Parkinson’s disease is a condition that affects the brain and gradually slows down how the body moves. It often causes tremors, stiffness, balance issues and difficulty with everyday activities. While the exact cause is not fully known and some cases run in families, the good news is that there are ways to lower the risk and support brain health. This article will take a closer look at some practical ways to help prevent Parkinson’s disease.
What is Parkinson’s disease?
Parkinson's disease is a condition that affects the control of movement and is caused by dying nerve cells in the brain, particularly those responsible for producing dopamine. Dopamine plays a role in facilitating coordinated muscle movements, so when its levels are low, it leads to the characteristic symptoms of Parkinson’s disease, such as tremors, rigidity and slowness of movement.
As the disease progresses, individuals may also experience non-motor symptoms like cognitive changes and mood disorders. While there is currently no cure for Parkinson's disease, various treatments and therapies aim to manage symptoms and improve quality of life for those living with the condition.
Early symptoms of Parkinson’s disease
Parkinson’s disease begins with mild signs that gradually worsen over time. Recognising these early symptoms can help in timely diagnosis and better management of the condition:
- Shaking: Noticeable shaking or tremor in the hand, fingers, chin or lip.
- Reduced spontaneous movements: Patients may exhibit fewer facial expressions, blink less and sway their arms less when walking.
- Rigid muscles: Muscles may feel tense, stiff or painful, and movements can become jerky or restricted.
- Poor posture and balance: Stooped posture, frequent falls or difficulty maintaining balance.
- Writing: Handwriting may become unusually small and cramped, a condition known as micrographia.
- Non-motor symptoms: Depression, anxiety, constipation, sleep issues, frequent urination, reduced sense of smell, memory problems and fatigue.
Ways to prevent Parkinson’s disease
Preventing Parkinson's disease is an evolving area of research. However, certain lifestyle choices and habits may contribute to reducing the risk. Here are some of the most effective strategies that can support brain health and prevent Parkinson’s disease:
1. Choose organic (and local)
Opting for organic produce can help minimise exposure to pesticides and herbicides, which studies suggest could be linked to an increased risk of Parkinson’s disease. Organic farming methods generally avoid using synthetic pesticides. By exploring local farmers’ markets, you can find fruits and vegetables that are grown locally while supporting your community at the same time.
2. Eat fresh and raw vegetables
Fresh, uncooked vegetables contain levels of antioxidants like vitamins C and E. These antioxidants play a role in combating stress in the body, which is linked to various neurodegenerative conditions such as Parkinson's disease. Raw vegetables are packed with essential nutrients that support overall health and help the body function properly.
3. Incorporate omega-3 fatty acids into your diet
Including sources of omega-3 acids like fish (such as salmon), flaxseeds and walnuts can be beneficial for brain health. These healthy fats have been associated with properties that may reduce the risk of Parkinson’s disease.
4. Getting vitamin D3
It's important to get sunlight exposure in the morning hours as sunlight helps the skin produce vitamin D. Maintaining adequate levels of vitamin D has been linked to a lower risk of Parkinson's disease.
5. Diet and supplements
Make sure your diet includes vitamin-rich food, like fortified dairy products and fatty fish. If needed, consult healthcare professionals about taking vitamin D supplements to meet recommended levels.
6. Green tea
Green tea contains polyphenols, mainly epigallocatechin gallate (EGCG), which possess antioxidant and anti-inflammatory properties. Regularly consuming green tea may offer advantages, potentially reducing the likelihood of developing neurodegenerative disorders.
7. Adequate sleep
Getting quality sleep is crucial for maintaining the brain’s health and optimal functionality. It is recommended to aim for 7-9 hours of sleep per night, as sleep disturbances have been associated with an increased risk of diseases.
8. Mental and social stimulation
Engaging in socially interactive activities can contribute to the resilience of the brain. Activities like reading, solving puzzles or participating in social interactions can support cognitive health and make the brain more resistant to Parkinson’s disease.
9. Aerobic exercise
Regularly participating in aerobic exercise has been linked to a decreased risk of Parkinson's disease. Exercise promotes overall well-being, triggers the release of brain-derived neurotrophic factor (BDNF) and supports the growth and survival of neurons.
10. Coenzyme Q10
CoQ10 acts as an antioxidant involved in cellular energy production. While further research is necessary, some studies suggest that supplementing with CoQ10 may have neuroprotective effects, potentially benefiting those at risk of Parkinson's disease.
Treatment options for Parkinson’s disease
There is currently no cure for Parkinson’s disease, but treatment can help control symptoms and support a better quality of life. Therapies such as physiotherapy, occupational therapy and speech therapy play an important role, as they make daily tasks easier and improve movement, communication, swallowing and digestion.
Medicines are the main line of treatment. The most common include levodopa combined with carbidopa or benserazide. Other options may involve dopamine agonists, monoamine oxidase B (MAO-B) inhibitors and catechol-O-methyltransferase (COMT) inhibitors.
For people with more advanced symptoms, advanced treatments such as deep brain stimulation (DBS) or infusion pumps may also be considered.
Health insurance coverage for Parkinson’s treatment
Treating Parkinson’s disease often requires long-term treatment, which can include drug therapy, physiotherapy and sometimes surgery, such as deep brain stimulation. These treatments can lead to significant expenses for patients and their families.
Taking preventive steps and securing a health insurance policy that covers hospitalisation, doctor consultations, medicines and treatment for Parkinson’s disease can help reduce both financial burden and stress.
Conclusion
Although Parkinson’s disease cannot be fully prevented, certain lifestyle choices such as staying physically active, following a healthy diet and seeking timely medical care may help slow or ease its symptoms. In such cases, a reliable health insurance policy can provide a financial safeguard.
Depending on your medical needs, you can choose different plans, like critical illness insurance or individual health insurance. If you are not sure which plan suits your needs best, fill out the form on this page to receive expert guidance.
