MS PowerPoint is bad for the brain
Researchers at the Australian University of New South Wales found that PowerPoint presentations could be hazardous to health.
The combination of sound and visual information is a typical example of a PowerPoint presentation. Such slide shows make it difficult to capture information, as people cannot perceive a large amount of sound and visual material - of course, a person understands both that and the other, but only separately.
Professor John Sweller (John Sweller) said that the human brain is not able to perceive such information for more than a few seconds ("theory of cognitive load"). An oral comment explaining diagrams is perceived normally, but if the words are accompanied by printed text, then the person cannot adequately perceive the presentation material.

PS: Sweller is not the first to oppose PowerPoint. In 2003, Edward Tufte, a professor at Yale University, also wrote about the dangers of PP in his book Cognitive Style of Powerpoint: Pitching Out Corrupts Within.
