This study was randomized controlled study conducted to determine the effect of Nihavent theme on reducing adjustment difficulties in Alzheimer's patients.

The study was carried out with 30 patients.15 patients constituted the experimental group and 15 patients formed the control group. Before the application, the scale was administered to both groups through face-to-face interviews. The patients in the experimental group were informed about the music session in advance.Instrumental songs in nihavent theme were played with the sound system to the experimental group. The sessions were lasted 12 weeks in total and there were two sessions per week, and each session took approximately 50 minutes to complete. While no intervention was performed for the patients in the control group. One week after the last music session, the the scale was re-administered to both groups.

Adaptation levels of Alzheimer's patients should be determined before planning nursing interventions. Institutions should support healthcare personnel in organizing music sessions for patients. It is believed that further studies examining the effect of the Nihavent theme in decreasing adaptation difficulty in Alzheimer's patients should be conducted with larger sample groups. The effects of verbal and non-verbal music on Alzheimer's patients should also be evaluated and compared to gain further insight on this important matter.
