- 1. Be Smart, Helmet Your Brain MARINA Y. USACHEVA, M.D. UNIVERSITY OF IOWA STUDENT HEALTH AND WELLNESS
- 2. Skiing
- 3. Snowboarding
- 4. Biking
- 5. Motorcycling
- 9. What is missing here?
- 11. Why do we need helmets?
- 14. Injuries do happen Damage to the brain can affect EVERYTHING you do, from thinking to moving It can lead to coma and death
- 15. The Brain … What is it and what does it do?
- 19. What does the brain do? When you're thinking hard, you're using your brain You need the brain To solve math problems To figure out a video game Play instruments Draw a picture Read a book
- 20. Cerebrum (Brain) Hemispheres Left hemisphere Reasoning skills Speaking Writing Number skills Movement of the right side of the body Right hemisphere Creative skills Imagination The left side of the body Insight Musical ability and interpretation Awareness of three dimensions
- 21. The Brain Lobes Frontal lobe Main movement of extremities, trunk and eyes Memory Judgment Behavior control Parietal Lobe Sense of space Sensation Other movements
- 22. The Brain Lobes Temporal Lobe Language Plays an important role in emotions Assists with memory Cerebellum Coordination Timing Occipital lobe Vision
- 23. The Brain Brain stem Breathing Blood pressure Arousal Did you know that Human brain weighs ~ 3 pounds ( 1.4 kg)
- 24. Brain Anatomy
- 26. Neurons = Nerve Cells Neurons have Cell body Dendrites Axons Neurons carry messages
- 27. Did you know that… Human brain is made up of over 10 billion neurons The neurons are surrounded by the glia (from the Greek “glue”) Some neurons are over a meter long
- 29. The brain has many different parts that work together Cerebrum Cerebellum Brain stem Hypothalamus Hippocampus Pituitary gland
- 30. Brain development and function When you learn things, the messages travel from one neuron to another, over and over Eventually, the brain starts to create connections (pathways) between the neurons, so things become easier and you can do them better and better Informative routs. Sensory and motor signals
- 31. Neurons When you were born, your brain came with all the neurons it will ever have, but many of them were not connected to each other
- 32. Head and Brain Anatomy Your brain sits inside a hard, bony skull
- 33. Head and Brain Anatomy Layers of membranes n Dura mater n Pia mater n Arachnoid Fluid around the brain provide additional padding
- 34. Head and brain Anatomy Layers of membranes Dura mater Pia mater Arachnoid Fluid around the brain provides additional padding
- 35. Brain injuries
- 36. Skull fracture Skull fracture= Crack If the sharp edges of a fractured skull bone press into the brain, they can damage the delicate tissues and lead to bleeding in the brain One sign of a skull fracture is clear fluid or blood draining from the nose or ears
- 38. Traumatic brain injury (TBI) Mild A concussion Quick recovery (usually) Moderate
- 39. Severe TBI Can do enough damage to knock you unconscious for a longer period of time A hard blow to the head can shake the brain inside the skull, resulting in bruising, broken blood vessels, or nerve damage It can even lead to a coma or death
- 40. Healing after concussion Rest! Rest! Rest! Just like you need to rest your ankle after a sprain, you need to rest your brain after a concussion. Get plenty of sleep to give your brain time to heal. Stay off the playing field until your doctor gives you the OK. Getting a second concussion before the first one has healed can slow your recovery and increase the risk for permanent brain damage
- 41. Diagnosing TBIs “Invisible injury” Coaches, athletic trainers or parents can do initial assessment However, the people most qualified to diagnose a brain injury are emergency room doctors, pediatricians, family physicians, neurologists and neuropsychologist
- 44. How Common Are Brain Injuries? Every year, 1.7 million people have an accident that leads to a traumatic brain injury Most injuries (~ 75% ) are mild, including concussions But more serious brain injuries send 275,000 people to the hospital and cause 52,000 deaths every year
- 45. Helmets and Why Do We Need Them? A type of protective headgear Helmets are made to protect and cushion your brain from the crash Helmets prevent traumatic brain injury (TBI), disability, and death
- 46. Do Ski Helmets Help Prevent Head Injury? The Brave Ski Mom (October 15, 2012, CO) Yes Research conducted over the past 20 years shows that children under age 15 are more likely to suffer a head injury while skiing or snowboarding than any other age group. For kids in this group, a helmet can prevent or reduce the severity of the injury by 53%.
- 48. Yes No
- 49. Barriers to helmet use Peer pressure Cost Inconvenience Poor fit and discomfort Damage to personal appearance Lack of knowledge about consequences of TBI
- 50. Remember Any helmet is better than no helmet at all Brain injuries do not discriminate and might happen to Anyone Anywhere Anytime
- 51. SAFETY
- 54. Be Smart, Helmet Your Brain
