Welcome To A New Frontier In Understanding Alzheimer’s

Alzheimer’s LINX™ is the result of years of research in environmental factors that are known to have an association with the development of Alzheimer’s disease.

  • 1 In 10 People Age 65 And Older Has Alzheimer’s Disease.
  • Almost two-thirds of Americans with Alzheimer’s are women.
  • According to the Alzheimer’s association, 5.8 million Americans are living with Alzheimer’s. By 2050, this number is projected to rise to nearly 14 million. Today, 1 in 3 seniors die with Alzheimer’s or other dementia.

Alzheimer’s-Associated Immune Reactivity | Alzheimer’s LINX Lab Test

An important aspect of Alzheimer’s disease that is highly overlooked is the breakdown of the blood-brain barrier (BBB).

The blood-brain barrier is a highly selective barrier between blood vessels and neurons. Its job is to let good things in and keep bad things out.

When this barrier is damaged by things like microbes, chemicals, heavy metals, food sensitivities, etc., the factors that keep the BBB healthy starts to diminish which can increase neuro-inflammation leading to cognitive decline.

The new Cyrex Alzheimer’s blood test (LINX) looks for antibodies to damaging BBB factors and checks to see if the immune system is attacking factors that keep the brain healthy.

The results of this test can help you and your healthcare practitioner develop a plan to help restore the blood-brain barrier and promote a better brain for those with cognitive decline and those who may have a genetic susceptibility for Alzheimer’s.

The Cyrex LINX Alzheimer’s blood test is also useful for those:

  • Interested in preventing Alzheimer’s disease.
  • Who are exhibiting early signs of Alzheimer’s.
  • Have been diagnosed with Alzheimers’s.
  • Who have a history of gut disorders and/or diabetes.
  • Who played high-impact sports.
  • Who have multiple food and chemical senstivites.

Window Of Opportunity For Intervention

Pathological changes of Alzheimer’s from normal, are classified into three major stages.

  • Preclinical
  • Mild Cognitive Impairment
  • Dementia
Alzheimer's LINX™ Testing

The Power of Predictive Antibodies
Identifying root causes in the earliest stages possible is crucial for developing interventional programs.
Detect antibodies up to 20 years before symptoms actually appear!


Alzheimer’s Disease And Environmental Factors Alzheimer’s LINX assess/measures immune reactivity to the following groups of key contributing factors:

  1. BRAIN PROTEINS – brain proteins beyond amyloid-beta and tau
  2. GROWTH FACTORS – factors involved in neuronal regeneration
  3. ENTERIC NERVE, ENZYMES AND NEUROLOGICAL PEPTIDES – the communication pathway between the gut and the brain
  4. PATHOGENS – known to cross-react with amyloid-beta
  5. CHEMICALS – Biomarkers for a collection of chemicals/heavy metals discovered to have associations to Alzheimer’s
  6. FOOD THAT CROSS-REACT WITH AMYLOID-BETA – Eight out of 208 foods, newly discovered to have the potential association with Alzheimer’s
  7. BLOOD-BRAIN BARRIER AND NEUROFILAMENTS – Assesses the integrity of the blood-brain barrier

 Clinical Use

  • To identify patients at greater risk for developing Alzheimer’s disease or other neurological disorder.
  • To identify reactivity to triggers of Alzheimer’s disease or other neurological disorder.
  • To identify the early stage of neurodegenerative processes.
  • To monitor the effectiveness of lifestyle modifications for Alzheimer’s disease.
  • This test does not diagnose alzheimers diseases

Recommended for Patients Who

  • Are interested in preventing the development of Alzheimer’s disease or other neurological disorder.
  • Are exhibiting early signs of Alzheimer’s disease or other neurological disorder.
  • Have been diagnosed with Alzheimer’s disease.
  • Have a history of gastrointestinal disorders and/or diabetes.
  • Played high-impact sports.
  • Are immunoreactive against specific pathogens, chemicals and foods.
