What are the symptoms of chorea?
The most common movement symptom is chorea, which is characterized by abrupt, jerky, irregular, and unpredictable movements. Behavioral and psychiatric symptoms include depression, anxiety, irritability, apathy, impulsivity, and obsessive tendencies. And the disease often leads to cognitive decline and dementia.
When did Sarah Foster first know something was wrong?
Researchers are pursuing therapies that may alter the course of this inherited neurodegenerative condition. Sarah Foster first knew something was wrong in 2005 when she kept forgetting she had an infant. "He would be asleep in the other room, and I would suddenly realize, 'Oh my gosh, I have a son,'" says Foster, then 39. ...
Does Jennifer Foster have a memory disorder?
Foster has been relatively untouched by the movement symptoms of HD, but she has struggled with cognitive deficits, including memory lapses and behavioral changes. "Right now I'm having trouble with compulsive behaviors, particularly shopping and eating, that I'm working on with my psychiatrist," she says.
Is there a cure for HD?
Ongoing studies are looking for additional genes that influence the course of HD, among other characteristics of the disease, he says. Although there is no cure, the outlook for patients has brightened in recent years. "Currently no treatments slow the progression," says Dr. Bang.
Does huntingtin cause HD?
Bang. "But the mutant form, which occurs when one has the mutant huntingtin gene, is harmful to many of the brain cell functions and is thought to be the main cause of HD symptoms."
Is HD a progressive disease?
HD, a progressive and fatal disease, "causes a triad of symptoms—motor, psychiatric, and cognitive," says Erin Furr-Stimming, MD, associate professor of neurology at the University of Texas Health Science Center McGovern Medical School in Houston. "Most individuals become symptomatic in their forties, during the prime of their life, after which the symptoms continue to worsen, robbing them of their ability to walk, talk, and live independently."
How old do you have to be to get Huntington's disease?
Onset of Huntington’s disease typically occurs between the ages of 30 and 50. While symptoms can be treated to an extent, there is no known cure, and the disease is ultimately fatal. Around 30,000 Americans have the disease, which is inherited. People with the genetic abnormality have a 50-50 chance of developing Huntington’s.
