![]() ![]() CONCLUSIONS:Findings suggest a specific association between doPTA-an acute injury phenomenon-and chronic memory deficits after TBI. SM was associated with memory performance, but unrelated to doPTA. Impairment in memory, but not PS or EF, was associated with a history of longer doPTA. RESULTS:DoPTA was significantly related to memory performance, even after covariate adjustment. Interrelationships between doPTA, objective memory functioning, and SM were assessed. DoPTA-memory associations were evaluated via linear modeling of doPTA with memory performance and clinical memory status (impaired/unimpaired), controlling for PS, EF, and demographic covariates. Composite memory, processing speed (PS), and executive functioning (EF) performance scores, as well as data on subjective memory (SM) beliefs, were extracted. METHODS:Participants were 82 individuals (median chronicity = 10.5 years) with available doPTA estimates and neuropsychological data. OBJECTIVE:To examine the relationship between doPTA and memory functioning, independent of other cognitive abilities, in chronic moderate-to-severe TBI. It is unclear whether duration of PTA (doPTA) uniquely impacts memory functioning in the chronic post-injury stage. ![]() Ībstract: BACKGROUND:Disrupted memory circuitry may contribute to post-traumatic amnesia (PTA) after traumatic brain injury (TBI).
