Leila Nabulsi, PhD, a dedicated postdoctoral researcher specializing in computational neuroscience at the Keck School of Medicine of USC, is embarking on an exciting new research initiative focused on bipolar disorder. She has secured the prestigious 2025 NARSAD Young Investigator Grant from the Brain & Behavior Research Foundation, a significant milestone aimed at providing early-career researchers with essential funding to explore innovative paths in mental health study.
Bipolar disorder is marked by its defining characteristic of fluctuating episodes of extreme highs and lows in mood. Current neuroimaging research has traced its origins to the limbic system—a complex array of brain structures deeply involved in managing emotional responses and cognitive functions—and its intricate connections with other crucial brain areas.
The newly awarded grant, which offers a generous $70,000 for 2025, will enable Nabulsi to broaden her ongoing research program, which has already begun identifying the specific locations and mechanisms through which bipolar disorder interferes with normal brain function. Her innovative project will employ advanced analytical techniques alongside the collaborative efforts of the Enhancing Neuro Imaging Genetics Through Meta Analysis (ENIGMA) consortium, which aggregates researchers and comprehensive imaging data from across the globe, allowing for more robust and varied samples essential for scientific exploration.
“We’re working to build a database of bipolar disorder-specific brain changes, which may ultimately improve both diagnosis and treatment of the condition,” Nabulsi emphasized, pointing to the potential impact of her work on current psychiatric practices.
Disentangling medication effects
Most neuroimaging studies of bipolar disorder have looked at small, primarily Caucasian samples, which limits the generalizability of the findings in broader, more diverse populations. Moreover, a significant drawback of current research is the confounding impacts of various medications on brain imaging results.
“Individuals with bipolar disorder are typically prescribed a range of medications over their lifetime, including at the time of brain scan collection, making it challenging to determine which brain changes stem from the medications and which arise from the disorder itself,” Nabulsi explained, highlighting a critical hurdle in understanding the illness.
However, the utilization of the ENIGMA bipolar disorder dataset, comprising brain MRI scans collected by over 200 research groups globally, provides a large and diverse pool of data. This wealth of information is instrumental in discerning the distinctions between medication effects and the intrinsic characteristics of the disorder. Nabulsi and her team are meticulously analyzing medication type, dosage, and duration data from more than 3,700 participants.
“With the ENIGMA bipolar disorder sample, we can start to disentangle the effects of medication from the underlying brain changes associated with the disorder itself,” she said.
Pinpointing changes in the brain
The funding will facilitate a more in-depth exploration of alterations in white matter—the neural pathways that connect various brain regions—by contrasting individuals diagnosed with bipolar disorder against those without the condition. Preliminary findings indicate she is already mapping these pathways with exceptional precision, discovering microstructural variations in white matter that link the limbic system to the basal ganglia. This significant discovery corroborates that structural transformations in bipolar disorder are anatomically associated with critical areas of the brain responsible for regulating mood and emotional processing.
A revolutionary technique called bundle analytics, or BUAN, is providing researchers with unprecedented capabilities to scrutinize white matter. BUAN enables Nabulsi to meticulously analyze brain scans and virtually navigate along brain pathways. This method fosters the ability to compare pooled data from bipolar disorder patients to those without the condition, pinpointing specific areas along these pathways where connectivity issues arise.
“We can map, along the tract, exactly where connectivity changes occur in bipolar disorder. That’s a very advanced way of looking at microstructural alterations in the brain,” Nabulsi articulated, reflecting the sophistication of her research methodology.
Advanced statistical methodologies, notably the application of graph theory, are also enhancing the research efforts. This mathematical framework models the organization of the intricate networks within the brain’s white matter. By employing graph theory, Nabulsi is examining the disparities in brain network organization between individuals with and without bipolar disorder, as well as assessing the efficiency of neural information traversal across these networks.
Through these innovative methods and the comprehensive ENIGMA bipolar disorder dataset, Nabulsi endeavors to elucidate how symptom severity in bipolar disorder—such as the frequency of manic or depressive episodes—correlates with observable changes in brain structure. Additionally, she is investigating how various medication factors—encompassing type, dosage, and duration—connect to alterations in white matter integrity.
Ultimately, creating an extensive understanding of brain changes associated with bipolar disorder could enhance scientific knowledge about the intricate circuitry of the brain, the nature of symptom progression, and the efficacy of various treatment approaches. Such insights may lead to the identification of new biomarkers, paving the way for more precisely targeted interventions and tailored treatment strategies.
“Right now, diagnosis and treatment of bipolar disorder is largely reliant on psychiatric evaluation and trial-and-error to determine effective medication. We hope this work could one day facilitate the identification of biologically-grounded approaches for treatment,” Nabulsi concluded, expressing hope for a future where such methods can revolutionize patient care.

