Depression and Apathy across Different Variants of Progressive Supranuclear Palsy

Research output: Contribution to journalArticlepeer-review


Background: Apathy and depression commonly occur in patients with progressive supranuclear palsy (PSP)-Richardson's syndrome variant; depression often requiring treatment. Little is known, however, about apathy and depression among other PSP variants. Methods: We prospectively studied 97 newly diagnosed PSP patients. All were classified into a PSP variant using the 2017 Movement Disorder Society-PSP criteria and administered the Geriatric Depression and Apathy Evaluation Scales. Differences in apathy and depression frequency and severity across six variants, and secondarily across PSP-Richardson's syndrome, PSP-Cortical and PSP-Subcortical, were analyzed using ANCOVA and linear regression adjusting for disease severity. Results: Depression (55%) was more common than apathy (12%). PSP-Speech/Language (PSP-SL) variant had the lowest depression frequency (13%) and lower depression scores than the other variants. No differences in apathy frequency/severity were identified. Conclusion: PSP-SL patients may have less depression compared to PSP-Richardson's syndrome and other PSP variants.
