Many people are familiar with the common symptoms of Parkinson’s’ Disease, such as uncontrollable tremors. Still, Parkinson’s can also cause a wide variety of other symptoms which may be less familiar. So what causes Parkinson’s, and what are some of the lesser-known symptoms which may help an early diagnosis?
What causes Parkinson’s?
Your body moves in response to signals from the nerves in your brain in the area known as the substantia nigra. The chemical dopamine carries the ‘messages from the nerves to the rest of your body. Parkinson’s Disease is caused when the brain stops producing dopamine, which causes damage to the nerves and interferes with smooth communication. This means that Who can no longer control movement properly.
But Parkinson’s causes a range of other symptoms too, and some of these can show themselves before the characteristic shaking appears, making it possible to form a diagnosis earlier.
The main symptoms
There are three main symptoms of Parkinson’s.
Shaking or tremors in your body is the most common symptom. This usually starts in a small way, such as a slight trembling in your hand when you’re relaxed, but as the illness progresses, it can affect most of your body and can be very debilitating.
Parkinson’s also causes your movements to slow down, so you may find it takes a long time to do everyday tasks such as cooking or cleaning. In addition, patients often develop a shuffling style of walking – sometimes, it feels as though you are ‘stuck to the ground.’
You may also find your muscles stiff, making it difficult and uncomfortable to move around, and sometimes the muscles can go into painful spasms. This stiffness can even affect facial muscles, so people with Parkinson’s may seem to have a blank or distorted face.
Other physical symptoms
Parkinson’s can also cause other physical symptoms. Some patients experience pain in their muscles, and they may have difficulties controlling their bladder or suffer from constipation. Occasionally, muscles can freeze, making movement difficult, while dizziness and eye problems can cause people to fall. Fatigue is also a common symptom and issue with the skin and scalp, such as excessive sweating. If Parkinson’s Disease affects the mouth and throat, this can lead to problems swallowing and sometimes difficulties with speech and communication.
Many people don’t realize that Parkinson’s’ Disease can also cause mental problems, such as anxiety and depression, memory difficulties, and occasional hallucinations and delusions. People with Parkinson’s may also have insomnia, which contributes to feelings of fatigue during the day.
Often the more severe symptoms of Parkinson’s don’t show themselves until the Disease is relatively advanced, but sometimes patients show early signs. For example, losing the ability to smell can indicate the onset of Parkinson’s, and sometimes people begin to use a much quieter voice. If your handwriting becomes smaller, this can be another early sign, or you begin to stoop or become hunched.
How is Parkinson’s diagnosed?
There is no definitive test for Parkinson’s; the Disease is usually diagnosed by looking at the overall combination of symptoms. Most Parkinsons Disease patients won’t have all the symptoms, but especially if the three main symptoms are present, then it’s likely that Parkinson’s will be diagnosed.
How can Parkinson’s be treated?
There is no cure for Parkinson’s. It’s a progressive disease, so symptoms are likely to get worse over time. However, much can be done to help patients manage their symptoms to help them lead as everyday life as possible. Many people manage without needing treatment in the early stages but may need medication to help control symptoms in time.
Physiotherapy can help improve muscle stiffness and pain, and speech therapy can make a significant difference to those whose speech or swallowing is badly affected. Occupational therapy is also an essential aspect of treatment, enabling patients to manage their day-to-day living and maintain a good quality of life. Some patients may even benefit from surgery to manage more extreme problems.
Of course, it’s important to remember that there can be many other causes for all these symptoms. But if you notice two or more of these signs, and they persist for a while without any other explanation, then it’s worth making an appointment to see your family doctor.
