Study Finds Space Travel Alters Astronauts’ Brain Structure

On Monday, Jan. 12, findings published in the journal Proceedings of the National Academy of Sciences (PNAS) revealed that “the brain shifts upward and backward within the skull following spaceflight, with sensory and motor regions exhibiting the largest shifts.”

The study explained that, “Understanding how spaceflight impacts the human brain is crucial as space exploration and tourism expand.”

Researchers “evaluated brain regional shift magnitudes and deformations and their behavioral correlates,” analyzing MRI data from 26 astronauts and 24 participants from “a long-duration head-down tilt bed rest study.”

An abstract read, “We aligned skull position across timepoints (before and after spaceflight or bed rest) as a reference and then used rigid body registration to quantify brain position change.” 

“The brain shifted backward, upward and rotated back in the pitch direction from before to after spaceflight and bed rest in a fashion that correlated with exposure duration,” it added.

The study found that “widespread recovery occurred in all three dimensions (particularly in the up–down direction) over [6 months] following spaceflight.” However, it also noted, “Although most of the brain deformation recovered over [6 months] post-flight, some persisted.”

Studies like this could prove to be crucial given the direction space travel is heading in. In 2022, PEOPLE reported that a NASA official had said it was only a matter of time before people will be living — and working — on the surface of the moon.

Rachael Seidler — one of the study’s co-authors and a professor in the department of applied physiology and kinesiology at the University of Florida — said, “We need to understand these changes and their impacts to keep astronauts safe and healthy and protect their longevity,” per NBC News.

The outlet noted that a few individuals studied had spent extended, yearlong stints aboard the International Space Station, while the standard duration for a mission is around six months.

“The people who went for a year showed the largest changes,” Seidler said, per NBC News. “There were still some changes evident in people who went for two weeks, but duration seems to be the driving factor.”

She added to the outlet that the upward movement in the brain among astronauts who had stayed in space for six months or longer had been “pretty extensive,” especially in structures at the top of the organ.

“It’s on the order of a couple of millimeters,” Seidler said, adding, “Which doesn’t sound like a big number, but when you’re talking about brain movement, it really is. That kind of change is visible by eye,” according to the outlet.

She explained that the changes in the brain would sometimes cause “sensory conflicts” while the astronauts were in space. These symptoms would often manifest as temporary disorientation or motion sickness in space, while the shifts would contribute to things like balance issues when back on Earth, NBC News noted.

Seidler told the outlet that it “was surprising” to her that the study didn’t find that astronauts suffered serious symptoms, such as cognitive impairment or headaches, during or after spaceflight.

While speaking further about the study, Seidler added to PEOPLE, “We already knew that the brain shifts upward within the skull from pre-to post-flight. BUT, we were looking at the brain as a whole on average (imagine like a basketball). Here, we are looking at individual brain structures (imagine like a head of broccoli with individual florets that can move separately).” 

“When we do this, we see that the individual structures move more than we thought they did (a couple of [millimeters], which doesn’t sound like much, but it is a lot for the brain and it’s visible by eye). And, the left and right side move towards each other at the top of the brain, and away from each other at the bottom of the brain. This deforms the brain tissue,” she added. “Surprisingly, there are not major symptoms, but these are highly trained and resilient individuals.”

The latest study is one of many published regarding space and health. However, despite scientists already knowing that spaceflight can affect the brain, Seidler’s study is among the first to reveal how the changes affect how astronauts function in space and back on Earth, NBC News reported, citing Dr. Mark Rosenberg.

Rosenberg — the Director of the Aerospace and Performance Neurology program and Assistant Professor of Neurology at the Medical University of South Carolina — said of the study, which he was not involved with, “We knew the brain shifts upward, but does it actually have any kind of operational impact?” per NBC News.

“This study is able to make some of those associations,” he added to the outlet.

Rosenberg told the publication that there are still certain questions that need to be answered as more people plan to head to space.

“If you’ve been on Mars with one-third Earth’s gravity, or on the moon with one-sixth Earth’s gravity, will it take three or six times as long to get back to normal?” he said, per NBC News.

“Whether we care to admit it or not, we are eventually going to become a space-faring species,” Rosenberg told the outlet. “It’s only a matter of time. And these are just some of the unanswered questions that we need to sort out.”

NMC Royal Hospital, Mohammed Bin Zayed City, Successfully Treats Lifelong Complications from Childhood Surgery

Advanced Reconstructive Surgery Helps Patient Regain Normal Urinary Function After Years of Complications

Abu Dhabi, UAE – A specialist urology team at NMC Royal Hospital, Mohammed Bin Zayed City, led by Dr. Rami Labib, Urologist, has successfully helped a 30-year-old patient regain normal urinary function after years of complications linked to a surgery he underwent as a child.

For many years, the patient experienced difficulty urinating and persistent urine leakage through small openings along the penis. The condition significantly affected his daily life, causing discomfort, embarrassment and a loss of confidence.

The complications were related to hypospadias, a condition present at birth in which the opening of the urethra is not located at the tip of the penis. While hypospadias is commonly corrected during childhood and most patients achieve excellent long-term results, a small number may develop complications later in life that require further treatment.

After a detailed assessment, Dr. Labib identified narrowing of the urethra, known as a urethral stricture, along with abnormal passages that were causing urinary leakage. Imaging tests confirmed the diagnosis and helped the team plan the most appropriate treatment.

To restore normal function, Dr. Labib performed a highly specialised reconstructive procedure known as a buccal mucosal graft urethroplasty. The surgery used a small piece of tissue taken from the inside of the patient’s cheek to rebuild the damaged section of the urethra and close the abnormal openings responsible for the leakage.

