It's normal to feel a lot of fear and anxiety when your doctor tells you that someone in your family, perhaps your beloved mother or father, has Parkinson's Disease. Although there is still no cure for this disease, there are many effective medications that can help control the symptoms and maintain a good quality of life. So today, let's talk about what these medications are, how they work, and what we need to be aware of.
Why does Parkinson's disease occur? What happens with medication?
Simply put, Parkinson's disease is a progressive neurological condition that affects the body's movements. It is caused by the gradual loss of nerve cells in the brain, especially in the part of the brain called the substantia nigra that controls movement. These nerve cells produce a neurotransmitter called dopamine .
Think about it, a chemical called dopamine is essential for our body to move smoothly, like driving on a road without traffic jams. In Parkinson's disease, the production of this dopamine decreases, resulting in symptoms such as slow movements, tremors, and stiffness.
So the main goal of many medications for Parkinson's disease is to somehow control the low levels of dopamine in the brain.
Mainly used medicines
Doctors usually prescribe a combination of several medications for Parkinson's patients, not just one. Let's take a look at the main types of medications.
| Drug Class | How it Works | Important information |
|---|---|---|
| Levodopa and Carbidopa | Levodopa is a drug that goes to the brain and turns into dopamine. But because it is destroyed in the body before it reaches the brain, it is combined with a drug called carbidopa to stop it. | This is the main and most effective medication for Parkinson's disease. It is very effective in reducing slowness of movement (bradykinesia), rigidity, and tremors. |
| Dopamine Agonists | These stimulate dopamine receptors in the brain and "act" like dopamine. That is, these drugs do the same thing that dopamine does. | Often used in the early stages of the disease or in younger patients, it also helps to maintain the effectiveness of levodopa for a longer period of time. |
| Enzyme Inhibitors (MAO-B & COMT) | These medications reduce the activity of enzymes that break down dopamine in the brain, allowing dopamine to remain in the brain for longer. | These are given to help increase the effect of levodopa and make it last longer. |
| Amantadine | It helps control dyskinesia, which is an uncontrolled movement and twitching that can be caused by medications such as levodopa. | Although originally discovered as an antiviral, it is also useful for other movement disorders such as Parkinson's disease. |
| Anticholinergic medications | When dopamine decreases, the effects of another chemical called acetylcholine increase. These medications block its effects, reducing tremors and muscle stiffness. | It may be beneficial for patients with excessive tremor. |
The most important thing is that only your doctor can decide which of these medications to give and in what dosage. It depends on the patient's age, the nature of the symptoms, and many other factors.
Should we also be aware of the side effects of medications?
Like any medication, Parkinson's medications can have side effects. These vary depending on the type of medication. Don't worry, not everyone will get all of these side effects. But it's important to be aware of them.
- Levodopa: Nausea, vomiting, dizziness, headache, daytime sleepiness, and postural hypotension may occur early in the treatment. In older people, confusion, hallucinations, or psychosis may occur.
- Dopamine Agonists: These can cause nausea, drowsiness, dry mouth, confusion, and hallucinations when you first start taking them. However, these symptoms usually subside within a few days.
- Other medications: Some medications may cause side effects such as diarrhea, chest pain, insomnia, leg swelling, constipation, or dry mouth.
A very important warning: Never stop taking levodopa or reduce the dose suddenly without consulting your doctor. Doing so can lead to a very dangerous, life-threatening condition called Parkinsonism Hyperpyrexia Syndrome. It is a serious condition similar to Neuroleptic Malignant Syndrome. If you need to stop taking the medication for any reason, be sure to talk to your doctor.
Are there medications for other symptoms that are not related to movement?
Yes. Parkinson's is not just a disease that affects movement. But there are many other problems that come with it. The doctor can treat those too.
| Symptom | Potential Treatments |
|---|---|
| Constipation | Medicines that help ease stool, such as polyethylene glycol (such as MiraLax). |
| Daytime Sleepiness | Medications such as Modafinil (such as Provigil). |
| Depression or Anxiety | SSRI-type antidepressants. |
| Psychosis/Hallucinations | Specific antipsychotic medications such as pimavanserin. |
| Erectile Dysfunction | Sildenafil (like Viagra) medication. |
What else can be done besides medication?
Medication is only one part of this battle. In addition, there are many other things that can improve the patient's quality of life.
Exercise and physical therapy are very important in managing Parkinson's disease. In fact, exercise is the only thing that has been proven to slow the progression of the disease.
- Physical therapy: Physical therapy programs designed specifically for Parkinson's patients can improve balance, gait, and stability.
- Exercise: It is very important to do at least 150 minutes of cardiovascular exercise per week. Activities such as cycling and boxing have been found to be very beneficial.
- Mental Health: Living with a chronic illness like Parkinson's can be mentally challenging. So if you're feeling sad or anxious, don't hesitate to talk to a mental health professional, such as a psychologist.
When should I see the doctor again?
When taking Parkinson's medication, it's important to see your doctor regularly to check if the medication is working and if you have any new symptoms. Be sure to talk to your doctor, especially in situations like these.
- If you experience side effects that you cannot tolerate.
- If your symptoms do not improve or get worse.
- If you feel like stopping the medication.
Take-Home Message
- Although Parkinson's disease cannot be completely cured, the symptoms can be very well controlled and you can live a good life.
- Levodopa is the main and most effective medication for this disease.
- Do not stop taking medication or change the dosage for any reason without your doctor's advice.
- Exercise and physical therapy are as important as medication. Exercise can help control the progression of the disease.
- If you experience side effects or other problems, don't be afraid to talk to your doctor. He or she is always ready to help you.
