It seems having a bad sex life is much more serious than originally thought: scientists at Penn State University say that it could also leave men at higher risk of suffering from dementia. In a study involving 818 men in their 50s who were tracked for more than a decade, scientists found those who had poor sex lives showed a faster decline on memory tests than those who did not. Scientists suggested this may be because individuals with poor sex lives were more likely to face chronic stress, which could cause atrophy of the areas of the brain linked to memory.
But they also suggested it could be a sign of poor heart health, which is also known to raise the risk of memory problems. Other theories included lower levels of testosterone, which could lead to a smaller hippocampus, involved in memory. They also suggested that chronic stress due to a poor sex life or other factors could be behind the results.
