Drug Abuse and Addiction: Pharmacological Phenomena

Drug Abuse and Addiction: Pharmacological Phenomena

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Background:

Craving is a key symptom in substance use disorders and addictive behaviors.
Neural mechanisms underlying craving are extensively studied.
Connectome-based predictive modeling (CBPM) is emerging for predicting craving.

Purpose of the Study:

To compare, contrast, and consolidate findings from four studies using CBPM to predict craving.
To develop a theoretical model of functional connectivity-craving relationships.
To analyze methodological and conceptual variations across studies.

Main Methods:

Review and synthesis of four existing studies employing connectome-based predictive modeling.
Comparative analysis of study methodologies, samples, and craving conceptualizations.
Development of a theoretical model integrating findings on functional connectivity and craving.

Main Results:

Four studies utilized CBPM to predict craving related to substance use, addictive behaviors, and food.
Significant heterogeneity was observed in methods, samples, and definitions of craving across studies.
A theoretical model was derived to explain functional connectivity-craving relationships.

Conclusions:

Connectome-based predictive modeling shows promise in understanding craving mechanisms.
Standardization of methods and conceptual clarity are needed for future research.
The derived model offers a framework for future investigations into brain connectivity and craving.
