After 31 years of battling treatment-resistant depression, a 44-year-old man found hope through PACE, a new personalized brain stimulation therapy. Using precision brain mapping, researchers tailored stimulation to his unique patterns, leading to a surge of overwhelming joy and long-term improvements that lasted over 30 months, offering a glimpse of lasting wellness
According to a recent preprint study on OSF, a 44-year-old man โwho struggled with severe depression for 31 years, experienced a remarkable turnaround after undergoing PACE (Personalized Adaptive Cortical Electro-Stimulation).โ
For more than three decades, the patient โlived with the persistent weight of treatment-resistant depression, alongside PTSD and panic disorder.โ His psychiatric issues began in childhood: โthe first signs of psychiatric issues appearing when he was just a kindergartner.โ
The study describes how he endured โnumerous hospitalizations, psychiatric evaluations, and multiple rounds of therapy.โ Over the years, he tried โat least 19 differentโ medications and underwent โthree rounds of electroconvulsive therapy (ECT), none of which provided lasting relief.โ His history also included โperiods of extreme hopelessness, including suicidal ideation and attempts.โ
Personalized Brain Stimulation
The new treatment, called PACEโPersonalized Adaptive Cortical Electro-Stimulationโwas designed to tailor stimulation to each patientโs brain. Researchers explained that the process used โprecision functional mapping, which uses functional magnetic resonance imaging (fMRI),โ to create a โbrainotypeโ specific to this individual.
This mapping โhelped the team identify specific areas of the brain to target, ensuring that the treatment was as effective as possible for his unique neurological patterns.โ Unlike generalized approaches, โthe stimulation could now be adjusted in real time, based on the patientโs immediate responses.โ

An Abnormal Finding
The study noted that โthe patientโs salience network was highly atypical.โ The salience network, which helps the brain โidentify and respond to important environmental signals,โ was unusually enlarged in this case. It โcovered 12.4% of the cortical surface area, which is four times more than is typically seen in healthy individuals.โ
This enlargement โis linked to depressionโ and became a key factor in planning the stimulation targets.
A Life-Changing Breakthrough
The results of the stimulation were immediate. After electrodes were implanted, the patient experienced a dramatic shift: โThe first time the default mode network (DMN) was targeted, the patient felt an overwhelming surge of joyโa sensation he described as โso weird to feel.โโ
In his own words, โIt feels nice. So weird to feel. It is so emotional.โ The moment left him in tears and was described as โa powerful testament to the intensity of his feelings.โ

Why PACE Is Different
The researchers stressed that PACE differs fundamentally from conventional methods like ECT. The study explained: โTraditional ECT tends to be more generalized, applying a one-size-fits-all approach to brain stimulation. However, PACEโs design is fundamentally differentโit tailors the stimulation to the specific needs and brain activity patterns of each patient.โ
As the authors noted, โPACE provided [the patient] with the longest stretch of wellness he had experienced in his adult life.โ
Long-Term Improvements
The improvements were not short-lived. Within seven weeks, โthe patientโs suicidal thoughts had completely dissipated.โ After four months, his mood โimproved by 59% on standardized depression scales.โ
Most importantly, these benefits lasted: โthese improvements were sustained over a period of at least 30 months.โ The study concluded that this โoffered the patient a glimpse of a life free from the oppressive grip of depression.
