For example, rates of depression between 12% and 59%
and anxiety between 30% and 50% have been reported in
samples of caregivers, in comparison to those of
depression between 10% and 25% and between 19% and
34% in the patient population. Additionally, between 40%
and 76% of cancer caregivers reported clinically significant
symptoms of insomnia, which negatively affect their
mental and physical health, are frequently chronic, and
may impair the normal grieving process among bereaved
caregivers. These symptoms can increase the risk for
chronic illness in caregivers, including cardiovascular
disease and cancer.
