Is it true that president Reagan had had alzheimer's disease before his second term started?

Meaning during his entire second term was he suffering from alzheimer's disease?

Very interesting to know how he managed got elected while with dimentia. He must have been one hell of an actor to fake metal health.

His handlers did a good job of keeping him away from the press.
There is one clip later in his 2nd term where he's being interviewed, and Nancy is whispering the answers to him the entire time.
When he said "Oh, I don't recall that" about a thousand times during the Iran-Contra hearings, he really meant it. His brain had been wiped clean by that time.

false. Ronald Reagan was diagnosed with Alzheimer's disease in August 1994 at the age of 83, well after the end of his second term as the U.S. president.

Ronald Reagan won the U.S. presidency in 1980, at the end of a decade of humiliation and frustration for the American people. using his affable personality as a potent political weapon, Reagan helped to restore confidence in the country's future and went on to convert millions of Americans to his conservative political ideology. during the 1980s, Reagan oversaw a sustained economic recovery, driven primarily by one of the great bull markets of all time on Wall Street. soaring profits in the stock market minted millionaires by the thousands, lending the Reagan Era a certain gold-rush aura as more people attained spectacular wealth than ever before in American history. looking beyond America's borders, the 1980s brought first heightened tension and then unexpected victory in the decades-old Cold War with the Soviet Union; the peaceful collapse of the global Communist bloc Reagan once denounced as an "Evil Empire" stood as a monumental triumph in American foreign policy.

not sure about the entire term. but if you watch him towards the end of his 2nd term you can see where he looks incoherent at times
