Parkinson’s Disease: What It Is, Causes, Symptoms & Treatment

Some research has shown that regular aerobic exercise might reduce the risk of Parkinson’s disease. Because the cause of Parkinson’s is unknown, there are no proven ways to prevent the disease. Parkinson’s disease is not contagious, and you can’t contract it from another person. Here’s what you need to know about the condition and what you should consider if a relative has Parkinson’s disease.

With nowhere to go, the proteins build up in various places or in certain cells (tangles or clumps of these proteins are called Lewy bodies). The buildup of these Lewy bodies (which doesn’t happen with some of the genetic problems that cause Parkinson’s disease) causes toxic effects and cell damage. A genetic mutation is just one of several risk factors for Parkinson’s disease. In fact, most people with Parkinson’s disease are unaware of any other family member with the condition, according to the National Human Genome Research Institute (NHGRI). Studies have found different genes linked to Parkinson’s disease in different patterns of inheritance.

That’s why lack of dopamine causes the slowed movements and tremors symptoms of Parkinson’s disease. Understanding the connection between Parkinson’s and genetics can help us understand how the disease develops and ultimately these details how it can be treated or cured. Symptoms may start in one side of the body but move to other parts in time. Some people will only ever develop mild symptoms, while others may become unable to take care of themselves.

Under normal circumstances, your brain uses chemicals known as neurotransmitters to control how your brain cells (neurons) communicate with each other. When you have Parkinson’s disease, you don’t have enough dopamine, one of the most important neurotransmitters. “You’re susceptible, but you need something else present, as well [to develop the disease],” explained Dr. Litvan. “That could be other genes, or it could be an environmental factor.” Other factors, such as toxin exposure and head injuries, also appear to play a role.

Identifying your genetic mutations can help you determine if you are eligible to enroll in certain clinical trials. Several ongoing clinical trials are already testing treatments for people who carry certain read what he said PD gene mutations in LRRK2 and GBA. If you have a family member with Parkinson’s disease, you may want to consider genetic testing. Having a gene mutation doesn’t guarantee that you’ll get the disease.

In years past, experts believed non-motor symptoms were risk factors for this disease when seen before motor symptoms. However, there’s a growing amount of evidence that these symptoms can appear in the earliest stages of the disease. these details That means these symptoms might be warning signs that start years or even decades before motor symptoms. Parkinson’s disease is an age-related degenerative brain condition, meaning it causes parts of your brain to deteriorate.
