Your eyes don’t just see—they inform your brain. In this episode of Facilitated, Dr. Mitchell Rasmussen sits down with neuro-optometrist Dr. Alexandra Talaber to unpack how vision connects to attention, mood, balance, and recovery. We explore why eyesight is only one piece of “seeing,” how convergence insufficiency and visual processing issues often masquerade as ADHD or anxiety, and why neuro-optometry and functional medicine share the same goal: finding what’s really behind the symptom. From concussion recovery to childhood focus struggles, this conversation reframes vision as brain health—and shows how retraining the eyes can change the entire nervous system.
Vision isn’t just about clarity—it’s how your brain organizes the world. Neuro-optometry reveals how retraining visual pathways can improve focus, mood, and performance at any age.
Vision Is More Than 20/20
Vision is so much more than reading an eye chart. This episode reframes sight as a full-body, brain-wide process that shapes attention, balance, mood, and even recovery after injury. Neuro-optometry looks at how the eyes team, focus, and track—and how the brain interprets the flood of visual data. When those systems are off, the clues often hide in plain sight: headaches, fatigue, light sensitivity, re-reading lines, losing your place, or anxiety in crowded spaces. We unpack why kids rarely mention double vision, why adults blame mood or willpower, and how targeted therapy can literally retrain the visual system.
The goal isn’t stronger glasses—it’s understanding how the brain sees.
When Focus Fails
One of the most overlooked culprits behind “attention” or reading issues is convergence insufficiency—when the brain struggles to pull the eyes inward for near work. It affects about one in ten people, often shows up after concussions, and is three times more common in ADHD. The brain burns extra energy just to keep words single and clear, which can look like distraction or restlessness rather than true inattention.
No prescription will fix this. What helps is training that restores alignment, depth, and smooth tracking. People often cope by suppressing one eye or gravitating toward screens because audio and motion are easier for the brain to process. Once the visual system stops fighting itself, focus improves naturally.
“When the visual system stops fighting itself, focus improves naturally.” Dr. Alex Talaber, FACILITATED Episode 43
Rewiring Vision—and the Brain
Vision therapy works because neuroplasticity works. Sessions are short (about 45 minutes a week) with 15-minute home practices that keep the brain’s momentum going. Frequent, gentle reminders beat sporadic effort every time. Clinicians pace therapy carefully, especially when dizziness or vestibular symptoms are in play, to avoid tipping the nervous system into fight-or-flight.
The process builds step by step: clarity, focusing stamina, eye teaming, tracking, then higher-level processing like visual memory and figure-ground.
The result isn’t just better vision—it’s better stability, balance, and comfort in your own body. When the visual world feels steady, so do you.
The Metabolic Connection
Metabolic health fuels visual recovery. The retina is one of the body’s most energy-hungry tissues, constantly burning through fuel and antioxidants to handle light exposure. In one real case, retinal “fatty deposits” revealed severe lipid and blood-sugar dysfunction long before lab results confirmed it. Coordinated care addressed both metabolism and visual performance.
Nutrients like B-vitamins, omega-3s, and macular pigments (lutein, zeaxanthin) are critical for neuronal resilience. Patients can literally rebuild macular pigment through diet and supplements, reducing light sensitivity and slowing degeneration in high-risk individuals.
“You can literally see the difference—feed the system better, and the vision follows.”
Fast Wins and Real Recovery
Not every breakthrough takes months. In one striking stroke case, yoked prism lenses shifted spatial perception just enough to unlock downward eye movement within minutes. That kind of quick success proves what’s possible—and motivates long-term work to make it permanent.
Compare that with the old “just patch one eye” approach for double vision, which quiets symptoms but shuts off half the brain’s visual input. With prisms and therapy, many cranial nerve palsy patients recover alignment and depth perception in weeks, not months—getting back to driving, working, and living fully. Whether it’s a kid who finally enjoys reading or an adult who feels calm in a busy room, the pattern holds: when vision stabilizes, everything else steadies too.
Healing Is a Team Sport
The bigger takeaway is collaboration. Neuro-optometry pairs beautifully with functional medicine, vestibular rehab, occupational therapy, and physical therapy when timing and sequencing are thoughtful.
