Concussion Injury Claims in Michigan

A concussion may be classified as a "mild" traumatic brain injury, but there is nothing mild about living with one. Concussions from car accidents, falls, and other impacts can produce debilitating symptoms lasting months or years, destroying careers, relationships, and quality of life. Because concussions do not show up on standard CT scans or MRIs, insurance companies routinely minimize these injuries. Understanding how to document, prove, and value a concussion claim in Michigan is essential for victims who face an uphill battle against skeptical insurers.

Understanding Post-Concussion Syndrome

Most concussions resolve within two to four weeks. However, approximately 15-30% of concussion patients develop post-concussion syndrome (PCS), where symptoms persist for months or even become permanent. PCS transforms what might seem like a minor injury into a life-altering condition.

Common post-concussion syndrome symptoms include:

• Persistent headaches (often daily)
• Dizziness and balance problems
• Fatigue that does not improve with rest
• Light and noise sensitivity
• Sleep disturbances (insomnia or excessive sleeping)
• Irritability and personality changes
• Difficulty concentrating and "brain fog"
• Memory problems, particularly short-term memory
• Anxiety and depression
• Visual disturbances including blurred vision

PCS is diagnosed when concussion symptoms persist beyond the expected recovery window and interfere with daily functioning. Risk factors for developing PCS include prior concussions, female sex, older age, pre-existing anxiety or depression, and high initial symptom severity. However, PCS can develop in anyone following a concussion.

Cognitive Deficits: Memory, Concentration, and Processing Speed

The cognitive effects of concussions are often the most disabling aspect of the injury, particularly for knowledge workers whose livelihoods depend on mental acuity. Three categories of cognitive impairment commonly result from concussions:

Memory deficits: Concussion patients frequently report difficulty forming new memories (anterograde memory problems). They forget conversations, miss appointments, lose track of tasks, and cannot retain new information as effectively as before the injury. This affects job performance, academic achievement, and daily functioning.

Concentration and attention: Sustained attention becomes difficult after a concussion. Patients describe inability to focus on reading, maintain attention in meetings, follow complex conversations, or multitask. Activities that were previously automatic now require conscious effort and are exhausting.

Processing speed: The brain processes information more slowly after a concussion. Patients need more time to understand instructions, formulate responses, make decisions, and react to situations. This slowing is often subtle but profoundly affects professional performance, particularly in fast-paced work environments.

These cognitive deficits may not be immediately obvious to others, making them particularly frustrating for patients who appear physically healthy but cannot perform at their previous level. Coworkers, family members, and even the patients themselves may attribute the difficulties to stress or laziness rather than brain injury.

Neuropsychological Testing: Objective Proof of Brain Injury

Neuropsychological testing is the gold standard for documenting cognitive deficits from concussions. A neuropsychologist administers a battery of standardized tests measuring various cognitive functions including memory, attention, processing speed, executive function, language, and visual-spatial ability.

The testing typically takes four to eight hours and produces objective, quantifiable data showing exactly where your cognitive performance falls compared to expected norms for your age and education level. For example, testing might reveal that your processing speed has dropped from the 75th percentile (above average) to the 25th percentile (below average) following your concussion.

This testing is critically important for legal claims because it:

1. Provides objective, measurable evidence of brain dysfunction that cannot be dismissed as subjective complaints
2. Identifies the specific cognitive domains affected by the concussion
3. Quantifies the severity of impairment in standardized terms
4. Establishes a baseline that can be compared to later testing to track recovery or deterioration
5. Includes validity measures that detect malingering or exaggeration, lending credibility to genuine results

If you are pursuing a concussion claim, request a referral to a neuropsychologist early in your treatment. Testing performed within the first few months after injury captures deficits at their worst and establishes the foundation for your legal case.

Return-to-Work Challenges

Returning to work after a concussion is often far more difficult than patients or employers expect. Cognitive fatigue, headaches triggered by screen use, difficulty concentrating in noisy environments, and reduced processing speed all impair work performance.

