Research over the years has identified many underlying biological abnormalities, mitochondrial dysfunction among them, but the etiology remains uncertain. 2 No intervention has been proven effective in restoring the ability to work. 3 Primary mitochondrial [journals.sagepub.com]

Other etiologies such as deconditioning, obesity, malignancy, anemia, and sleep apnea are described less frequently ( 1-4 ), and often the cause remains elusive after an aggressive evaluation ( 3 ). [atsjournals.org]

Within the mitochondrial diseases, PMM are very common but real epidemiological studies are not available yet. This is also because PMM often go misdiagnosed or undiagnosed so determining their true frequency in the general population is difficult. [rarediseases.org]
