Old age is an inseparable part of human life. It is characterized by somatic, social and psychological changes that may affect patient's way of interaction with other people. The most common are attention disorders, inability to concentrace, hearing impairment and perception and memory disorders (Venglářová, Mahrová, 2006, s. 104). It is essential that nurses taking care of the patient have satisfactory knowledge about these factors and are able to adjust to the patient's abilities and thus reduce risk of misunderstandings (Pokorná, 2010, s. 10).