Commenting on the case, Dr. Rami Labib said:

“Patients who experience complications years after hypospadias repair often face significant physical and emotional challenges. Every case is different and requires careful planning to achieve the best outcome. Modern reconstructive techniques allow us to restore normal urinary function and help patients return to their daily lives with greater comfort and confidence.”

The operation was completed successfully, and the patient made a good recovery. During follow-up visits, he reported being able to urinate normally without any leakage and described a substantial improvement in his overall quality of life.

Expressing his gratitude, the patient said:

“After years of struggling with urinary problems following multiple surgeries, I can finally urinate normally again without any leakage. I am extremely grateful to Dr. Rami and the entire medical team for restoring my confidence and giving me my life back.”

Dr. Labib noted that advances in reconstructive urology continue to improve outcomes for patients with even the most complex conditions. With expert assessment, personalised treatment plans, and modern surgical techniques, many patients can achieve long-lasting relief and return to everyday activities with confidence.

Fakeeh University Hospital Brings New Hope to Patients with Complex Brain Conditions Through Advanced MRI-Guided Laser Neurosurgery

Russian teenager with high-risk brainstem tumour successfully undergoes minimally invasive laser treatment in Dubai

Dubai, UAE – June 2026 – Fakeeh University Hospital has successfully performed an advanced MRI-guided Laser Interstitial Thermal Therapy (LITT) procedure on a 15-year-old patient from Russia suffering from a brainstem glioma, one of the most challenging and high-risk brain tumours encountered in neurosurgery.

The young patient travelled to Dubai after conventional oncology treatments failed to halt the progression of the disease. The tumour, located deep within the brainstem, had caused progressive neurological deterioration, including worsening motor deficits and paralysis, significantly affecting his quality of life and presenting a complex therapeutic challenge.

Following extensive multidisciplinary discussions involving neurosurgery, neuro-oncology, radiology, and rehabilitation specialists, the medical team at Fakeeh University Hospital carefully evaluated all available treatment options. Given the tumour’s location within one of the most delicate regions of the brain, traditional open surgery was associated with exceptionally high risks.

The brainstem controls many of the body’s most vital functions, including movement, breathing, heart rate, and consciousness. Surgical intervention in this area has historically carried substantial risks, including permanent paralysis, respiratory failure, and even cardiac arrest.

To minimize these risks while offering a potential treatment option, the team elected to perform MRI-guided Laser Interstitial Thermal Therapy (LITT), a highly advanced minimally invasive neurosurgical technique increasingly used worldwide for carefully selected patients with deep-seated brain lesions.

The procedure was led by Dr. Tommaso Tufo, Consultant Neurosurgeon – Brain and Spine Surgery at Fakeeh University Hospital, using a stereotactic robotic-assisted approach. Through a small skin incision measuring only a few millimetres, a laser fibre was precisely implanted into the target area using advanced robotic guidance and neuronavigation technology.

The implantation phase lasted just over one hour, after which the patient was transferred to the MRI suite. Under continuous real-time MRI monitoring, laser thermal therapy was delivered over the course of approximately one to two hours, allowing surgeons to visualize the thermal effect in real time and precisely control the treatment zone throughout the procedure.

One of the most significant advantages of MRI-guided laser therapy is its ability to reach deep and difficult-to-access areas of the brain while minimizing disruption to surrounding healthy tissue. Real-time MRI thermal mapping provides exceptional precision, allowing surgeons to perform controlled volumetric reduction of tumours without the need for extensive surgical exposure.

Commenting on the case, Dr. Tommaso Tufo said:

“Brainstem tumours represent some of the most challenging conditions in neurosurgery because of their location within structures that control critical neurological and physiological functions. In this particular case, conventional treatment options had become limited, and traditional open surgery carried considerable risks. MRI-guided laser therapy allowed us to reach the lesion through a minimally invasive approach while maintaining a very high degree of precision and safety.”

He added:

“The successful treatment of this patient demonstrates the potential of modern laser neurosurgery to expand therapeutic options for carefully selected patients who may previously have had very limited alternatives. However, the true significance of this technology extends far beyond a single case.”

While the patient continues to undergo physiotherapy and additional oncological treatment as part of his ongoing care, he tolerated the procedure well and was able to resume mobility following treatment.

Dr. Tufo emphasized that MRI-guided Laser Interstitial Thermal Therapy should be viewed within the broader context of modern neurosurgery rather than as a solution limited to rare brainstem tumours.

“Laser neurosurgery represents an important advancement in the treatment of selected brain tumours, drug-resistant epilepsy, radiation necrosis, and other complex intracranial conditions,” he explained. “The technology allows us to treat lesions located deep within the brain through a very small incision while minimizing trauma to surrounding tissue. Both adult and pediatric patients may benefit from this approach when conventional surgery presents excessive risk.”

Historically, many patients with drug-resistant epilepsy required open cranial surgery to access and remove seizure-causing areas of the brain. Today, in selected cases, MRI-guided laser ablation offers a less invasive alternative that combines precision, safety, and shorter recovery times.

For appropriately selected patients, the minimally invasive nature of the procedure may significantly reduce hospitalization and recovery periods, with some individuals able to return home on the same day or within 24 hours. More complex cases, particularly those involving critical brain structures, may require extended monitoring to ensure optimal neurological recovery.

The introduction of advanced MRI-guided laser neurosurgery further strengthens Fakeeh University Hospital’s position as a regional center of excellence for complex neurological and neurosurgical care. By combining advanced imaging, robotic guidance, and minimally invasive techniques, the hospital continues to expand access to innovative treatment options for patients facing some of the most challenging brain conditions.
