Understanding the Hidden Mechanisms Behind Mental Absence

People experiencing dissociation may feel numb, lose time, or mentally disconnect—yet these symptoms stem from distinct psychological processes. Research distinguishes between emotional numbing, detachment, compartmentalization, and sensory disconnection, each requiring different therapeutic approaches. Recognizing the specific mechanism is key to effective treatment.
In October 2026, mental health researcher Antonieta Contreras published an article titled “Understanding the Hidden Mechanisms Behind Mental Absence,” which examines dissociation not as a monolithic experience but as a spectrum of distinct psychological processes. The piece draws on clinical observations and neuroimaging research to distinguish four mechanisms: emotional numbing (described as "volume turned down"), compartmentalization ("connection missing"), shutdown (a system-wide response), and sensory disconnection—though the latter two remain less formally classified within diagnostic frameworks. Contreras emphasizes that while all may manifest as mental absence, their underlying causes and treatment needs differ significantly. The article references a decade-old proposal to split dissociation into detachment and compartmentalization, now expanded upon with real-world clinical examples: a woman describing her father’s death with emotional flatness, a man observing his own arguments from a distance, or individuals experiencing memory gaps during trauma recall. These cases illustrate how dissociative symptoms can stem from regulatory mechanisms meant to protect the mind under stress but become maladaptive when chronic.
The background lies in longstanding ambiguity around the term “dissociation,” which has been misused both by laypeople and professionals to describe a wide range of experiences—from emotional numbness to amnesia. Contreras critiques this conflation, arguing
This article could influence public understanding of trauma-related mental states by challenging the oversimplification of “dissociation” as a single phenomenon. By differentiating mechanisms like emotional numbing from compartmentalization, it may help reduce stigma and encourage more precise clinical assessments. Individuals experiencing dissociative symptoms—particularly survivors of abuse or PTSD—may benefit from tailored therapies that address specific processes rather than applying one-size-fits-all interventions. The broader impact may extend to mental health education, training programs for therapists, and insurance policies that recognize nuanced diagnoses. A comparable earlier case is the shift in understanding PTSD from a battlefield-only condition to a spectrum of responses across diverse traumas, which reshaped military and civilian care models. Here, the story may prompt similar evolution: if clinicians begin distinguishing mechanisms, it could lead to more effective trea
