Addiction is a serious public health problem that causes
morbidity and mortality and economic burden. Recognizing
that addiction results from the choices made by those with that
disorder, the eld of addiction science, beginning in the 21st
century has increasingly focused its attention on decisionmaking
processes. A hallmark of addiction is the fact that the individual
suffering fromit continues tousedespitenegativeconsequences.
Progress in identifying the neurobehavioral decision processes
underlying disadvantageous decisionmaking evident in addiction
could facilitate the transition from a symptom-focused approach
to a mechanism-focused approach, and this may further the
development of treatments for these conditions. Decision-
making impairments can be both the cause and consequence of
addiction. Some of the traits linked to substance use vulnerability,
such as reward-sensitivity and impulsivity, contribute to poorer
performance in decision-making tasks. Similarly, the deleterious
effects of chronic substance use on frontostriatal and limbic
systems have been shown to produce or exacerbate impairments
in cognitive control processes that contribute to decision
making, such as working memory. This presentation will focus
on neurobehavioral theories of impaired decision-making in
addiction; impairments in three stages of decision-making in
addiction, namely, preference formation, choice implementation,
and feedback processing; and implications of impaired decision-
making in addiction.
