Abstract Objective We investigated whether clock-checking frequency during a prospective memory (PM) task differed between Veterans with reported histories of blast-related mild traumatic brain injury (mTBI) and Veteran Controls (VCs) without a history mTBI. We hypothesized that, compared to controls, the mTBI group would less frequently clock check. Additionally, we expected that reduced clock-checking would contribute to poorer time-based PM performance in the mTBI group. Method Twenty-seven Veterans (9 mTBI and 18 VC) with sufficient effort testing completed a structured TBI history interview, the Post-Traumatic Stress Disorder Checklist (PCL) and the Memory for Intentions Test (MIST) as a PM task. During MIST administration, examiners recorded clock-checking behavior each time a participant physically turned a digital clock to observe the current time. Results Compared to VCs, the mTBI group performed worse on the Time subscale of the MIST [Mean (SD) VC = 6.7 (1.1), mTBI = 5.7 (1.1), p < .05], and demonstrated significantly fewer clock-checks over the duration of the test [VC = 14.2(4.7), mTBI = 10.2 (3.4), p < .05]. Clock-checking significantly correlated with MIST Time subscale performance (r = .38, p < .05). Groups did not significantly differ in PCL scores, and PCL scores did not significantly correlate with clock-checking counts. Conclusion Our preliminary results are the first to show that clock-checking behavior may contribute to reduced performance on time-based PM tasks in Veterans with histories of mTBI. Specifically, our findings demonstrate that participants with mTBI employ an inefficient time monitoring strategy wherein infrequent clock checking contributes to poorer test performance. These findings suggest that strategies to improve clock checking may improve PM performance.

Jelen tanulmány tudomásunk szerint az első magyar nyelvű áttekintés a prospektív emlékezet (prospective memory, PM) témájában, melynek kettős célja van. Egyrészt összefoglalja a PM legfontosabb fogalmait, elméleteit, kísérleti és idegtudományi eredményeit, ismertetve a kutatások klinikai relevanciáját. A PM a jövőbeli szándékokra irányuló emlékezet, egy olyan összetett kognitív képesség, amely alapvető a mindennapi feladataink ellátása során. Működése a prefrontális kéreghez és kapcsolataihoz köthető, így számos, a frontostriatális rendszert érintő kórkép esetén sérülést mutat. Áttekintésünk fókuszában egy gyakori neurológiai kórkép, a traumás agysérülés áll. E személyek hétköznapjait a leginkább megnehezítő, gyakori és tartós kognitív zavar a PM sérülése. Ennek ellenére kevés kutatás foglalkozott a csökkent PM-működést meghatározó tényezőkkel ebben a betegcsoportban, az eredmények pedig ellentmondásosak.Tanulmányunk további célja, hogy összefoglalja a traumás agysérült személyek PM-teljesítményével kapcsolatos empirikus kutatásokat. Szakirodalmi áttekintésünkben 25 empirikus tanulmányt azonosítottunk, amelyekben traumás agysérült felnőtt személyek PM-teljesítményét hasonlították össze egészséges kontrollszemélyekével. Az eredmények alapján megállapítható, hogy traumás agysérülést követően jellemző a PM diszfunkciója. Azonban számtalan tényező befolyásolhatja a PM-teljesítményt ebben a populációban: a sérülés súlyossága, lokalizációja, a kómában és a poszttraumás amnéziában töltött idő, a sérülés óta eltelt idő, a hangulatzavarok és a komorbid kognitív zavarok; valamint az olyan feladatjellemzők, mint a mérőeszköz típusa, a PM összetevői, illetve a prospektív kulcsinger és a folyamatban lévő feladat jellegzetességei. Elgondolásunk szerint e kutatási eredmények nemcsak a PM működésének megértésével kapcsolatban szolgálnak fontos következtetésekkel, hanem támpontokat adhatnak a rehabilitációs, terápiás munkára nézve is, megteremtve egy jövőbeli hatékony, a PM-funkciókra fókuszáló kognitív tréning kidolgozását traumás agysérült személyek számára.To the best of our knowledge, the present paper is the fi rst review in Hungarian on the topic of prospective memory (PM), and it has a dual objective. On the one hand, it summarizes the most important concepts, theories, experimental and neuroscientifi c results of PM, describing the clinical relevance of the research. PM refers to the memory for future intentions, and it is a complex cognitive ability that is essential in performing our day-to-day tasks. PM function is related to the prefrontal cortex and its connections, and its dysfunction is well-documented in several diseases affecting the frontostriatal system. This review focuses on traumatic brain injury, a common neurological disorder. Patients with traumatic brain injury experience PM dysfunction, which is a common and persistent cognitive disorder making their everyday life the most diffi cult. Nevertheless, little research has investigated the factors contributing to decreased PM performance in this patient population, and the results are contradictory.Another goal of our study is to summarize empirical research on PM performance after traumatic brain injury. In this literature review, we identifi ed 25 empirical studies comparing the PM performance of adults with traumatic brain injury with those of healthy controls. Based on these empirical results, PM dysfunction is a common fi nding after traumatic brain injury. However, a number of factors can affect PM performance in this population: the severity and localization of injury, time spent in coma, length of posttraumatic amnesia, time since injury, mood disorders and comorbid cognitive disorders, and task characteristics, such as the type of measurement, the components of the PM task, and features of the PM cue and the ongoing task. In our opinion, these fi ndings not only provide essential conclusions about understanding the functioning of PM, but they can also establish the foundation for rehabilitation and therapeutic work, and contribute to the creation of an effective cognitive training focused on PM for traumatic brain injury patients.

Prospective Memory Impairment

AbstractThis article aimed to review the assessment and treatment of prospective memory impairment in individuals with traumatic brain injury. The three assessment techniques reviewed included questionnaires, psychological tests, and experimental procedures. Because interest in this area is relatively new, not many assessment techniques have been specifically developed to assess the various constructs of prospective memory. Of these, most lack a firm theoretical basis, adequate norms, and strong psychometric properties. Rehabilitative techniques, based on remedial and compensatory approaches, were then evaluated. Intervention methods that show promise include a prospective memory training approach, diary or memory notebook use, and electronic aids. Nevertheless, there is a need for further controlled trials with larger sample sizes to more thoroughly evaluate these methods. Self-awareness of memory impairment and generalisation of gains from treatment are another two issues identified as important for assessing and treating prospective memory impairment.

AbstractThis study aimed to evaluate the influence of cognitive demand on prospective-memory in individuals with traumatic brain injury (TBI) using a dual-task paradigm. Fourteen individuals with severe TBI and 14 matched controls were required to undertake two tasks. A lexical-decision task was used as an ongoing task and had two levels of cognitive demand (viz., low and high). The event-based prospective-memory task involved performing a specific action whenever a target stimulus appeared during the ongoing task. The Letter-Number Sequencing Test, the Tower of London and the Controlled Oral Word Association Test were also administered to assess the relationship between prefrontal lobe functions and prospective memory. As hypothesised, participants in the TBI group performed more poorly than participants in the control group on the prospective-memory task in the high but not in the low demand condition. There were significant correlations between prospective-memory task performance and scores on the Letter-Number Sequencing Test and the Controlled Oral Word Association Test. These findings help to clarify the nature of prospective-memory impairment in individuals with TBI and support the involvement of prefrontal processes in prospective remembering.