Many “dizzy” patients don’t have a vestibular problem at all—it’s vision-vestibular coupling gone haywire. Treat the visual system first or alongside, and progress finally sticks.
Healing happens in layers: fuel the neurons, oxygenate tissues, lower inflammation, and retrain the brain step by step. Replace “try harder” with “work smarter.” When we respect how the brain sees, people regain focus, confidence, and a map of the world that finally feels clear.

Key Takeaways from Episode 43:
Vision is brain function, not just eyesight. Over half of the brain is devoted to visual processing. Neuro-optometry looks beyond visual acuity to how the brain and eyes communicate—impacting focus, mood, learning, balance, and recovery.
Convergence insufficiency is common and treatable. Around 10% of people experience this issue, where the eyes don’t work together effectively at close range. It’s three times more common in those with ADHD and can mimic attention or reading difficulties—but can be corrected through vision therapy at any age.
Anxiety and overstimulation can stem from visual dysfunction. When the brain struggles to stabilize visual input, the thalamus (a hub for both vision and emotion) can amplify anxiety and stress responses.
Healing the visual system requires the same inputs as any other neural recovery. Oxygen, fuel (blood sugar balance and nutrient sufficiency), and stimulation all matter. Vision therapy works best when paired with movement, nutrition, and metabolic health.
The eyes can reveal early signs of systemic health issues. Retinal changes—like fatty deposits—can point to metabolic dysfunction, insulin resistance, or vascular stress long before symptoms appear elsewhere.
Neuroplasticity takes time, but recovery is possible. Whether retraining the visual system after a concussion or stroke, or improving focus and balance, consistent therapy and lifestyle changes can permanently rewire brain pathways.

Facilitated Podcast Episode 43| Vision, the Brain, and Healing: A Conversation with Dr. Alexandra Talaber
Mitchell: Today’s conversation is one I’ve been looking forward to for a long time. If you’ve followed our work, you know we’re obsessed with how everything in the body connects—your brain, hormones, gut, environment—all of it. But one system that doesn’t get nearly enough attention is vision.
Before meeting Dr. Alex, I thought vision was just about how well you can read an eye chart. What I’ve learned since is that vision is deeply tied to how your brain processes information, impacting focus, coordination, learning, mood, and even recovery after head injuries.
Our guest today, Dr. Alexandra Talaber, is a neuro-optometrist whose work completely reframed how I think about vision and the brain. She helps people recover from concussions, brain injuries, and focus or performance issues, including ADHD.
Dr. Talaber is a board-certified neuro-optometrist and fellow of the Optometric Vision Development and Rehabilitation Association and the American Academy of Optometry. She’s a clinical professor, researcher, and founder of the NeuroVision Therapy Institute in Cherry Creek, Denver, where she and her team use a holistic, evidence-based approach to treat complex vision conditions.
Alex, welcome.
Dr. Alex Talaber:
Thanks so much for having me—it’s great to be here.
Mitchell:
Let’s start with the basics. For those unfamiliar, what exactly is a neuro-optometrist?
Dr. Talaber:
A neuro-optometrist diagnoses and treats vision issues that originate in the brain or nervous system. We start with traditional optometry training, but then go deeper into how the eyes and brain communicate. About half of the brain is involved in visual processing, so it’s incredibly complex. Neuroscience research has really helped shape this field over the last decade.
Mitchell:
You once told me you’re not a primary care optometrist, even though you have that training. What does that mean in practice?
Dr. Talaber:
It means I’m not just handing out stronger prescriptions. If someone’s vision keeps getting worse, that’s a red flag—something deeper is going on. I’m more interested in how vision functions and how it affects daily life—reading, driving, working—not just clarity on an eye chart.
Mitchell:
That’s what blew my mind when we met. I’d always believed vision was fixed, not trainable. But you showed me it’s highly connected to brain plasticity. Can you talk about that connection—and why visual problems are often missed after concussions or trauma?
Dr. Talaber:
Absolutely. Vision has several components: clarity (acuity), focusing stamina, eye alignment, and tracking—all of which affect how the brain interprets what it sees. After a concussion, any of these systems can malfunction. Beyond that, we have visual processing—how the brain interprets, remembers, and organizes visual input. If those pathways are disrupted, people struggle with reading, attention, and even emotional regulation.
