A Closer Look at Multiple Myeloma in Older Adults
Multiple myeloma is a type of blood cancer that typically affects older adults. Because its symptoms can be subtle and mimic other age-related conditions, it is crucial for seniors, their families, and caregivers to be aware of the signs. Myeloma cells accumulate in the bone marrow, interfering with the production of healthy blood cells and causing bone damage. This can lead to the hallmark symptoms often summarized by the acronym CRAB: C - Calcium elevation, R - Renal (kidney) problems, A - Anemia, and B - Bone lesions.
The “CRAB” Symptoms in Detail
C: Hypercalcemia (Elevated Blood Calcium Levels)
As myeloma cells attack the bones, calcium stored in the bones is released into the bloodstream. This can lead to a condition called hypercalcemia, which can cause a range of symptoms in older adults.
- Increased Thirst and Frequent Urination: The kidneys work overtime to filter out the excess calcium, leading to increased fluid intake and urination.
- Fatigue and Weakness: High calcium levels can affect muscle function and energy levels, contributing to a general feeling of tiredness.
- Mental Fogginess and Confusion: Severe hypercalcemia can affect brain function, causing confusion or memory issues that might be mistaken for other cognitive problems.
- Gastrointestinal Issues: Nausea, loss of appetite, and constipation can also occur due to elevated calcium levels.
R: Renal (Kidney) Problems
Multiple myeloma can damage the kidneys, primarily because of the abnormal proteins (M-proteins) produced by the myeloma cells. These proteins can clog the kidneys' filtering system.
- Decreased Urine Output and Swelling: Kidney damage can lead to fluid retention, causing swelling in the legs and ankles.
- Weakness and Fatigue: As kidney function declines, waste products build up in the blood, contributing to fatigue and a general sense of being unwell.
A: Anemia (Low Red Blood Cell Count)
The overgrowth of myeloma cells in the bone marrow crowds out the normal, healthy blood-producing cells, including red blood cells.
- Persistent Fatigue and Weakness: Anemia is one of the most common and earliest signs of myeloma, often manifesting as overwhelming fatigue that doesn't improve with rest.
- Shortness of Breath: With fewer red blood cells to carry oxygen, even light physical exertion can cause shortness of breath.
- Pale Skin: A noticeable pallor can result from the reduced number of red blood cells.
B: Bone Lesions (Bone Pain and Fractures)
Bone pain is a very common symptom, occurring in about two-thirds of multiple myeloma patients.
- Pain: The pain is often described as a deep, aching sensation, most frequently in the back, ribs, and hips.
- Fractures: Weakened bones can fracture easily, sometimes even from minor stress or injury, such as a cough or a simple fall.
- Spinal Cord Compression: If the myeloma weakens the vertebrae, they can collapse and press on the spinal cord, leading to sudden severe back pain, numbness, or muscle weakness, particularly in the legs.
Other Common Symptoms and Complications
Beyond the CRAB criteria, multiple myeloma can cause several other issues that are particularly relevant to older adults.
- Frequent Infections: The disease compromises the immune system, making patients more susceptible to infections like pneumonia, sinus infections, or urinary tract infections.
- Peripheral Neuropathy: Myeloma proteins can damage nerves, causing numbness, tingling, or a 'pins-and-needles' sensation, most often in the hands and feet.
- Hyperviscosity Syndrome: In some cases, a high level of M-proteins can cause the blood to thicken, slowing blood flow. This can lead to confusion, dizziness, and stroke-like symptoms.
- Unexplained Weight Loss: A loss of appetite, often related to other symptoms like nausea or fatigue, can lead to significant weight loss.
Distinguishing Multiple Myeloma from Normal Aging
The challenge in diagnosing multiple myeloma in the elderly lies in the fact that many of its symptoms are also associated with normal aging. For example, fatigue might be attributed to a normal decrease in energy levels, and bone pain might be dismissed as arthritis or osteoporosis. The key difference often lies in the persistence and progression of the symptoms, and the presence of abnormal laboratory test results.
For a proper diagnosis, it is crucial to consult a healthcare provider when persistent symptoms occur. The diagnostic process often involves blood tests, urine tests, and potentially a bone marrow biopsy and imaging scans.
Multiple Myeloma Symptom Comparison
| Symptom | Presentation in Myeloma | Presentation in Normal Aging | Action Recommended |
|---|---|---|---|
| Fatigue | Persistent and profound, not relieved by rest; often linked to anemia. | Mild to moderate, related to exertion or poor sleep; improves with rest. | Consult a doctor for blood work if fatigue is severe and persistent. |
| Bone Pain | Aching, persistent pain, especially in the back, hips, or ribs; may worsen with activity. | Generalized, mild aches and stiffness, often related to arthritis. | Investigate persistent, localized pain, especially if it worsens or is severe. |
| Infections | Frequent, recurrent infections (e.g., pneumonia, UTI) that are hard to treat. | Occasional infections, often manageable with standard treatments. | Report recurrent or severe infections to a healthcare provider. |
| Cognitive Changes | Can be abrupt, with confusion or mental fogginess due to high blood calcium. | Gradual decline in memory or processing speed; varies significantly. | Seek immediate medical evaluation for sudden cognitive changes. |
| Weight Loss | Unexplained and significant weight loss over a short period. | Gradual, often slight, weight changes possibly related to appetite shifts. | Discuss any unintentional, rapid weight loss with a doctor. |
Conclusion: The Importance of Early Recognition
Multiple myeloma can present a diagnostic challenge in the elderly due to its insidious onset and resemblance to other conditions. However, recognizing the patterns of symptoms, particularly the combination of persistent fatigue, bone pain, and frequent infections, is critical. Early and accurate diagnosis is essential for receiving timely and effective treatment, which can significantly improve an individual's quality of life and prognosis. Anyone concerned about these symptoms, whether for themselves or a loved one, should seek a medical evaluation.

How Family and Caregivers Can Help
Family members and caregivers play an essential role in recognizing and reporting symptoms. Because an elderly person may downplay persistent discomfort or forget to mention certain symptoms, a caregiver's objective observation is invaluable. Maintaining a log of symptoms, such as the location and severity of pain, fatigue levels, and any changes in appetite or mood, can provide a doctor with a clearer picture of the situation. Advocating for a full workup and asking direct questions about multiple myeloma during appointments can also help ensure the disease is not overlooked.
