Etiopathologies of self-integration: Disrupting global constructs in cognitive diseases

34th International conference on Mental Health and Psychiatry

Keynote: Int J Emerg Ment Health

Abstract
Extant studies show that several, widely prevalent, cognitive diseases affect the phenomenal construct of self, diminishing the capacity to unify brain and bodily behavior. Schizophrenia, for example, is marked by disturbances of the self construct, seen in such symptoms as an abnormal sense of the body, loss of ego boundary and a confused sense of agency. Likewise, Alzheimer's Dementia manifests as a progressive loss of control of default mode, self circuitries. Global states like the self construct assist integration through operational features characterized by stability, flexibility, and hierarchy, which are required for performance and that are intrinsic to the construct in various behavioral operations. Among the key operations known to be affected by these diseases involve those of motor planning and goal directed, action execution, which are posited to entail disorders of self agency. Schizophrenia, for example, is regarded as a disease of self agency. Conceptually, the motor plan is understood to be teleologically oriented, linking an agent to an objective terminus. Theories of the motor plan invoke a predictive processing model in which the identification of expected actions are confirmed through their sensory identification, a process that could serve to identify the source of actions. However, current evidence indicates that goal specific information is not constitutive to action identification processes of the motor plan and schizophrenia patients have been shown to be capable of identifying their actions in automatic behaviors, while nonetheless impaired in the intentional performance of motor tasks. These data suggest that goal specific information needs to be linked to a representation of the agent a process that, therefore, appears to be defective in schizophrenia. Moreover, it suggests that identification of the agent as the action source is requisite for the execution of motor plans. This talk will explore likely proxies for agent representation in goal execution and their disruption in cognitive diseases like schizophrenia. Hence, action selection processes appear to involve neural mechanisms other than those of action identification. Among these, representations of body posture are likely to be an important proxy for global self-representation during dynamic actions, one that could be directly modified by goal specific content. Recent studies suggest that several structures may assist in structuring goal directed activity, including the orbitofrontal cortex, hippocampus, and dorsal premotor cortex. This talk will explore the relationship between these findings and how schizophrenia may modify the representation of self agency during goal directed activity.
