What Do All These Drugs Have in Common?

DOPAMINE

A neuropeptide that functions as a chemical messenger in two important brain areas

Reward/ Salience system

Ventral Tegmental Area

Nucleus Accumbens Other AreasCoordinated movement systemBasal Ganglia

Slide5

Dopaminergic Reward System

Slide6

Slide7

Reward System Is Vital to Survival

Stimulated when individual engages in behavior that promotes survival

Fighting

Fleeing

Feeding

Sexual activity

Also stimulated by dopaminergic drugs that mimic these natural brain responses

Very primitive part of brain

Slide11

Why Is Addiction Stigmatized?

Throughout history, we have tried to explain addiction using a moral model

Persons with addiction appear to be

choosing

to use drugs

Persons with addiction appear to be self-centered, morally bankrupt, evil, crazy or stupid

One person in active addiction can ruin your whole day

Slide12

Slide13

In Vulnerable Individual, Drug Use Leads to Brain Modification

Changes in receptor sensitivity

Changes in brain stores of neurotransmitters

Changes in balance of neurotransmitters

Changes in memory functions and affect

Modifications in cortical structures and function

Behavior and thinking changes in response to these brain changes

Slide14

“Your Brain on Drugs”

As drug enters the brain, dopamine “lights up” the affected areas

Over time, effect wears off as brain breaks down drug

After drug is gone, brain is

less

stimulated than before use

Slide15

Keys to Working Effectively with Addicted Persons

Remember that, in active addiction, the primitive brain is dominating

Just because a person didn’t use drugs today, it doesn’t mean that his/her brain is not chemically affected (it can take many months

to years for

this to change)

The person in active addiction or early recovery is “not playing with a full deck!”
