Incorporating Genetics and Genetic Counseling in Neurology Clinics: A Survey of Neurologists’ Perceptions and Current Practices

Abstract

Neurogenetics has grown significantly in recent years, yet these advances have not always been fully incorporated into clinical practice. In previous studies, neurologists reported limited confidence in ordering and interpreting genetic tests, highlighting a gap between genetic advances and their application in neurology. Genetic counselors are uniquely trained to facilitate genetic testing, interpret results, and provide psychosocial support, ultimately improving patient care. This study aims to assess the current utilization of genetic testing and genetic counseling within neurology settings. Our study also looks at the association between genetic knowledge and neurologists' perception of value in access to genetic counseling. Through evaluating neurologists’ perspectives on genetic testing and counseling, we aim to demonstrate the importance of integrating genetic counselors into neurology settings to improve patient outcomes. A cross-sectional survey was used to assess the utilization of genetic testing and genetic counseling in neurology clinics. Surveys were distributed to board-certified neurologists through email. Quantitative data was analyzed to identify associations between neurologists' experience and their use of genetic services. Out of the 28 completed responses, most respondents have been practicing neurology for more than 15 years and work in urban settings, yet 68% do not have a genetic counselor embedded into their clinics. Overall, neurologists with more genetics training are more likely to order genetic testing and also feel more comfortable performing genetic counseling roles (? = 0.739, p = 3.66 x 10⁻⁵). Additionally, greater years of experience in practice correlated with increased comfort performing genetic counseling roles (? = 0.519, p = 0.005). However, we found no significant relationship between physicians’ level of genetics training or comfort level performing genetic counseling roles and their perceived value of having a genetic counselor in neurology settings, suggesting that the majority of neurologists value genetic counselors. These results highlight the need for increased integration of genetic counselors in neurology settings to enhance patient care for genetic services.
