How long must an impairment last to meet the definition of disability?

To meet the definition of disability under Social Security Disability Insurance (SSDI), an impairment must last for at least 12 months. This duration requirement is significant because it establishes the severity and persistence of the condition. The Social Security Administration (SSA) uses this timeframe to determine whether individuals can engage in any substantial gainful activity due to their impairments.

By requiring that the impairment lasts for 12 months, the SSA aims to filter out temporary disabilities and focus on conditions that have a long-term impact on a person's ability to work and perform daily activities. This duration is part of a broader assessment that includes evaluating the nature of the impairment and its effect on the individual's functional abilities.
