What are Some Symptoms of Traumatic Brain Injury?

A hard hit to the head usually causes a traumatic brain injury (TBI), and its symptoms can have debilitating effects. The injury can be quite complex. Besides physical changes, your brain may also undergo chemical changes to compensate for the injury. In mild TBIs, these symptoms are short and do not do much damage to the brain. However, serious TBIs can have long-lasting effects that can manifest in the future without warning.

Common Symptoms of Traumatic Brain Injuries

TBIs are classified as per the mechanism and the severity of the injury. Naturally, symptoms vary as per the condition you are in:

Mild TBI

Individuals who get mild TBIs are usually awake, and their eyes are open. Some of the symptoms they can suffer from include memory loss, disorientation, headaches, and brief fainting spells.

Moderate TBI

People who are diagnosed with moderate TBI can feel lethargic, and their eyes are responsive to stimulation. They may also lose consciousness for 20 minutes or 6 hours, depending on the severity of their injuries. Brain swelling and internal brain bleeds are usually the cause of lethargy.

Severe TBI

Individuals diagnosed with a severe traumatic brain injury lose consciousness, and their eyes do not respond to stimulation. They may remain under for more than six hours.

Types of Traumatic Brain Injuries

Besides the severity of the injury, symptoms can differ as to the type of TBI you have. Some of the common ones include:


A concussion is a mild head injury that can make you faint. However, it rarely causes permanent brain damage.


Contusions are bruises that can manifest in specific areas of the brain and are caused by impacts to the head, such as blunt force trauma. These types of injuries are also called contrecoup or coup injuries. The brain is injured directly right under the area of impact in coup injuries. In contrecoup injuries, the injuries lie on the opposite side of impact. If left untreated, these can lead to disabilities or prove fatal.

Traumatic subarachnoid Hemorrhage (tSAH)

A traumatic subarachnoid hemorrhage (tSAH) is a brain bleed that occurs around the brain. This area is typically filled with cerebrospinal fluid, which cushions the brain against impact. However, in the case of a tSAH, small arteries tear in the brain, and blood starts to spread over the surface. This can lead to widespread effects if the condition is undiagnosed.


A hematoma is a blood clot that can form when a blood vessel ruptures because of blunt force trauma or any impact on the head. The punctured vessels release blood which starts to thicken and clot. A hematoma can be tiny, but it can grow larger and compress the brain as a result. The symptoms can differ as per the location of the clot, which may need to be removed via surgery depending on its size. The bloodstream usually absorbs smaller ones.
