Caregiving is the regional variation of caregiving practices as distinguished among countries. Examples include caregiving, continued treatment, hospice care, and physician-assisted suicide. Studies found an increased mortality of caregiving spouses. Current treatments can be divided into pharmaceutical, psychosocial and caregiving. Oxytocin, released in response to stressors, may be the mechanism underlying the female caregiving response. At the same time, older persons can make contributions to society including caregiving and volunteering. Infants often develop resistant attachment when the parents are inconsistent in their caregiving. The complex thought as required by caregiving can ward off cognitive decline. Furthermore, an awareness of the limitations of empathic accuracy is prudent in a caregiving situation. The ABC intervention aims to enhance caregiving sensitivity and decrease frightening behavior. They are thus liable to develop a pattern of compulsive caregiving in later life. As discussed above, there are benefits to the caregiving experience. This allows them to be more effective in their caregiving roles. There is initial evidence that caregiving and attachment involve both unique and overlapping brain regions. This provides experimental research on the emphasis on caregiving effecting attachment.
