Dementia is a type of a degenerative disease that affects approximately 36 million of the world's population. People with dementia experience worsening of cognitive function, communication problems, problems with expression and emotions, aggression, irritability and problems with sleep. These cognitive, psychosocial and behavioral symptoms have a negative impact on the functioning of the person with dementia, but also on family members and the wider community. Pharmacological and non-pharmacological methods may be used in the treatment of dementia. Non-pharmacological methods that have a particularly positive effect on the functioning of a person with dementia are music therapy and art therapy. The aim of this review paper is to present the basics of the use of music therapy and art therapy in the rehabilitation of people with dementia. In other words, to further explore the effectiveness of this therapy in treating symptoms and consequences of this disease. For that purpose, the examination of the existing literature and research has been conducted. It was seen how music therapy can positive impact on cognitive and communication skills, which is evident through improved ability to name and identify individuals after individual singing lessons, better verbal fluency and better memorization of texts with music. The effects of music therapy to psychosocial and emotional state are evident through increased calmness and well-being. The effects on behavioral state is evident through reduced sleep problems, reduced aggressive behavior and aimless wandering. Furthermore, people with dementia have a relatively preserved capacity for imagination and creativity. So the use of art therapy in the rehabilitation of people with dementia can affects on the development of creativity, spontaneity, encourages and develops communication, and contributes to a sense of great satisfaction. It has also been confirmed that it can improve the quality of life of patients and their caregivers and have the effect of reducing behavioral problems. Of all the benefits that art provides, one of the most important is a sense of connectedness or transcendence. That connection is essential for people with dementia because the user's relationship with others and their own identity is exposed to decay. Given these contributions, music therapy and art therapy represent appropriate complementary methods within an interdisciplinary system to support people with dementia.
