Regular Caffeine Intake Delays REM Sleep Promotion and Attenuates Sleep Quality in Healthy Men.

J Biol Rhythms 2021 May 23:7487304211013995. Epub 2021 May 23.

Centre for Chronobiology, Psychiatric Hospital of the University of Basel, Basel, Switzerland.

Acute caffeine intake can attenuate homeostatic sleep pressure and worsen sleep quality. Caffeine intake-particularly in high doses and close to bedtime-may also affect circadian-regulated rapid eye movement (REM) sleep promotion, an important determinant of subjective sleep quality. However, it is not known whether such changes persist under chronic caffeine consumption during daytime. Read More

Caffeine supplementation in the hospital: Potential role for the treatment of caffeine withdrawal.

Food Chem Toxicol 2021 Apr 28;153:112228. Epub 2021 Apr 28.

Cardiovascular Division, Department of Medicine, University of Miami Leonard M. Miller School of Medicine, Miami, FL, USA. Electronic address:

Caffeine use in the population is widespread. Caffeine withdrawal in the hospital setting is an underappreciated syndrome with symptoms including drowsiness, difficulty concentrating, mood disturbances, low motivation, flu-like symptoms, and headache. Withdrawal may occur upon abstinence from chronic daily exposure at doses as low as 100 mg/day and following only 3-7 days of consumption at higher doses. Read More

The impact of daily caffeine intake on nighttime sleep in young adult men.

Sci Rep 2021 Feb 25;11(1):4668. Epub 2021 Feb 25.

Centre for Chronobiology, Psychiatric Hospital of the University of Basel, Basel, Switzerland.

Acute caffeine intake can delay sleep initiation and reduce sleep intensity, particularly when consumed in the evening. However, it is not clear whether these sleep disturbances disappear when caffeine is continuously consumed during daytime, which is common for most coffee drinkers. To address this question, we investigated the sleep of twenty male young habitual caffeine consumers during a double-blind, randomized, crossover study including three 10-day conditions: caffeine (3 × 150 mg caffeine daily), withdrawal (3 × 150 mg caffeine for 8 days, then switch to placebo), and placebo (3 × placebo daily).

Caffeine consumption, toxicity, tolerance and withdrawal; shared genetic influences with normative personality and personality disorder traits.

Exp Clin Psychopharmacol 2020 Nov 30. Epub 2020 Nov 30.

Department of Mental Disorders.

Our main aim was to estimate the extent of overlapping etiology between caffeine consumption and response and normative and pathological personality. Linear mixed-effects models were used to identify normative personality domains and personality disorder (PD) traits for inclusion in multivariate twin analyses together with individual caffeine related measures. Data were obtained from Norwegian adult twins in a face-to-face interview conducted in 1999-2004 as part of a population-based study of mental health and through self-report in 2010-2011 and 2015-2017.

The enhancing effect of 200 mg caffeine on mnemonic discrimination is at best small.

Memory 2020 08 17;28(7):858-869. Epub 2020 Aug 17.

Department Psychology, University of Cologne, Cologne, Germany.

Mnemonic discrimination is the ability to discriminate among similar memories, which requires separable representations of similar information. The neurocomputational process that assumedly decorrelates representations during encoding and consolidation is referred to as pattern separation. Deficits in pattern separation contribute to age-related declines in mnemonic functioning, which has motivated the development of targeted interventions. Read More

The Ambiguous Role of Caffeine in Migraine Headache: From Trigger to Treatment.

Nutrients 2020 Jul 28;12(8). Epub 2020 Jul 28.

Department of Sensory Organs Examination, Faculty of Health Sciences, Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University, M. Curie 9, 85-090 Bydgoszcz, Poland.

Migraine is a chronic disorder, and caffeine has been linked with migraine for many years, on the one hand as a trigger, and on the other hand as a cure. As most of the population, including migraineurs, consume a considerable amount of caffeine daily, a question arises as to whether it influences their headaches. Indeed, drinking coffee before a migraine attack may not be a real headache trigger, but a consequence of premonitory symptoms, including yawning, diminished energy levels, and sleepiness that may herald a headache.

Caffeine as a tool for investigating the integration of Cdc25 phosphorylation, activity and ubiquitin-dependent degradation in .

Cell Div 2020 29;15:10. Epub 2020 Jun 29.

Department of Chemistry and Molecular Biology, University of Gothenburg, Box 462, Gothenburg, SE- 405 30 Sweden.

The evolutionarily conserved Cdc25 phosphatase is an essential protein that removes inhibitory phosphorylation moieties on the mitotic regulator Cdc2. Together with the Wee1 kinase, a negative regulator of Cdc2 activity, Cdc25 is thus a central regulator of cell cycle progression in . The expression and activity of Cdc25 is dependent on the activity of the Target of Rapamycin Complex 1 (TORC1). Read More

Drug Alcohol Depend 2020 07 8;212:108024. Epub 2020 May 8.

University of Auckland, New Zealand.

Background: Anecdotal evidence suggests consumers of caffeine self-administer strategies to reduce consumption, but little is known of what these strategies are or how they are implemented.

Caffeine enhances sustained attention among adolescents.

Exp Clin Psychopharmacol 2021 Feb 21;29(1):82-89. Epub 2020 May 21.

Department of Psychology.

Despite the growing interest in caffeine use and its effects among adolescents, and a large literature on caffeine and attention among adults, there is a lack of experimental work examining the impact of caffeine on sustained attention among adolescents. We evaluated the acute effects of caffeine (vs. placebo) during a long (33-min) classic vigilance task among 31 adolescents (aged 12-17; 15 female; median caffeine use = 28 mg/day). Read More

Inconsistency in the Ergogenic Effect of Caffeine in Athletes Who Regularly Consume Caffeine: Is It Due to the Disparity in the Criteria That Defines Habitual Caffeine Intake?

Nutrients 2020 Apr 15;12(4). Epub 2020 Apr 15.

Centre for Sport Studies, Rey Juan Carlos University, 28942 Fuenlabrada, Spain.

Caffeine is the most popular psychoactive substance in the world, and data suggests that it is widely used by athletes before competition to enhance physical and mental performance. The high number of athletes that regularly use caffeine suggests the need to investigate the effect of acute caffeine ingestion in athletes habituated to caffeine. However, most of the studies supporting this claim have used samples of athletes who do not consume caffeine on a regular basis, and with caffeine intake withdrawal prior to the experiments.

Chronic voluntary caffeine intake in male Wistar rats reveals individual differences in addiction-like behavior.

Pharmacol Biochem Behav 2020 04 24;191:172880. Epub 2020 Feb 24.

Department of Psychiatry, University of California San Diego, School of Medicine, MC 0714, La Jolla, CA 92093, United States of America. Electronic address:

Caffeine is the most widely consumed psychoactive substance in the world. However, there is controversy about whether becoming addicted to caffeine is possible and a lack of well-established animal models to examine caffeine consumption. The present study sought to establish a model of caffeine consumption in Wistar rats, identify different rat populations based on caffeine preference, and determine whether extended voluntary caffeine consumption produces compulsive-like caffeine intake and withdrawal symptoms.
