Introduction: Dementia is a more and more common cerebral disease. The number of people with dementia will increase in the coming years. People with dementia are often placed in the appropriate institutions. The home environment, by introducing some adaptations, represents a person with dementia supporting environments. Customized home environment enables enhanced safety, autonomy and greater engagement in life activities. Purpose: The purpose of diploma work was to determine the following: Have family members of dementia patients adapted their home environment, what strategies (adaptations) they used and which are the most common ones? How did they get the information about adaptations and who advised them? Does the adapted home environment support the autonomy and safety of a person with dementia? Methods: In the first part of the diploma work, the author examined the existing professional literature by analyzing and interpreting the text. In the second part of the diploma work, a qualitative study of the case was used as we compared the results obtained between them within one group. The instrument used was an interview. There were 10 partially structured and non-standardized interviews. Results: Based on a qualitative analysis, the following categories were formed: adaptation of the living environment and the surroundings, the source of information on adjustments, safety measures and the acceptance of professional assistance. The most commonly adapted rooms in the house are bathroom, bedroom and kitchen. The most commonly used adjustments are: sensor light, hospital bed, bedside fence, shower seat, non slip shower mat, handles next to a toilet, frequently used objects in a prominent place and locking sharp and dangerous objects. Discussion and conclusion: In the diploma work, we found that the home environment supports the person with dementia. With practical and inexpensive adaptations, we enable a person to be more easily involved in his or her life activities. By fulfilling the conditions of carrying out the activities, safety and autonomy, we influence the well-being and satisfaction and thus achieve a higher quality of life of the demented person. In the future, much remains to be done in the field of dementia. Knowledge about the disease itself has improved, but there are very few data on how to make life easier for the demented person in the home environment. An opportunity for modern medical professions, such as occupational therapy, arises here as it could provide a lot of advice and interventions in this field.
