She Thought She Had Dementia — Then a Brain Scan Revealed Something Unexpected

A Texas woman spent years believing she was losing her memory to dementia. Her headaches were unbearable, walking became difficult, and everyday tasks turned into exhausting challenges. Doctors even suggested she might eventually need nursing home care.

But when a specialist took another look at her brain scan, he noticed something that had previously gone undetected.

Her brain appeared to be sagging.

And the cause wasn’t Alzheimer’s disease or another typical form of dementia.

Instead, doctors discovered a rare spinal fluid leak that was interfering with the normal support and functioning of her brain.

The remarkable medical mystery, involving a woman named Debra Roberts from Spring, Texas, highlights a condition that can sometimes mimic dementia yet may be treatable when properly identified.

It Started With Severe Headaches — Then Everything Changed

In 2017, Debra Roberts woke up experiencing severe headaches and difficulty walking.

At first, the symptoms were mysterious. She had no obvious explanation for why her health had suddenly deteriorated.

Over the following years, her condition continued to worsen.

She experienced persistent headaches, dizziness, ringing in her ears, and difficulty sleeping.

Roberts underwent neurological examinations, CT scans, and MRI testing, but the initial investigations failed to provide a clear diagnosis.

Meanwhile, her symptoms were becoming increasingly disruptive.

By 2020, she had developed serious memory problems.

Roberts worked as a technician in a cardiac catheterization laboratory at Houston Methodist The Woodlands Hospital. Eventually, she became so concerned about her ability to perform her duties safely that she took a leave of absence.

Her memory loss was especially frightening.

At one point, she could barely remember her son’s wedding.

Doctors began considering whether she had early-onset dementia or Alzheimer’s disease.

The possibility was devastating.

Roberts was reportedly advised to prepare for the possibility of moving into a nursing home.

Yet her husband, Rick, remained unconvinced that dementia fully explained what was happening.

A Doctor Looked at Her Brain Scan Again — And Spotted Something Unusual

After years of searching for answers, Roberts consulted neuroradiologist Dr. David Badger in Houston.

She asked him to review an MRI of her brain taken in 2020.

This time, a subtle but important abnormality caught his attention.

The position of her brain was not normal.

It appeared to have shifted downward toward the opening at the base of the skull.

Doctors call this phenomenon brain sagging.

Brain sagging can occur when the pressure or volume of cerebrospinal fluid surrounding the brain becomes abnormally low.

In Roberts’ case, the finding raised suspicion that spinal fluid was escaping somewhere along her spine.

That discovery completely changed the direction of her medical investigation.

Instead of focusing primarily on an irreversible neurodegenerative disease, doctors began searching for a potentially treatable structural problem.

What Is a Cerebrospinal Fluid Leak?

The brain and spinal cord are surrounded by a clear liquid known as cerebrospinal fluid, or CSF.

This fluid performs several important functions.

It cushions the brain against mechanical forces, helps maintain a stable environment for the nervous system, and contributes to the transport of nutrients and waste products.

The brain effectively floats within this protective fluid.

When cerebrospinal fluid escapes from its normal enclosed space, the loss of fluid can alter the way the brain is supported.

In some people, this leads to a condition known as spontaneous intracranial hypotension, often abbreviated as SIH.

Despite the name, not every person with the condition has measurably low cerebrospinal fluid pressure.

The underlying problem is frequently a loss of fluid volume caused by a spinal leak.

When the brain loses some of its normal buoyant support, sensitive structures may shift or stretch.

This can produce severe headaches and other neurological symptoms.

In some cases, it can also affect memory, concentration, behavior, and cognitive function.

Why a Spinal Fluid Leak Can Look Like Dementia

Most people associate dementia with progressive diseases that damage brain cells over time.

Alzheimer’s disease, for example, involves complex neurodegenerative changes that affect memory and other cognitive functions.

But memory loss does not always mean that a person has Alzheimer’s disease.

There are numerous potentially treatable conditions that can affect thinking and memory.

A spinal CSF leak is one of the less common possibilities.

When fluid loss causes significant brain sagging, the resulting mechanical changes can disrupt the functioning of brain structures involved in cognition, movement, and behavior.

Rarely, patients develop a syndrome sometimes called frontotemporal brain sagging syndrome.

This condition may produce symptoms resembling frontotemporal dementia, including personality changes, impaired judgment, and difficulties with language or executive functioning.

Other patients may primarily experience headaches, dizziness, problems walking, and memory difficulties.

For Roberts, the combination of neurological and cognitive symptoms was so severe that doctors initially suspected a degenerative disorder.

