(CNBC) — Autism has emerged as the most expensive medical condition to treat in the U.K., as researchers call for more medical research into the condition.

The condition costs the country at least £32 billion ($54 billion) per year through treatment, lost earnings, care and support, according to a study by the London School of Economics (LSE), published in the JAMA (Journal of the American Medical Association) Pediatrics and backed by autism research charity Autistica.
