Primary care physicians play a pivotal role in identifying underlying factors that significantly impact patient health outcomes. One often overlooked factor is the connection between literacy, attention-deficit/hyperactivity disorder (ADHD) and health care costs. A deeper understanding of this relationship can help tailor patient care and improve outcomes. This article examines how literacy challenges associated with ADHD can affect overall patient well-being and offers insights that may inform approaches to patient management and referrals.

Health risks associated with low literacy

Connie McReynolds, PhD

Low literacy levels are linked to an estimated $230 billion in annual U.S. health care costs, largely due to increased hospital admissions, emergency room visits and medication errors. Illiteracy is also correlated with higher rates of chronic health conditions, mental health problems, poorer adherence to medical instructions and increased mortality.Individuals with low literacy are more likely to experience hospitalization and report poorer general health status,often due to delayed medical treatment and limited use of preventive health services.

Given these significant health risks and associated costs, it is critical to recognize one of the key underlying contributors to low literacy is ADHD. The connection between ADHD and literacy difficulties is frequently overlooked but plays a pivotal role in shaping long-term health outcomes.

ADHD and literacy

Nearly half of Americans struggle to comprehend health information, with more than 30 million adults reading below a third-grade level. Globally, 20% of the population is illiterate, while an additional 3 billion face basic literacy challenges. ADHD plays a significant role in these literacy deficits by impairing attention, focus and inhibition control — skills essential for reading comprehension when processing written information and following verbal instructions.

The underlying cause of ADHD difficulties often stems from auditory and visual processing problems, which are critical but frequently unrecognized factors in literacy development. These processing challenges disrupt the brain’s ability to interpret and use auditory and visual information effectively, which impacts comprehension. As a result, individuals with ADHD may have a harder time understanding medical instructions, leading to poorer health outcomes.

Understanding processing problems

Auditory and visual processing problems stem from the brain’s difficulty in interpreting and utilizing information, not from problems with hearing or vision itself. These processing problems disrupt cognitive functions crucial for learning, including focus, attention, memory and task completion.

Effective information processing and attention are interconnected, forming the foundation for learning and daily functioning. For learning to occur, the brain must process information and maintain attention — both essential for effectively navigating in the world.

Auditory processing challenges arise when the brain struggles to interpret and retain spoken information, despite normal hearing function. Patients with auditory processing difficulties may present with symptoms such as difficulty sustaining attention in noisy environments, challenges following extended conversations, impaired comprehension and trouble following multistep verbal instructions, often leading to misunderstandings.

Visual processing challenges occur when the brain has difficulty interpreting visual information, such as organizing details or accurately processing written material. Unlike vision deficits that can be corrected with glasses, these challenges involve how the brain interprets visual input. Symptoms of visual processing difficulties may include disorganization, distractibility, poor hand-eye coordination, frequent tripping or bumping into objects, difficulties with legible writing and struggling with mathematical tasks.

Communication strategies for processing problems

Effective communication is essential when working with patients who experience auditory or visual processing difficulties. Although these challenges do not reflect cognitive deficits, they can impede the patient’s ability to comprehend or retain information.

By adopting targeted strategies to address these processing challenges, health care providers can improve patient understanding and engagement, contributing to better health outcomes. The following communication techniques provide practical approaches to promote clarity and ensure comprehension during clinical interactions.

• Support multimodal comprehension: Enhance patient understanding by using multiple formats, integrating verbal explanations with written materials. Utilize visual aids, such as diagrams or charts, when appropriate, and recommend text-to-speech applications for patients who benefit from auditory processing support.
• Minimize distractions: Optimize focus by reducing background noise and visual clutter. Maintain direct eye contact and provide clear, concise written instructions, supplemented with visual aids as needed.
• Simplify, reinforce and confirm understanding: Use clear, concise language and break instructions into manageable steps. Pause regularly to assess comprehension, encouraging patients to restate or demonstrate understanding. Reinforce key points by having patients repeat the information to ensure accuracy and clarify as needed.

