Ultimately, 16 studies (13 in English and three in Persian) were selected for the final review. 
Results Two main categories of psychological problems and psychological needs emerged. Psychological problems consisted of six sub-themes: Neglecting personal needs and weakening of individual identity, interference of caregiving role with life and recreational activities, drowning in negative and unpleasant emotions, heavy caregiving burden and disruption of other life roles, lack of intimate relationships, decreased well-being and health, and sleep disturbances. The psychological needs included four sub-themes: Need for support, need to address mental health conditions, need for empathy and appreciation, and need for a temporary break from caregiving.
Conclusion The results contribute to a deeper understanding of the psychological problems and needs of caregivers of older adults and emphasize the necessity of paying more attention to their mental health. The findings can be useful in developing comprehensive supportive policies and programs for this group.
