How Older Parents May Influence Their Children's Aging, Lifespan, and Risk of Brain Diseases

Updated

Abstract

Advanced parental age is associated with increased risks of congenital anomalies and neurodevelopmental dysfunction in offspring.

  • Advanced parental age (APrA) is defined as 35 years or older for mothers and 40 years or older for fathers.
  • APrA may impact offspring healthspan, leading to a higher likelihood of premature mortality.
  • Children of older parents could face increased risks of metabolic dysfunction.
  • There is a potential link between APrA and neurodegenerative diseases in descendants.
  • APrA supports the concept of an 'intergenerational clock' that connects reproductive timing with aging patterns in future generations.
