Can ADHD Brain Scan Or Neuroimaging Help With ADHD Diagnosis?
Attention Deficit Hyperactivity Disorder (ADHD) affects millions of individuals globally. Adults and children with ADHD tend to experience symptoms like inattentiveness, impulsiveness, and hyperactivity. Despite being a widely diagnosed mental health condition, obtaining an accurate diagnosis for ADHD can still be challenging. Recently, brain scans seem to have become an increasingly utilized tool in diagnosing ADHD. While brain scans offer helpful information in addition to other diagnostic tools, they may not be of much help when it comes to treatment. Online therapy is one way that people with ADHD can learn to better manage symptoms of mental disorders like ADHD.
Exploring neuroimaging for attention deficit hyperactivity disorder
A brain scan for ADHD is a form of neuroimaging that examines the structure and function of the brain. The most used brain scans for patients with ADHD are typically functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET). These scans use magnetic fields and radioactive tracers to produce images of the brain that reveal how it functions.
High-tech brain imaging that measures blood flow and brain wave activity like a functional MRI are likely becoming increasingly popular for diagnosing the condition because they can provide a non-invasive and accurate method of assessing brain function. Functional imaging can also track the region of the brain that’s usually responsible for cognitive functioning, such as decision-making, impulse control, and attention control. This could potentially be used to inform an ADHD diagnosis.
How does ADHD brain scan or neuroimaging work?
During a brain scan for ADHD, the individual being scanned might be asked to complete tasks that activate specific brain regions. For instance, they might be asked to perform a task that requires attention and inhibitory control, such as pressing a button when a particular image appears on a screen and not pushing it if the image doesn’t appear. The scans can demonstrate how different regions of the brain are activated during these tasks, potentially allowing researchers
What information can brain scans or neuroimaging provide?
Brain scans for ADHD may provide valuable information regarding the functioning of the brain in individuals with ADHD. For example, they may show differences in the activity levels of certain brain regions, such as the left temporal lobe, prefrontal cortex, and basal ganglia, which are believed to play a role in attention and inhibitory control. These differences might help to explain some of the symptoms of ADHD, such as inattention and impulsiveness.
Moreover, ADHD brain scans could also be used to differentiate ADHD from other psychiatric disorders that may exhibit similar symptoms, such as depression or anxiety. By observing the specific patterns of brain activity in individuals with ADHD, researchers and clinicians may better understand the underlying causes of the disorder and develop more effective treatment plans. For example, studies have shown that methylphenidate treatment improves ADHD symptoms and impacts brain activity.
The potential role of brain scans in ADHD diagnosis
Brain scans for ADHD are not presently used as the sole means of diagnosing ADHD. Instead, they are typically utilized as a tool to support a diagnosis that has been made, based on a comprehensive evaluation of the individual's symptoms and behaviors.
The American Psychiatric Association (APA) suggests that a proper diagnosis of ADHD should be made by a licensed mental health professional, such as a psychologist or psychiatrist, based on a thorough evaluation of the individual's symptoms, behaviors, and medical history. When evaluating patients for ADHD, health professionals look for the signs and symptoms described in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). While ADHD brain scans could provide valuable information regarding the functioning of the brain, they are not always required for making a diagnosis of ADHD. In many cases, a comprehensive evaluation of the individual's symptoms and behaviors are sufficient to make a diagnosis.
However, in certain cases, ADHD brain scans might be helpful in making a diagnosis. For instance, if the individual's symptoms are not clearly indicative of ADHD or if they have other conditions that might contribute to their symptoms, such as a mood disorder, a brain scan for ADHD could provide additional information to clarify the diagnosis. Ultimately, the decision to use ADHD brain scans in the diagnostic process is generally made on a case-by-case basis.
If a scan does not indicate a likelihood of ADHD, it can lead a healthcare provider to evaluate a patient for other conditions such as head trauma or learning disorders.
Limitations of ADHD brain scans
It can be crucial to keep in mind that ADHD brain scans are not necessarily a perfect diagnostic tool and can have several limitations. Firstly, the results of ADHD brain scans can be influenced by various factors, such as the individual's age, gender, and overall health. Secondly, the technology utilized in ADHD brain scans tends to constantly evolve, and the interpretation of functional connectivity can be subjective, potentially leading to inaccuracies.
Additionally, while ADHD brain scans can provide valuable information regarding the functioning of the brain, they may not provide a complete picture of the individual's overall health and well-being. It can also be important to note that not all individuals with ADHD may exhibit the same brain activity patterns and that there is still much that is unknown about the relationship between brain activity and ADHD.
