Introduction: Multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) are two relatively common forms of atypical parkinsonism seen in movement disorder clinics. This study provides an insight into the cognitive dysfunction in these two diseases. Aims: This study aims at assessing the cognitive and executive dysfunction and investigating the relationship between age, education, Montreal cognitive assessment (MOCA), and frontal assessment battery (FAB) score in a group of Indian patients with MSA and PSP. Materials and Methods: This is a hospital-based observational study with the recruitment of patients of MSA and PSP based on consensus criteria and The National Institute of Neurological Disorders and Stroke and Society for Progressive Supranuclear Palsy criteria, respectively. A total of 50 patients of MSA and PSP admitted or attending outpatient department in the Department of Neurology, SMS hospital, Jaipur, were analyzed for cognitive and executive functions between December 2016 and December 2018 using MOCA and FAB. The Student's t-test was used. The level of significance was determined as itsP value withP < 0.05 taken as statistically significant. Results: On MOCA, impairment was observed in 24% of cases of MSA and 92% of cases of PSP. On FAB, impairment was observed in 20% of cases of MSA and 72% of cases of PSP. Conclusions: Cognitive dysfunction is a major finding in PSP and MSA patients. Thus, cognitive dysfunction in a patient does not rule out MSA as considered in the previous literature and is an important diagnostic finding in PSP; yet requires future research on a larger scale.
