If there is an obstacle or challenge you wish to include in the statement, mention it concisely and make it relatable to the context. Do not go into details. Some applications will provide applicants with an opportunity to discuss challenges that negatively impact their grades or work. If this is the case, provide this information in that section, which is usually separate from the statement. Avoid providing unjustified explanations as to why you achieved lower-than-expected grades or performance. They affect the reviewers’ impression of accountability.
