About 750, 000 people have a stroke in the US each year and about 20% die making stroke the third leading cause of death. It is also a leading cause of disability. Can you recognize symptoms of a stroke? Do you know what to do?

Stroke is called Brain Attack because prompt treatment, as given for heart attacks, could save many lives and significantly reduce disabilities from stroke. Lawrence Livermore Laboratory's Medical Technology Program has developed several systems to detect and treat stroke and other diseases of the circulatory system in the head. In this presentation you will learn about blood flow to the brain, types of strokes, aneuysms (bulging artery) and hematomas (blood or fluid pocket in the skull). You will also learn about current treatment and some new treatment possibilities, several of which are LLNL technologies. One LLNL technology for unclogging blocked arteries in the head, called photoacoustic thrombolysis, is in clinical trails. Most importantly, you will learn the symptoms of stroke and why you should treat stroke as a Brain Attack: a time critical emergency.

Today you will learn

  • What is a stroke
  • To identify two types of stroke
  • What are stroke signs
  • What to do if someone is having a stroke
  • New Stroke treatments and the role LLNL is playing

Dr. John Marion

John Marion attended UC Berkeley where he received his Ph.D. in Materials Science in 1984. He then joined the Lab and ran programs in materials characterization, laser crystal growth and hypervelocity missiles. In 1995-96 he was the liaison for the Laser program in Paris France. John is now the Special Studies Leader for the Medical Technology Program at Lawrence Livermore and Professor of Clinical Pathology, Volunteer, University of California, Davis. He is responsible for the development of new initiatives in biomedical technology. John is also Director of the Industry Partners Consortium, a collaborative effort between UC Davis Health System and Lawrence Livermore Laboratory commercializing biomedical technology. Dr. Marion has written over 50 publications in the scientific literature. He has been active in laser materials development, fracture of brittle materials and ultra short pulse lasers for biomedical applications.

Kirk Brown

Biology Teacher
Tracy High School

Kirk Brown teaches International Baccalaureate Biology at Tracy High School in Tracy, California. He has 15 years of experience as a teacher and has served as a Mentor Teacher for Tracy Unified School District. He founded the Agricultural/Scientific Academy at Tracy High School, and has worked on science education projects with the California Department of Education, Lawrence Livermore National Laboratory (LLNL), San Joaquin County Office of Education, Access Excellence (Genentech), and the Exploratorium and has an on-going partnership with Biorad Laboratories. Kirk is also an adjunct faculty member of San Joaquin Delta College. He has his Bachelor of Arts Degree in Biological Science with a concentration in Entomology from California State University Stanislaus and his Master of Arts Degree in Education from the University of the Pacific. While working with LLNL, Kirk worked with other teachers to co-author the Biotechnology Education Program, Laser Science & Optics for the Classroom, and Past Director of the Student Research Academy, and Teacher Research Academy. These programs focus on teacher or student development and training, with a strong focus on integrated instruction. More recently, he has been involved in the development and implementation of a summer research program for high school students at LLNL. Currently, Kirk is the Director of the Biotechnology Pillar at the Edward Teller Education Center. Kirk has worked at the District level writing new K-12 goals, desired learning_s and benchmarks that integrate the National and State standards. Kirk has been named teacher of the year and has won numerous awards including the Milken National Educator Award and most recently, California_s Outstanding Biology Teacher for 2003 by the National Association of Biology Teachers.
