Imagine focusing on one thing so well that you can control its movement. Now, imagine mentally selecting colors and shapes to create an abstract image – a brain painting. USF computer scientist Marvin Andujar is harnessing the power of concentration and art to develop a new brain-computer interface (BCI) prototype and help study participants use their brain like never before. The goal is to introduce a novel treatment option for individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) by tapping directly into their brain activity.

“This type of brain-computer interaction is more of a brain exercise to improve your attention,” Andujar said. “We’re trying to see how we can narrow that focus over time.”

Similar to Andujar’s previous work with brain-controlled drones, participants’ complete attention is required. To fly forward, a user must focus on a specific movement, such as walking. Individuals from the ADHD community approached Andujar after learning how the brain-controlled drone project harnessed attention span and asked for a device they could use at home.

“That’s why we started working on making brain painting into a tool where those with ADHD can train their attention while doing something creative,” Andujar said.

Andujar just wrapped up a two-year pilot study funded by the National Science Foundation. He and his students collected data from participants who are mainly college students with ADHD who need additional help to focus throughout the semester and pass exams. The most common treatment prescribed is Adderall – a medication known to disturb eating and sleeping patterns.

“In the world of technology, with phone and social media, it’s easy to get distracted,” Andujar said. “The idea of BCIs is similar to meditation practices because the mind is required to focus.”

Improvements are measured by how long one can hold their attention without letting their minds wander. With brain painting, users wear a BCI and focus on screen options and interact with blinking controls to paint on a blank canvas.

BCIs are pathway devices that read electrical brain signals to facilitate interaction with external objects, such as a prosthetic limb or drone. With Andujar’s BCI brain painting method, participants wear a device lined with sensors and choose from a limited selection of colors, shapes or controls by focusing on one at a time. A blinking light lets the user know when their selection is recognized. This feedback causes a stimulus spike in the parietal lobe (the part of the brain responsible for sensory perception and integration) and is detected by the sensors. These spikes are then classified by an algorithm and saved on project hard drive as a user profile.

“Everyone’s brain activity is unique, so each participant has to train the system to detect their decision making. Accuracy and speed improve the more it’s done,” Andujar said.

Brain painting is a BCI method first used to help ALS patients create art. Andujar modified this method to implement two versions – a 2D and virtual reality (VR) version. In the VR experience, participants can fully immerse themselves within the environment while painting. The hope is this work will also help those struggling with mental health.

“Art has shown to elicit positive emotions, so with the VR version, we are asking how will concentration and emotion improve when also being immersed inside your own painting?” Andujar said.

Andujar has larger plans for his brain painting project, which includes curating a VR art exhibit to expand his audience and develop the first stages of brain-based non-fungible tokens (NFTs) using saved images created by brain-painting artists.

FAQs

What is BrainPaint for ADHD? ›

What is BrainPaint? BrainPaint is a neurofeedback software program administered by professionals. It is designed to improve how the brain functions by training patients to recognize the difference between a focused state and a day-dreaming state, without requiring a brain map.

What parts of the brain are affected by ADHD? ›

Research has shown that in children with ADHD, the prefrontal cortex matures more slowly than typically developing kids. It is also slightly smaller in size. Similarly, the cerebellum, hippocampus, and amygdala are also thought to be smaller in volume in kids with ADHD.

How is an ADHD brain different from a normal brain? ›

Research suggests that the ADHD brain differs from neurotypical brains in a number of ways, including the smaller size of certain brain structures (primarily while kids are still maturing), the level of activity in different areas, and how efficiently key neurochemicals, such as dopamine, are produced and transmitted.

Do people with ADHD have a smaller prefrontal cortex? ›

The ADHD Brain: Structurally Different

Several studies have pointed to a smaller prefrontal cortex and basal ganglia, and decreased volume of the posterior inferior vermis of the cerebellum — all of which play important roles in focus and attention.

What is the success rate of neurofeedback for ADHD? ›

Standard neurofeedback protocols in the treatment of ADHD can be concluded to be a well-established treatment with medium to large effect sizes and 32–47% remission rates and sustained effects as assessed after 6–12 months.

