Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME) or ME/CFS, is a complex, chronic illness that affects many body systems [3]. It is characterized by profound tiredness, regardless of bed rest [5], and extreme fatigue that lasts for at least six months [1]. People with ME/CFS are often not able to do their usual activities and may experience symptoms such as muscle pain, headaches, unrefreshing sleep and cognitive difficulties [2][4][6][7][10]. The cause of CFS is unknown but it has been classified as a neurological disorder [9] and there are treatments available to help manage the symptoms [8].

Chronic fatigue syndrome (CFS) is a disorder characterized by extreme fatigue that cannot be explained by any underlying medical condition. Symptoms of CFS include persistent exhaustion, muscle pain, headaches, difficulty concentrating and sleeping problems. Treatment for CFS typically involves lifestyle changes such as getting enough rest and exercise, managing stress levels and eating a healthy diet. In some cases medications may also be prescribed to help manage symptoms.
