Synopsis

A traumatic brain injury (TBI) can be classified as either mild or severe and include a wide range of symptoms.

Overview

Are there specific symptoms that constitute a traumatic brain injury? Traumatic brain injuries or TBI aren't always detectable after an accident. Sometimes their symptoms won't appear until weeks or months later. A TBI can be classified as either mild or severe and include a wide range of symptoms.

Mild Traumatic Brain Injury

A TBI isn't always life-threatening or life-changing. If you experience a loss of consciousness for 30 minutes or less, your injury may be diagnosed as mild. Mild traumatic brain injuries are among the most prevalent and are also commonly called concussions. The symptoms and signs of a mild TBI are:

• Dizziness
• Headaches
• Memory loss
• Difficulty balancing
• Sensitivity to light and sound

Most of the time, you can recover completely from mild brain injuries with rehabilitation. Even though the symptoms are not life-threatening, they should be taken seriously. If the symptoms are ignored, they could get worse and cause more serious health problems, especially if you suffer a second mild TBI before your recovery is complete.

Severe Traumatic Brain Injury

A traumatic brain injury is classified as severe when it results in permanent brain damage. A severe TBI will affect you for the rest of your life. A loss of consciousness longer than 30 minutes and for up to 6 hours is one sign you have suffered a severe TBI. While many of the symptoms of a severe brain injury are similar to a mild injury, their extent is much more permanent. This can include:

• Permanent speech disorders
• Paralysis or difficulty moving
• Decreased sense of smell and taste
• Permanent hearing loss or difficulty hearing

If you or someone you know has experienced a traumatic brain injury, it is important to know that there are chances of recovery.
