There is limited evidence examining the impact unpaid care has on both the physical and mental health of caregivers. Srivastava and colleagues (2016) examined the quality of life (QOL) and burden experienced by primary caregivers of people with dementia in Lucknow, Uttar Pradesh. The authors report that caregiver burden ranges from mild to moderate, but this burden affects the psychological, physical, social, and environmental QOL of caregivers. Similarly, Jathana and colleagues (2011) found caregiving to be associated with poor physical and mental QOL in a study conducted in India.
