However, the lack of a reliable and valid measures of caregiver impact and the characteristic pattern in Taiwan. The purpose of this study was to describe the characteristics of patients with DS and caregivers’ concerns, and to establish a baseline frequency of characteristics of the disease using a cross-sectional survey in Taiwan. We recruit the caregivers of patients with DS and assessed their condition via online anonymous questionnaire. Seizure frequency decreased with age though not statistically significant. Vaccine may not influence the condition of DS. We highlighted the greatest impact on the domains that affect caregivers’ daily life, including additional household tasks, symptoms observation, further medical plan and financial problem. Caregivers may also concern about lack of independence/constant care, seizure control, speech/communication and sibling impacts/long-term care when patents are gone. The current findings highlight the significant life effects of caring for a child with DS in Taiwan, and can be used to raise the attention about the need for these families. The possible pathogenic mechanisms of these comorbidities were also discussed.
