Also sometime known as myalgic encephalomyelitis (ME), chronic fatigue syndrome is a condition that causes extreme fatigue over a prolonged period. The cause is unknown, although it sometimes develops after an infection or psychological trauma.
The main symptom is persistent, overwhelming tiredness. Other symptoms may include difficulty concentrating, poor short-term memory, muscle or joint pain, headaches, and sleeping problems.
The syndrome is also often associated with anxiety or depression. The severity of symptoms can vary from day to day, or even during the same day. There is no specific treatment for this condition, but options that may be offered include cognitive behavioral therapy (CBT), graded exercise therapy, or medication to relieve symptoms. Chronic fatigue syndrome is a long-term condition, but it may clear up after several years
