What Brain Injury Misdiagnosis Looks Like in a Medical Setting

Brain injury misdiagnosis happens when a doctor either identifies the wrong condition or fails to recognize a brain injury at all. A patient may come into an emergency room at Northwestern Memorial Hospital or Rush University Medical Center with headaches, confusion, and nausea. Instead of ordering a CT scan or MRI, the doctor sends them home with a diagnosis of stress, anxiety, or a simple headache. Days later, the patient collapses from a subdural hematoma or a brain bleed that was present all along.

Misdiagnosis is not limited to missing a TBI after a car accident on the Dan Ryan Expressway or a fall near Millennium Park. It also includes cases where a doctor incorrectly labels a brain tumor as migraines, or mistakes the cognitive symptoms of a brain hemorrhage for a psychiatric condition. In some cases, a patient is told they have a stroke when they actually have a brain tumor, or vice versa. Each of these errors can lead to the wrong treatment, making the patient’s condition significantly worse.

Research published in the National Institutes of Health database found that persons with severe brain injury face a 41% misdiagnosis rate, meaning they do not receive a basic standard of care available to others. That number is alarming on its own. When you consider that these are some of the most vulnerable patients in any hospital, the stakes become even clearer.

According to the CDC, there were approximately 214,110 TBI-related hospitalizations in 2020 and 68,663 TBI-related deaths in 2023, representing more than 586 TBI-related hospitalizations and 190 TBI-related deaths per day. When even a fraction of those cases involve misdiagnosis, the human cost is enormous. Brain injury misdiagnosis is not a rare edge case. It is a pattern that shows up in emergency rooms, neurology clinics, and primary care offices across Chicago and throughout Illinois.

How Illinois Law Defines Medical Malpractice in Brain Injury Cases

Medical malpractice in Illinois is governed by the abogado de negligencias médicas framework established under Illinois law, which requires proving that a healthcare provider deviated from the accepted standard of care. In a brain injury misdiagnosis case, that means showing that a reasonably competent doctor, given the same patient presentation, would have ordered the right tests, interpreted the results correctly, and reached the right diagnosis.

Four core elements must be established in any Illinois medical malpractice claim. First, a doctor-patient relationship must have existed. Second, the doctor must have breached the standard of care. Third, that breach must have directly caused harm to the patient. Fourth, the patient must have suffered measurable damages as a result. All four elements must be present. A bad outcome alone does not automatically mean malpractice occurred.

Illinois also has a specific pre-filing requirement under 735 ILCS 5/2-622, the Healing Art Malpractice statute. This law requires that before filing a medical malpractice complaint, the plaintiff’s attorney must attach an affidavit confirming that a qualified health professional reviewed the case and determined there is a reasonable and meritorious basis for the claim. That reviewing professional must be knowledgeable in the relevant area of medicine, must have practiced or taught in that area within the last six years, and must provide a written report supporting the case. This requirement exists to screen out frivolous claims and to ensure that legitimate cases are backed by real medical evidence from the start.

En 735 ILCS 5/2-1117, Illinois also addresses how liability is shared among multiple defendants. Any defendant found to be 25% or more at fault is jointly and severally liable for all damages, including medical expenses. A defendant found less than 25% at fault is only severally liable for non-medical damages. This matters in brain injury cases where multiple providers, such as an emergency room physician, a radiologist, and a neurologist, each played a role in the misdiagnosis.

Common Causes of Brain Injury Misdiagnosis in Chicago Hospitals

Brain injuries are misdiagnosed for a range of reasons, and understanding those reasons helps identify where the negligence occurred. The CDC notes that TBIs may be missed or misdiagnosed in older adults because symptoms of TBI overlap with other conditions common in that age group. But misdiagnosis affects patients of all ages and backgrounds, not just the elderly.

One of the most common causes is a failure to order appropriate diagnostic testing. A doctor who sees a patient complaining of a severe headache after a fall near the Chicago Riverwalk should be ordering imaging. Skipping that step, or ordering the wrong type of scan, can allow a brain bleed or contusion to go undetected. Related to this is a failure to interpret imaging results correctly. A radiologist who misreads a CT scan or MRI may clear a patient who actually has a serious intracranial injury.

Symptom overlap is another major factor. Brain injuries can mimic psychiatric conditions, inner ear disorders, or simple concussions. A patient who presents with mood changes, memory problems, or dizziness may be sent to a psychiatrist rather than a neurologist. The CDC also notes that TBIs may be missed because symptoms overlap with other conditions, which is especially true in busy urban emergency departments where doctors are moving quickly between patients.

Inadequate patient history-taking plays a role as well. If a patient does not clearly communicate a recent head trauma, or if the treating physician does not ask the right questions, a brain injury can be overlooked entirely. Communication failures between departments, such as a failure to communicate critical test results from radiology to the treating physician, also contribute to delayed or missed diagnoses. Each of these failures can form the basis of a malpractice claim when they result in patient harm.

Illinois Filing Deadlines for Brain Injury Misdiagnosis Claims

Time limits are critical in any medical malpractice case, and brain injury misdiagnosis claims are no exception. Under 735 ILCS 5/13-212(a), an Illinois medical malpractice action generally must be brought within two years after the claimant knew, or through reasonable diligence should have known, of the injury or death. In most cases, there is also a four-year outside limit from the act or omission itself.

The discovery rule is especially relevant in brain injury misdiagnosis cases. A patient who was sent home from a Chicago-area hospital with an incorrect diagnosis may not realize for months that their ongoing symptoms are the result of an untreated brain injury. The Illinois Supreme Court in Moon v. Rhode (2016 IL 119572) confirmed that the limitations period begins only when the plaintiff has reason to connect the injury to negligent medical care, not merely when they are aware of an adverse medical outcome. That distinction matters, because many brain injury patients spend months seeking answers before they understand what actually went wrong.

