He previously worked as a police officer and sustained TBI and polytrauma in 1996 when he was assaulted on the job. Patient presented with a history of a single, developmentally unremarkable infant febrile seizure and unremarkable adolescence with no history of special needs education. He was alert and near baseline functioning during clinical presentation, but neuropsychological testing revealed several deficits.Ĭlinical history was recorded in conjunction with administration of neuropsychological assessments. This is atypical and unique because a damaged long-term episodic memory is typically associated with significantly higher functional impairments.Ī 53-year-old male with 15 years of education and a history of TBI presented in 2018 with an inability to recall 22 years of long-term episodic memories. This case report details a patient with TBI who is able to participate in activities of daily living while suffering from long-term episodic memory loss not attributable to dissociative identity disorder. However, determining the etiology of these disorders remains difficult and controversial. To our knowledge, few if any studies describe a case of localized dissociative and retroactive amnesia (as opposed to diffuse retroactive amnesia) that was not later attributed to dissociative identity disorder. Memory deficits have been previously characterized in the TBI literature however, most have described prospective memory impairment or other types of memory loss. Such deficits may manifest within the first 24 hours after trauma and can lead to severe, lasting decrements in both functional capabilities and quality of life. Traumatic brain injury (TBI) has been implicated in the development of a broad spectrum of pathologies including deficits in cognitive abilities such as executive function and memory. Traumatic brain injury, amnesia, memory loss The authors present this unique case’s profile, clinical history, and discuss their findings. Increased awareness and study of memory loss following TBI can contribute to enhanced understanding and improved care for patients experiencing these deficits. ![]() ![]() Although fully independent in activities of daily living, this patient demonstrated severe deficits in visual memory and processing speed upon neurocognitive evaluation. While memory loss due to TBI is present in the literature, presentations of this type are very rare. ![]() Repeat Traumatic Brain Injury Complications with Localized Dissociative Amnesia of Twenty-Two Years A B S T R A C TĪ 53-year-old male with history of traumatic brain injury (TBI) presented with localized dissociative amnesia following a second head injury.
