Fact 3. Notable Prevalence in Older Men: A Demographic Insight into RBD
An intriguing demographic trend associated with REM Sleep Behavior Disorder is its higher prevalence in older men. While RBD can potentially affect individuals of any gender and age group, research consistently shows a more significant incidence among men, especially those above the age of 50. This demographic leaning is a key aspect that can guide healthcare professionals in recognizing and diagnosing the disorder.
The reasons behind this gender and age bias in RBD prevalence are not yet fully understood. Some researchers speculate that it could be linked to differences in how men and women dream or variations in hormonal levels influencing sleep patterns. There might also be a correlation between age-related neurodegenerative diseases and the onset of RBD, given the latter’s potential role as a precursor to conditions like Parkinson’s disease.
However, it’s crucial to note that while older men are more commonly diagnosed with RBD, the disorder is by no means exclusive to this demographic. There are cases of RBD reported in women and younger individuals, though they’re relatively fewer in number. Hence, healthcare professionals must maintain a broad perspective when diagnosing RBD, even as they take into account the more likely demographic. (3)