Is neurofeedback for ADHD FDA approved? ›

While the FDA has approved 19-sensor EEG neurofeedback for anxiety, depression, ADHD, OCD, and poor sleep — all of which negatively impact our performance in schools, colleges, at work, and at home — many do not even consider EEG neurofeedback or know that it is a highly effective treatment option.

Is ADHD a mental illness or neurological disorder? ›

Attention deficit hyperactivity disorder (ADHD) is a type of neurological disorder called a neurodevelopmental disorder. ADHD affects your brain and nervous system, like all neurological disorders, but it also affects brain development. ADHD is presumed to be present from birth.

Is ADHD a disability? ›

Under both the ADA and another law known as the Rehabilitation Act of 1973, ADHD is considered a disability in the United States, but with strict stipulations. For instance, ADHD is considered a protected disability if it is severe and interferes with a person's ability to work or participate in the public sector.

Is ADHD genetic from mother or father? ›

Is ADHD inherited from Mom or Dad? You can inherit genes that boost risk for ADHD from your mother, from your father or from both parents. In a recent Norwegian study, inherited risk was somewhat higher when a child's mother had ADHD compared to their father, but researchers weren't certain why that would be.

What does an ADHD meltdown look like? ›

Similarly, people with ADHD can also experience 'meltdowns' more commonly than others, which is where emotions build up so extremely that someone acts out, often crying, angering, laughing, yelling and moving all at once, driven by many different emotions at once – this essentially resembles a child tantrum and can ...

Can ADHD be seen on a brain scan? ›

Brain MRI is a new and experimental tool in the world of ADHD research. Though brain scans cannot yet reliably diagnose ADHD, some scientists are using them to identify environmental and prenatal factors that affect symptoms, and to better understand how stimulant medications trigger symptom control vs. side effects.

How does a person with ADHD think? ›

Individuals with ADHD often experience difficulty regulating their attention, leading to a constant stream of thoughts that are difficult to control. Research suggests that individuals with ADHD may have an imbalance of neurotransmitters, such as dopamine and norepinephrine.

Do people with ADHD talk in their head? ›

Their brain structures are different in that they struggle to organize their thoughts, a function that is aided by self-talk. For ADHD patients, they do not process thoughts in the form of an inner conversation, but they process information as they say it and thus it is difficult for them to keep focused on one point.

What is the breakthrough of ADHD? ›

Summary: Researchers have made a pivotal discovery in ADHD research, finding that the disorder's symptoms are connected to unusual interactions between the brain's frontal cortex and its deeper information processing centers.

Do people with ADHD have certain facial features? ›

Moreover, the depth of the upper face was another measurement value that was strongly associated with the diagnosis of ADHD. The brain and face develop simultaneously in the embryonic process, and therefore, face phenotype occurs in parallel with the changes in the brain.

What is the brainwave for ADHD? ›

Typical brainwave imbalances seen with ADHD and ADD

THETA BRAINWAVES when at a high proportion are associated with incomplete work, disorganization, and being easily distracted. BETA BRAINWAVES are associated with efficient information processing and problem-solving.

What is the brain device for ADHD? ›

Neurofeedback, formerly called electroencephalographic (EEG) biofeedback, and occasionally referred to as neurotherapy, is an intervention for ADHD based on findings that many individuals with ADHD show low levels of arousal in frontal brain areas, with excess of theta waves and deficit of beta waves.

What are the benefits of neurofeedback for ADHD? ›

In another study of 38 children with ADHD, 30 sessions of neurofeedback training (SCP) was reported to improve cognitive function and attention. Additionally, these effects were still seen up to 6 months after the initial treatment. This finding was confirmed by another follow-up study in 23 children with ADHD.

What is the best ADHD therapy? ›

Summary. Studies suggest psychotherapy can reduce symptoms of ADHD, especially when people combine it with medication. There are different types of psychotherapy, and research suggests CBT is the most effective option for people with ADHD. Other options include family therapy.
