    Attention deficit hyperactivity disorder, or ADHD, is a commonly diagnosed childhood problem. However, ADHD-like symptoms are more common in young children with Down syndrome compared to children from the general population.

  2. Alzheimer's Disease & Down Syndrome

    Alzheimer’s disease and Down syndrome share a genetic connection, leading to the increased risk of dementia at an earlier age. Understandably, many families and caregivers are especially worried about this possibility, which is one reason why this topic is covered in detail in this section. Getting accurate information and education about the risk of Alzheimer’s disease is an important way of empowering oneself to prepare for the future.
