Derangement Syndrome...How Many Versions Exist?

 I started counting:

Lincoln Derangement Syndrome (1861–1865)

Grant Derangement Syndrome (1869–1877)

Hayes Derangement Syndrome (1877–1881)

Garfield Derangement Syndrome (1881)

Arthur Derangement Syndrome (1881–1885)

Harrison Derangement Syndrome (1889–1893)

McKinley Derangement Syndrome (1897–1901)

Roosevelt Derangement Syndrome (1901–1909)

Taft Derangement Syndrome (1909–1913)

Harding Derangement Syndrome (1921–1923)

Coolidge Derangement Syndrome (1923–1929)

Hoover Derangement Syndrome (1929–1933)

Eisenhower Derangement Syndrome (1953–1961), although I should stress...this was awful mild

Nixon Derangement Syndrome (1969–1974)

Ford Derangement Syndrome (1974–1977)

Reagan Derangement Syndrome (1981–1989)

Bush Derangement Syndrome (1989–1993)

Bush II Derangement Syndrome (2001–2009)

Trump Derangement Syndrome (2017–2021, 2025–present)....most severe but second to Lincoln Derangement Syndrome

Yes, 19 DS's.  Note, I didn't count prior to Lincoln, and I marginally consider EDS (Ike DS) to exist.  If I ranked the top three.....LDS, NDS, and TDS.  B2DS would be 4th.  

Why they seem to get more intense?  Mostly because of the news media, and inability to win elections for the Democratic candidate.
