Negative Thoughts and Brain Power

When it comes to brain power, your thoughts matter.

Stop those negative thoughts! When it comes to brain power, it appears your thoughts matter. That was the eye-opening conclusion of a provocative study published in the journal Alzheimer’s and Dementia. For this study scientists carefully measured the cognitive function of 292 middle-age to older study subjects over a four-year period. The cognitive assessments included measures of memory, spatial cognition, attention, and language.

The study subjects also had their thinking patterns regularly monitored over two of the four years by responding to a series of questions. The thought pattern questionnaire used was specifically designed to identify repetitive negative thinking, RNT for short. RNT includes ruminating about negative past events as well as future sources of anxiety. About a third of the study subjects also had PET scans of their brains specifically measuring levels of the two abnormal brain proteins, tau and amyloid. Tau and amyloid build up in those affected with Alzheimer’s disease.

The findings? Study subjects with greater RNT – these repetitive negative thought  patterns – exhibited a clear decrease in cognitive function and memory over the four-year period. What’s more, they also had more tau and amyloid build up in their brains. It is well-documented that our thoughts have powerful, direct physiologic effects on our bodies so these results aren’t surprising. Thankfully, studies also show that we can change our thoughts patterns through mental training practices, with meditation documented to be one of the very best. 

As someone who was prone to negative rumination in the remote past, I can speak personally to the remarkable power of meditation to mitigate this destructive thinking pattern, and I encourage everyone to explore this simple, yet radically transformative practice. I strive to meditate every day and gratefully achieve that goal about 90% of the time.

Lastly, feel free to share this post with your friends and loved ones because one of the greatest gifts we can give is the gift of better health. ENJOY!
