Childhood Amnesia

Childhood amnesia, also called infantile amnesia, is the inability of adults to retrieve episodic memories (memories of situations or events) before the age of two to four years, as well as the period before the age of ten of which adults retain fewer memories than might otherwise be expected given the passage of time.

  • Childhood Sexual, Emotional, and Physical Abuse as Predictors of Dissociation in Adulthood
    by Mary-Anne Kate on August 6, 2021

    This Australian study explores a person's self-reported exposure to childhood abuse to identify the characteristics that are predictive of clinical levels of dissociation in adulthood. The final sample comprised 303 participants, including 26 inpatients and outpatients (24 females and two males) receiving treatment for a dissociative disorder (DD), and 277 university participants, including 220 controls (186 females, 34 males), 31 with elevated levels of dissociation consistent with a DD or...

  • Informed Care for the Gynecologic Day Surgical Patient with a History of Sexual Trauma
    by Michele Troutman on July 24, 2021

    The field of Obstetrics and Gynecology is one that provides intersections between one's most private and intimate moments with scenarios that could potentially trigger significant emotional trauma. As providers, one must balance providing appropriate care with the respect and autonomy of the patient. The perioperative and operative space presents many ethical dilemmas in navigating these boundaries, particularly among individuals with a history of sexual trauma. In our commentary, we present one...

  • A neurostructural biomarker of dissociative amnesia: a hippocampal study in dissociative identity disorder
    by Lora I Dimitrova on June 24, 2021

    CONCLUSION: We propose decreased CA1 volume as a biomarker for dissociative amnesia. We also propose that traumatisation, specifically emotional neglect, is interlinked with dissociative amnesia in having a detrimental effect on hippocampal volume.

  • The memory for words: Armand Trousseau on aphasia
    by Richard Leblanc on June 11, 2021

    Of all the nineteenth-century physicians whose names still resonate today, Armand Trousseau is perhaps the one most familiar, for his description of carpal spasm as a sign of hypocalcemia (Trousseau's sign) and his description of the hypercoagulable state associated with cancer (Trousseau's syndrome). In the last three years of his life, Trousseau turned his attention to aphasia, which he included in his 1864 and 1865 lectures given at Hôtel-Dieu Hospital in Paris and which he discussed in an...
