He cannot put one foot in front of the other without difficulty

Joe Biden barely made it to the top of the steps on Airforce One Wednesday, misplacing his own feet despite a concerted effort on his part not to fall over again.

Holding a bag and an umbrella, Biden slowly eased his way up the steps in the rain, but still managed to lose his coordination half way up.

It clearly wasn’t a slip, Biden has trouble putting one foot in front of the other. He loses his train of thought and makes phantom steps.

This is a known signifier of dementia.

Sufferers often walk with slow and irregular steps and find it hard to negotiate turns, climb steps, and avoid obstacles.

Having made it to the top, Biden turned around and gave a comical salute that would see even the most lenient drill sergeant yelling their lungs out.
