Dr. Barry Sears discusses inflammation and its direct relationship to concussions. His labs have developed a test for the detection of inflammation and related symptoms of concussion

Underlying Cause of Chronic Illness

• Increased Inflammation

What is Inflammation?

• Ancient Greeks– Internal Fire

• Ancient Romans– Heat– Pain– Swelling– Redness

What is Inflammation?

• Complex orchestration of pro-inflammatory and anti-inflammatory events

• Usually associated with pain• Mediated by eicosanoids• Treated by drugs that alter eicosanoids

– Aspirin– NSAID’s– COX-2 inhibitors– Steroids

Events That Turn On Inflammatory Responses

• Microbial invasion

• Injuries

• Diet

Two Types of Inflammation

• Screaming Pain– Organ or joint damage

• Silent Pain– Cellular inflammation

Measuring Cellular Inflammation

• High sensitivity C-reactive protein– Non-specific– Highly variable due to infection

• AA/EPA Ratio– Most precise marker of eicosanoid

precursors at cellular level– Highly reliable

Typical AA/EPA Ratios

Diseases Associated With Cellular Inflammation• Obesity• Type 2 Diabetes• Heart Disease• Cancer• Alzheimer’s• ADHD• Asthma• Allergies• Inflammatory conditions (“itis”)

Typical Chronic Conditions In Retired NFL Players

• Obesity• Diabetes• Heart Disease• Arthritic Pain• Depression• ADHD• Dementia

My Early Days With The NFL

• Marv Marinovitch

• Garrett Giemont

• Jon Kolb

Improvement of Performance Of NFL Players

• LA Rams– Doug Smith– Lucious Smith

• Pittsburgh Steelers– Steve Courson

Current NFL Teams We Work With

• Green Bay Packers• New York Jets• San Diego Chargers• Oakland Raiders

Traumatic Brain Injury

• Leading cause of death and lifelong disability among children and young adults in the United States

• 1.5 million Americans survive a traumatic brain injury, among whom approximately 230,000 are hospitalized

• 50,000 Americans die each year following traumatic brain injury

Protocol

• EPA/DHA concentrate (2:1)

• 15 grams of EPA and DHA per day

• Measure AA/EPA ratio in the isolated plasma phospholipids weekly to ensure AA/EPA ratio >1.5

AA/EPA Ratio Can Change Rapidly In Brain Trauma Patients

• Pre-Treatment (11-23-10)– AA/EPA ratio = 41

• Post-Treatment (1-20-11)– AA/EPA ratio =3

Other Neurological Conditions Treated By

High-Dose Fish Oil

Bipolar Depression Can Be Treated with High-Dose Fish Oil

• 9.6 grams of n-3 per day

• 500% greater remission in 3 months

Summary

• Cellular inflammation is the underlying cause of neurological disease

• It can be reversed by high-dose fish oil• Test, don’t guess about how much fish

oil you need• No one is going to help you rebuild

your brain except yourself