While these strategies can enhance patient interactions, they primarily target symptoms rather than the underlying causes of ADHD, which often stem from auditory and visual processing deficits. Neurofeedback offers a more comprehensive approach by directly targeting neural pathways, potentially reducing long-term reliance on compensatory strategies. This innovative approach is reshaping ADHD management and improving literacy outcomes.

Neurofeedback: An innovative approach to ADHD

Neurofeedback has emerged as a promising, noninvasive approach for addressing both ADHD and literacy challenges in children and adults. By training the brain to enhance attention and focus through repetitive exercises, neurofeedback can improve cognitive functions critical for reading comprehension and learning. This approach not only strengthens attention but also holds the potential for sustained improvements in reading skills, making it a viable option for addressing literacy challenges. To illustrate the potential impact of neurofeedback, consider the case of Isaac, an 11-year-old client with complex ADHD and emotional challenges. (The client’s name has been changed to protect their identity.)

Isaac came to my clinic with emotional disturbance and ADHD diagnoses. His behaviors included impulsivity, emotional disruption, potential for self-harm, decreased focus, history of family conflict, overstimulation by loud sounds, sensitivity to chaos and being “hyper.” Conventional treatments, including medications and behavioral interventions, had failed to produce lasting changes. Our assessment revealed severe impairments in Isaac’s auditory and visual comprehension, underlying his significant learning difficulties and frustrating both caregivers and teachers with his persistent disruptive behaviors.

After 20 hours of neurofeedback training, Isaac exhibited significant improvements, including greater self-control and a reduction in undesirable behaviors. These changes contributed to enhanced comprehension and learning abilities. With decreased impulsivity and emotional disruptions, Isaac showed improved focus and concentration, which translated to better academic performance and strengthened reading skills.

While primary care physicians may not directly provide neurofeedback, understanding its therapeutic benefits enables them to make informed referrals and counsel patients on treatment options that can enhance literacy, cognitive function and overall health outcomes.

Primary care physician guidelines

Primary care physicians play a crucial role in addressing the connection between ADHD, literacy challenges and health care costs. Unrecognized ADHD can hinder patients’ ability to manage health information, resulting in poorer outcomes and higher costs. Early identification and targeted interventions can improve outcomes and reduce expenses. The following guidelines offer strategies for managing ADHD and literacy concerns in clinical practice.

Screen for cognitive and literacy challenges: Routinely assess patients for ADHD, learning disabilities and literacy deficits, especially when they affect comprehension and management of health information. Early detection is key to optimizing care and outcomes.

Explore comprehensive treatment options: When standard interventions are insufficient, refer patients to specialized programs like neurofeedback, cognitive behavioral therapy or literacy support services to address both cognitive and literacy challenges, improving outcomes.

Provide patient education: Explain how addressing ADHD-related cognitive challenges can improve literacy, enhance health outcomes and reduce long-term health care costs. Clear communication ensures patients understand the benefits of targeted interventions.

Implement health literacy strategies: Adapt communication to patients’ literacy levels by using plain language and visual aids and having them recap the information to ensure understanding.

Collaborate with specialists: Refer and coordinate with psychologists and educational specialists to ensure patients with ADHD and literacy challenges receive comprehensive, multidisciplinary support for optimal management and outcomes.

By recognizing these challenges and recommending targeted interventions, primary care physicians can play a crucial role in improving both literacy and overall health care outcomes for their patients.

Conclusion

The global costs of illiteracy — $1.5 trillion annually — underscores the urgency of addressing this crisis. Neurofeedback presents a promising alternative to traditional ADHD treatments, offering potential improvements in literacy and, consequently, health care outcomes.

A mere 10% reduction in illiteracy could yield significant benefits: fewer hospital visits, reduced health care costs and an estimated $25.4 billion in annual Medicare savings.Primary care physicians are uniquely positioned to contribute to this change.

Recognizing ADHD’s impact on literacy, considering neurofeedback referrals when appropriate and implementing health literacy strategies can significantly improve patient outcomes. Each interaction offers an opportunity to enhance individual health and contribute to broader public health benefits.
