Alzheimer’s disease is a progressive brain disorder that impacts memory, thinking, and behavior. It is the most common form of dementia, affecting millions of people worldwide. Currently, there is no cure for Alzheimer’s, but there are treatments that can help to slow the progression of the disease and improve symptoms. One such treatment is red light therapy. Emerging research shows red light therapy can reverse Alzheimer’s symptoms. But does exposing Alzheimer’s patients to red light therapy actually help?

In this blog post, we will explore the science behind red light therapy and its potential benefits for individuals with Alzheimer’s disease. We will also provide tips on how to choose the right red light therapy device for your needs.
Understanding Alzheimer’s Disease
Alzheimer’s disease is a progressive, irreversible brain disorder characterized by a steady decline in cognitive function. It accounts for 60-80% of all dementia cases. The earliest symptom of Alzheimer’s is usually difficulty remembering new information. As the disease advances, symptoms get more severe and can include:
– Impaired reasoning, judgment, and problem-solving
– Disorientation to time and place
– Decline in language and communication ability
– Behavioral changes like depression, apathy, or agitation
– Inability to care for oneself or carry out daily tasks
In final stages, Alzheimer’s patients lose the ability to respond to their environment. Life expectancy after diagnosis averages just 8-10 years. For families, the steady decline of their loved one’s health and mind is heartbreaking. Caring for an Alzheimer’s patient becomes extremely demanding and stressful. And with no cure available, treatment costs for Alzheimer’s topped $290 billion in 2019 alone. Understanding what causes Alzheimer’s is key to finding better treatments. Let’s look at the contributing factors.
What Causes Alzheimer’s Disease?
While all the root causes are still unknown, scientists have identified key factors that likely work together to damage brain cells in Alzheimer’s patients:
One of the hallmarks of Alzheimer’s is an accumulation of protein fragments called beta-amyloid outside nerve cells in the brain. These sticky amyloid plaques are believed to destroy synapses and interrupt neuronal communication, leading to cognitive decline.
Damaged and dying neurons in the Alzheimer’s brain contain twisted strands of a protein called tau. These neurofibrillary tangles block nutrients and other essential substances from reaching brain cells, causing them to die. This fuels Alzheimer’s progression.
Many experts believe genetics load the gun for Alzheimer’s disease. Having certain alleles of the genes APOE, APP, and PSEN1/2 increases your risk of developing Alzheimer’s. However, lifestyle and environmental factors likely still have to pull the trigger.
Blood vessel damage, blockages, small strokes, and bleeding in the brain can all impair circulation to areas of the brain involved in memory and cognition. Poor brain blood flow is linked to vascular dementia and may also contribute to Alzheimer’s.
An accumulation of unstable, reactive oxygen molecules called free radicals may damage neurons and contribute to Alzheimer’s. Antioxidants help neutralize free radicals, but Alzheimer’s brains have lower antioxidant activity.
Chronic inflammation triggered by things like obesity, diabetes, smoking, and hypertension may set the stage for Alzheimer’s. Anti-inflammatory drugs help manage rheumatoid arthritis and other inflammatory conditions, and may also benefit Alzheimer’s patients.
Insulin plays an important role in brain cell communication and metabolism. Insulin resistance predisposes people to Alzheimer’s, while intranasal insulin improves memory and cognition in Alzheimer’s patients. Restoring insulin’s benefits in the brain could help treat the disease.
Bacterial or viral infections raise overall inflammation levels in the body and brain, increasing Alzheimer’s risk. Herpes simplex virus type 1 in particular has been found in the brains of Alzheimer’s patients and could either trigger or exacerbate disease.
A major head injury increases a person’s risk of eventually developing Alzheimer’s. Trauma causes swelling, bleeding, and scar tissue that damage brain regions involved in memory and cognition. Reducing head trauma may lower Alzheimer’s risk.
In most cases, Alzheimer’s disease results from multiple interacting factors rather than any single cause. Teasing out these relationships and developing targeted treatments remain a major focus in Alzheimer’s research. Now let’s examine how red light therapy can improve Alzheimer’s.

How does Red Light Therapy work for Alzheimer’s?
So how could exposure to light help treat a brain disorder like Alzheimer’s? Red light therapy likely works by activating natural protective mechanisms in cells. Red light can penetrate deep into body tissues where it is absorbed by chromophores – specialized light-sensitive molecules within cells. Chromophores include compounds like cytochrome c oxidase, an important enzyme for cellular energy production. When chromophores absorb red light energy, this triggers signaling pathways that up-regulate protective genes. These genes code for antioxidant enzymes, chaperone proteins, nerve growth factors, and other protective substances.
Through these mechanisms, red light exposure may help Alzheimer’s patients by:
– Improving mitochondrial function and energy supply in neurons
– Reducing oxidative stress and inflammation
– Stimulating nerve cell growth, plasticity, and survival
– Increasing blood flow to enhance oxygen and nutrient delivery
– Improving the brain’s glymphatic waste clearance
Human and animal studies indicate red light therapy boosts levels of key molecules involved in learning and memory. For example, it increases brain-derived neurotrophic factor (BDNF) – a protein crucial for neuron health and synaptic plasticity.
Many researchers believe increasing BDNF and other beneficial factors allows red light therapy to protect vulnerable neurons and restore normal brain function. This may explain why red light therapy shows promise for diverse conditions – from Parkinson’s disease, traumatic brain injury, and depression to stroke, dementia, and Alzheimer’s.

Scientific Evidence on Red Light therapy for Alzheimer’s
While mainstream medicine currently offers no effective Alzheimer’s treatments that slow progression, recent research indicates red light therapy may help stave off damage and improve cognitive function. Here are some of the most promising scientific studies:
For example, in a meta-analysis, analysis showed that red light therapy significantly improved cognitive function in patients with dementia and was a promising non-drug intervention.
Another study found that red light therapy slowed the progression of the neurodegenerative disease and reduced levels of amyloid beta (Aβ) in the cortex, a protein abnormality at the heart of Alzheimer’s disease.
So far, research results are very encouraging. Red light therapy appears capable of protecting neurons from Alzheimer’s-related damage while reviving brain cell function. More large, long-term studies are needed. But red light therapy shows promise as a non-invasive treatment to boost cognition and delay progression in Alzheimer’s patients.
Precautions for red light therapy for Alzheimer’s disease
Red light therapy shows promise for managing Alzheimer’s symptoms, but how do you implement it correctly and safely? Here are some precautions to keep in mind:
– Consult your doctor before starting red light therapy, especially if you are already taking medications for Alzheimer’s. Red light may interact with some medications.
– Start with short sessions and low intensities, then gradually increase over time if tolerated. Going too long or intense too quickly can cause headaches, eye strain or skin irritation.
– Protect your eyes by keeping your eyes closed or wearing protective goggles during treatment. Red light can damage the retina.
– Make sure to use a device that emits light in the wavelength range of 600-1000 nm, which is considered therapeutic for Alzheimer’s. Wavelengths below 600 nm are less effective.
– Position the light source close to but not touching the scalp. Light intensity drops off sharply with distance.
– Treat all major areas of the brain, including the forehead, temples, top and sides of head. Move the device around to cover areas.
– Stay hydrated before and after treatment to avoid light-induced headaches.
– Avoid alcohol and caffeinated beverages prior to treatment which can amplify side effects.
– Limit treatments to a few times per week initially. Too frequent use may cause side effects.
– Monitor for skin irritation, eye discomfort or headaches after treatment. Reduce intensity or duration if these occur.
