Overactive bladder syndrome is related to bladder dysfunction and is not only suffered by older people, but also by younger men and women even in their 20s.
However, in general, the prevalence is slightly higher in women than in men at the age of 40-50, but increases in men as they get older. It is believed that this is because older men are prone to benign prostatic hyperplasia, which can occur secondary to “overactive bladder”.
