Traumatic brain injury (TBI) is an extremely serious injury that may result in a car accident. Such a brain injury occurs when the external force of a car accident traumatizes the brain. Brain injury may lead to permanent or temporary impairment of the brain’s functions. Skull fractures, bruises of the brain (hematoma), and nerve damage are often related to such brain injury.

Brain injuries are more common in side impact car accidents than in rear-end auto accidents. Brain damage in a car accident is often related to the quick acceleration and deceleration of the brain, which causes injury to the point of impact and its opposite point or contrecoup. Diagnosis of a brain injury may be difficult. Concussions are associated with traumatic brain injury as are seizures, headaches, dizziness, lack of concentration, memory loss, depression or anxiety. CT scans and MRI scans are often used to diagnosis brain injury.

Neck injuries vary from whiplash, one of the most common and annoying injuries caused by car accidents, to disk injuries. Whiplash is an injury frequently associated with rearend impacts. Whiplash injures the soft tissues made up of nerves, ligaments and muscles. It causes neck pain and limitation of neck and head movement effecting rotation and peripheral vision. It may be temporary or permanent and can effect all aspects of life. If whiplash lasts for more than a few days after a car accident physicians will prescribe medications and often refer patients to physical therapists or chiropractors for rehabilitative therapy.

Temporalmandibular joint (TMJ) injury is an injury to the joint and ligaments that allow the jaw to move. Similar to whiplash, the TMJ joint is injured in the acceleration and deceleration of a car accident. This may occur with direct or indirect injury to the jaw and effects chewing, eating and speech.

Intervertebral discs make up the spine. The disks lie between each bone (vertebrae) in the spine and form joints giving spines flexibility. Discs are made up of an outer skin called an annulus that surround the inner nucleus, a jelly like substance. If the annulus is torn, a disc may herniate and need surgery. Disks in the neck and spine may bulge, slip or rupture, hence the phrases bulging disc, slipped disc, and ruptured disc. CT scans and MRI scans are often used to diagnosis disc injuries and because such tests are expensive doctors will not order them immediately after a car accident. It frequently occurs where a disk injury or herniated disc is not diagnosed until months after a car accident.
