Osmotic Demyelination Syndrome (ODS), which includes its well-known subtype Central Pontine Myelinolysis (CPM), is a serious neurologic complication linked to improperly managed hyponatremia. Patients suffering from hyponatremia have an electrolyte imbalance resulting in an abnormally low sodium level.
Although hyponatremia can be treated effectively if diagnosed early, improper or negligent sodium correction can lead to osmotic myelinolysis—the demyelination of nerve fibers in the brain
At Hampton & King, we work with medical experts to identify failures in diagnosing and treating hyponatremia according to standard treatment protocols.
If you or a family member has suffered brain damage, serious injury, or death due to central pontine myelinolysis, our Houston medical malpractice lawyers can help.

How Does a Houston Negligent Sodium Correction Attorney Help in a Medical Malpractice Case?
Sodium correction cases are among the most technical claims in medical malpractice litigation. They require legal representation that can uncover small deviations from proper dosage amounts and accepted standards of care.
An experienced attorney builds your case by:
- Obtaining and reviewing the complete medical record, including every recorded sodium level, physician order, and nursing note tied to your treatment
- Consulting with qualified medical experts to establish the applicable standard of care
- Identifying the specific point where correction happened too quickly or too slowly
- Preparing the expert report Texas law requires early in a malpractice case
- Calculating the full value of your damages, including future care needs
- Negotiating with hospital and physician insurers
- Litigating the case through trial if a fair settlement is not offered
Because these cases depend so heavily on the underlying medicine, having attorneys who understand the clinical details is critical.
What Is Osmotic Demyelination Syndrome?
Osmotic demyelination syndrome (ODS) is also referred to as central pontine myelinolysis (CPM). While they are very similar conditions, ODS is slightly different. It is a neurological disease that is caused when severe damage occurs to the myelin sheath of nerve cells located in the brainstem.
Typically, the damage happens in the area of the brain known as the pons (CPM); however, it can also occur outside of the pons in ODS.
In most cases, CPM results when doctors apply treatment too rapidly by giving patients fluids higher in salt to correct their electrolyte imbalance (hyponatremia). Because CPM usually occurs as a complication associated with treatment for other conditions, it’s often caused by negligence.
The condition can develop in patients who have suffered from serious hyponatremia or conditions that result in decreased liver function.
Complications Associated with Central Pontine Myelinolysis
Hampton & King’s Houston catastrophic injury lawyers represent clients suffering from the following kinds of medical complications and injuries due to CPM:
- Cognitive impairment
- Brain damage
- Double vision
- Speech difficulty
- Confusion
- Muscle spasms
- Tremors
- Hallucinations
- Uncontrollable eye movements
Locked-In Syndrome as a Complication of Osmotic Demyelination Syndrome (ODS)
Locked-in syndrome (LIS) is one of the most devastating potential complications of ODS. It occurs when severe damage to the brainstem, particularly the pons, results in complete paralysis of voluntary muscles except for those controlling eye movements.
Patients are fully conscious and aware but unable to move, speak, or communicate except through blinking or vertical eye movements.
How Does ODS Lead to LIS?
- Damage to the Pons: In ODS, rapid sodium correction can cause demyelination in the brainstem, particularly the pons, which is responsible for motor control, sensory processing, and communication between the brain and body.
- Interruption of Neural Pathways: The damage disrupts the corticospinal and corticobulbar tracts, which control voluntary muscle movement. While cognitive and sensory functions remain intact, the patient loses nearly all ability to move or respond physically.
- Brainstem Integrity: Locked-in syndrome is a result of the preserved integrity of the brainstem’s reticular activating system (responsible for wakefulness and awareness) alongside paralysis of motor functions.
Symptoms of LIS
- Paralysis: Complete loss of voluntary motor function except for the eyes, with patients unable to move their limbs, trunk, or face.
- Eye Movements: Ability to communicate is limited to blinking or vertical eye movements, often used for yes/no responses or aided communication systems.
- Preserved Consciousness: Despite paralysis, patients retain full cognitive function, including awareness of their surroundings and internal thought processes.
Challenges for patients with LIS
- Communication Barriers: Patients require specialized assistive devices, such as eye-tracking systems, to communicate even basic needs.
- Emotional Distress: Being fully conscious but unable to interact with the world can lead to severe psychological challenges, including anxiety, depression, and feelings of isolation.
- Dependency: Patients with LIS require 24/7 care for feeding, hygiene, and medical monitoring.
- Risk of Secondary Complications: Prolonged immobility increases the risk of infections (e.g., pneumonia or urinary tract infections), pressure sores, and blood clots.
While some patients regain partial motor function with intensive therapy, full recovery is exceedingly rare in cases of locked-in syndrome caused by ODS. Care efforts for people with LIS often prioritize improving communication and addressing the patient’s emotional and psychological well-being.
