IntroductionThe alcohol hangover state (AHS) is characterized by range of symptoms (e.g., drowsiness, fatigue, gastro-intestinal problems, dry mouth, nausea, sweating) that remain after ones blood-alcohol level returns to zero following a recent bout of excessive drinking. Recent findings have revealed a range of cognitive deficits associated with an AHS, including memory deficits. It is less clear what impact the AHS has upon everyday remembering; of which prospective memory is an excellent example (PM: memory for future plans/actions; such as remembering to perform a task at a specific time).AimsThe present study explored whether the AHS impairs everyday PM.MethodsTwenty-one AHS participants were compared with 28 non-AHS controls using a between-groups design. All completed a prospective remembering video procedure (prvp), which measured event-based pm. the prvp required the participant first to memorise a series of specific action-locations combinations and then to recall these combinations whilst viewing a CD clip of a busy shopping high street. Drug use (alcohol, smoking, etc.) and mood (anxiety and depression) were also measured, as these have been shown to have a deleterious impact upon PM.ResultsThe AHS group recalled significantly fewer event-based PM combinations on the PRVP compared with the non-AHS control group (P < 0.05). There were no significant differences between the groups on age, smoking, alcohol use or mood.ConclusionThese results confirm that a state of alcohol hangover impedes everyday prospective memory. The wider implications will be discussed at conference.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

Prospective Memory Performance

The aim of this study was to investigate the extent to which the retention interval between intention formation and the execution of the action affects the occurrence of remembering and its accuracy. 126 subjects (48 men and 78 women) between 18 and 24 years participated in a two-phase experiment. An event-based prospective memory task was assigned at the end of the first experimental session, which required reporting a message to the second experimenter at the beginning of the second experimental session. The length of the interval of time between the formation of the intention and its execution varied (10 minutes, 2 days, 2 weeks). Participants were randomly assigned to the three conditions (42 each). A post-experimental interview was carried out in order to find out the strategies that subjects employed to retrieve the message and the importance they attributed to the task. Results indicate that the delay affected neither the occurrence of remembering nor its accuracy, and that the importance attributed to the planned action improved the likelihood of prospective remembering. Furthermore, results seem to indicate that external reminders do not improve prospective memory. Further implications of the finding were discussed.

Objectives:To assess the sensitivity of patients who suffered a severe closed-head injury to the manipulation of attentional resources and encoding instructions during the execution of prospective memory tasks.Material and Methods:A group of patients with chronic sequelae of severe closed-head injury and a group of matched normal controls were given an experimental procedure for the assessment of time-based and event-based prospective memory. Availability of attentional resources at the time of intention recall and encoding conditions at the time of giving instructions were varied across experimental sessions.Results:The simultaneous execution of a concurrent task was more detrimental to accuracy in the spontaneous recall of the prospective intention in the post-traumatic than in the normal control group. Moreover, the instruction to encode more extensively by rehearsing aloud and mentally imaging the actions to be performed at the time of the study improved recall accuracy more in the post-traumatic than in the normal control group.Conclusions:Based on these data, we suggest that a prospective memory deficit in post-traumatic patients is due, among other things, to reduced availability of attentional resources and to poor encoding of actions to be performed.

Objectives: Patients with subcortical ischemic vascular disease (SIVD) often have prominent frontal dysfunction. However, it remains unclear how SIVD affects prospective memory (PM), which strongly relies on the frontoparietal network. The present study aimed to investigate PM performance in patients with early stage SIVD as compared to those with Alzheimer's disease (AD) and to older adults with normal cognition, and to explore the neural correlates of PM deficits.Method: Patients with very-mild to mild dementia due to SIVD or AD and normal controls (NC) aged above 60 years were recruited. Seventy-three participants (20 SIVD, 22 AD, and 31 NC) underwent structural magnetic resonance imaging (MRI), cognitive screening tests, and a computerized PM test. Sixty-five of these participants (19 SIVD, 20 AD, and 26 NC) also received resting-state functional MRI.Results: The group with SIVD had significantly fewer PM hits than the control group on both time-based and non-focal event-based PM tasks. Among patients in the very early stage, only those with SIVD but not AD performed significantly worse than the controls. Correlational analyses showed that non-focal event-based PM in SIVD was positively correlated with regional homogeneity in bilateral superior and middle frontal gyri, while time-based PM was not significantly associated with regional homogeneity in any of the regions of interest within the dorsal frontoparietal regions.Conclusions: The findings of this study highlight the vulnerability of non-focal event-based PM to the disruption of regional functional connectivity in bilateral superior and middle frontal gyri in patients with SIVD.

The Impact

Objectives. Prospective memory (PM) consists of remembering to perform an action that was previously planned. The recovery and execution of these actions require attentional resources. Mindfulness, as a state or a dispositional trait, has been associated with better attentional abilities. In this study, we investigated the impact of mindfulness on PM. Methods. Eighty participants learned 15 cue-action associations. They were, then, asked to recall the actions at certain moments (time-based items) or places (event-based items) during a walk in a virtual town. Before the PM task, participants were randomly assigned to a mindfulness or mind-wandering (control condition) session. Dispositional mindfulness was measured via the Five Facets Mindfulness Questionnaire (FFMQ). Results. We found no difference between the two groups in the PM scores. Nevertheless, the natural tendency to describe one's own sensations (the Describing facet of the FFMQ) predicted time-based performance in both groups. Conclusions. To our knowledge, this study is the first to explore the link between mindfulness and PM. We did not report any effect of a short mindfulness session, compared to mind-wandering, on PM. We discuss different hypotheses to explain this finding. Our main observation is a positive link between the Describing facet and time-based PM performances. We propose that this link could be due to the common association of this mindfulness facets and PM with attentional and interoceptive abilities. Additional studies are needed to explore this hypothesis.
