Neurodegenerative Conditions & Visual Function
Supporting Quality of Life with a Neurodegenerative Condition
When a loved one is diagnosed with Alzheimer’s, dementia, or another neurodegenerative condition, the focus is on memory and cognitive function. But up to 60% of individuals with these conditions also have significant, often undiagnosed, vision problems that can worsen their symptoms and accelerate their decline. At Brain Vision Institute, we provide specialized neuro-visual care to optimize remaining function, improve quality of life, and support both patients and caregivers on this challenging journey.
Your brain uses
of its energy just to process visual input.
The Hidden Visual Component of Cognitive Decline
It can be heartbreaking to watch a loved one struggle with a neurodegenerative disease. They may seem confused, disoriented, or agitated, and it’s natural to assume it’s all due to the disease itself. But often, a hidden vision problem is making everything worse. The brain uses an immense amount of energy to process vision; when this system is compromised, it puts an even greater strain on an already struggling brain.
Have you noticed your loved one experiencing any of the following?
- Difficulty recognizing familiar faces or objects
- Becoming easily lost or disoriented, even in familiar places
- Increased agitation, anxiety, or withdrawal in busy environments
- Bumping into furniture or having trouble navigating doorways
- Difficulty with activities like eating (e.g., finding food on their plate)
- Reporting visual hallucinations (seeing things that aren’t there)
These are not just symptoms of dementia; they are often signs of a treatable visual processing problem that is compounding the effects of the neurodegenerative disease.
When the Brain Can’t Make Sense of What the Eyes See
Neurodegenerative diseases like Alzheimer’s don’t just affect memory; they damage the parts of the brain responsible for interpreting and making sense of visual information. The eyes may be healthy, but the brain can’t process the signals correctly [1].
Alzheimer’s Disease:
The most common form of dementia. Visual symptoms can include:
Visual-Spatial Disorientation:
Difficulty judging distances, navigating spaces, and understanding where objects are in relation to one another.
Facial Agnosia:
An inability to recognize familiar faces, even those of close family members.
Reduced Contrast Sensitivity:
Difficulty distinguishing objects from their background, making it hard to see steps or food on a plate.
Lewy Body Dementia:
This condition is often characterized by significant visual symptoms, including:
Vivid Visual Hallucinations:
Seeing people, animals, or objects that are not there. This can be very distressing for both the patient and caregiver.
Fluctuating Cognition:
Periods of clarity mixed with periods of confusion, often linked to fluctuations in visual processing ability.
Posterior Cortical Atrophy (PCA):
Sometimes called the “visual variant” of Alzheimer’s, PCA primarily affects the back of the brain, which is responsible for visual processing. Early symptoms are almost entirely visual, such as difficulty reading, navigating, and recognizing objects [2].
Research shows that these visual deficits can appear years before a formal diagnosis of dementia, making a comprehensive visual-cognitive assessment a critical tool for early detection [3].
Optimizing Vision to Lighten the Cognitive Load
Our CogniViiSION® Longevity Framework is designed to support individuals with neurodegenerative conditions by optimizing their visual function, thereby reducing the strain on their brain and improving their quality of life.
The Comprehensive Visual-Cognitive Assessment
1
We conduct a specialized evaluation to understand how the neurodegenerative process is affecting your loved one’s visual system. We assess visual-spatial skills, contrast sensitivity, facial recognition, and visual processing speed. This helps us differentiate between what is a primary vision problem and what is a cognitive one.
Your Personalized Supportive Care Plan
2
Our goal is not to cure the underlying disease, but to improve functional vision and quality of life. The plan is tailored to the individual’s specific needs and may include:
- Therapeutic Lenses: Using specific tints and coatings to enhance contrast, reduce glare, and minimize visual confusion.
- Environmental Modifications: Providing practical advice on how to adapt the living environment to be more visually friendly (e.g., using high-contrast colors, improving lighting, reducing clutter).
- Caregiver Education: We work closely with caregivers to help them understand the visual challenges their loved one is facing and provide strategies to improve communication and reduce frustration.
Improving Quality of Life for Patients and Caregivers

By addressing the visual component of a neurodegenerative disease, we can often reduce agitation, improve communication, and enhance safety. This not only improves the patient’s quality of life but also eases the immense burden placed on caregivers.
Finding Moments of Clarity and Comfort
Frequently Asked Questions
Q1: Can you treat my loved one’s dementia?
A1: No. We do not treat the underlying neurodegenerative disease. Our role is to identify and manage the visual symptoms associated with the disease to improve function and quality of life.
Q2: My loved one is in a memory care facility. Can you still help?
A2: Yes. We can work with your loved one and their care team at the facility to implement visual strategies and environmental modifications to improve their comfort and safety.
Q3: Is it worth doing an evaluation if the disease is already advanced?
A3: In many cases, yes. Even small changes, like improving contrast sensitivity or reducing glare, can make a significant difference in a person’s daily comfort, safety, and level of agitation.
Q4: How can vision problems be an early sign of Alzheimer’s?
A4: The back of the brain, which is responsible for processing vision, is one of the first areas to be affected by the plaques and tangles that cause Alzheimer’s. As a result, subtle visual-spatial problems can often be detected years before significant memory loss occurs [4].

Supporting You and Your Loved One, Every Step of the Way.
Caring for someone with a neurodegenerative disease is an immense challenge. Addressing the visual component can provide a new avenue for improving their comfort and your connection with them. Schedule a compassionate and comprehensive visual-cognitive evaluation to see if we can help.
