Does loss of consciousness mean worse concussion?

How long do you lose consciousness with a concussion?

Do you always lose consciousness with concussion?

As the Brain Injury of Association of America explains, even medically trained specialists do not always recognize brain injury symptoms.
What causes loss of consciousness with concussion?
Traumatic brain injuries can cause bruising, damage to the blood vessels, and injury to the nerves. The result is your brain doesn’t function as it should. If you’ve had a concussion, vision may be disturbed, you may lose equilibrium, or you may fall unconscious. In short, the brain is confused.
How long does loss of consciousness last?
Loss of consciousness that lasts for more than a minute or two can be serious, however. Often it is a sign of a serious medical problem, such as seizure, serious blow to the head, concussion, heart attack, diabetic coma, epilepsy, or another condition.
What part of the brain is affected when you lose consciousness?
There are three causes of fainting. Fainting is the sudden and temporary loss of consciousness, and consciousness arises from neural activity in the cerebral cortex. Anything that disrupts neural activity in the cerebral cortex can cause loss of consciousness.
How do you know if you have lost consciousness?

Can a concussion make you blackout?
The most common type of head injury is concussion. Concussion may or may not include loss of consciousness (blackout). The loss of consciousness is often brief and is normally followed by a rapid and complete recovery. Always seek medical attention for a head injury.
Can you faint without losing consciousness?
If you have symptoms of dizziness or lightheadedness without loss of consciousness, this is often called presyncope (or near-syncope); however, dizziness and lightheadedness are nonspecific symptoms that can also be caused by conditions that are unrelated to syncope (such as inner ear disorders).
