Presentation Transcript

  1. Diseases and Dependencies • Alzheimer Disease • Parkinsons Disease • Drugs • Alcohol

  2. Alzheimer Disease • Plaque • Nerve tangles

  3. Parkinson’s Disease • Decrease CNS dopamine secretion

  4. General drug actions

  5. Cocaine: stimulant Cocaine Coca Plant Increases dopamine Cocaine

  6. Cocaine • What are the short-term effects of Cocaine Use? • Increased energy • Decreased appetite • Mental alertness • Increased heart rate and blood pressure • Constricted blood vessels • Increased temperature • Dilated pupils

  7. Cocaine What are the long-term effects of Cocaine Use? • Addiction • Irritability and mood disturbances • Restlessness • Paranoia • Auditory hallucinations • Numerous effects on • HEART • RESPIRATION

  8. Examples of some drug opiates • Morphine • Heroine • Codeine

  9. Heroine Heroin is processed from morphine, a naturally occurring substance extracted from the seed pod of the Asian poppy plant. Poppy Plant Street names associated with heroin include "smack," "H," "skag," and "junk."

  10. Heroine Soon after injection (or inhalation), heroin crosses the blood-brain barrier. In the brain, heroin is converted to morphine and binds rapidly to opioid receptors.

  11. Methampethamines • street names:Chalk, Crank, Croak, Crypto, Crystal, Fire, Glass, Meth, Tweek , White Cross. • Methamphetamine can be taken orally, injected, snorted, or smoked.

  12. Methampethamines • It rapidly enters the brain and causes a cascading release of norepinephrine and dopamine (and to a lesser extent, serotonin) resulting in euphoria and the availability of undirected energy.

  13. LSD (lysergic acid diethylamide) • LSD: has a chemical structure that is very similar to the neurotransmitter called serotonin. Originally from fungus of rye Plants: 1938

  14. Cannabis Tetrahydrocannabinol (THC) stimulates receptors of pain and appetite

  15. Ectasy Methylenedioxymethamphetamine (MDMA)Street Names: X, XTC, E, Adam, Lovers Speed, Eve, Beans, Clarity, Essence, etc. Potential to damage the serotonin receptor sites as well as the serotonin neurons of the brain

  16. Alcohol Stimulates inhibitory receptors at high doses Can be excitatory at low doses

  17. Stimulant • Binds to acetylcholine receptors Acetylcholine receptor
