For families and caregivers, understanding the differences between Huntington’s and Parkinson’s disease can make a significant impact on care decisions and expectations. Both of these conditions affect the central nervous system and are progressive, but they have distinct causes, symptoms, and treatments. Here, we’ll explain the key aspects of Huntington’s vs. Parkinson’s to support families seeking clarity and resources.
What Is Huntington’s Disease?
Huntington’s disease is an inherited disorder caused by a genetic mutation in the huntingtin (HTT) gene. If a parent has this mutated gene, they have a 50% chance of passing it on to their child. Huntington’s usually starts between the ages of 30 and 55, though some cases begin earlier or later. The condition leads to the breakdown of nerve cells in the brain, affecting movement, thinking, and mood. This progressive loss of brain function typically shortens the lifespan, with symptoms worsening over time.
Huntington’s is unique in its genetic nature. Because it is caused by a single gene, those who inherit the mutated gene are certain to develop the disease at some point. Symptoms often begin subtly, affecting coordination and leading to involuntary movements known as chorea.
What Is Parkinson’s Disease?
Parkinson’s disease is the second most common neurodegenerative disorder in the United States after Alzheimer’s. Unlike Huntington’s, Parkinson’s is not directly inherited and typically begins after age 60. The cause of Parkinson’s is generally unknown, though researchers believe it may result from a combination of genetic and environmental factors. Parkinson’s disease involves a loss of dopamine-producing cells in a specific area of the brain called the substantia nigra, which plays a key role in motor control.
Symptoms of Parkinson’s may start as a slight tremor or slowness of movement, known as bradykinesia, and progress gradually over time. Other common symptoms include muscle stiffness, balance issues, and changes in walking. As dopamine levels continue to decrease, these symptoms become more pronounced, affecting daily activities and quality of life. While there is no cure for Parkinson’s, medications and therapies can help manage symptoms and improve motor function.
Different Causes And Genetic Factors
The primary distinction between these two diseases lies in their causes. Huntington’s is directly inherited through a mutation in the HTT gene, meaning it runs in families and can be diagnosed with a genetic test. If a person carries the gene, they will develop the disease at some point, making it a predictable genetic condition.
Parkinson’s disease, on the other hand, is known as idiopathic, which means its cause is often unknown. Some cases of Parkinson’s have been linked to specific genetic mutations, but not all individuals with these mutations develop the disease.
Unique Symptoms Of Each Condition
While both Huntington’s and Parkinson’s affect movement and cause involuntary motions, the types of movements and symptoms differ. Huntington’s often leads to chorea, which causes jerking or writhing movements that may appear dance-like and affect the arms, legs, face, and torso. This disease also significantly impacts mood and thinking, leading to personality changes, depression, and challenges with concentration and decision-making. In later stages, individuals with Huntington’s may struggle with swallowing and other basic motor functions, making daily care more complex.
In Parkinson’s, the symptoms often begin with a rhythmic tremor, particularly in the hands, and a general slowing down of movements. This slowing, or bradykinesia, can make simple activities more difficult, as people with Parkinson’s may experience stiffness and a limited range of motion. Parkinson’s also impacts balance and posture, increasing the risk of falls. Mood changes and cognitive decline can occur in Parkinson’s, but they are generally less pronounced than in Huntington’s, though each case can vary.
Approaches To Diagnosis
Diagnosing Huntington’s and Parkinson’s can be challenging, and the processes vary for each. Huntington’s can be confirmed through a genetic test that looks for the mutation in the HTT gene. When a family history of Huntington’s is present, this test can confirm whether a person will develop the disease, even before symptoms appear. Some people may choose genetic counseling to understand the impact and implications of testing, as Huntington’s is a lifelong and progressive condition.
For Parkinson’s, there is no single test to confirm the diagnosis. A diagnosis typically involves a physical examination, a review of medical history, and observation of symptoms over time. Doctors may order imaging tests like MRI or CT scans to rule out other conditions. Blood tests may also be conducted to exclude other causes of symptoms.
