Currently, more than 1 in 10 adults living in the Organization for Economic Co-operation and Development is involved in nonprofessional care of a dependent family member. The main causes of dependence are dementia, followed by other conditions such as cerebrovascular accidents, limb impairment, depression, and vision impairment. Although care provided by the caregiver is crucial to the well-being of the cared person, it can also have negative consequences on the caregiver's emotional state. This chapter aims to describe the psychopathological symptoms experienced by caregivers based on the condition of the person cared for. A bibliographic search was conducted to examine the efects of care on the emotional state of caregivers, distinguishing patients with dementia from those with other conditions. Depressive and anxiety symptoms were the most frequent psychopathological symptoms, both in caregivers of demented and nondemented patients, experienced by caregivers of patients with dementia, cerebrovascular accidents, traumatic brain injury, schizophrenia, cancer, amyotrophic lateral sclerosis, and autism spectrum disorder. In caregivers of patients with bipolar disorder and vision impairment, depressive symptoms were most prominent, whereas anxiety symptoms were common in caregivers of patients with spinal cord injuries. Sleep disturbances were found among caregivers of dementia and schizophrenia patients. Strategies for preventing psychopathological symptoms were provided and the importance of professional support when they occur was pointed out.
