Science Correlation between less frequent bowel movements and dementia

A study of over 40,000 people concluded that patients with dementia often have cases of constipation. The study involved about 19,000 men and 23,000 women between the ages of 50 and 79 living in Akita, Nagano, Ibaraki, Kochi and Okinawa prefectures in 2000 and 2003. [...] Researchers followed up with the group until 2016, comparing the rates of those who were assessed as requiring care due to dementia. According to this data, 9.7% of men and 11.7% of women had been diagnosed with dementia. Analyzing the relationship between the frequency of bowel movements and dementia, the risk of dementia was about 1.8 times higher in men and 1.3 times higher in women who had fewer than three bowel movements a week compared to those who had a bowel movement every day. The less frequent the bowel movements, the greater the risk of dementia, trends in the data showed.
