What Does “Ambiguous Loss” Mean?

By Hal Lewis • December 5, 2025
My daughter, currently nearing completion of a graduate program in counselling, recently introduced me to the term “ambiguous loss”. This term applies to a loss that is unclear and lacks certainty, leaving family members and close friends feeling stuck because it is so difficult to mourn or find closure. One type of ambiguous loss is when the person is physically present but psychologically absent because their personality, memory, cognition, or emotional connection has been altered. Examples might include a family member with dementia, a progressive disease, a severe emotional disorder, or substantial brain injury. A second type of ambiguous loss is when the person is psychologically present but physically absent. This could include a missing person due to a natural disaster, a long- term incarceration, a kidnapping, or severe estrangement from the family. This type of loss can lead to intense confusion, frozen grief, and a prolonged sense of helplessness.

Marchell’s Story

By Dan Lewis Foundation • December 2, 2025
Marchell is an engaging and energetic middle-aged man who was enthusiastic about being interviewed for the DLF newsletter. He is an activist working to promote the rights and well-being of persons in the brain injury community, with a particular emphasis on helping persons with brain injury who are incarcerated or have been released from prison. Marchell is a successful businessman, proud of the company he co-founded--the Association of Young Business Owners (AYBOS), a marketing company in the Denver, Colorado area. He also works for Well Power (Denver’s Mental Health Center system) as a Zero Suicide Certified Peer and Family Specialist.  Marchell is clearly a man on the move to get a lot of positive things done. But this wasn’t always the case. Marchell spent much of his younger adult life incarcerated himself for a variety of crimes including robbery and assault. He had a history of recidivism following multiple releases.
