapy and seven who did not. The results demonstrated a significant patter
