Long COVID-19 outcomes of patients with pre-existing dementia.

Background: Although COVID-19 has been linked to worse acute outcomes in patients with some neurodegenerative disorders, its long-term impact on dementia remains unclear.

Objective: To investigate the outcomes of COVID-19 survivors with dementia.

Methods: This retrospective study evaluated 9806 patients with dementia in the Montefiore Health System (January 2016 to July 2023).

SARS-CoV-2 infection increases long-term multiple sclerosis disease activity and all-cause mortality in an underserved inner-city population.

Background: Although certain subsets patients with multiple sclerosis (MS), an immune-mediated disorder, are at higher risk of worse acute COVID-19 outcomes compared to the general population, it is not clear whether SARS-CoV-2 infection impacts long-term outcomes compared with MS patients without COVID-19 infection.

Objectives: This study investigated MS disease activity and mortality 3.5 years post SARS-CoV-2 infection and compared with MS patients without COVID-19.
