What Is a Mild Concussion?
A mild concussion (also called a mild traumatic brain injury or mTBI) occurs when a blow, bump, or jolt to the head temporarily disrupts normal brain function. Despite being called “mild,” these injuries can cause significant symptoms and affect your quality of life.
Common Symptoms of Mild Concussion
| Physical Symptoms | Cognitive Symptoms | Emotional Symptoms |
|---|---|---|
| Headache | Confusion | Irritability |
| Dizziness | Memory problems | Anxiety |
| Nausea/vomiting | Difficulty concentrating | Depression |
| Balance problems | Feeling “foggy” | Mood swings |
| Fatigue | Slow thinking | Emotional outbursts |
| Light sensitivity | Trouble finding words | Personality changes |
| Noise sensitivity | Disorientation | Sleep disturbances |
Causes of Mild Concussions
- Car accidents: Head striking steering wheel, window, or whiplash motion
- Slip and fall accidents: Head hitting ground or objects
- Sports injuries: Football, soccer, hockey, basketball impacts
- Workplace accidents: Falling objects, machinery incidents
- Assaults: Punches, blows to the head
- Motorcycle accidents: Even with helmets, brain can shake inside skull
How Mild Concussions Are Diagnosed
Doctors diagnose concussions through:
- Symptom evaluation: Questions about what happened, how you feel
- Neurological exam: Testing reflexes, balance, coordination, memory
- Cognitive testing: Assessing memory, concentration, processing speed
- CT scan: To rule out bleeding or skull fracture (may appear normal with concussion)
- MRI: More detailed imaging if symptoms persist
Important: Many concussions don’t show up on CT or MRI scans. A normal scan does NOT mean you don’t have a concussion. Some people have undiagnosed brain injuries that aren’t discovered for years.
Factors That Determine Concussion Settlement Value
1. Medical Expenses
| Treatment Type | Average Cost | Settlement Impact |
|---|---|---|
| Emergency room visit | $1,500 – $5,000 | Establishes injury documentation |
| CT scan | $500 – $3,000 | Rules out severe injury |
| MRI | $1,000 – $5,000 | Detects subtle brain changes |
| Neurologist consultations | $200 – $500/visit | Specialist documentation |
| Neuropsychological testing | $2,000 – $5,000 | Proves cognitive deficits |
| Physical therapy | $100 – $300/session | Demonstrates ongoing treatment need |
| Cognitive rehabilitation | $150 – $400/session | Documents functional impairment |
2. Lost Wages and Earning Capacity
- Time off work: Days/weeks missed during recovery
- Reduced hours: Part-time return before full recovery
- Job loss: If symptoms prevent return to prior position
- Future earning capacity: If cognitive deficits affect career advancement
3. Pain and Suffering
- Physical pain from headaches, dizziness, nausea
- Emotional distress from symptoms
- Loss of enjoyment of activities
- Impact on relationships and social life
- Anxiety about long-term effects
4. Symptom Duration and Severity
| Recovery Timeline | Settlement Multiplier | Typical Scenario |
|---|---|---|
| Full recovery in 1-2 weeks | 1-2x medical bills | Mild symptoms, quick return to normal |
| Recovery in 1-3 months | 2-3x medical bills | Moderate symptoms, some work impact |
| Symptoms persist 3-6 months | 3-5x medical bills | Post-concussion syndrome developing |
| Symptoms beyond 6 months | 5-10x+ medical bills | Chronic PCS, major life impact |
Post-Concussion Syndrome: When Symptoms Don’t Go Away
About 10-15% of concussion patients develop post-concussion syndrome (PCS), where symptoms persist for months or years. PCS significantly increases settlement value because it demonstrates:
- Ongoing medical treatment needs
- Permanent or long-lasting impairment
- Substantial impact on quality of life
- Future medical expenses
PCS symptoms include persistent headaches, chronic dizziness, ongoing cognitive difficulties, sleep disturbances, and emotional changes. These cases often require expert testimony from neurologists and neuropsychologists.
Illinois Statute of Limitations for Concussion Claims
| Claim Type | Time Limit | Illinois Statute |

| Personal injury (car accident, slip & fall) | 2 years from injury date | 735 ILCS 5/13-202 |
| Workers’ compensation | 3 years (or 2 years from last benefit) | 820 ILCS 305/6 |
| Medical malpractice | 2 years from discovery (4 years max) | 735 ILCS 5/13-212 |
| Claims against government | 1 year from injury | 745 ILCS 10/8-101 |
Frequently Asked Questions
What is the average concussion settlement value?
The average concussion settlement ranges from $20,000 to $100,000. Simple concussions with quick recovery average $25,000-$40,000. Concussions with post-concussion syndrome or lasting effects can reach $100,000-$300,000 or more.
Can I sue for a mild concussion?
Yes, you can sue for a mild concussion if someone else’s negligence caused your injury. This includes car accidents, slip and falls, workplace incidents, sports injuries, or assaults. You’ll need to prove the other party was at fault and your concussion resulted from their actions.
How long do I have to file a mild concussion claim in Illinois?
In Illinois, you have 2 years from the date of injury to file a personal injury lawsuit for a concussion. For workers’ compensation claims, you have 3 years. Don’t wait—evidence becomes harder to gather and memories fade over time.
What if my concussion symptoms get worse over time?
If your symptoms worsen, see a doctor immediately and document everything. Worsening symptoms may indicate post-concussion syndrome or a more serious underlying injury. This documentation can significantly increase your settlement value.
How is post-concussion syndrome settlement different from regular concussion?
Post-concussion syndrome (PCS) settlements are typically 3-5 times higher than standard concussion settlements because symptoms persist for months or years. PCS cases average $100,000-$300,000 compared to $20,000-$40,000 for concussions with full recovery.
Long-Term Effects to Consider
Even “mild” concussions can have lasting effects, especially if you’ve had multiple concussions or didn’t receive proper treatment. Long-term concerns include:
- Increased risk of future concussions
- Chronic traumatic encephalopathy (CTE) with repeated injuries
- Persistent cognitive difficulties
- Higher risk of depression and anxiety
- Memory and concentration problems
