One in 100 secondary school pupils could be missing classes because of chronic fatigue syndrome, also known as Myalgic Encephalomyelitis (ME), say researchers.
A study following 2,855 pupils at three schools, published in the online journal BMJ Open, found 28 missed school with chronic fatigue syndrome.
Mary-Jane Willows, chief executive of the Association of Young People with ME, and Rebecca who was diagnosed with the condition at the age of 11, spoke to BBC Breakfast.
