Can Huntington’s disease (HD) cause dementia? It may also affect your ability to perform everyday activities such as driving. Chorea can make speaking, eating and walking more difficult. Later, it also makes your arms, legs and torso move uncontrollably. Chorea usually affects hands, fingers and face muscles first. One of the first physical symptoms of HD is chorea, unintended jerks or twisting movements. Loss of hand coordination, such as being unable to hold a pencil.Problems with memory, focus and multitasking.Emotional changes like mood swings, depression and irritability.Physical problems may start in small ways - for example, clumsiness or losing balance - and then get worse over time. HD affects a person both physically and mentally. What are the symptoms of Huntington's disease (HD)? This part of the brain helps with thinking, decision-making and memory. The disease also impacts the brain’s cortex (surface of the brain). First, they usually attack the basal ganglia, an area in the brain that oversees the body movements you control. Huntington’s disease develops when misshapen proteins destroy neurons (brain cells). How does Huntington’s disease (HD) affect the brain? Often, HD symptoms start earlier in each new generation than in the previous generation. The exact age when symptoms appear varies. Anyone who inherits the gene will eventually develop HD symptoms.Researchers believe this long protein damages and kills brain cells. It tells your body to create an unusually long protein. If you have Huntington’s disease, one of your parents passed on an HTT gene with a mutation (like a misprint in a book).

The huntingtin gene (HTT or HD gene) tells your body how to build the huntingtin protein.

Here’s how genes affect Huntington’s disease: Genes are like “chapters” within the DNA instruction manual. Your DNA dictates everything from your hair color and height to how your organs function. It provides the information you need to repair and rebuild cells. To understand how HD is inherited, you have to know a little bit about genetics - the study of physical characteristics passed down from generation to generation.Įvery cell in your body has DNA (deoxyribonucleic acid). How is Huntington's disease (HD) inherited? Juvenile Huntington’s disease is even less common - children make up 5% to 10% of HD cases. In North America, the prevalence of HD was 5.7 per 100,000 people. HD is rare, affecting about 30,000 Americans. Children with JHD most often inherit the disease from their fathers. In addition to the symptoms of the adult disease, early signs in children may include seizures and stiffness. But with juvenile Huntington’s disease (JHD), symptoms begin in childhood. Typically, HD symptoms appear in middle age. What is juvenile Huntington’s disease (HD)? If you do, you have a 50% chance of also having the disease. But the main factor is whether you have a parent with HD. Who does Huntington's disease (HD) affect?Īlthough anyone can develop HD, it tends to run in people of European descent (having family members who came from Europe).

It’s also common to have changes in emotion (feelings) and thinking, such as mood swings and memory problems. They eventually affect walking, talking and swallowing. It attacks the brain, causing unsteady and uncontrollable movements (chorea) in the hands, feet and face. Huntington's disease (HD) is a genetic disease that’s passed from parent to child.
