Imagine living with a constant, invisible torment that doctors often struggle to understand. For individuals with sickle cell disease, this is a daily reality, and the traditional methods of assessing pain often fall short. But a groundbreaking study offers a new perspective, using innovative technology to decode the language of pain within the brain.
This research, spearheaded by Carnegie Mellon University's Wood Neuro Research Group, moves beyond simple pain scales to provide a more comprehensive understanding of the patient's experience. Using advanced brain imaging and a digital visualization tool, they aim to bridge the communication gap between patients and clinicians.
"Traditional questionnaires only scratch the surface," explains Joel Disu, the lead author of the study published in The Journal of Pain. "They fail to capture the complexity of sickle cell pain. We wanted to see what happens in the brain when people describe their pain in a way that's true to how they actually feel it."
The team explored the potential of Painimation, a novel app developed by Dr. Charles Jonassaint at Emory University. This app allows patients to describe their pain using animated visuals, such as throbbing, stabbing, or cramping sensations, instead of relying on a numerical scale.
By analyzing ultra-high-resolution MRI data from 27 sickle cell patients and 30 pain-free participants, researchers compared brain connectivity patterns. They focused on three key brain networks associated with pain perception: the default mode, salience, and somatosensory networks. The results revealed significantly reduced connectivity in all three networks among sickle cell patients, particularly in regions linked to emotion, attention, and sensory processing.
And this is the part most people miss... When the team correlated these imaging findings with the patients' Painimation selections, a clear pattern emerged. Pain descriptors like cramping and stabbing correlated strongly with changes in the somatosensory network, the area responsible for processing physical sensations. Moreover, patients who reported more intense sensations showed even greater disruption in these brain regions.
"This is a foundational step toward developing objective pain biomarkers," Disu explains. "We can begin to see, in real time, how the quality and intensity of pain map onto the brain."
But here's where it gets controversial... The study also highlights a critical issue in healthcare: the frequent misunderstanding of pain in sickle cell disease, which can lead to mistrust between patients and providers. Many patients avoid seeking medical help due to fear of being dismissed or labeled as drug-seeking.
"Our work helps visualize what has long been invisible or ignored," notes Sossena Wood, an assistant professor of biomedical engineering at Carnegie Mellon. "This research validates patients' experiences with neuroscientific evidence. It shows that the pain they feel is real, measurable, and rooted in brain function."
The implications of this research extend beyond the lab. Painimation is already being adopted by several sickle cell communities, assisting clinicians in better interpreting pain experiences. Wood's team is exploring how virtual reality and wearable sensors might one day help modulate or even reduce pain through targeted brain stimulation.
Adding to the accolades, Joel Disu was selected by the American Society of Hematology to receive the 2025 Hematology Inclusion Pathway Graduate Student Award, which includes a $40,000 annual stipend over two years. This support will aid his ongoing research, aiming to transform how pain is understood and managed in sickle cell disease.
Wood emphasizes, "Ultimately, we want to bridge the gap between patients' lived experiences and what clinicians can measure. By bringing together neuroscience and empathy, we can start to transform the way pain is understood and treated in sickle cell disease."