Common workplace difficulties following concussion include:

• Inability to work full days due to cognitive fatigue
• Difficulty with computer screens triggering headaches and visual symptoms
• Problems in meetings requiring sustained attention and rapid information processing
• Errors in work that was previously routine
• Inability to meet deadlines due to slowed processing
• Difficulty managing multiple projects simultaneously
• Social withdrawal from coworkers due to irritability and overwhelm

Some concussion patients require gradual return-to-work protocols, reduced hours, modified duties, or workplace accommodations. Others find they can no longer perform their previous job at all and must transition to less demanding work at lower pay. These employment impacts represent significant economic damages in a legal claim.

Multiple Concussion Risks

Research demonstrates that each subsequent concussion causes disproportionately greater damage. A brain recovering from a concussion is significantly more vulnerable to repeat injury, a phenomenon sometimes called "second impact syndrome" in its most severe form. People with concussion history are more likely to experience longer recovery times, more severe symptoms, and permanent cognitive impairment with each additional concussion.

This is legally relevant because if you had a prior concussion history before the accident, the at-fault party is responsible for taking you as they found you under Michigan's "eggshell skull" doctrine. Your vulnerability to more severe concussion effects does not reduce the defendant's liability. In fact, it increases your damages because the concussion's impact is worse due to your history.

Conversely, if the accident concussion leaves you more vulnerable to future brain injury, that increased vulnerability and the restrictions it necessitates (avoiding contact sports, using greater caution) are compensable damages.

Proving Invisible Injuries

The central challenge in concussion litigation is that the injury is invisible. Standard CT scans and conventional MRIs typically appear normal after a concussion because the damage occurs at the cellular and metabolic level, not as a visible structural lesion. Insurance companies exploit this by arguing "if we cannot see it, it does not exist."

Successful concussion claims overcome this challenge through multiple evidence sources:

• Neuropsychological testing: Objective cognitive deficit documentation as described above
• Advanced neuroimaging: DTI (diffusion tensor imaging), fMRI, and SPECT scans can sometimes reveal microstructural damage not visible on conventional imaging
• Consistent medical records: Ongoing documentation of symptoms reported to multiple providers over time
• Witness testimony: Family members, coworkers, and friends describing observable changes in behavior, personality, and cognitive function
• Employment records: Performance reviews, errors, disciplinary actions, or job loss following the concussion
• Academic records: Grade drops, withdrawal from courses, or inability to complete education
• Before-and-after comparison: Demonstrating high functioning before the accident versus diminished functioning after

Michigan's Serious Impairment Threshold for Concussion Claims

Under MCL 500.3135, Michigan requires auto accident victims to demonstrate a "serious impairment of body function" before they can recover pain and suffering damages from the at-fault driver. The statute defines this as an objectively manifested impairment of an important body function that affects the person's general ability to lead their normal life.

Concussion claims face particular scrutiny under this threshold because of the invisible nature of the injury. To meet the standard, you must demonstrate:

1. Objectively manifested: The impairment must be evidenced by objective findings, not just subjective complaints. Neuropsychological test results, documented cognitive deficits, and consistent medical records satisfy this element.
2. Important body function: Brain function is unquestionably an important body function. Cognitive ability, memory, and concentration are essential for virtually all human activities.
3. Affects general ability to lead normal life: You must show that the concussion effects actually changed your daily life. Evidence of inability to work, relationship problems, abandoned hobbies, social withdrawal, and lost independence all demonstrate this element.

Michigan courts have recognized that post-concussion syndrome can meet the serious impairment threshold when properly documented. The key is building a comprehensive medical and functional record demonstrating the real-world impact of your cognitive deficits.

Michigan's three-year statute of limitations applies to concussion claims. Your no-fault PIP benefits cover medical treatment including neuropsychological evaluation, cognitive rehabilitation therapy, vestibular therapy, and mental health treatment related to the concussion. Do not delay seeking treatment or legal consultation, as early documentation is the foundation of a successful concussion claim.
