The increased risk of primary parkinsonism symptoms among individuals affected with GD and carriers for the disorder is well-documented in the literature. However, these risks and case reports often reflect patients with classical Parkinson's disease (PD) symptoms. We report a patient with GD type 1 who was diagnosed with corticobasal syndrome (CBS), a clinical atypical parkinsonism diagnosis, in his sixth decade of life. Our case highlights the need to consider forms of atypical parkinsonism such as CBS in addition to PD in the differential diagnosis of cognitive and motor changes in patients with GD type 1. We also recommend careful assessment and routine monitoring of cognition, mood, behavior, sleep patterns, olfaction, and memory in patients with GD type 1 to identify early symptoms indicative of neurological involvement.ACE, angiotensin-converting enzymeApraxiaAstereognosisAtypical parkinsonismCBS, corticobasal syndromeCHITO, chitotriosidaseCorticobasal syndromeDLB, dementia with Lewy bodiesERT, enzyme replacement therapyGD, Gaucher diseaseGaucher diseasePD, Parkinson's diseaseRBD, rapid eye movement (REM) sleep behavior disorderStereoagnosiaTRAP, tartrate-resistant acid phosphataseJournal article2020-08-01
