You may be showing signs of a concussion or traumatic brain injury (TBI). At Griffin Law Firm, P.C., we want to make sure that you know what to look for after a crash. Here, our Snellville car accident attorney provides a guide for recognizing the symptoms of a concussion after a traffic collision in Georgia.

Know the Most Common Concussion Symptoms After a Car Accident

Concussions are challenging to diagnose. Not only do they manifest with a delayed onset in many cases, but the prognosis can vary from person to person. The specific part of the brain that was affected will play a role in how the injury presents itself. Here are some of the most common symptoms of a concussion from a car crash:

  • Headache and Pressure in the Head: Headaches are often the earliest and most noticeable symptom following a concussion. The pain may start as a dull ache and gradually intensify over time. Medically, post-traumatic headaches are caused by chemical and vascular changes within the brain after mechanical injury to neuronal tissue. The stretching of blood vessels and irritation of pain-sensitive meninges contribute to this discomfort. Persistent or worsening headaches (especially when accompanied by nausea or confusion) should be treated as a sign of a possible concussion.
  • Dizziness and Loss of Balance: Another common symptom is dizziness. Many car accident victims report feeling lightheaded or unsteady after a head impact. Dizziness can occur immediately or develop later as swelling or inflammation affects brain function. From a clinical perspective, this symptom results from disruption to the vestibular system. That system includes structures of the inner ear and brainstem that are responsible for spatial orientation and balance. Concussions interfere with the transmission of sensory signals that help the brain coordinate movement.
  • Nausea and Vomiting: Nausea and/or vomiting after a car crash is a big sign of a concussion. In fact, it is common for concussion patients to feel sick to their stomach or vomit shortly after the incident. These symptoms often accompany severe headaches or dizziness. Physiologically, nausea and vomiting stem from increased intracranial pressure and disruption of the autonomic nervous system. The area postrema (a part of the brain that controls vomiting) can become overstimulated following trauma from a crash.
  • Cognitive Impairment and Confusion: After a concussion, it may feel hard to think clearly, concentrate, or remember what happened during or after the crash. Victims sometimes describe feeling “foggy” or detached. The condition reflects a temporary diffuse axonal injury, where stretching of nerve fibers disrupts normal communication between neurons. Such microstructural damage impairs the brain’s ability to process and store information efficiently. Neurocognitive testing and imaging may reveal slowed reaction times and deficits in executive functioning.
  • Short-term Memory Loss: After a concussion, many people struggle to remember details of the accident or events shortly before and after it. This confusion can be frightening, but it is a well-documented neurological effect. The underlying cause is a temporary disruption of the hippocampus and frontal lobe. These are the regions responsible for forming and retrieving new memories.
  • Sensitivity to Light and/or Noise: Bright lights or loud sounds may suddenly feel overwhelming after a concussion. The symptom is known as photophobia (light sensitivity) and phonophobia (sound sensitivity). On a neurological level, concussions disturb the brain’s sensory integration pathways, particularly within the thalamus and occipital cortex, which regulate visual and auditory processing. The overstimulation of these neural circuits causes discomfort and fatigue when exposed to otherwise normal environmental stimuli.

Understanding Second Impact Syndrome

As explained by the Mayo Clinic, Second Impact Syndrome occurs when a person sustains a second concussion before the first one has fully healed. The brain loses its ability to regulate blood flow, leading to rapid swelling and catastrophic pressure inside the skull. The good news is that the condition is relatively rare. The bad news is that it is a very serious medical emergency. If you or your loved one is dealing with Second Impact Syndrome, our Snellville car accident lawyers are here to help you navigate a claim.

Frequently Asked questions

What if I was partially at fault for the accident?

There is a comparative negligence rule in Georgia. The rule allows victims to recover damages if they are found to be less than 50% at fault. However, it is important to note that your compensation will be lowered by your percentage of fault.

How much is my personal injury case worth?

The value of your case depends on many factors, including the severity of your injuries, medical expenses, lost wages, and pain and suffering. An experienced Snellville personal injury attorney can provide a more accurate estimate after reviewing your case details.

Will my personal injury case go to trial?

Most personal injury cases settle out of court. However, if the insurance company doesn’t offer a fair settlement, we are prepared to take your case to trial to fight for the compensation you deserve.

At Griffin Law Firm, we work on a contingency fee basis. This means that victims don’t have to pay any upfront costs, as we only get paid if we win your case. Our fee is typically a percentage of your settlement or court award.
