Attention-Deficit/Hyperactivity Disorder (ADHD) is often recognized as the most commonly misdiagnosed mental disorder. One crucial aspect that can lead to misdiagnosis is the failure of professionals to consider vision-related factors. In this blog, we’ll explore how vision deficiencies overlap with ADHD symptoms and the importance of consulting with an appropriate eye care specialist for a comprehensive functional vision test.
Overlapping Symptoms
Many symptoms associated with vision deficiencies closely resemble those of ADHD. For instance:
• Accommodation Insufficiency: This condition reduces the ability to swiftly shift focus at various distance and sustain focusing ability, making it challenging for children to concentrate on their schoolwork.
• Convergence Insufficiency: This issue affects eye teaming and can lead to blurry or double vision. Both conditions may be misinterpreted as “inattention,” a hallmark of ADHD.
• Retained Primitive Reflexes: This may cause sensory overload, particularly in visually stimulating environments like classrooms. The inability to process visual information effectively can lead to behaviours such as fidgeting, restlessness, or excessive movement, which may mimic hyperactivity associated with ADHD.
When children struggle to see clearly, their motivation to concentrate diminishes, making them more susceptible to distractions. For instance, if a child has difficulty processing visual information due to sensory overload, they may exhibit spontaneous behaviours, like running around, moving, chatting and similar, which can be mistakenly classified as hyperactivity.
Visual Processing and Social Interactions
Children with vision deficits may also struggle with visual processing or discrimination, leading to difficulties interpreting facial expressions or social cues. Neuroscience suggests that these challenges can hinder a child’s ability to engage socially, potentially being misinterpreted as a “social communication deficit” often associated with Autism Spectrum Disorder (ASD).
Impulse Control and Emotional Outbursts
Poor impulse control and frequent emotional outbursts are common in both ADHD and vision-related issues. Here’s how vision deficiencies contribute to these behaviours:
Stress Response: Accommodation and convergence insufficiencies can lead to stress. When the eyes strain, the body’s sympathetic system activates, releasing epinephrine, which increases cortisol levels. This physiological response can trigger anxiety and frustration.
Mental Fatigue: Struggling with visual tasks requires additional cognitive effort. This increased demand can overwhelm the prefrontal cortex, leading to rumination, impulsivity, and maladaptive behaviours.
Retained Primitive Reflexes, particularly Moro reflex could lead into very abrupt and inadequate response if the child is pressurised to the level which leads to sensory overload.
Importance of a Comprehensive Eye Assessment and Vision Therapy
Given the significant overlap between vision issues and ADHD symptoms, it’s crucial for parents and educators to consult an eye care specialist. A comprehensive eye test and insight into the state of the Neural Development can reveal underlying vision problems that may be affecting a child's behaviours and academic performance. If a vision deficiency is diagnosed, vision therapy may be recommended. In case of presence of the retained primitive reflexes the home based exercises would be prescribed to be done on daily basis. This treatment can help improve visual skills and alleviate symptoms, thereby enhancing the child's ability to focus and engage in daily activities.
Tips for Parents
Before implementing any strategies for managing ADHD symptoms, ensure that a thorough vision evaluation has been conducted. Here are some helpful tips:
Seek a Comprehensive Eye Test: Schedule an appointment with an eye care specialist who can conduct a detailed vision assessment.
Screen for the presence of the Primitive Relfexes
Monitor Symptoms: Keep track of your child’s behaviours in different settings to identify patterns that may indicate a vision issue rather than ADHD.
Educate Yourself: Learn about the signs of Vision Deficiencies and Primitive Reflexes how they can overlap with ADHD symptoms. This knowledge can empower you to advocate for your child’s needs effectively.
Collaborate with Professionals: Work with both eye care providers and mental health professionals to create a holistic approach to your child’s well-being.
Conclusion
Misdiagnosing ADHD due to overlooked vision deficiencies can have long-lasting impacts on a child's life. By understanding the connection between visual health and attention-related behaviours, parents and professionals can ensure that children receive the appropriate care and support. If you suspect your child may be experiencing vision-related challenges, don’t hesitate to consult with an eye doctor for a comprehensive vision test today.
