Mental abilities, age, and memory occupied a prominent place in the campaign of presidential candidates in the United States. A report stated that President Joe Biden suffers from memory problems.

Former President Donald Trump accused both Biden and Republican presidential hopeful Nikki Haley of lacking the mental capacity to hold the presidency. Haley will face Trump in the primary elections scheduled in South Carolina on February 24, to obtain the Republican Party nomination to run in the upcoming presidential elections. The issue of mental competency has become a major topic in the presidential campaign this year.
