Presentation Transcript

  1. Addiction as a Disease • Arlin J.Silberman D.O.,FAOAAM • Certified in Addiction Medicine • Certified in Addiction Psychiatry • Fellow of the American Osteopathic Academy of Addiction Medicine

  2. Abuse vs Dependence • There is a difference between intentional drug abuse and pathological drug dependence. • The latter is what is referred to as addiction.

  3. Chemical Abuse • Maladaptive pattern of drug use leading to impairment or distress,presenting as one or more of the following over a 12 month period-failure to fulfill obligations,use that is physically hazardous,drug related legal problems,and continued use despite social/interpersonal problems.

  4. Chemical Dependence • 3 or more of the following:tolerance,withdrawal,drug used more than intended,inability to control use,effort to obtain drug,important activities replaced by drug use,use despite negative consequences.

  5. Present Understandings • Drug abuse causes short-term and long-term changes in brain function. • Medial forebrain bundle(mesolimbic dopamine system)

  6. History • References made in the civilizations of ancient Egypt and Greece,called ‘drink madness’. • In colonial America, Anthony Benezet noted drunkenness to self accelerate. • In 1784 Dr.Benjamin Rush wrote a pamphlet describing an ‘odious disease’and a ‘disease induced by a vice.’

  7. History cont. • Rev.Lyman Beecher’s sermons in 1825 describes ‘intemperance is a disease as well as a crime.’ • Dr.Samuel Woodward recommended special asylums for the treatment of inebriates.(1830’s)

  8. First Treatment Facility • In 1864 the New York State Inebriate Asylum founded by Dr.Joseph Turner.

  9. Disease Concept • Dr.William Sweetser described intemperance causing a ‘morbid alteration’ in nearly all the major structures and functions of the human body.(1829)

  10. Concept of Alcoholism • Biological predisposition • Drug toxicity • Morbid craving • Tolerance • Disease progression • Loss of volitional control over quantity

  11. Opiate Addiction • In the 1870’s dope fiends where caricaturized as Chinese immigrants when the majority were white middle-aged women using patent medicines laced with opium.

  12. Criminalization • Dr.CW.Earle led the first anti-drug campaign.”It is becoming altogether too customary in these days to speak of vice as disease” • In the 1880’s the term ‘drug vice’ used.

  13. Disease Concept • American Association for the Cure of Inebriety formed in 1870. • Founding principles-disease concept,curable,constitutional susceptibility which maybe inherited or acquired.

  14. Moral Treatment • Franklin Reformatory for Inebriates in Phila. recognized ‘drunkenness as a habit,sin,and crime.’(1874)

  15. Alternative views of alcohol and drug use • Source of the problem was in the person in terms of vice and sin. • Source of the problem was the product. • Aggressive promotion of the product.

  16. Disease Concept Abates • By the end of the 1800’s the disease concept faded away.

  17. Disease Concept Returns • E.M.Jellinek presents disease model in 1960. • American Psychiatric Assoc. uses the term disease to describe alcoholism in 1965. • American Medical Assoc. follows in 1966.

  18. Present Understandings • Drug abuse causes both short-term and long –term changes in brain function. • This makes it nearly impossible for users to stop on their own. • The biology of the brain changes may never return to preuse state.

  19. Our Understandings • ‘Dependence’brain areas are parts of the brain that govern unconscious thought. • Medial forebrain bundle,also known as mesolimbic dopamine system. • Neurotransmitters involved in dependence.

  20. Our understandings • Functional dysregulation-they aren’t working right. • One or more neurotransmitter chemicals involved.

  21. Neurotransmitters • Dopamine(affected by cocaine, amphetamines or alcohol). • Serotonin(alcohol or LSD) • Endorphins(alcohol or opiods)

  22. Neurotransmitters • GABA(alcohol or benzodiazepines) • Glutamate(alcohol) • Acetylcholine(alcohol or nicotine)

  23. Genetic Factors • Abnormal genes lead to abnormal proteins. • This results in abnormal transmitter-synthesizing enzymes,abnormal transmitter breakdown enzymes,or abnormal receptors.

  24. Genetic Factors • The above factors lead to neurotransmitter dysregulation. • This is why scientists believe that dependence is a chronic medical brain disease.

  25. Needs Long Term Treatment • As chronic relapsing disease like heart disease,diabetes and schizophrenia,disease management,not one shot treatment,is the most promising approach. Alan Leshner PhD.,Director NIDA.(1997)

  26. Treatment Modalities Behavioral approaches change brain chemistry. Medications to treat withdrawal and cravings.

  27. Medications Approved for Alcohol Treatment • Antabuse(disulfiram) • Naltrexone • Acamprosate

  28. Critics of the Disease Model • Stanton Peele-disease concept has spread to include eating,child abuse,gambling,shopping,premenstrual tension,compulsive love affairs,and almost every form of self destructive behavior.

  29. Critics • Herbert Fingarette states alcohol industry itself contributes to the public perception of alcoholism as a disease.(Heavy Drinking:The Myth of Alcoholism as a Disease.1988 Univ.of Berkeley Press)
