Parkinson's disease (PD) patients who are carriers of glucosylceramidase β1 (GBA1) gene mutations typically have an earlier age at onset and a more aggressive disease course, with a higher burden of neuropsychological issues. The use of deep brain stimulation (DBS) in PD patients with disabling motor fluctuations and absence of dementia is a widespread therapeutic option, often with good results in terms of improvement in activities of daily living and quality of life. Although all PD patients, when fulfilling the common selection criteria for DBS, can benefit from this intervention, some studies have raised attention toward the fact that PD patients who are carriers of GBA1 variants may have a worse DBS outcome possibly due to an accelerated progression of cognitive decline. From this viewpoint, we summarize the current literature, highlighting the knowledge gaps and proposing suggestions for further research as well as for clinical practice in this timeframe of uncertainty related to using DBS in PD patients who are carriers of GBA1 variants.