Preventability of Locked-In Syndrome
Locked-in syndrome as a complication of ODS is preventable with proper medical care. Adhering to sodium correction guidelines and monitoring patients carefully during treatment for hyponatremia significantly reduces the risk.
When negligent sodium correction causes ODS and locked-in syndrome, affected patients and their families may have grounds for a medical malpractice claim to seek justice and compensation for their immense suffering.
If you or a loved one has experienced locked-in syndrome due to ODS, consulting with a qualified attorney can help you explore your legal options and secure the resources needed for ongoing care and support.
Contributing Factors to Osmotic Demyelination Syndrome (ODS)
Certain factors can significantly increase the risk of developing ODS during sodium correction. These factors make the brain more vulnerable to osmotic shifts, heightening the importance of careful and gradual treatment.
Patients with extremely low baseline sodium levels (e.g., <120 mmol/L) are at greater risk because their brains have undergone extensive osmotic adaptation. Rapid sodium correction in these cases can overwhelm the brain’s ability to maintain balance, leading to demyelination.
Certain Underlying Conditions That Increase Risk
- Liver Disease: Conditions such as cirrhosis impair the body’s ability to regulate electrolytes and increase vulnerability to osmotic damage.
- Malnutrition: A lack of essential nutrients weakens the brain’s resilience to shifts in sodium levels.
- Chronic Alcoholism: Prolonged alcohol abuse often results in both malnutrition and liver dysfunction, compounding the risk of ODS.
Concurrent Illnesses That Can Increase Risk
- Kidney Failure: Impaired kidney function disrupts electrolyte balance and complicates sodium correction efforts.
- Infections: Systemic infections or sepsis can exacerbate fluid and electrolyte imbalances.
- Metabolic Disorders: Conditions like diabetes or thyroid dysfunction can interfere with the body’s ability to adapt to sodium changes, increasing the likelihood of ODS.
Careful consideration of these contributing factors is crucial when managing sodium correction to minimize the risk of ODS. Healthcare providers must tailor their approach to account for these vulnerabilities and prevent avoidable harm.
What Damages Can I Seek After a Negligent Sodium Correction Injury?
When a hospital or physician mismanages your sodium levels and causes injury, Texas law allows you to pursue compensation for the harm you have suffered. These damages can be financial and/or personal in nature. They may include money for:
- Past medical expenses
- Future medical care
- Any care related to osmotic demyelination syndrome
- Rehabilitation and therapy
- Lost wages and reduced earning capacity
- Pain and suffering
- Emotional distress
- Permanent disability or disfigurement
If negligent sodium correction tragically results in death, surviving family members may pursue a wrongful death claim for their loss. These damages compensate the family and the deceased person’s estate for losses incurred pre-death and those that loved ones will face due to the loss.
Assessing Health Care Provider Negligence & CPM
Since CPM is usually a complication of treatment for hyponatremia, it is typically preventable. The question then arises, what did a doctor do—or fail to do—in treating a patient for low sodium? In most cases, hyponatremia is reversible when recognized and treated properly.
In consultation with medical professionals, our legal team reviews patient records and results of lab tests in order to recreate the decisions and actions of a doctor. In doing so, we can often identify important information that was missed or ignored in failures to properly treat hyponatremia.
Assessing your care begins with sharing your story with a member of our staff. Our Medical Director, who is a full-time MD, will evaluate your case to understand what went wrong and why. She will consult with medical specialists who understand your case, and together our medical and legal professionals will begin to build your claim.
Understanding the merits of your case is only the first step—but it’s one of the most vital when it comes to your success. Few law firms are as equipped as Hampton & King to address your unique situation.
Who Could Be Liable for Negligently Administering Sodium?
Correcting sodium levels safely requires careful coordination between a team of providers. In many cases, more than one provider may share responsibility when something goes wrong.
Potentially liable parties include:
- The treating physician who ordered an incorrect rate of correction or failed to identify the underlying cause of the imbalance
- Nurses who failed to monitor sodium levels frequently enough or failed to flag a dangerous trend to a physician
- Hospital staff that administered the wrong IV fluids or an incorrect concentration of saline
- The hospital for systemic failures
Identifying every liable party often requires a careful review of who made each decision and when. An attorney, working in coordination with a medical expert, can help identify each negligent party in your case.
How Much Does It Cost to Hire a Medical Malpractice Attorney in Houston?
Most medical malpractice attorneys handle these cases on a contingency fee basis. That means there is no upfront retainer and no hourly billing. Moreover, you owe no attorney’s fees unless your law firm recovers compensation on your behalf.
These cases require significant investment in expert witnesses and medical record review; firms typically advance these costs and recover them from any eventual settlement or verdict.
Hampton & King offers contingency fees in all medical malpractice cases. We also provide free consultations to help you understand your rights and legal options.
