Unraveling the Devastation: Huntington Disease’s Symptoms and Progression

Huntington disease: Understanding the Symptoms and ProgressionImagine waking up one day and finding that your body is no longer under your control. Your limbs flail out wildly, and your speech becomes slurred and unintelligible.

This nightmare is a reality for those suffering from Huntington disease, a devastating brain disorder that affects their neurons and leads to a wide range of symptoms. In this article, we will explore the various aspects of Huntington disease, from its definition and causes to its symptoms and subtypes.

1) Definition and Symptoms:

Huntington disease is a genetic disorder that causes the progressive degeneration of brain cells, particularly in the areas responsible for movement and coordination. This degeneration leads to a host of symptoms, including emotional disturbances, intellectual abilities, and uncontrolled movements.

These symptoms typically appear in mid-adult life, but they can also manifest earlier in some cases. 2) Subtypes:

There are two main subtypes of Huntington disease: adult-onset Huntington disease and early-onset Huntington disease.

Adult-onset Huntington disease is the most common form and usually develops between the ages of 30 and 50. Early-onset Huntington disease, on the other hand, occurs before the age of 20 and is less common but usually progresses faster.

3) Causes:

Huntington disease is a genetic disorder that is caused by a mutation in the huntingtin gene. This mutation leads to the production of an abnormal form of the huntingtin protein, which then accumulates in the brain cells and causes their degeneration.

The inheritance of the mutated gene follows an autosomal dominant pattern, meaning that a child has a 50% chance of inheriting the disease if one of their parents carries the mutation. 4) Diagnosis:

Diagnosing Huntington disease is a complex process that involves a combination of physical and neurological exams, blood tests, and brain imaging scans.

During the physical and neurological exam, the doctor will look for signs of uncontrolled movements, changes in coordination, and other characteristic symptoms of the disease. Blood tests can also be used to detect the presence of the mutated huntingtin gene.

Additionally, brain imaging scans like CT, MRI, and PET scans can provide detailed images of the brain and help detect any abnormalities. 5) Risk factors:

The most significant risk factor for developing Huntington disease is inheriting the mutated huntingtin gene.

However, the age of onset can vary from person to person, and the rarity of the disease further adds to its complexity. It is important to note that having a family history of Huntington disease does not necessarily mean that an individual will develop the disease, as some cases occur spontaneously due to new mutations in the huntingtin gene.

Understanding the Symptoms:

1. Early symptoms:

In the early stages of Huntington disease, individuals may experience irritability, depression, and mood swings.

They may also have trouble driving, trouble learning new information, and difficulty making decisions. As the disease progresses, they may start forgetting facts and become increasingly dependent on others for daily activities.

2. Progressive symptoms:

As the disease advances, individuals with Huntington disease may have trouble feeding themselves and experience difficulty swallowing.

They may develop strange and uncontrolled movements, such as jerking or dancing-like motions. These movements, known as chorea, are often a characteristic feature of the disease.

Loss of memory and judgment, changes in speech, and personality changes are also common. Disorientation, hallucinations, paranoia, and even psychosis can occur in later stages of the disease.

3. Symptoms in children:

While Huntington disease is commonly associated with adult-onset, there is also a form that affects children.

Children with Huntington disease may display Parkinson’s disease-like features, such as slow movements, rigidity, and tremors. They may also experience difficulties with balance and coordination, making it challenging for them to perform fine motor tasks.


Huntington disease is a debilitating brain disorder that affects individuals and their families in profound ways. By understanding its symptoms and progression, we can support those affected and promote research towards finding effective treatments and, eventually, a cure.

In conclusion, Huntington disease is a genetic brain disorder that causes the progressive degeneration of neurons, resulting in a range of symptoms such as emotional disturbances, loss of intellectual abilities, and uncontrolled movements. It can manifest in two main subtypes: adult-onset and early-onset.

The disease is caused by a mutation in the huntingtin gene and is typically inherited from a parent. Diagnosis requires a combination of physical and neurological exams, blood tests, and brain imaging scans.

Early symptoms include irritability, mood swings, and difficulty driving and learning, while progressive symptoms may involve trouble feeding oneself, abnormal movements, and changes in memory and personality. In some cases, children may display Parkinson’s disease-like features.

While Huntington disease is a devastating diagnosis, understanding its symptoms and progression is vital to supporting those affected and promoting further research.
