The field of neuroethics examines the unique ethical questions that arise in working with patients with brain disorders and how the study of neuroscience informs ethics research. The goal of the Pragmatic Clinical Neuroethics research group is to study, empirically, patients’ and their family members’ goals and values in the context of Parkinson’s disease (PD) and applicable treatments, such as deep brain stimulation (DBS).
Results of our studies have identified the reasons PD patients seek DBS treatment and the extent to which DBS addresses their goals. These data demonstrate that patient goals are not measured sufficiently using existing standard clinical measures to determine treatment efficacy and that patient goals change over the course of DBS. These results have very clear and pragmatic implications for the development of outcome measures that reflect patient goals and highlight the importance of an informed consent process that includes a systematic, clear assessment of patient goals with a discussion regarding the possibility that some goals may change over the course of DBS.
Our most recent work assesses, systematically, patient and family member's most valued personality characteristics and the extent to which PD and DBS impact those important personality characteristics. Our goals are to identify whether PD and/or DBS treatment results in changes to an individual's personality, to determine if commonly used personality measures can capture patient values fully, and to examine the consistency between patient and family member ratings. Our preliminary data suggest that existing personality measures may not identify fully the characteristics that are most important to patients and their families. In addition, these data highlight the importance of pro-social behaviors, such as kindness, love, and compassion. We have begun to extend the breadth of this study to include patients with other neurodegenerative disorders. This effort seeks to examine the relationship between the underlying neurobiological mechanisms and the individually identified important personality characteristics. These data have implications in the delivery of healthcare, the informed consent process, and philosophical and public discussions surrounding personality and identity by systematically incorporating the perspectives of patients and their family members.
Finally, our team recently secured funding from the Ohio Humanities to support public discussions examining various representations of personhood and personality in the context of a diagnosis of dementia. Our goal is that the data that emerge from our work will help reduce the stigma associated with a diagnosis of dementia.
Dr. Kubu and her team have secured a recent grant that studies Essential Tremor patients. These patients will share their perceptions of treatment options, behavioral and functional goals and changes in personality characteristics. Their tremors will be assessed using a new I phone app and also an accelerometer device. The information gathered will give doctors a better understanding of expectations, experiences surrounding treatment decisions, control, personality changes and the severity of the patients tremor before and after their chosen treatment method.
