  1. The Brain Cassie Aramil

  2. Nutrition and the Brain

  3. What the brain needs • Glucose • Vitamins • Minerals • Essential chemicals

  4. A good healthy diet • Proteins • Fatty acids • Vitamins • Minerals

  5. Neurotransmitters in diet • Aspartic: found in peanuts, potatoes, eggs and grains. • Choline: found in eggs, liver and soybeans. • Glutamic Acid: found in flour and potatoes. • Phenylalanine: found in beets, soybeans, almonds, eggs, meat and grains. • Tryptophan: found in eggs, meat, skim milk, bananas, yogurt, milk, and cheese. • Tyrosine: found in milk, meat, fish and legumes.

  6. What happens when the brain doesn’t get certain nutrients • Change in mood • Change in behavior • Abnormal brain functions

  7. Bipolar disorder Bipolar disorder is a condition where you experience extreme changes in mood, behavior and energy levels

  8. Causes of bipolar disorder • Altered levels of neurotransmitters like serotonin and norepinephrine • Altered brain structure • Genetics

  9. Symptoms of bipolar disorder Mania • High self-esteem • Reduced need for sleep • Excessive talkativeness • Racing thoughts • Desire to spend excess amounts of money • Pursuit of risky behaviors or activities Depression • Loss of interest in activities previously enjoyed • Changes in appetite resulting in weight gain or loss • Changes in sleep patterns • Agitation • Energy loss • Trouble concentrating or thinking • Repeated thoughts of suicide or death

  10. Affects of bipolar disorder on the brain • Glial cells decrease in number and density in prefrontal cortex • Neurons decrease in the hippocampus • Levels of some neuropeptides in the hypothalamus increase • Size of the cerebellum decreases • Reduced activity in the prefrontal cortex during the depressive stage

  11. Treatments Medications • Lithium • Anti-depressants Therapy Everybody responds differently to treatments, so most people use the “trial and error” method

  12. BarbituRATES These drugs are often called “Sleeping Pills” and they act to depress the central nervous system.

  13. TYPES OF BARBITURATES • Pentobarbital (Nembutal) • Secobarbital (Seconal) • Amobarbital (Amytal) • Phenobarbital (Luminal)

  14. Behavioral affects of barbiturates In low doses They reduce… • Respiration • Anxiety • Heart rate • Rapid eye movement (REM) sleep In high doses • Anesthesia • Coma • Death

  15. How barbiturates affect the brain • Have easy access into the brain! • Bind to sodium channels • Prevent the flow of sodium ions • Increase flow of chlorine ions • Can become addictive
