You walk away from an accident thinking you got lucky. No broken bones. No obvious injuries. Maybe just a headache and a little soreness. A few days later, you can't focus. You forget simple things. The headaches won't go away. Suddenly, getting through a normal workday feels impossible. Brain injuries don't always announce themselves right away. Knowing the signs of a brain injury after an accident can help you recognize when something isn't right and when it's time to seek medical attention.
If you experience a jolt or impact to the head, you are at risk of suffering a traumatic brain injury (TBI). Both of these actions cause the brain to move rapidly inside the skull. That disrupts normal brain function and causes injury. In car accidents, closed TBIs are more common than penetrating brain injuries. A closed TBI happens when there is no break to the skull, so there is no open wound on the head.
In a car accident, you may experience primary and secondary brain injuries. The primary injury is when the initial accident occurs. The secondary injuries are what happen to the brain in the days or weeks following the accident.
TBIs are classified into three levels: mild, moderate, and severe. The Glasgow Coma Scale (GCS) is used to determine the severity of a TBi in patients. A concussion is a mild form of TBI. You may lose consciousness and memory of the events immediately before or after the accident. Moderate TBi injuries typically cause loss of consciousness and memory for 30 minutes to one week. Severe TBIs are typically characterized by loss of consciousness and memory greater than one week.
Immediately following a car accident, there are several signs to look out for that would signal someone suffering a TBI. They may have a headache, be dizzy, vomit, have blurred vision, or be sensitive to light. Losing consciousness is also a clear sign of a brain injury.
Sometimes, the signs of a TBI aren’t physical, but cognitive. They may exhibit confusion with an inability to concentrate or process information. They may have trouble with their memory and recalling basic information. Emotional changes can also take place, such as being irritable, anxious, or depressed. Strong mood swings can also be a sign.
Just because someone doesn’t exhibit any of the initial signs at the accident scene doesn’t mean they don’t have a TBI. The body releases adrenaline when a “fight or flight” response is triggered. A car accident is a sudden and jarring experience that can trigger survival instincts in people. The release of adrenaline, plus the initial shock of the accident, can mask the signs of a brain injury at the accident scene.
Additionally, inflammation, bruising, and bleeding can develop, becoming worse over time. You may experience memory issues, persistent headaches, and personality changes. Trouble sleeping is also common. Sensitivity to lights and sounds can also increase over time. Sometimes, it isn’t these specific symptoms, but an overall increased struggle to perform well at school or work.
Seeking treatment early on helps to improve long-term healing outcomes. Seeking treatment also helps with establishing a medical history, making it easier to connect the TBI to the accident. Do not wait if you experience any combination of these TBI symptoms.
The long-term effects of a traumatic brain injury are often difficult to predict in the days and weeks following an accident. While some symptoms improve over time, others may become permanent. Chronic headaches, cognitive impairments, memory loss, emotional changes, and reduced earning capacity are all potential consequences of a serious brain injury.
These lasting effects can impact a person's ability to work, manage household responsibilities, maintain relationships, and enjoy daily life. These unique challenges can impact the settlement negotiations.
What may seem like a minor headache or temporary confusion after an accident can develop into symptoms that affect your ability to work, maintain relationships, and handle everyday responsibilities. Recognizing the warning signs and getting prompt medical care is one of the most important steps you can take. Our firm works to build strong cases supported by medical records, expert opinions, and evidence of how the injury has affected your life.
