To be covered by the definition of disability, a condition must have a “long-term” effect. An effect is “long-term” if it lasts for at least 12 months, or for the rest of a person’s life. Recurring conditions can amount to a disability, even if they appear to have gone away, provided they are likely to recur. In practice, this need for a condition to be “long-term” often excludes reactive work-related depression caused by adverse life events, such as redundancy, from the statutory definition of disability.