However, the abnormal brain imaging suggested that a different mechanism could be responsible.

And unlike many progressive neurodegenerative diseases, symptoms caused by a spinal fluid leak may improve when the leak is successfully treated.

The Hidden Problem Was in Her Spine — Not Her Brain

Discovering brain sagging was only the beginning.

Doctors still needed to identify exactly where the cerebrospinal fluid was escaping.

To do this, they performed a specialized imaging procedure called a dynamic myelogram.

During myelography, contrast material is introduced into the fluid-filled space surrounding the spinal cord.

Imaging then helps specialists identify abnormalities in the movement or drainage of cerebrospinal fluid.

The investigation revealed a leak on the right side of Roberts’ thoracic spine, in the middle portion of her back.

More specifically, she had an unusual abnormal connection called a CSF-venous fistula.

Normally, cerebrospinal fluid remains within a protective compartment around the central nervous system.

A CSF-venous fistula creates an abnormal pathway that allows spinal fluid to drain into the venous circulation.

These fistulas can be extremely difficult to detect.

They may not produce the obvious collection of leaked fluid that doctors sometimes see with other types of spinal CSF leaks.

As a result, ordinary imaging may miss them.

Specialized techniques and experienced neuroradiologists are often necessary to locate the problem.

For Roberts, identifying the fistula finally provided a coherent explanation for years of unexplained symptoms.

Her First Treatment Worked — But the Relief Didn’t Last

Doctors initially attempted an epidural blood patch.

This procedure involves injecting a patient’s own blood into the epidural space near the spine.

For some types of cerebrospinal fluid leaks, the blood can help seal the opening and allow normal fluid dynamics to recover.

However, Roberts’ leak involved an abnormal connection to a vein.

A blood patch was not sufficient to correct the problem.

In 2021, she traveled to Cedars-Sinai Medical Center in Los Angeles for specialized surgery.

During the operation, surgeons used clips to close the abnormal connection.

The improvement was dramatic.

Roberts regained much of the memory and everyday functioning she had lost.

She was once again able to think clearly and participate in normal activities.

For a woman who had been preparing for the possibility of dementia-related disability, the recovery was life-changing.

Unfortunately, the relief proved temporary.

By 2023, her headaches and memory difficulties had returned.

Doctors discovered another spinal fluid leak.

But this time, a Houston medical team offered an alternative approach.

A Minimally Invasive Procedure Helped Restore Her Life

At Houston Methodist Hospital, neurosurgeon Dr. Kurt Yaeger proposed treating Roberts’ leak using a minimally invasive procedure called endovascular embolization.

Rather than performing another major operation through her back, doctors could approach the abnormal blood vessel from inside the vascular system.

During the procedure, a catheter was inserted through a blood vessel in her groin.

The medical team carefully guided the catheter through the blood vessels until it reached the location of the fistula.

A special embolic substance was then delivered to close the abnormal connection and stop cerebrospinal fluid from draining into the vein.

The procedure required a highly specialized team and precise imaging guidance.

Roberts became the first patient with a spinal CSF leak to undergo this technique with Yaeger’s team at Houston Methodist.

Unlike her previous operation, which required a hospital stay, she was able to return home the same day.

According to her family, the second procedure provided substantial relief.

Her cognitive functioning improved, and she was able to return to the activities she had previously enjoyed.

Her experience also helped Houston Methodist develop a specialized program for treating spinal CSF leaks.

8 Warning Signs of a Spinal Fluid Leak

Spinal cerebrospinal fluid leaks can produce a wide range of symptoms.

Some are relatively characteristic, while others are easily confused with more common medical conditions.

The following signs may warrant further neurological evaluation, particularly when several occur together.

1. Headaches That Get Worse When Standing

One of the classic symptoms of spontaneous intracranial hypotension is an orthostatic headache.

This means the pain becomes worse when sitting or standing and improves after lying down.

However, not every patient experiences this pattern, especially when the condition has been present for a long time.

2. Persistent Neck Pain or Stiffness

Changes in cerebrospinal fluid volume can place tension on pain-sensitive structures, producing neck discomfort or stiffness.

3. Dizziness and Balance Problems

Some patients experience vertigo, unsteadiness, or difficulty walking.

These symptoms may interfere with everyday activities and increase the risk of falls.

4. Ringing in the Ears

Tinnitus, muffled hearing, or a sensation of ear fullness may develop.

These symptoms can occur because changes in cerebrospinal fluid dynamics may influence structures involved in hearing and balance.

5. Unexplained Memory Loss

Although less common than headaches, cognitive problems can occur in certain patients.

These may include short-term memory difficulties, mental fog, and problems concentrating.

