1. What is Addiction? Addictive Substances

2. ADDICTION- From Here to There I’m having fun with my friends I’ll try it just once What’s the big deal I’m just experimenting I had a tough week, so need to relax I can handle it I steal from my family and friends I lie My life has no direction I hurt myself I hurt others This affects every relationship I can’t seem to stop

3. Regions of the Brain Each region of the brain is responsible for activities vital to living Brain stem – heart rate, breathing, eating, sleeping (basics to sustain life) Cerebellum – movements, balance, and posture Cerebral Hemisphere – the “thinking center”/process language, math, strategies

4. Cerebral Cortex Divided into the right and left hemispheres and is 2/3 the mass of the brain Most highly developed part of the brain Responsible for thinking, perceiving, and producing and understanding language Each area has a specific function

6. (The Prefrontal cerebral cortex area is the) “CONTROL CENTER” for LOGIC/JUDGMENT = A BIG PROBLEM FOR TEENS because that part of your brain MATURES LATER - early twenties KEY POINT > Why is that SO important?

7. ENTER >Drugs They are SO powerful because they act directly on this center and override the cerebral cortex. They eliminate the most human part of our brain from its role in “controlling” our behavior.

8. Hippocampus – memory Thalamus – sensory perception and regulation of motor functions Hypothalamus – regulates appetite, body temperature, pituitary and adrenal gland function. Limbic System – (known as the “Reward Center” is located deep within the cerebral cortex. Made up of complex structures such as the following:

9. MATURES EARLIER Major Role in emotional responses Key points for teens IMPACT FOR TEENS - make impulsive, emotional decisions rather than, carefully considered, logical choices

10. Nerve Cells and Neurotransmission How we communicate messages! Brain is made up of billions of nerve cells called neurons –Cell body – directs all activities of the neuron –Dendrites – fibers that receive messages from other neurons and relay them to the cell body –Axon – long single fiber that transmits messages from cell body to dendrites of other neurons = Neurotransmission Axon Terminals – the ends of the axon

11. Neurotransmission: Synapse Communication between brain nerve cells does NOT occur through direct contact. As the message comes down the axon, there is a release of chemical substances (neurotransmitters) into the NON-CONTACT space between the axon terminals and dendrites of another neuron SYNAPSESYNAPSE

12. Neurotransmitters: Key and Lock There are specific receptors on the ends of dendrites (Locks) that have a very specific matching neurotransmitters (keys) that can bind to it. When this happens, the message carried by the neurotransmitter is received and processed by the dendrite of the receiving neuron This message is then relayed to the cell body and then to the axon, and so forth.

14. 3 Types of Neurotransmitters Serotonin Dopamine Epinephrine

15. Drugs can change how messages are sent in these 3 ways They can act like neurotransmitters (faker) They can change the amount of neurotransmitters in synapses (thief) They can block neurotransmitters Key point > drugs affect the way we perceive and respond to the world around us. http://foundation.methproject.or g/Our-Work/brain-and- behavior.php

16. Examples of drugs doing this … All drugs that change the way the brain works affect neurotransmission. Ex: depression =low levels of serotonin > Medication (prescribed drug) = tells the body to increase serotonin Other examples: 1.LSD, Ecstasy (fakers) act like the natural neurotransmitter the body makes (similar size and shape, so they fit the key/lock and send the message) 2.PCP (a “road block”) blocks receptors and prevents messages from getting through PCP

17. and 3. Methamphetamine, Heroin flip the switch faster!! (thief) causing large amounts of neurotransmitters to be released at once into the synapse (like a pump). This causes an OVER-STIMULATION OF THE BRAIN SYNAPSE with NO RECOVERY TIME. (BRAIN DISTRESS)

18. 4. Cocaine, marijuana, nicotine interfere with the transporters responsible for sending the neurotransmitters back into the neurons that released them – therefore, they stay in the synapse (unnatural flooding of neurotransmitters) (creates depression later in life from low natural levels) = Brain can’t function normally

20. Drugs of Abuse If taken over long periods of time, drugs can change feelings and behavior in the user. All drugs that are addicting can activate the brain’s “reward/pleasure center” causing ‘feel good” messages to travel from neuron to neuron

21. The Brain’s Reward System A.K.A. The Limbic System Used to reinforce healthy behaviors –Examples: eating when hungry, drinking when thirsty To encourage the body to reinforce healthy behaviors, the neurons release a neurotransmitter called Drugs that turn on the brain’s reward system trick the mind into believing that the drug is good for the body. All drugs of abuse affect the brain’s reward system by the system with dopamine. DOPAMINE FLOODING

22. http://video.about.com/alcoholism/Drug-Addiction.htm

23. To Review: What Happens if Someone Keeps Using Drugs??? With drug use, the brain starts changing immediately as a result of the unnatural flooding of neurotransmitters. The drug changes the way the brain actually works. How? 1 by reducing the number of dopamine receptors 2 stopping the production of dopamine all- together 3 actually killing some of the neurons

24. Permanent brain changes The result = low dopamine levels in the drug abuser’s brain when not on the drug. Without drugs, the abuser feels flat, lifeless, depressed, and unhappy. Brain says “ I NEED” Drugs are needed just to bring dopamine levels back up to normal.

25. Permanent brain changes The abuser is now: DEPENDENT = the user needs the drug just to function normally AND He/she becomes a compulsive user. ADDICTED = The user can no longer control his or her drug use because the brain has changed.

26. I AM AN ADDICT I steal from my family and friends I lie My life has no direction I hurt myself I hurt others This affects every relationship I can’t seem to stop

27. ADDICTION IS… A condition in which a person no longer controls his/her behavior. He/she desires to continue despite the negative consequences

28. ADDICTION IS… A chronic, yet treatable brain Dis-Ease.
