What is the difference of DUI and concussion and their consequences?

Concussion is when there is a shaking or striking causes a person's brain to incur a trauma. The result can be that a person experiences nausea, vomiting, dizziness, unconsciousness, eye problems, or more. The concussion can be anywhere from mild to extreme. DUI is operating a motor vehicle while one's normal faculties are impaired due to drugs or alcohol. Of course, it is possible for someone to do both. A person could be drunk, get punched or in an accident, and suffer a concussion. The question for your case is what evidence does the state have that you were under the influence. If there is a blood test from the hospital that shows a large amount of alcohol in your system, or perhaps certain drugs, then it would be for a jury to decide whether you were guilty of DUI. The other question is how do you prove that you had a concussion. You might have to testify and that is always a dangerous path for a defendant to take.