Neurocircuitry in Bipolar Disorder: The Ambitious Quest of Dr. Leila Nabulsi
Hello, dear readers! Today, we’re diving into the fascinating—and *frankly* downright intriguing—world of bipolar disorder research, led by the talented Dr. Leila Nabulsi. Yes, I know what you’re thinking: “Neurocircuitry? Sounds like something you’d hear in a sci-fi film!” But fear not! This is a thrilling ride through the brain’s complex wiring that even your snoozing uncle would find riveting. Or at least, we hope.
Dr. Nabulsi is a postdoctoral researcher at the Keck School of Medicine, and she has just snagged herself a shiny $70,000 NARSAD Young Investigator Grant for 2025—because apparently, just having a PhD isn’t quite enough to impress researchers these days. This grant isn’t some participation trophy; it’s a highly competitive ticket to dive deeper into understanding the neurocircuitry that underlies bipolar disorder. And by “dive deeper,” I mean she’s going to unearth the inner workings of our brains like a high-tech Indiana Jones.
Bipolar Disorder: The Mood Rollercoaster
Now, let’s break it down. Bipolar disorder is characterized by its infamous mood swings, swinging from high-energy mania to gut-wrenching despair. Essentially, it’s like being on a really unpredictable rollercoaster—without the thrill of cotton candy! Current neuroimaging research has pinpointed the limbic system as the stage where this tumultuous show takes place, a group of deep-brain structures that manage our emotions, thoughts, and a reasonable facsimile of decision-making (which most of us can certainly appreciate right now!).
So, what does Dr. Nabulsi plan to do with this grant? Well, she’s set her sights on creating a comprehensive database of brain changes specific to bipolar disorder. Why? Because let’s face it—diagnosing and treating this condition often feels like playing roulette in a casino. “Do we go with this medication or that one? Spin again!” The hope here is that with better mapping of brain changes, the process could ultimately improve both diagnosis and treatment. Imagine a world where your doctor doesn’t have to guess what might work for you, but rather can actually check the map and say, “Ah! Here it is! The very potion to restore your sanity!”
Decoding the Enigma: Medication Effects
Let’s talk about medication. It’s a complex game with a pack of cards as diverse as my last Tinder date’s interests. Most previous research focused on small, largely *Caucasian* samples. According to Dr. Nabulsi, this means it’s been tricky to generalize results to people from all walks of life or cultural backgrounds. What’s worse is that the effects of the medications themselves have been muddling the waters more than a 3 a.m. trip to a kebab shop after a night out. “Which brain changes are due to the disorder? And which are due to the pills?” It’s like playing detective in a world overflowing with misleading clues.
However, the ENIGMA dataset, with its rich kaleidoscope of brain MRI scans compiled by over 200 research groups, gives Nabulsi the chance to glean real insight into these perturbing puzzles. With over 3,700 participants in the mix, she’s ready to sift through that jumble of data, separating signal from noise. “With the ENIGMA bipolar disorder sample, we can disentangle medication effects from the disorder itself!” she confidently proclaims—as if she’s about to turn water into wine.
White Matter and the Fine Art of Mapping
But wait! There’s more! Dr. Nabulsi is also rolling up her sleeves to analyze changes in white matter, the part of the brain that connects everything, kind of like a very overworked Uber driver. Thanks to a cutting-edge technique known as bundle analytics (BUAN), Nabulsi can examine brain scans and virtually traverse these neural highways. Imagine road-tripping through your brain whilst comparing routes with and without bipolar disorder—often paved with potholes of disconnection.
Using this fancy technology, she’s mapping microstructural changes that link the limbic system to the basal ganglia, confirming that structural changes are linked to those regions that control mood, motivation, and emotional processing. What does that mean? It’s like she’s assembling the ultimate Google Map of emotional journeys inside our heads—making sure we know whether to navigate through sunny beaches or stormy seas!
The Future of Bipolar Disorder Treatment
In the end, Dr. Nabulsi’s groundbreaking work could redefine how we understand brain circuitry, symptom progression, and treatment for bipolar disorder. She’s not just collecting data; she’s on a quest to uncover new biomarkers that could lead to targeted interventions and personalized treatment strategies. Imagine walking into a doctor’s office and having the doctor say, “Your brain says you need this treatment, no guessing involved!” It would be the medical equivalent of a chef whipping up the perfect soufflé while you wait.
In conclusion, while bipolar disorder presents many uncertainties, researchers like Dr. Nabulsi are lighting up the path forward with advanced techniques and precise methodologies. Let’s hope this research will yield not just answers, but a more scientifically grounded approach to treatment—one that makes guessing games a relic of the past. If anyone can put the logic back into the chaotic world of emotions, it’s her. And we’re here for it!
Stay tuned for more updates, and don’t forget to keep your minds open—never stop exploring the fabulous inner workings of your brains!
