Chronic diseases are defined as irreversible conditions without complete recovery or relatively long-lasting conditions.
Health conditions and interventions that we excluded were acute conditions requiring treatment or further diagnostic procedures, e.g. infections such as pneumonia or upper urinary tract infection, exacerbation of chronic conditions, and long-lasting conditions with no or little risk for future complications (Table 3).
Within this proposed concept, we hypothesize that all ASDs, as well as some other social disorders, could generally be viewed as the brain functioning in a "socially reduced mode" or "socially safe mode" (if we may express it symbolically using Microsoft Windows terminology) in response to a variety of more or less specific damaging, overloading and long-lasting conditions.

As back pain is a long-lasting condition, that is present at all ages, studies covering a single year can only provide a snapshot of the whole picture, and may be missing vital information about the longer-term course.
