      abstract     = {We report on a 47-year-old female patient who was diagnosed
                      with a complex dissociative disorder, including dissociative
                      identity disorder (DID) and dissociative amnesias in
                      everyday life. Dissociative amnesias represent a major
                      challenge for patients, as they reduce coherence in everyday
                      experience and are accompanied by an impaired sense of
                      agency. The neurobiological background of dissociative
                      amnesia has been little researched, and therapeutic options
                      specifically targeting this symptom are rare. In a photo
                      elicitation interview, the patient reports of amnesias
                      regarding her past, but also of time gaps in everyday life.
                      To structure her experience of time, she reports of taking
                      up to 200 photos of her immediate surroundings with her
                      phone every day, which she regularly reviews in the evening.
                      As an outcome, reviewing these photos provides a structuring
                      frame for her everyday memory, reduces symptoms of perceived
                      time gaps, and thereby increases her reported sense of
                      agency. In addition, the photographic motifs also provide
                      insights into the processing of dissociative experiences,
                      e.g., regarding feelings of fragmentation and disruption.
                      Furthermore, MRI-data of the patient were analysed and
                      results are compatible with overall volume increases of the
                      hippocampus following pattern completion tasks (specifically
                      in CA2/3 subfields), and reduced volumes in CA1 subfields,
                      as previously reported in patients with dissociative
                      amnesia. The case report stresses the usefulness of
                      photographs in complex dissociative disorders, as a
                      complementary diagnostic tool regarding dissociative states
                      and as a therapeutic method against dissociative amnesias.
                      An involvement of the hippocampus is suggested but needs
                      further scientific exploration.},
