Does Reduced Emotional Brain Reactivity After Alcohol Show Better Judgment?
A 49-person imaging study found reduced responses to emotional faces in parts of the extended amygdala. It did not demonstrate less anxiety, improved threat judgment or preserved driving performance.
Can Alcohol Reduce Lottery Risk-Taking While Impairing Working Memory?
A small crossover study found more conservative reward choices alongside poorer demanding working-memory performance. Choosing a sure reward did not establish safer driving or preserved executive function.
Did a Ketone Supplement Lower Alcohol Levels Without Proving Better Driving?
A ten-person crossover trial found lower breath and reported blood alcohol levels after a ketone drink. It did not demonstrate restored driving ability or faster elimination, and several subjective outcomes were unchanged.
After Drinking Following a Crash, Can a Later Interview Yield More Remembered Details?
A 60-person film experiment found more recalled details at a later session in those who drank after viewing. There was no significant alcohol-placebo difference at either session, and the design did not establish that drinking improves testimony.
Does a Wrist Sensor’s BAC Display Validate Its Blood-Alcohol Estimate? An Eight-Volunteer Modeling Study
A prototype wrist sensor and skin-diffusion model illustrate how assumptions shape estimated BAC. Fitting skin data is different from validating estimates against simultaneous blood measurements.
Can Beliefs About Self-Control Change Alcohol’s Effect on a Stop-Signal Test?
Two experiments separated beliefs, drinking behavior and laboratory stopping ability. A reassuring message did not reduce subsequent drinking and did not protect stop-signal performance.
Does Drinking After Learning Improve Motor Memory? A 24-Person Study Found No Benefit
Alcohol after learning did not improve next-day retention of a reaching adaptation. Preserved adaptation also coexisted with poorer endpoint accuracy during intoxication, limiting claims about normal coordination.
Can Strong Sober Executive Skills Prevent Alcohol-Related Failures to Remember an Intention?
In 52 men, acute alcohol reduced performance on a delayed-intention test. Baseline executive skills predicted some specific changes, but did not explain the overall decline or establish protection for an individual driver.
Does Alcohol Make Every Face Look More Hostile? An 84-Person Crossover Study
An alcohol experiment found no overall increase in hostile face judgments, alongside effects for happy and ambiguous expressions. These findings do not establish aggression or driving impairment in an individual.
Alcohol With Dinner: Why Stimulation, Sleepiness and Mood Are Different Findings
A controlled dinner study found early stimulation alongside sedation after alcohol. Pleasant surroundings changed some mood ratings but did not establish protection from alcohol effects or fitness to drive.
Can a Harder Inhibition Task Show a Smaller Alcohol Effect?
A 20-man study found an alcohol-related rise in inhibition errors in easier task conditions but no significant increment in the hardest condition. Baseline difficulty and response preparation explain why this is not evidence that complex driving is safer.
Can Ethanol From a Denture Liner Raise a Breath Alcohol Reading?
One ethanol-containing liner produced measurable breath readings in a ten-person experiment without an alcoholic-drink challenge. The study did not measure blood alcohol or establish a universal one-hour clearance rule.
Alcohol and the Cocktail Party Effect: What an 81-Person Listening Study Found
Alcohol did not significantly change detection of a person’s name in ignored speech. Evidence for other listening outcomes was less decisive, and the task did not establish intact driving attention.
Can a Zero Breath Alcohol Reading Exclude Next-Morning Driving Deficits?
A 52-driver naturalistic study found poorer simulated driving after drinking, including among 26 people with zero breath readings. Residual-alcohol groups differed on some outcomes, and sleep and blood alcohol were not directly established.
What Does a Null Alcohol–Alprazolam Interaction Mean for an Impairment Opinion?
A crossover trial found cognitive impairment after 1 mg alprazolam, alone or with alcohol, but no clear additive effect at the achieved alcohol exposure. Timing and reporting limits prevent a conclusion of safety.