6. Personality or Behavioral Changes

Rare cases of severe brain sagging can cause behavioral changes resembling frontotemporal dementia.

Family members may notice unusual behavior, poor judgment, or loss of interest in previously enjoyed activities.

7. Nausea and Sensitivity to Light

Headaches associated with spinal CSF leaks can sometimes resemble migraine, with nausea, light sensitivity, or other overlapping symptoms.

8. Symptoms That Persist Despite Normal Early Tests

Some spinal fluid leaks are difficult to identify using standard imaging.

A normal initial CT scan or MRI does not necessarily exclude the condition.

However, persistent symptoms alone do not establish a diagnosis, and many more common disorders can cause similar complaints.

Why Doctors Sometimes Miss This Condition

Spontaneous spinal CSF leaks are considered uncommon and may be underdiagnosed.

Several factors can make diagnosis difficult.

First, symptoms overlap with conditions such as migraine, vestibular disorders, neck problems, and neurological diseases.

Second, the classic positional headache may become less obvious over time.

Third, some leaks are extremely small or involve abnormal venous drainage that cannot be identified using routine imaging.

Finally, even when an MRI shows abnormalities, the signs may be subtle unless the scan is reviewed by a specialist familiar with intracranial hypotension.

In Roberts’ case, the initial MRI did not reveal an obvious explanation.

It was a later scan, carefully reviewed by a neuroradiologist, that showed the downward displacement of her brain.

The finding shifted attention toward a spinal fluid leak and ultimately led to targeted treatment.

Does Memory Loss Always Mean Alzheimer’s Disease?

No.

Although progressive memory loss can be a warning sign of Alzheimer’s disease or another neurodegenerative condition, cognitive problems have many possible causes.

Some are potentially reversible or manageable.

Examples include:

  • Vitamin B12 deficiency
  • Thyroid disorders
  • Medication side effects
  • Sleep apnea and chronic sleep deprivation
  • Depression
  • Certain infections or inflammatory disorders
  • Normal-pressure hydrocephalus
  • Metabolic disturbances
  • Rare neurological conditions, including spinal CSF leaks

Identifying the cause requires a comprehensive medical evaluation.

Doctors may consider laboratory testing, medication review, cognitive assessment, neurological examination, and imaging depending on the patient’s symptoms.

Importantly, most cases of memory loss are not caused by spinal fluid leaks.

Roberts’ condition was unusual, and her experience should not lead people to assume that dementia symptoms generally indicate intracranial hypotension.

Nevertheless, her story demonstrates why an accurate diagnosis matters.

When Should Someone Seek Medical Attention?

New or worsening memory loss should be discussed with a healthcare professional, particularly when it interferes with work, relationships, or daily responsibilities.

Medical evaluation is especially important when cognitive symptoms occur alongside severe headaches, balance difficulties, neurological changes, or unusual symptoms that have not been adequately explained.

A sudden severe headache, acute confusion, new weakness, seizures, or difficulty speaking requires emergency medical attention.

For patients with persistent headaches that worsen when upright and improve while lying down, clinicians may consider whether a spinal CSF leak is one of the possible causes.

Specialized investigation should be guided by a qualified medical team rather than self-diagnosis.

The Bigger Medical Lesson: Sometimes the Brain Isn’t the Original Problem

Debra Roberts spent years fearing that her mind was deteriorating.

Her memory problems became so serious that she stopped working, struggled to recall important family events, and faced the possibility of long-term nursing care.

Yet the underlying cause was not the progressive dementia doctors initially suspected.

A rare connection between the spinal fluid space and a vein was draining the fluid that normally supports her brain.

Once specialists identified and treated the problem, her symptoms improved significantly.

Her case highlights the importance of recognizing that neurological symptoms can originate from unexpected parts of the body.

A problem in the spine can sometimes affect brain position and cognitive function.

And a diagnosis that initially appears irreversible may occasionally have a treatable explanation.

The Bottom Line

For years, a Texas woman believed she was developing dementia.

Then a doctor noticed an unusual finding on a brain scan: her brain appeared to be sagging downward because of a spinal cerebrospinal fluid leak.

Specialized testing identified a rare CSF-venous fistula, and targeted treatment helped restore her memory and quality of life.

The case is an important reminder that memory loss is a symptom, not a diagnosis.

Although Alzheimer’s disease and other forms of dementia are serious and common causes of cognitive decline, some conditions that resemble dementia may be treatable.

Recognizing unusual symptoms, carefully reviewing medical evidence, and considering appropriate alternative diagnoses can sometimes make an extraordinary difference.
