Narrative review of preclinical animal research without human clinical data.

What was done
This narrative review synthesized recent preclinical studies modeling compulsive alcohol and cocaine intake in rodents. It evaluated behavioral paradigms of aversion-resistant intake—specifically pairing drug seeking or consumption with bitter tastants (quinine) or electric footshocks—and examined technical, conceptual, and neurobiological findings.
What was found
The abstract reports no quantitative values or comparative statistics. It summarizes qualitative findings demonstrating that pairing alcohol seeking or intake with negative stimuli (quinine or footshock) successfully models aversion resistance and has identified key neuroadaptations across the amygdala, cortex, and striatum.
Why it matters
Compulsive, punishment-resistant drinking is a defining feature of human alcohol use disorders that complicates clinical treatment. Preclinical models that capture this behavior help map the neural circuits driving addiction and guide future therapeutic targets.
Limits
As a narrative review of animal research, it provides no systematic search protocol or quantitative pooled data. Findings from rodent aversion paradigms cannot fully replicate the complex psychosocial, legal, and economic factors driving human compulsive alcohol use.