Role of online therapy in treating ADHD
Online therapy can play an important role in the treatment of ADHD, potentially providing individuals with the tools and support they deserve to manage their symptoms and lead fulfilling lives. Therapy can help individuals with ADHD develop coping mechanisms for their symptoms, such as inattention and impulsiveness, and improve their relationships with others. Being able to attend therapy sessions from the comfort and convenience of home can make it more convenient to get professional help, particularly for children with ADHD, and online therapy is often more affordable than in-person therapy at a clinical practice.
Benefits of online therapy
According to a study published in the Journal of Attention Disorders, therapy can be a crucial component in the treatment of ADHD, providing individuals with the skills and support they need to manage their symptoms and improve their overall functioning. The study found that individuals with ADHD who received therapy experienced significant reductions in symptoms such as inattention, impulsiveness, and hyperactivity, and improved their ability to manage their emotions and relationships with others. Additionally, therapy was found to be effective in reducing the frequency and severity of co-occurring mental health conditions, such as depression and anxiety. As this study explains, online therapy is typically as effective as in-office therapy, making either one a valid choice for those looking for professional help with their ADHD symptoms.
Takeaway
ADHD brain scans can be useful diagnostic tools for a variety of health concerns, from neurological disorders to ADHD. However, there can be certain limitations to consider when using brain scans for diagnostic purposes, such as the individual's age, gender, and overall health. Studies have found that therapy can be effective in assisting individuals in reducing the frequency and severity of their ADHD symptoms and improving their ability to manage their emotions and relationships with others.

Can you detect ADHD (Attention Deficit Hyperactivity Disorder) from neuroimaging?
Brain scans are used to study ADHD but aren’t typically used to diagnose it. Researchers have used single-photon emission computed tomographies (SPECT scans), functional magnetic resonance imaging tests (functional MRIs), and positron emission tomographies (PET) to study brain structure and function in relation to ADHD.
One FDA-approved test to help clinicians diagnose ADHD in individuals from ages 6 to 17 is the Neuropsychiatric EEG-Based Assessment Aid (NEBA) system. This test is designed to measure the number and type of brain waves emitted by brain cells per second. While this test isn’t designed to be used in lieu of clinical evaluations to provide a psychiatric diagnosis, it may be used in conjunction with a physical assessment and the patient’s medical history.
Why isn't neuroimaging used to diagnose ADHD?
Researchers typically believe that brain imaging scans alone can’t provide a diagnosis of ADHD. However, in unclear cases, imaging studies may provide insight into a person’s brain activity. For example, during a SPECT test, a patient receives an injection of an isotope that can then help doctors measure blood flow in the brain. This test tends to show which brain areas are active and which are quiescent (more inactive) as the patient engages in an activity. While there is some controversy about the effectiveness of this test, it may offer insight into a person’s symptoms and possible treatments. Ultimately, clinical diagnoses can only be provided by a licensed clinician.
Can people with ADHD lead normal lives?
People with ADHD can lead normal, fulfilling lives with the right treatment and strategies for managing their symptoms.
What can neuroimaging reveal?
Brain tests may reveal differences in brain activity. For example, a person living with ADHD may have decreased activity in the prefrontal cortex. They may also have differences in functional connectivity in certain areas of the brain as well as differences in theta waves and beta waves.
How does an ADHD brain work?
A person who experiences ADHD typically has a brain with the same functions as everyone else’s, but there may be differences in blood flow and activity in certain areas, as well as differences in brain wave patterns.
Why do ADHD brains work faster?
A person living with ADHD may feel like they have a brain that works faster. This may be related to a craving for more stimulation. With the right strategies, a person who experiences this may be able to harness this energy to their advantage. They may also benefit from medication and/or therapy to address feelings of hyper-arousal.
How does the ADHD brain differ from normal brain blood flow?
A person with ADHD may have increased blood flow in certain areas of the brain and decreased activity in other areas of the brain.
What part of the brain is affected by ADHD?
The prefrontal cortex of the brain may have decreased activity in a person with ADHD. Also, certain parts of the brain, such as the frontal lobe, may be smaller in kids living with ADHD. However, some areas of the frontal lobe may develop further as they get older.
Why do ADHD brains get distracted?
People who experience ADHD may get distracted for several reasons, including differences in the frontal lobe, which typically helps with attention and impulse control. Future research, including studies using brain MRIs and artificial intelligence, may reveal more about why people living with this neurodevelopmental disorder sometimes get distracted.
Why do ADHD brains need more sleep?
According to Children and Adults with Attention-Deficit/Hyperactivity Disorder (CHADD), people with ADHD may experience difficulty sleeping. Their symptoms may prevent healthy sleep, and this lack of sleep may worsen their symptoms. A lack of sleep can affect executive functions, which can impact a person’s ability to organize information, begin tasks, and assess the consequences of their actions.
