Parkinson's Disease Can Remain Hidden For A Decade – How To Spot The Early Signs

Parkinson's disease often begins with subtle symptoms such as hand tremors or shaking. Many people may recall seeing this in action during the Barcelona Olympics, where boxing legend Muhammad Ali struggled with a trembling hand while lighting the Olympic torch. Ali was a well-known Parkinson's patient, and tremors are one of the most recognizable signs of the condition. Other early signs include muscle stiffness or a noticeable reduction in movement. In my clinical experience, many patients later recall early difficulties such as trouble mounting a bicycle with one leg or being unable to walk normally without dragging a foot. Sometimes, family members or friends are the first to notice these changes, such as hearing a shuffling sound when the person walks.

Why Parkinson's Can Be Difficult To Detect Early

The progression of Parkinson's disease can be extremely gradual, with some individuals living with symptoms for over a decade before receiving a proper diagnosis. This delay is largely due to the fact that early symptoms are often mistaken for signs of aging or unrelated conditions. Common early indicators include constipation, reduced sense of smell, changes in posture, and limb rigidity. Unfortunately, many people experiencing these symptoms either dismiss them or seek care in unrelated specialties like orthopedics, where imaging tests often show no abnormalities, leading to missed opportunities for early detection.

Key Symptoms That Should Not Be Ignored

Non-Motor Symptoms Worth Watching

Changes in bowel habits, particularly persistent constipation, and loss of smell are often overlooked but can be early signs of Parkinson's. Additionally, subtle changes in the way someone walks—like a shuffling gait or decreased arm swing—can indicate the onset of the disease. These symptoms, while mild at first, should prompt further investigation if they persist or worsen over time.

When To Seek Specialized Medical Help

If you or a loved one experiences these early symptoms and standard evaluations in other medical fields—such as orthopedics—rule out other causes like back pain or joint issues, it's crucial to consult a specialist in movement disorders. A neurologist or a Parkinson's disease specialist at a dedicated Parkinson's clinic can perform a thorough assessment and determine if further testing or treatment is needed.
