Trump took the test during the annual physical that is customary for presidents at the Walter Reed National Military Medical Center in Maryland on Friday.
"The president is mentally very sharp, very intact", Jackson said.
Jackson came under fire for saying that Trump is in "excellent" health while some of the numbers provided by the White House in the summary of Trump's physical told a different story.
One example was Los Angeles-based baseball player Albert Pujol, who Gunn said was also 190cm and 108kg.
"I can promise you there is absolutely nothing that I'm withholding from this", Jackson said.
The screening was carried out using a test called the Montreal Cognitive Assessment, on which Mr Trump scored 30/30, Dr Jackson said. The President said he would like to lose some, according to the doctor.
Initially, the White House had suggested that tests of mental function would not be a part of the physical, which was conducted on January 12 by Dr. Ronny Jackson, however it was eventually included in the exam at the request of the president.
The test looks for signs of dementia or Alzheimer's, an incurable, degenerative brain disease, but doesn't assess psychiatric fitness.
Candidates first have to copy a cube, link up numbers to the appropriate letter in the alphabet (A=1, B=2, etc) and draw a clock showing the time 11:10.
Specifically, skeptics don't believe the president actually stands at 6-foot, 3-inches and weighs just 239 pounds. Dr Jackson said he could make no clinical findings in this area and perhaps it was due to a dry mouth brought on by medication the president had taken. His blood pressure was 122/74, within normal bounds, and his cholesterol was on the high side, Jackson said.
Jackson credited the results to genetics.
Jackson said he would increase Trump's daily dose of Crestor, a cholesterol-lowering drug, and bring in a nutritionist to work with White House chefs. Jackson said he would increase that dose in an effort to get Trump's so-called "bad" cholesterol, or LDL level, below 120; it now is 143.
With his reported eating habits and lack of exercise, it made sense for the White House to "release all of this data to show that ... he is in good health", Mishori said.
"We discussed diet, exercise, and weight loss", the doctor said in his report summary. "Those four factors alone put him at a higher risk for cardiovascular disease", she said.
Presenting the outcome of Trump's medical fitness that the President could eat KFC and McDonald's and still be in great shape because God gave him "incredible genes", the doctor declared the president as "very healthy" and his overall health "excellent" in spite of his unhealthy habits.
In her statement Wednesday, Nielsen said she is "thoroughly disappointed" that attention keeps being given to the meeting, when "we have serious and urgent border and immigration issues to address". "I get more exercise than people think".
