Binge Drinking in Young University Students Is Associated with Alterations in Executive Functions Related to Their Starting Age. PLoS One 2016; 11:e0166834. [PMID: 27861563 PMCID: PMC5115818 DOI: 10.1371/journal.pone.0166834] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2016] [Accepted: 11/06/2016] [Indexed: 11/26/2022] Open
Abstract
Our aim was to evaluate whether or not alcohol consumption in the form of binge drinking is associated with alterations of memory and executive functions in a population of university students. At the same time, we have studied the role of potential modulating factors, such as the APOE genotype or physical exercise.University students enrolled in academic year 2013–2014 at Escuelas Universitarias Gimbernat-Cantabria, affiliated with the University of Cantabria, were invited to participate in the study. We gathered sociodemographic data and details regarding the lifestyle of 206 students (mean age 19.55 ± 2.39; 67.5% women). We evaluated memory and executive functions via a series of validated cognitive tests. Participants were classified as binge drinkers (BD) and non-BD. Using Student's t-distribution we studied the association between cognitive tests and BD patterns. Multivariate analyses were carried out via multiple linear regression. 47.6% of the students were found to be BD. The BD differed significantly from the non-BD in their results in the executive functions test TMT B (43.41 ± 13.30 vs 37.40 ± 9.77; p = 0.0003). Adjusting by age, sex, academic records, age at which they started consuming alcohol, cannabis consumption, level of physical activity and other possible modifying variables, the association was statistically significant (p = 0.009). We noticed a statistically significant inverse correlation (Pearson’s r2 = -0.192; p = 0.007) between TMT B and starting age of alcohol consumption. Differences were observed in another executive functions test, TMT A, but only in the group of women (19.73±6.1 BD vs 17.78±5.4 non-BD p = 0.05). In spite of the young age of our participants, BD was associated with a lower performance in the executive functions test (TMT B). These deficits were related to the age at which they started drinking alcohol, suggesting an accumulative effect.

Siegel JA, Craytor MJ, Raber J. Long-term effects of methamphetamine exposure on cognitive function and muscarinic acetylcholine receptor levels in mice. Behav Pharmacol 2010; 21:602-14. [PMID: 20729719 PMCID: PMC2990349 DOI: 10.1097/fbp.0b013e32833e7e44] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/01/2023]
Abstract
Exposure to methamphetamine during brain development impairs cognition in humans and rodents. In mice, these impairments are more severe in females than males. Genetic factors, such as apolipoprotein E genotype, may modulate the cognitive effects of methamphetamine. Methamphetamine-induced alterations in the brain acetylcholine system may contribute to the cognitive effects of methamphetamine and may also be modulated by apolipoprotein E isoform. We assessed the long-term effects of methamphetamine exposure during brain development on cognitive function and muscarinic acetylcholine receptors in mice, and whether apolipoprotein E isoform modulates these effects. Mice expressing human apolipoprotein E3 or E4 were exposed to methamphetamine (5 mg/kg) or saline once a day from postnatal days 11-20 and behaviorally tested in adulthood. Muscarinic acetylcholine receptor binding was measured in the hippocampus and cortex. Methamphetamine exposure impaired novel location recognition in female, but not male, mice. Methamphetamine-exposed male and female mice showed impaired novel object recognition and increased number of muscarinic acetylcholine receptors in the hippocampus. The cognitive and cholinergic effects of methamphetamine were similar in apolipoprotein E3 and E4 mice. Thus, the cholinergic system, but not apolipoprotein E isoform, might play an important role in the long-term methamphetamine-induced cognitive deficits in adulthood.

Wilhelm J, von Ahsen N, Frieling H, Hillemacher T, Bayerlein K, Bönsch D, Ziegenbein M, Kornhuber J, Bleich S. Apolipoprotein E4 genotype is not associated with short-term cognition deficits during alcohol withdrawal. Alcohol 2005; 37:151-6. [PMID: 16713503 DOI: 10.1016/j.alcohol.2006.01.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2005] [Revised: 01/17/2006] [Accepted: 01/17/2006] [Indexed: 10/24/2022]
Abstract
Aim of this prospective study was to investigate a possible association between the apolipoprotein E4 (ApoE4) genotype and clinically well-known cognition deficits during alcohol withdrawal. We examined 172 patients with alcohol dependence (137 men, 35 women) during withdrawal treatment. The ApoE genotype was determined in all patients using polymerase chain reaction. Cognitive function was assessed applying the c.I.-Test on day 0 (admission) and on day 7 of withdrawal treatment. Using Pearson's chi2 test we found no significant association between the ApoE4 genotype and cognition deficits for both dates (day 0: p=.463; day 7: p=.760). Moreover, multivariate logistic regression analyses revealed no significant association between presence of the ApoE4 allele and cognitive dysfunction. Even though ApoE4 plays an important role in alcoholism-related brain atrophy and cognition deficits in demented as well as in nondemented healthy elderly people, this study provides no evidence for an association with short-term cognition deficits during alcohol withdrawal.
