[Myalgic encephalomyelitis : etiopathogenesis, diagnosis and treatment].

Myalgic encephalomyelitis (ME), also known as chronic fatigue syndrome (CFS), is a neurological disorder involving multiple pathophysiological mechanisms and etiologies. Symptoms include asthenia, myalgia, post-exertional malaise and neurocognitive disorders. While the numerous patient complaints pose a diagnostic challenge, the advent of new technologies paves the way for innovative methods to reveal ME. The heterogeneity of the disease's mechanisms complicates the search for effective treatments but also offers the prospect of numerous beneficial molecules. Combining treatments targeting mitochondrial dysfunction, oxidative stress, inflammation and immunological disorders appears to be the current optimal therapeutic approach.
