What you need to know

• Focuses on neurochemical imbalances, particularly with the neurotransmitter dopamine.
• The mesolimbic reward pathway is believed to be overactive or hypersensitive.
• The impulsive behaviour provides a dopamine rush, leading to reinforcement and craving.
• Potential dysfunction in the prefrontal cortex impairs the ability to inhibit impulsive urges.
• Genetic predispositions may make some individuals more vulnerable to developing ICDs.
