Abstract

Background: Deep brain stimulation (DBS) is a neurosurgical procedure approved for treating psychiatric and movement disorders, including Parkinson's disease (PD), essential tremor, dystonia, and other neurological conditions. The widespread use of DBS may not be reflected in the medical education curricula in Saudi universities, thus jeopardizing future patients' access to it. This study aims to investigate the knowledge and attitudes of medical students toward DBS as a therapeutic option.

Method: A descriptive cross-sectional questionnaire-based study was conducted. The survey was distributed on online platforms to acquire responses from different regions of Saudi Arabia. The target population was medical students in the preclinical and clinical phases of medical education from different regions of Saudi Arabia.

Results: A total of 1075 medical students from various medical schools in Saudi Arabia were included. More than half of the students aged 21 to 23 (50.1%) were females (63.2%). More than half of the students have correctly recognized DBS as a Food and Drug Administration (FDA)-approved treatment (59.7%). Only 20.1% of the students stated that they received adequate education/training about DBS. About 53.8% of the students had self-rated their knowledge as poor, whereas 20.6% had rated their knowledge as good. A negative bias was more observed among the older students and students with a family history of DBS treatment. Half of the participants (54.1%) indicated that DBS is associated with severe adverse effects. A significant association between the level of knowledge about DBS and the academic level was observed.

Conclusion: Almost half of the medical students had poor knowledge and unfavorable attitude toward DBS in Saudi Arabia. The current medical curricula are incommensurable with the clinical implications of DBS, which may deny future patients from such an effective therapeutic option. We recommend incorporating DBS teaching sessions to enhance future physicians' awareness and understanding of the benefits of this intervention.
