•Polythetic approach to diagnosis means• Not all individuals who diagnose share overlapping symptoms• Many different combinations possible (2036!!)• Do these make a difference?

• Key concepts• Addictive substances have initial positively valenced effects• Over time, the nature of drug responses change
• Tolerance• Withdrawal• Incentive motivation
• These changes are durable• Multiple processes may be involved
• Incentive sensitization• Allostasis• Habit formation
Neurobiology of Addiction.George F. Koob, Ph.D.FOCUS 2011;9:55-65.
-Addictive drugs share the ability to produce long-lasting changes brain organization.
-The brain systems that are changed include those normally involved in the process of incentive motivation and reward.
- The critical neuroadaptations for addiction render these brain reward systems hypersensitive (“sensitized”) to drugs and drug-associated stimuli.
-The brain systems that are sensitized do not mediate the pleasurable or euphoric effects of drugs (drug “liking”), but instead they mediate a subcomponent of reward termed incentive salience or “wanting”

• Key Concepts• Shared pathology with other externalizing spectrum
disorders• Deficits in executive control/problems in impulsivity
• Multidimensional constructs• Excessive reward seeking/approach motivation• Associated with early onset problems• Associated with poor parenting and association with
