COVID-19 and Brain Injury. COVID-19 may lead to changes in personality and behavior, which require treatment across the continuum of care. Traumatic brain injury, stroke, anoxic brain injury, encephalitis, and other neurological conditions leading to brain insult can be devastating to individuals and those close to them ( Table 1 ).

Let’s do this...

An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor). In other words, an oxidizer is any substance that oxidizes another substance. The oxidation state, which describes the degree of loss of electrons, of the oxidizer decreases while that of the reductant increases; this is expressed by saying that oxidizers "undergo reduction" and "are reduced" while reducers "undergo oxidation" and "are oxidized". Common oxidizing agents are oxygen, hydrogen peroxide and the halogens.
