DSRD increases demands on caregivers, to sleep disturbances, financial distress, and negative impacts on caregiver-reported social connections and perceived social support. The goal of this study was to characterize the caregiver-reported impacts of DSRD on social relationships by comparing their experiences to those of caregivers of individuals with DS and other neurological disorders (DSN).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Design\/methods<\/jats:title>\n                    <jats:p>This is a narrative burden-of-care study, not a network study. Using cross-sectional study design, caregivers of individuals with DSRD (n\u2009=\u2009228) and DSN (n\u2009=\u2009137) were recruited from a neurology clinic and a DSRD Facebook support group. Participants completed the DSRD Caregiver Distress Survey (CDS), which included four qualitative, open-ended questions focused on self-perception of adult friendships, social relationship impact, spouse\/partner impact, and perceived shrinkage of social world. Responses were analyzed using thematic coding; resulting theme frequencies summarize caregiver-reported perceptions and narratives and do not represent objectively measured social network structure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In the DSRD cohort, a high-level overview revealed that 65.66% of responses reported a negative impact on adult friendships, while 71.21% reported a negative impact on social relationships. A negative impact on spouse\/partner relationships was reported in 51.53% of responses, and a perceived shrinkage of social world was found in 52.82%. Caregivers in the DSRD group were significantly more likely to report \u201cSocial Withdrawal and Isolation\u201d (43.2% vs. 17.9%, p\u2009=\u20090.006), \u201cLoss of Community Participation and\/or Support\u201d (16.7% vs 4.5%, p\u2009=\u20090.043) and a \u201cPerceived Enduring Loss of Social Connections\u201d (35.3% vs. 8.7%, p\u2009=\u20090.002) compared to the DSN group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study\u2019s findings reveal a significant and complex process of perceived social disengagement among caregivers describing social withdrawal and loss of social connections that they experienced as enduring. The results emphasize the need for early interventions that address the individual\u2019s needs but also address the caregiver\u2019s social and mental health to prevent perceived long-term social isolation.<\/jats:p>\n
