The aim of this study was to investigate caregiver stress among informaln caregivers of people with dementia and how it affects the informal caregiver himself through review of the existing literature on this topis. Caregiver stress occurs in the midst of several factors, such as environmental conditions, factors related to the care process itself, factors related to the sick person and personal factors of the caregiver himself. Caregiver stress has severe consenquences for informal carers. It causes physical and mental disabilities and negatively affects the social life of the informal caregiver. The profil of a typical informal caregiver refers to the daughter of the carereceiver in her middle or old age and the spouse of the carereceiver, mostly the wife. In most cases, the informal caregiver lives with the carereceiver,, caring about a carereceiver on a daily basis and perannial. Positive aspects of care, humor, spirituality, a fairer distribution of care among family members, the availability of resources and knowledge about dementia and its development act as resilience factors of the informal caregiver and reduce and/or prevent the occurence of caregiver stress. The help and support of experts, counseling, education, stress control training and emotional support are also very important for the caregiver.
