SO is a GABAB agonist and, as such, also arrests the high energy requiring calcium pace-making activity of these neurons. In addition, blocking calcium entry impedes the synaptic release and subsequent neurotransmission of aggregated synuclein species. As DA neurons degenerate, a homeostatic failure exposes these neurons to glutamate excitotoxicity, which in turn accelerates the damage. SO inhibits the neuronal release of glutamate and blocks its agonistic actions. Most important, SO generates NADPH, the cell's major antioxidant cofactor. Excessive free radical production within DA neurons and even more so within activated microglia are early and key features of the degenerative process that are present long before the onset of motor symptoms. NADPH maintains cell glutathione levels and alleviates oxidative stress and its toxic consequences. SO, a histone deacetylase inhibitor also suppresses the expression of microglial NADPH oxidase, the major source of free radicals in Parkinson brain. The acute clinical use of SO at night has been shown to reduce daytime sleepiness and fatigue in patients with PD.

The occurrence of DM and its secondary complications is also associated with the severity of COVID-19 and high mortality. People with DM have a weakened immune system owing to innate immunity defects affecting phagocytosis, neutrophil chemotaxis, and cellmediated immunity; however, the high prevalence of diabetes in serious cases of COVID-19 may reflect the higher prevalence of type 2 DM (T2DM) in older people. Moreover, DM is linked to cardiovascular illness in older people, which could underlie the correlation between COVID-19 and fatal outcomes. SARS-CoV-2 infects via the angiotensin-converting enzyme 2 (ACE2), which is found in pancreatic islets, and infection with SARS-CoV-1 has been linked to hyperglycemia in individuals who do not have DM.