However, the four-year statute of repose is an absolute deadline. Illinois law imposes an absolute deadline: no medical malpractice action can be brought more than four years after the date on which the alleged act or omission occurred. After four years from the date of the malpractice, claims are barred regardless of when the injury was discovered.

For minors, 735 ILCS 5/13-212(b) allows more time, generally up to eight years after the act or omission, but not after the minor’s 22nd birthday. If a child suffers a brain injury misdiagnosis, parents should act as soon as possible rather than waiting for the extended deadline. Evidence fades, witnesses move on, and medical records become harder to obtain over time. If you believe a misdiagnosis occurred, speaking with a abogado de negligencia médica promptly is the most important step you can take.

What Damages Are Available in a Brain Injury Misdiagnosis Case

Victims of brain injury misdiagnosis in Illinois can pursue several categories of compensation. Economic damages cover the financial losses that can be calculated and documented. These include past and future medical bills, rehabilitation costs, lost wages, and the expense of long-term care. A patient who suffers permanent cognitive damage due to a delayed diagnosis of a brain hemorrhage may require years of occupational therapy, in-home care, or assisted living. Those costs add up quickly, and they are fully recoverable in a successful malpractice claim.

Non-economic damages cover the human cost of the injury. Pain and suffering, emotional distress, loss of enjoyment of life, and loss of companionship for a spouse or family member all fall into this category. Brain injuries often affect a person’s personality, memory, and ability to maintain relationships. These losses are real, even if they cannot be shown on a medical bill.

In cases where a brain injury misdiagnosis leads to death, the patient’s family may bring a wrongful death claim under the Illinois Wrongful Death Act (740 ILCS 180). This allows surviving family members to recover compensation for the grief, loss of support, and financial harm caused by the death. Families in neighborhoods from Lincoln Park to Beverly to Pilsen have faced this situation, and Illinois law provides a path to accountability.

Under 735 ILCS 5/2-1117, all defendants found liable are jointly and severally liable for a plaintiff’s past and future medical and medically related expenses. This means that even if multiple providers share fault, the patient can pursue full medical cost recovery from any defendant found to be significantly at fault. Connecting with a abogado de negligencias médicas who understands how to build a damages case is essential to recovering what you are owed.

Why Brain Injury Misdiagnosis Cases Require Experienced Legal Representation

Brain injury misdiagnosis cases are among the most medically and legally complex claims in the personal injury field. They require a thorough review of imaging studies, emergency room records, neurology consult notes, and nursing documentation. They also require expert witnesses who can testify about what a competent physician should have done differently. Without that foundation, a case is difficult to win.

Illinois requires the 735 ILCS 5/2-622 affidavit from a qualified health professional before the case can even be filed. That means the legal team must identify and work with a credentialed medical expert early in the process. The expert must have practiced or taught in the relevant area of medicine within the last six years and must be qualified by experience or demonstrated competence in the specific type of case being filed.

Chicago’s Cook County Circuit Court, located in the Richard J. Daley Center at 50 W. Washington Street, is where many of these cases are litigated. Understanding how Cook County courts handle medical malpractice claims, including local rules, judicial preferences, and jury composition in the Chicago area, is a genuine advantage when preparing a case for trial or settlement negotiations.

FAQs About Brain Injury Misdiagnosis Medical Malpractice in Chicago

What is the difference between a missed brain injury diagnosis and a brain injury misdiagnosis?

A missed diagnosis means the doctor failed to identify a brain injury at all, sending the patient home without any diagnosis. A misdiagnosis means the doctor identified a different condition, such as anxiety or migraines, when the patient actually had a brain injury. Both can form the basis of a medical malpractice claim in Illinois if the error caused harm and fell below the accepted standard of care.

How do I know if my doctor’s mistake rises to the level of medical malpractice?

Not every diagnostic error is malpractice. To have a valid claim under Illinois law, you must show that the doctor’s conduct fell below what a reasonably competent physician would have done under similar circumstances, and that this failure directly caused measurable harm to you. A qualified medical expert must review your case and confirm there is a meritorious basis before a lawsuit can be filed under 735 ILCS 5/2-622. The best way to find out if your situation qualifies is to speak with an attorney who handles medical malpractice claims.

Can I still file a claim if the misdiagnosis happened several years ago?

It depends on when you discovered, or reasonably should have discovered, that the misdiagnosis caused your injury. Under 735 ILCS 5/13-212(a), you generally have two years from that discovery date to file. However, no claim can be filed more than four years after the date of the negligent act, regardless of when you found out. There are limited exceptions, including cases involving minors or fraudulent concealment by the provider. Speaking with an attorney as soon as possible is the safest approach.

What types of brain injuries are most commonly misdiagnosed?

Subdural hematomas, brain hemorrhages, concussions, and brain tumors are among the most frequently misdiagnosed brain conditions. Concussions are often dismissed as minor issues when they actually require careful monitoring and follow-up. Subdural hematomas and brain bleeds are sometimes mistaken for migraines, stroke, or psychiatric conditions, especially in older patients. Brain tumors may be misidentified as tension headaches or sinus issues for months before the correct diagnosis is made.

What should I do right now if I think a brain injury was misdiagnosed?

Start by getting a second medical opinion from a neurologist or specialist who can review your current condition and imaging. Gather all medical records, including emergency room notes, imaging results, and discharge paperwork. Write down a timeline of your symptoms, the care you received, and how your condition has changed. Then contact an attorney as soon as possible. Briskman Briskman & Greenberg offers free consultations and can be reached at (312) 222-0010. Early action protects your legal rights and preserves the evidence needed to build a strong case.
