**Lifespan Integration** (LI) is a therapeutic method developed by American psychologist **Peggy Pace** since 2003. It combines elements of visualization, neuroscience of trauma, and Ericksonian hypnosis to integrate traumatic memories by connecting them with the client's complete life timeline.
**Core premise**: Trauma—especially early trauma—leaves the client with the implicit feeling that 'the past is still present.' The implicit memory of trauma lacks a time stamp: it is not experienced as 'this was, it happened, it ended,' but rather as 'this is, it is happening now.' LI restores the sense of temporal continuity through a specific exercise called the **'timeline'**.
**Clinical procedure**: The client creates a timeline of their life with significant events year by year. During the session, they briefly contact the original traumatic memory and then, guided by the therapist, quickly move through the timeline from that moment to the present, evoking an anchor for each year. The repetition of this journey (5-10 times) neurologically integrates the trauma into the biographical continuity.
**Validation**: LI has a smaller evidence base than EMDR or SE, but growing studies show efficacy for early trauma and dissociation. It is especially useful for pre-verbal trauma where no explicit narrative is available.
**Compatibility with systemic work**: LI can be applied before Family Constellations (to stabilize the client first) or after (to integrate systemic work into the biographical timeline). It is especially useful when systemic work has activated old traumatic material that requires temporal integration.
Evidence and contemporary voices
Lifespan Integration (LI) is a psychotherapeutic method developed by Peggy Pace in the early 2000s, specifically designed for the treatment of complex trauma and post-traumatic stress disorder (PTSD). The approach is based on the premise that integrating fragmented traumatic memories with the complete temporal narrative of one's life facilitates trauma resolution. Although LI has gained clinical adoption in contexts of early and pre-verbal trauma, empirical evidence remains limited. Recent studies (Pace, 2009; Wolynn, 2015) document clinical applications, but rigorous controlled research is scarce compared to therapies like EMDR or TF-CBT. Van der Kolk's (2014) research on the neurophysiology of trauma theoretically supports the need for temporal integration of fragmented memories, though it does not specifically validate LI. Institutions like the Trauma Center in Boston have explored similar narrative integration mechanisms, but without randomized controlled trials demonstrating LI's superiority over standard evidence-based treatments.

Notes and Open Debates
Lifespan Integration lacks randomized controlled clinical trials with methodological quality comparable to EMDR or Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). Most available literature comes from publications by Pace herself or clinical practitioners without rigorous independent peer review. No neuroimaging studies exist that demonstrate specific brain changes attributable to LI. Its applicability to pre-verbal trauma, though theoretically plausible, has not been validated through controlled experimental designs. Comparatively, therapies such as EMDR (Shapiro, 1989) and TF-CBT have decades of robust empirical research. The integration of LI into conventional mental health protocols remains marginal, and organizations such as the American Psychological Association do not include it in evidence-based treatment guidelines for PTSD.

Therapeutic method by Francine Shapiro (1989) that uses bilateral stimulation (eye movements, alternating taps) to reprocess traumatic memories. Empirically validated as a treatment of choice for PTSD.

Two distinct memory systems: implicit (procedural, emotional, somatic) operates without awareness. Explicit (autobiographical, narrative) requires conscious recall. Early trauma remains predominantly implicit.

A key brain structure for explicit memory and the temporal integration of experiences. In trauma, its function can be inhibited, leaving memories 'frozen' outside of narrative time.
