The incidence of Alzheimer\u2019s disease (AD) increases with age, but parental longevity is often associated with better offspring health and lower AD risk. This study aimed to investigate the relationship between parental longevity and AD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We included patients with AD and cognitively healthy subjects (over 75 years), collecting family history data, namely maternal and paternal age at death. We performed a logistic regression to evaluate the association of parental longevity and AD risk and linear regression models for the association with age of onset and CSF biomarkers, adjusting for confounders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We analyzed 3069 participants from a Portuguese cohort, including 893 AD patients and 2176 cognitively healthy controls.
