There was a trend for hallucinations, ICD, and psychiatric disturbances to occur more frequently in GBA1-PD compared to the mutation-negative control group and idiopathic late-onset PD, but this was not statistically significant; advanced therapeutic interventions, including deep brain stimulation (DBS) and levodopa–carbidopa intestinal gel (LCIG) therapy, were more frequently required by this group [45]. This evidence concerns the gene GBA1 and Atypical behavior.
