“…Moulton et al 2005), alcohol significantly impaired performance on the prose recall task, for both immediate and delayed recall. Furthermore, the positive correlation between irregular PM tasks and delayed recall, which primarily taps episodic remembering, stresses the central role of episodic memory in prospectively remembering to carry out infrequent tasks.…”

“…For example, state-dependent learning theory purports that habitual drinkers are able to retrieve information better when their physiological and sensory context is the same as during the encoding memory (Petersen 1977). Evidence for facilitated memory retrieval under the influence of alcohol has been mixed in human research (Duka et al 2001; Moulton et al 2005) and argues for a small effect on basic memory retrieval that does not readily transfer to more complicated memory or psychomotor tasks (Weissenborn and Duka 2003). Both groups improved on both tasks over time, so it is possible that repeated exposure to these tasks while under the influence of alcohol contributed to improved performance.…”

Alcohol-induced performance impairment: a 5-year re-examination study in heavy and light drinkers

Background The theory of behavioral tolerance to alcohol posits that greater experience with drinking to intoxication leads to less impaired cognitive and psychomotor performance. However, the degree to which behavioral tolerance develops or changes over time in adults due to repeated heavy alcohol drinking has not been clearly demonstrated. Method We examined data from the first 6 years of the Chicago Social Drinking Project to test whether chronic heavy drinkers (HDs; n = 86) and light drinkers (LDs; n = 69) exhibit behavioral tolerance or changes in perceived impairment at two testing phases in early adulthood. Tasks were the Grooved Pegboard and Digit Symbol Substitution Test (DSST) given at initial testing and then repeated in a re-examination phase 5 years later. Alcohol (0.8 g/kg) and placebo were administered at separate sessions in each phase for a total of 620 individual laboratory sessions. Results HDs exhibited less impairment over time on the Pegboard task but not on the DSST, while LDs did not exhibit behavioral tolerance on either task. HDs reported persistently lower perceived impairment compared to LDs. Conclusions These findings demonstrate that behavioral tolerance in HDs is evident over time on rote fine motor skills (Pegboard) but not more complex skills integrating motor speed, encoding, and short-term memory (DSST). The results have implications for our understanding of alcohol-induced impairments across neurobehavioral processes in heavy drinkers and their ongoing risks for alcohol-related consequences over time.

“…as the blood alcohol level increases, cognitive function and psychomotor • performance decrease rapidly (Easdon et al 2005); consumption of less than two standard drinks potentially results in effects that increase risk of injury (Tagawa et al 2000;Howland et al 2001;Marinkovic et al 2001;Marinkovic et al 2004;Moulton et al 2005;Breitmeier et al 2007) and driving ability is impaired at blood alcohol levels of about 0.05 per cent, a level reached after two or three standard drinks (Tagawa et al 2000) national health and medic al research council | 55 australian guidelines to reduce health risks from drinking alcohol…”

Objective: To determine the proportion of alcohol‐related presentations to emergency departments (EDs) in Australia and New Zealand, at a single time point on a weekend night shift. Design, setting and participants: A point prevalence survey of ED patients either waiting to be seen or currently being seen conducted at 02:00 local time on 14 December 2013 in 106 EDs in Australia and New Zealand. Main outcome measures: The number of ED presentations that were alcohol‐related, defined using World Health Organization ICD‐10 codes. Results: At the 106 hospitals (92 Australia, 14 New Zealand) that provided data, 395 (14.3%; 95% CI, 13.0%–15.6%) of 2766 patients in EDs at the study time were presenting for alcohol‐related reasons; 13.8% (95% CI, 12.5%–15.2%) in Australia and 17.9% (95% CI, 13.9%–22.8%) in New Zealand. The distribution was skewed left, with proportions ranging from 0 to 50% and a median of 12.5%. Nine Australian hospitals and one New Zealand hospital reported that more than a third of their ED patients had alcohol‐related presentations; the Northern Territory (38.1%) and Western Australia (21.1%) reported the highest proportions of alcohol‐related presentations. Conclusions: One in seven ED presentations in Australian and New Zealand at this 02:00 snapshot were alcohol‐related, with some EDs seeing more than one in three alcohol‐related presentations. This confirms that alcohol‐related presentations to EDs are currently underreported and makes a strong case for public health initiatives.
