63 Hz of an attention-deficit disorder (ADD) dextroamphetamine responder before and after medication. Figure 8 shows VARRTA images at 5.85 Hz of dextroamphetamine nonresponders before and after medication. An examination of this figure shows worsening with medication.

It should also be noted that the responders and nonresponders differed according to the VARETA frequency. Figure 8. Quantitative electroencephalography (qEEG) VARETA Inhibitors,research,lifescience,medical images at 5.85 Hz of an attention-deficit disorder (ADD) dextroamphetamine nonresponder before and after medication. The final grouping that will be reported in this paper consists of a group of patients with schizophrenia, which were subtyped into five clusters (Figure 9). Only members of cluster 1 showed a greater than 25% reduction in Inhibitors,research,lifescience,medical Brief Psychiatric Rating Scale (BPRS) with the use of haloperidol. Members of cluster 3 responded best to risperidone. What is apparent is that there were differential responses to medication as a function of cluster membership. Figure 9. Schizophrenia clusters (power). These three clinical examples demonstrate the variability in the pathophysiology within a so-called

diagnostic category. Conclusion Figure 10 represents an uninformed cluster analysis of a mixed population containing both selleck products normal and abnormal individuals. They were clustered without diagnosis and then later grouped by categories ranging from normal through the various diagnostic labels. As is obvious, whether Inhibitors,research,lifescience,medical normal or any other clinical

category, there was variability of cluster membership. Some members of a particular diagnostic category were in a particular cluster, while others of the same diagnostic category were in other clusters. What, is particularly striking is Inhibitors,research,lifescience,medical that while many normals are in cluster 10, patients with a variety of psychiatric disorders can also be found in cluster 10. This raises the question as to whether these are normal Inhibitors,research,lifescience,medical people only in the sense that they have not yet, become ill, but in fact have the trait variables that might be manifested in a variety of different diagnostic categories. Belonging to a particular cluster docs not identify whether or not an individual will manifest clinical illness. Ultimately, the task the is to use three-dimensional source localization and more refined analysis of the pathophysiology to separate trait from state and thereby identify individuals who are at future risk from those who are not. Finally, developing a better understanding of pathophysiology will lead to more specific and more effective treatment of the subtypes of various psychiatric syndromes. Figure 10.
