The psychological concepts of ‘ambiguous loss’ and ‘anticipatory grief’ describe complex emotional states occurring when a loved one is physically present but mentally or emotionally unreachable. Developed by Professor Pauline Boss, ‘ambiguous loss’ refers to situations lacking clear closure, such as when individuals are physically missing due to migration or kidnapping, or when they are cognitively unreachable due to dementia, brain injury, or severe mental illness.

In cases of progressive illness like dementia, this state is often accompanied by ‘anticipatory grief,’ a mourning process that begins before an actual death occurs. This involves grieving the loss of shared routines, intimacy, and future plans. This process affects both caregivers and patients, who may experience grief over their own changing identities and lost independence.
