Alda recalled dreaming that someone was attacking him. In the dream, he defended himself by picking up a sack of potatoes and throwing it toward his attacker. But in reality, he wasn’t holding potatoes at all. He had physically thrown a pillow toward his wife while they were sleeping. This unusual incident became an important clue after he learned about a condition called REM sleep behavior disorder, or RBD.

During normal rapid eye movement sleep, the brain temporarily suppresses most voluntary muscle activity, preventing people from physically acting out their dreams. With RBD, that protective mechanism doesn’t work properly. A person may shout, kick, punch, move suddenly, or even fall out of bed while dreaming. Researchers have found an association between this disorder and certain neurological conditions, including Parkinson’s disease. However, experiencing unusual dreams or movements does not automatically mean someone has Parkinson’s.

After recognizing his own symptoms in a medical article, Alda visited a neurologist and requested further testing. Initially, the doctor saw no obvious movement-related signs of Parkinson’s. Nevertheless, Alda remained concerned and pursued additional evaluation. He was diagnosed in 2015 and publicly disclosed the condition in 2018. Rather than allowing the diagnosis to consume his life, he began focusing on exercise, maintaining his activities, and finding practical ways to manage the challenges.

Alda has continued discussing the unusual sleep behavior that preceded his diagnosis. He emphasizes the importance of accepting his condition while maintaining his sense of humor. Medical experts note that persistent dream-enacting behaviors deserve evaluation, particularly when they involve potentially dangerous movements. A sleep specialist may recommend an overnight sleep study to determine whether RBD or another condition is responsible. Alda’s experience offers an important reminder: neurological symptoms don’t always begin in the ways people expect. Acting out dreams can sometimes be a meaningful medical clue, although it isn’t proof of Parkinson’s disease. Recognizing unusual changes and seeking appropriate medical evaluation can help people better understand their health.
