The impossibility of self-care is often in the older age induced by diseases. Caring for a person with dementia has been described as the most demanding form of care because it requires intensive and long-term care. Given that currently about 35 million people are suffering from the same disease, whose expansion is only expected, it can be said that has great economic importance for society. The modern families, due to the demands of everyday life, are no longer able to provide adequate care, which has increased the need for formal care forms. Professional i.e. formal carers are experts of different professions who are faced with different challenges of a custodial relationship. The aim of this study was to gain insight into the challenges of working with people with dementia from the perspective of formal carers. In the qualitative study participated 15 caregivers from 4 different institutions in Zagreb with whom are conducted semi-structured interviews. The results of thematic analysis of the data showed that carers as work problems identified lack of understanding by family members and the organization of work. Besides, care exhausts them and evokes the feeling of helplessness. When we talk about the benefits of the work, the results show that in addition to emotional fulfilment and an increased sense of meaning and purpose in life, carers perceive as benefits personal growth for which they were given the opportunity as well as the acquired new point of view on the elderly. In conclusion, the study shows that further systematic research on carers are needed, in order to obtain guidance for further developing of the system which is very insufficient in Croatia in comparison to the existing needs.
