PITTSBURGH – For some patients with Chiari Malformation type 1 (CM1), a skull abnormality where the brain pushes down into the skull base, brain surgery may unexpectedly correct early cognitive decline and symptoms of depression and anxiety, University of Pittsburgh neurosurgeons reported Feb. 21, 2025, in the Journal of Neurosurgery. This groundbreaking research highlights a previously unrecognized link between a structural skull abnormality and notable cognitive and psychiatric symptoms.
In individuals with CM1, surgical intervention may alleviate classic symptoms like headaches and tingling sensations in the hands and feet, but also improve memory and psychological well-being. The study underscores the importance of considering cognitive and psychiatric symptoms in the diagnosis and treatment of CM1.
Many clinicians don’t recognize cognitive and psychiatric symptoms as components of a Chiari diagnosis,said senior author Robert Friedlander, M.D., chair of neurological surgery at Pitt and co-director of the UPMC Neurological Institute.Our study makes it clear that those symptoms should not be ignored and that there is a population of patients who might see significant advancement in symptoms after surgery.
Patients with CM1 often undergo surgery to reduce pressure on the cerebellum. This minimally invasive procedure, typically completed within two hours, widens the skull base and repositions the cerebellum to improve cerebrospinal fluid flow and relieve pressure on the brainstem and spinal cord.
According to a previous study using brain imaging, nearly 1% of Americans have a structural CM1 malformation.While many are asymptomatic, some experience severe headaches, especially when coughing or sneezing, or tingling in their arms and legs. Many also report mental health symptoms that are frequently dismissed.
Many of the Chiari patients I see in my clinic complain of brain fog. I would hear of similar symptoms so often that I took notice,said Friedlander.An or else healthy individual between 16 and 40 years of age should not be experiencing cognitive decline.After surgery many patients happily informed me that they felt cognitively improved.
To objectively measure these improvements, a team of neuropsychologists, led by Luke Henry, Ph.D.,assistant professor of neurosurgery at Pitt,conducted thorough assessments. Their findings, integrated with the surgical outcomes, provided compelling evidence supporting the link between CM1, surgery, and improved cognitive and mental health.
this research suggests that early intervention through surgery may considerably improve the quality of life for patients experiencing these often-overlooked complications.
Cerebellar Surgery: Improving Cognitive Function and Psychiatric Symptoms in CM1 Patients
A University of Pittsburgh Medical Center (UPMC) study from 2015 to 2023 evaluated 54 CM1 patients, assessing their psychiatric symptoms and cognitive performance before and six months after surgery. The comprehensive neuropsychological evaluations included measurements of processing speed, attention, memory, and executive function, along with assessments of anxiety and depression symptoms.
Nearly 90% of participants experienced improvements in either their cognitive function or psychiatric symptoms, with approximately one-third showing improvements in both areas. This suggests a significant positive correlation between the surgery and alleviation of both cognitive and mental health challenges.
“Our results show that the surgery alleviates much of the psychiatric distress related to physical symptoms and improves the cognitive problems that the patients present with prior to the intervention,”henry said.“these observations help us better understand the manifestations of the cognitive dysfunction in these patients and show that a ‘fog,’ as patients often describe it, can be lifted.”
While further research is needed, the study strongly suggests a crucial role for the cerebellum in cognitive and psychiatric dysfunction. The researchers highlight the potential for cerebellar surgery to significantly impact the lives of CM1 patients struggling with these debilitating symptoms. The study’s authors include Luke Henry, Ph.D., Michael McDowell, M.D., Amy Byrd, Ph.D., Ricardo Fernández-de Thomas, M.D., Yue-fang Chang, Ph.D., and Kamil Nowicki, M.D.

Headline: Unlocking the Mysteries of the Brain: How Chiari Malformation Surgery Enhances Cognitive and Mental Health
Opening:
Did you know that a simple surgical intervention could be the key to unlocking diminished cognitive abilities and improving mental health in individuals with a structural brain malformation? This surprising revelation from scientific research offers new hope for patients suffering from Chiari malformation type 1 (CM1).
Interview:
Senior Editor: Introduction to the groundbreaking study at the University of Pittsburgh, this research suggests a noteworthy link between brain surgery and alleviation of cognitive decline and mental health issues in CM1 patients. Could you explain the potential mechanisms behind this unexpected benefit?
Expert: Absolutely, the journey to uncovering these benefits began with recognizing that Chiari Malformation type 1 (CM1) wasn’t merely about physical symptoms like headaches or tingling. Researchers, including Dr. Robert Friedlander and Dr. Luke Henry, discovered that when the cerebellum is abnormal in shape and position, it can impact cerebrospinal fluid flow, causing a shift that affects brain regions responsible for cognition and mood regulation.
By surgically widening the skull base and repositioning the cerebellum, surgeons can alleviate this pressure, perhaps restoring more natural fluid dynamics. This alleviation can lead to improvements in neural communication, ultimately enhancing cognitive functions and emotional stability.
Senior Editor: It’s fascinating how cognitive symptoms often whent unrecognized in these patients. how does this study change the way we approach diagnosing and treating CM1?
Expert: This research emphasizes a much-needed paradigm shift in diagnosing CM1. Traditionally, the focus was purely on physical symptoms, but it’s become increasingly clear that cognitive and mental health symptoms are highly relevant and should not be ignored. The study highlights an imperative to adopt a more holistic approach, including thorough neurological and psychological evaluations, when diagnosing and treating CM1.
This broader perspective enriches our understanding of patient experiences, ensuring treatments are more comprehensive and tailored, leading to significantly improved quality of life.
Senior Editor: the study reported improvements in both cognitive function and psychiatric symptoms in post-surgical patients. Could you provide real-world examples illustrating these improvements?
Expert: Absolutely. Let’s consider the case of a young adult, previously performing well at academic and professional levels, who begins experiencing brain fog, memory lapses, and persistent frustrations that resemble depression. Post-surgery, this individual regains their former cognitive sharpness and mental clarity, which drastically improves their life trajectory—resume active sports or hobbies, succeed academically, and maintain healthier social interactions.
Such recovery stories are integral to understanding how CM1 surgery can dramatically shift lives and open opportunities previously masked by untreated symptoms.
Senior Editor: With nearly one-third of patients showing improvements in both cognitive and psychiatric areas, what does this imply for future research directions?
expert: The compelling results serve as a foundation for future research to further unravel the cerebellum’s role in cognitive and psychiatric health. Longitudinal studies are vital to observe lasting impacts and potential for even broader applications. Moreover, exploring non-surgical interventions or complementary therapies could further enhance post-surgical outcomes and enrich treatment paradigms.
Senior editor: What are the key takeaways for medical professionals and patients from this study?
Expert: Key takeaways:
- Holistic Diagnosis: Recognize cognitive and psychiatric symptoms as key indicators of CM1, ensuring a comprehensive diagnostic process.
- Patient-Centered Treatment: Embrace a treatment approach that balances physical relief with cognitive and psychiatric assessments.
- research Continuation: Encourage ongoing research to deepen understanding and explore new treatment possibilities.
