Grief is a normal reaction to loss that everyone experiences differently. There are typically five stages of grief: denial, anger, bargaining, depression, and acceptance. Grief can occur due to death, but also other life changes like moves, job changes, relationship endings, or medical diagnoses. Alzheimer's disease causes grief for both the person diagnosed and their caregivers as abilities are lost over time. While grief takes time, seeking social support can help people move through the process in a healthy way.