Mitchell:
That makes sense. When I first saw you, you diagnosed me with something called convergence insufficiency. Can you explain that?
Dr. Talaber:
Convergence insufficiency affects about 10% of the population and is three times more common in people with ADHD. It means the brain has trouble pulling the eyes inward to focus on near tasks, like reading. The result is fatigue, headaches, or losing your place while reading—often mistaken for attention issues. The good news is it’s very treatable at any age, thanks to neuroplasticity.
Mitchell:
Is that why you keep reminding me to do my vision therapy homework?
Dr. Talaber:
Exactly! Everything gets easier once the eyes start working together efficiently.
Mitchell:
You also mentioned anxiety can connect back to this—how?
Dr. Talaber:
The thalamus, part of the brain involved in emotion, also processes vision. When vision feels unstable, it can trigger anxiety or a constant sense of overstimulation. I’ve seen patients’ anxiety resolve entirely after completing vision therapy.
How Vision Therapy Works
Mitchell:
You often say vision therapy is really brain therapy. How does it work?
Dr. Talaber:
We retrain how the brain and eyes work together. Sessions are usually 45 minutes, once or twice a week, with short daily home exercises. For conditions like convergence insufficiency, the therapy focuses on improving binocular vision—how both eyes align and fuse images together. Over time, this changes how the brain processes spatial awareness, balance, and attention.
Mitchell:
And if a patient feels dizzy or over-stimulated?
Dr. Talaber:
We adjust. Vision therapy should gently challenge the nervous system without triggering fight-or-flight. Our therapists are trained to pace it carefully. For patients with both vestibular and vision dysfunction—like after a concussion—we collaborate with physical and occupational therapists to sequence the care properly.
The Metabolic Connection
Mitchell:
You once referred a patient to us after seeing fatty deposits in her retina. That led to finding extreme triglyceride levels and metabolic dysfunction. I was amazed that an eye exam could pick that up.
Dr. Talaber:
The eye’s blood vessels are tiny—similar to those in the kidneys—so we can detect vascular issues early. When I saw those retinal exudates, I knew there was likely a systemic issue. The eyes truly are windows to overall metabolic and cardiovascular health.
Mitchell:
It was such a good example of how our work overlaps—your neural and visual system insight meets our functional medicine perspective. We can’t separate the biology of vision from metabolism, nutrients, and inflammation.
Dr. Talaber:
Exactly. Neuroplasticity and healing take time, and they require good fuel—movement, oxygen, and nutrition. Even though I’m not running labs like you are, I always encourage patients to support brain health through diet, exercise, and lifestyle.
Case Highlights and Recovery Stories
Dr. Talaber:
Lately, I’ve seen a lot of cranial nerve palsy and stroke patients. One that stands out is a 40-year-old man who had a bilateral thalamic stroke and lost the ability to look downward. During his evaluation, I trialed prism lenses that shifted his spatial world slightly upward—and suddenly, he could move his eyes down again for the first time. It was incredible. We’ll now use therapy to make that change permanent.
Mitchell:
That’s amazing. And you see similar results with micro-strokes?
Dr. Talaber:
Yes, especially when treated early. Traditional care often just patches one eye to eliminate double vision, but that shuts down brain input. I use prism lenses and targeted therapy to retrain alignment. With early treatment, some recover in as little as three weeks.
Mitchell:
Pain—or fear—is a powerful motivator. And what you’re describing mirrors what we see with physical rehabilitation: the earlier and more intensive the therapy, the better the recovery.
Dr. Talaber:
Exactly. It’s about giving the brain the right input to rewire itself.
The Bigger Picture
Mitchell:
That’s what I love about your work—it shows that healing is really about giving the body and brain permission to reconnect. Whether we’re talking hormones, metabolism, or vision, the principle is the same: too much bad, not enough good. Our job is to rebalance that equation.
Dr. Talaber:
And even introducing a little bit of hope creates measurable physiological change. The brain responds to that.
Mitchell:
Well said. And likewise, I’m so grateful for the work you do. We send patients your way because you take their challenges seriously and give them a plan forward.
Dr. Talaber:
Thank you—and thank you both for the care and collaboration you offer. It’s an honor to work with you.