Did Alcohol Increase Laboratory Risk-Taking and the Urge to Drink?
A randomized 142-student experiment found more balloon-task risk-taking and a greater rise in alcohol urge after drinking. Statistical mediation did not establish the causal sequence or predict a driver’s decisions.
Does CPAP Make Alcohol Clear Faster? Ethanol and Acetaldehyde Had Different Results
A 53-man crossover study found improved sleep measures and a larger overnight acetaldehyde decline with CPAP. The additional ethanol decline was not statistically significant, and driving recovery was not tested.
Does Professional Motor Skill Protect Against Alcohol Effects? Nine Neurosurgical Residents
Nine neurosurgical residents completed repeated manual tasks before and after drinking. Faster completion sometimes accompanied poorer quality, but the small uncontrolled sequence did not quantify driving impairment or prove tolerance.
Does Alcohol Reduce Every Measure of Visual Contrast Sensitivity?
A 20-person crossover experiment found different alcohol effects for different visual patterns. Some thresholds improved, others worsened, and several did not change significantly; this was not a driving-performance test.
Can Hangover Severity Reveal a Driver’s Alcohol Elimination Rate?
An eight-person analysis linked faster breath-based elimination with milder hangovers at selected times. Measurements from separate years, estimated drinking exposure and exploratory statistics prevent individual BAC reconstruction from symptoms.
Can Alcohol Increase Resting Brain Blood Flow While Slowing Its Response to Visual Activity?
A 30-person study found higher resting cerebral flow velocity but slower responses to visual stimulation after alcohol. Average response, peak timing and electrical visual measures answered different questions.
Does Alcohol Affect Communication Between the Brain’s Motor Cortices Differently by Sex?
A 22-person crossover study found a sex-by-alcohol interaction in a motor-cortex stimulation measure. It did not test driving or establish a person’s degree of behavioral disinhibition.
Did Acute Alcohol Significantly Change Blood Clotting in Healthy Volunteers?
A 20-person ROTEM study found a small early fibrin-clot change before statistical correction, but the overall result did not survive correction for multiple comparisons. It measured neither crash causation nor bleeding outcomes.
How Did Alcohol Change Field Sobriety Findings in Heavy Cannabis Users?
In a small crossover study, adding alcohol to smoked THC changed some field-test findings, but overall scores were less decisive. Baseline findings, timing and the absence of an alcohol-only arm limit attribution.
Can BAC, EtG and PEth Distinguish One Drinking Episode From Repeated Use?
An 87-person forensic sample linked higher BAC with higher EtG and PEth, but overlapping results, unknown drinking times and transport conditions limit individual drinking-history conclusions.
Can Assisted Breathing Change Alcohol Elimination? A Five-Man Pilot Study
A laboratory pilot found faster ethanol clearance during controlled isocapnic hyperpnea. The intervention, breath-based kinetics and two-person blood comparisons do not support a general sobering method or a standard DUI back-calculation rate.
Can a Clinical Exam Establish a Low Alcohol Concentration After Trauma?
A small trauma study found clinical observations did not reliably track breath-based alcohol estimates. Incomplete testing and inconsistent reported counts prevent a precise diagnostic accuracy claim.
How Well Did a Personal Breathalyzer Agree With a Police-Grade Device?
A 337-person study found strong correlation between two breath devices, but individual agreement and threshold classification require separate analysis. Its table also exposes mislabeled diagnostic percentages.
Can a Bayesian BAC Reconstruction Overcome an Uncertain Drinking History?
A forensic case report used population pharmacokinetics and bootstrap predictions, but uncertain inputs and extreme parameter estimates limited what its probabilities could establish.
Can a Parking Collision Alone Prove Alcohol Impairment?
A real-car experiment linked increasing blood alcohol with more parking collisions, but single collisions occurred while sober too. The findings do not validate a diagnostic rule for an individual driver.
