Tampa Brain Injury Lawyer Matt Powell explains the Physics of how a brain injury and whiplash happens.

0:00 Introduction How Car Accidents Can Cause Whiplash
0:01 How Car Accidents Can Cause Brain Injuries
0:10 Isaac Newton Laws of Motion
0:16 First law of motion says an object at rest will remain at rest until acted upon by an outside force
0:25 And an object will continue in motion unless acted upon by another force
0:30 This is the law of inertia
0:44 All objects resist change in their state of motion
0:47 Second law of motion
1:02 How the laws of physics apply to a car collision
1:14 Before impact the occupant of the car is not moving
1:22 What happens when the car is hit
1:30 Most common misunderstanding
1:52 This graph explains the Gforces over time and how the human body is affected
2:30 How the human body moves in a crash
2:46 The torso moves first while the head remains still
3:06 This forces your head to have to accelerate to catch up to the car and your torso
3:17 Your neck has to points of stress and injury
3:22 First injury to the cervical spine is C56
3:30 Second injury is to your cervical spine at C12
3:48 How does a brain injury happen under the laws of physics
3:55 Brain injury on the cellular level
4:00 What is the difference between gray and white brain matter
4:13 Our brains are floating in cerebral spinal fluid
4:25 The density difference between gray and white brain matter cause the injuries
4:30 How many axons connect the gray and white matter in our brain
4:50 How the brain moves in a trauma
5;15 Different brain mass and floating in liquid cause shearing and tearing of the axons
5:33 What is diffuse axonal shearing
5:50 The laws of physics applied to your brain explains the cause of the injury
6:58 Head positioning can affect your brain injury
7:13 Do you have a loss of consciousness when you have a brain injury
7:20 Common symptoms of a mild traumatic brain injury
7:32 Why are many brain injuries undiagnosed
7:59 Why is the injured person the last to realize they have a brain injury
8:20 Will xray, CT or MRI show a brain injury
8:42 What tests show a brain injury
8:50 Does a DTI MRI show brain injury
8:58 Does a SWI MRI show brain injury
9:06 Does a CT pet scan show brain injury
9:20 What does a CT SPECT scan show about a brain injury
9:40 Will an MEG prove a brain injury
9:52 What other tests will show a brain injury
10:00 What do neuropsychological tests show about brain injury and brain function
10:30 If you have more questions call Matt Powell

A traumatic brain injury is caused by a bump, blow or jolt to the head.
This trauma or head injury disrupts the brain's normal ability to function.
Not all blows or jolts to the head result in a traumatic brain injury.
The severity of a brain injury can range from "mild," like, a brief change in mental status to "severe," an extended period of unconsciousness or amnesia after the injury.
Most traumatic brain injuries are concussions.

What is a Concussion?
A concussion is a type of traumatic brain injury, caused by a bump, blow, or jolt to the head that can change the way your brain normally works.
Concussions can occur from a motor vehicle accident, a fall or a blow to the body that causes the head and brain to move quickly back and forth, even though the head itself has no trauma.

Mild traumatic brain injuries are a result of microscopic damage throughout the brain that in turn initiates a cascade of biochemical events that leads to the subsequent formation of Alzheimer's disease.

Motor VehicleTraffic Crashes are the second leading cause of brain injuries 17.3 percent and resulted in the largest percentage of brain injury related deaths 31.8 percent.

Closed Head Mild Traumatic Brain Injuries:
A closed head injury is when the trauma does not fracture the skull, but the brain is damaged by a
sudden shaking or movement of the brain inside. If a person's head and brain has a sudden shake,
they will have what is commonly called an "Axonal Sheering Injury."
This injury happens when the axons connecting the white and grey brain matter are stretched and damaged.

75% of brain injuries are classified as mild brain injuries.
However, the definition is not very comforting if you are the one with the "mild brain injury."
Many emergency department doctors call a concussion a "mild" brain injury
because concussions are usually not lifethreatening.

Even though a concussion is not usually a life ending injury, it can have a life altering effect.
A brain injury can and does occur without a person being knocked unconscious.

Today, most doctors will agree that a brain injury does not require a loss of consciousness,
however, in the courtroom, most defense experts will say that without a loss of consciousness
there can be no brain injury.
The good news is that medical literature continues to expand and clarify that brain injury does happen without a loss of consciousness.
