Prevalence of Inclusion Body Myositis: how many people are affected worldwide, differences by sex and region, with sources.
Inclusion Body Myositis (IBM) is a rare and progressive muscle disorder that primarily affects older adults. It is characterized by muscle weakness and wasting, particularly in the arms and legs. IBM is considered one of the most common acquired muscle diseases in individuals over the age of 50.
While the exact prevalence of IBM is uncertain, it is estimated to affect approximately 1 to 9 individuals per million worldwide. However, due to underdiagnosis and misdiagnosis, the true prevalence may be higher. IBM is more prevalent in men than women, and its incidence increases with age.
IBM is a chronic condition with no known cure. The disease progresses slowly over time, leading to significant disability and reduced quality of life. The exact cause of IBM is still unknown, but it is believed to involve a combination of genetic and environmental factors.
Early diagnosis and management of IBM are crucial to help alleviate symptoms and slow disease progression. Treatment typically involves a multidisciplinary approach, including physical therapy, medication, and assistive devices to improve mobility and maintain independence.
