What is Parkinson’s disease? 

Parkinson’s disease is a progressive neurological condition. This means that is a condition where parts of the brain become damaged over time.  

Symptoms 

There are several different symptoms that are common amongst those with Parkinson’s disease. These are grouped into 3 distinctive categories which include the 3 main symptoms, physical symptoms and mental symptoms.  

The 3 main symptoms affect someone with Parkinson’s disease in the following ways: 

Physical symptoms: 

Mental symptoms: 

When looking at a person’s symptoms it is important to remember that they will be different for each individual. The severity of these symptoms, the order that they appear and the way in which they progress will also vary from one individual to another.  

Causes 

Parkinson’s disease develops due to a loss of nerve cells in the section of the brain that is called the substantia nigra. These nerve cells are responsible for producing a neurotransmitter called dopamine. Our body uses dopamine to send chemical messages between parts of the brain and the nervous system. This helps to co-ordinate and control our bodies movements. When these nerve cells die it results in an impairment in the brains ability to control our movement. This means that our movements become disrupted and slower. As these dopamine levels continue to fall over time it causes the symptoms to both develop further and make new ones appear.  

Research that has aimed to find out why the loss of these nerve cells has been linked with Parkinson’s disease is still inconclusive. However, it is believed that a combination of environmental and genetic factors may increase the chances of its development.  

Genetics 

There are a small number of rare cases where it is has been reported that Parkinson’s has been passed down from a parent to their children. 

Environmental factors 

There are some researchers who believe that environmental factors may increase the risk of someone developing Parkinson’s disease. These factors include exposure to pesticides, herbicides, toxic chemical and pathogens.  

Diagnosis 

Before getting a diagnosis, a specialist will want to ask you questions about your symptoms, put you through a medical examination and look at your medical history. This is because diagnosing someone with Parkinson’s is not an easy thing to do as there are other conditions they may want to rule out. Depending on how severe the symptoms are a specialist may prescribe you a medication called levodopa. This is so that if the symptoms improve after taking it for a period of time the specialist may be able to confirm the diagnosis of Parkinson’s.  

It may be beneficial to take someone with you to this appointment for support. It could also help to make a list of any questions you may have and any further information you would like.    

Treatment  

At this moment in time there is no cure for Parkinson’s disease. However, there are several types of treatments that are available to help alleviate some of the symptoms. This will allow you to live your life as close to normal as possible. These treatments can include forms of supportive therapies and medication.  

Supportive therapies 

There are three types of supportive therapies that you can be referred to, such as: 

These therapies are completely individualistic as each one of them will appeal to a different person. Therefore, it is important to try them out and find what works best for you.  

Medication 

Medication can be taken to improve some of the symptoms of Parkinson’s disease. However, before it gets to this stage it is vital to sit down with a specialist so they can explain all of the options that are on the table as well as the risks of taking each. This will allow you to weigh up the risks alongside the benefits to find what may be best for you. 

The three main prescribed medications would be: 

Levodopa 

Levodopa is absorbed by nerve cells in your brain and turned into dopamine. The use of this medication will improve several of the symptoms of Parkinson’s such as a slowing down in movement and stiffness.  

Side effects include: 

Dopamine agonist 

They work by acting as a replacement for dopamine in the brain. This is because they are able to trick the brain into thinking that they are dopamine. By mimicking the way it works it can help to reduce the symptoms.  

Side effects can include: 

MOA-B inhibitor 

These inhibitors work by blocking the breakdown of dopamine in the brain. This means that there is more dopamine available to treat the symptoms.  

Side effects: 

Impact on mental health 

Someone with Parkinson’s can experience a wide range of mental health issues alongside their symptoms. These can include memory problems, depression and anxiety, to name a few. One of the reasons for their development can be due to feelings of concern, worry and fear that come with being made aware that you will have to live with a long-term condition. In addition to this, when the symptoms begin to progress, some may start to limit their time socialising with others. This can lead to feelings of loneliness and becoming more isolated which can increase the chances of depression. 

These mental health issues can be addressed in several different ways including:
