REM Rapid Eye Movement - What Is REM Disorder?

REM rapid eye movement is when we are dreaming our brain is actually sending signals to our muscles, depending on what we're dreaming about. But REM disorder is when that paralysis doesn't happen at all. And so, the person is dreaming, and they are acting out everything in their dreams. In people that have REM disorder, that's quite associated with early onset Alzheimer's and neurodegenerative diseases.
