Description

Cognitive decline, including symptoms of memory loss and dementia, can have a variety of underlying causes. Some of these causes are treatable, and identifying them early is crucial to managing or even reversing the condition. The Memory/Dementia Advanced Blood Panel is designed to help healthcare providers evaluate several potential causes of cognitive decline, including common conditions like anemia and hypothyroidism, as well as less common causes like heavy metal exposure, hyperparathyroidism, and HIV.

When to Consider This Panel:

This test is recommended for individuals experiencing:

  • Memory problems or cognitive decline
  • Difficulty with concentration or thought processing
  • Changes in mood, personality, or behavior
  • Symptoms that may suggest underlying medical conditions contributing to cognitive issues

Included Biomarkers and Their Clinical Relevance:

Apolipoprotein E (APOE) Genotyping

  • What it measures: Genetic testing to determine the presence of the APOE gene, which can affect the risk of Alzheimer’s disease and other dementias.
  • Why it matters: APOE ε4 allele is a known risk factor for Alzheimer's disease and cognitive decline.

Complete Blood Count (CBC)

  • What it measures: The number and health of red and white blood cells, platelets, hemoglobin, and hematocrit.
  • Why it matters: Can identify anemia or infection, which may contribute to cognitive impairment or fatigue.

Comprehensive Metabolic Panel (CMP)

  • What it measures: Kidney and liver function, electrolyte levels, glucose, and calcium.
  • Why it matters: Abnormal metabolic function or electrolyte imbalances can affect brain function and contribute to cognitive issues.

Heavy Metals

  • What it measures: Levels of toxic metals like lead, mercury, and arsenic.
  • Why it matters: Chronic heavy metal exposure can lead to neurological damage, memory problems, and cognitive decline.

High-Sensitivity C-Reactive Protein (hs-CRP)

  • What it measures: An inflammatory marker in the blood.
  • Why it matters: Chronic inflammation has been linked to cognitive decline and diseases like Alzheimer’s and dementia.

HIV

  • What it measures: Presence of HIV antibodies and antigens.
  • Why it matters: HIV infection can contribute to cognitive decline (HIV-associated neurocognitive disorder, or HAND), and early detection can help in the management of cognitive symptoms.

Prolactin

  • What it measures: A hormone involved in the reproductive system and various body functions.
  • Why it matters: Abnormal prolactin levels may affect cognitive function and signal underlying pituitary or hormonal issues.

Rapid Plasma Reagin (RPR)

  • What it measures: A screening test for syphilis.
  • Why it matters: Neurological syphilis can present as cognitive decline, and early detection is important for effective treatment.

Thyroid Stimulating Hormone (TSH)

  • What it measures: A hormone that regulates thyroid function.
  • Why it matters: Hypothyroidism is a common cause of cognitive impairment and memory problems, especially in older adults.

Vitamin B12 and Folate

  • What it measures: Levels of vitamin B12 and folate in the blood.
  • Why it matters: Deficiencies in B12 and folate can cause memory problems, confusion, and other cognitive issues, which are reversible with supplementation.

Fasting Requirements:

  • Fasting is not required for this blood panel.

Summary:

The Memory/Dementia Advanced Blood Panel is a comprehensive test designed to evaluate multiple biomarkers that can contribute to cognitive decline and memory issues. By testing for common causes such as hypothyroidism, anemia, and vitamin deficiencies, as well as less common but treatable causes like heavy metal exposure and HIV, this panel provides a broad picture of potential underlying conditions. Identifying and addressing these conditions early can help slow or even reverse cognitive decline, improving overall quality of life.

If you're experiencing symptoms of cognitive decline, consider discussing this panel with your healthcare provider to help rule out treatable causes and develop an appropriate treatment plan.
