Maintaining Your Normal Pd Medication Schedule
Maintaining your PD medication schedule is crucial for anyone with PD. The correct timing and dosage are essential to your comfort and well-being. However, oftentimes when undergoing surgery, there may be restrictions regarding when you can and cannot take medications. Here are a few tips to navigate this issue:
How Parkinsons Disease Affects The Autonomic Nervous System And The Heart
In PD, there are two major reasons why the automatic control of the cardiac system is impaired. First, areas of the brain that control this system often contain Lewy bodies and have undergone neurodegeneration. In addition, the autonomic nervous system itself is directly affected by Lewy body-like accumulations and neurodegeneration. This means, when the baroreceptors in the heart and carotid artery sense a drop in blood pressure and try to generate a signal to the heart and blood vessels to increase the blood pressure, the message may not get through. This results in neurogenic orthostatic hypotension , or drops in blood pressure upon standing due to autonomic nervous system dysfunction. There are no medications that can cure nOH by restoring the autonomic nervous system in PD. nOH however, can be treated. Read more about nOH and its treatments here.
Structural problems of the heart such as coronary artery disease or cardiomyopathy are not thought to be part of the pathology of PD, although of course, could co-exist with PD.
Diagnosis And Management Of Parkinsons Disease
There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.
No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.
People can manage their Parkinsons disease symptoms through:
- seeing a Doctor who specialises in Parkinsons
- medication
- multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
- deep brain stimulation surgery .

Living With Parkinson’s Disease
As Parkinson’s develops, a person who has it may slow down and won’t be able to move or talk quickly. Sometimes, speech therapy and occupational therapy are needed. This may sound silly, but someone who has Parkinson’s disease may need to learn how to fall down safely.
If getting dressed is hard for a person with Parkinson’s, clothing with Velcro and elastic can be easier to use than buttons and zippers. The person also might need to have railings installed around the house to prevent falls.
If you know someone who has Parkinson’s disease, you can help by being a good friend.
Drugs And Medication Used To Treat Parkinsons Disease
A number of different drugs can be used to treat Parkinsons.
Levodopa
Levodopa is the most common treatment for Parkinsons. It helps to replenish dopamine.
About 75 percent of cases respond to levodopa, but not all symptoms are improved. Levodopa is generally given with carbidopa.
Carbidopa delays the breakdown of levodopa which in turn increases the availability of levodopa at the blood-brain barrier.
Dopamine agonists
Dopamine agonists can imitate the action of dopamine in the brain. Theyre less effective than levodopa, but they can be useful as bridge medications when levodopa is less effective.
Drugs in this class include bromocriptine, pramipexole, and ropinirole.
Anticholinergics
Anticholinergics are used to block the parasympathetic nervous system. They can help with rigidity.
Benztropine and trihexyphenidyl are anticholinergics used to treat Parkinsons.
Amantadine
Amantadine can be used along with carbidopa-levodopa. Its a glutamate-blocking drug . It offers short-term relief for the involuntary movements that can be a side effect of levodopa.
COMT inhibitors
Catechol O-methyltransferase inhibitors prolong the effect of levodopa. Entacapone and tolcapone are examples of COMT inhibitors.
Tolcapone can cause liver damage. Its usually saved for people who do not respond to other therapies.
Ectacapone does not cause liver damage.
Stalevo is a drug that combines ectacapone and carbidopa-levodopa in one pill.
MAO-B inhibitors

What Are The Treatments
Currently there is no cure for Parkinsons disease.
Symptoms can be mild in the early stages of the condition and people might not need immediate treatment. Your doctor and specialist will monitor your situation.
There are several different types of drugs used to treat Parkinsons disease. Drug treatments are tailored to each individuals needs and are likely to involve a combination of different drugs. Your medication should be reviewed regularly. It is likely that, over time, changes will be made to the types of drugs you take and the doses you take each day.
The main types of drug treatment for Parkinsons disease are:
- drugs which replace dopamine
- drugs which mimic the role of dopamine
- drugs which inhibit the activity of acetylcholine
- drugs which prevent the body breaking down dopamine
- other drugs such as anti-sickness medication
Everybody is affected differently by medication. The possible side effects of Parkinsons disease drugs include nausea , vomiting , tiredness and dizziness. Some people might experience confusion, nightmares and hallucinations. For some people, dopamine agonists have been linked to compulsive behaviour such as addictive gambling or hypersexuality .
The effectiveness of the main drug treatment levodopa can wear off over time and its long-term use can cause some people to develop involuntary twisting or writhing movements of the arms, legs or face . To reduce the risk, doctors might delay the use of levodopa for younger people.

Parkinsons & The Substantia Nigra
The substantia nigra is a part of the midbrain just above the spinal cord. Itâs also part of the basal ganglia, an area of the brain that scientists believe controls movement. Healthy brains contain an abundance of dopamine-producing cells in this part of the brain. The natural chemical dopamine is essential for regulating both movement and mood.
A dramatic 80% drop in these dopamine cells is what causes the symptoms of Parkinsonâs disease. Doctors and researchers are unsure why this process occurs. In addition to the effects previously mentioned, this dopamine loss may cause patients to experience slowness of movement, an inability to concentrate, and speech difficulties.
How Is Parkinsons Diagnosed
Doctors use your medical history and physical examination to diagnose Parkinson’s disease . No blood test, brain scan or other test can be used to make a definitive diagnosis of PD.
Researchers believe that in most people, Parkinson’s is caused by a combination of environmental and genetic factors. Certain environmental exposures, such as pesticides and head injury, are associated with an increased risk of PD. Still, most people have no clear exposure that doctors can point to as a straightforward cause. The same goes for genetics. Certain genetic mutations are linked to an increased risk of PD. But in the vast majority of people, Parkinsons is not directly related to a single genetic mutation. Learning more about the genetics of Parkinsons is one of our best chances to understand more about the disease and discover how to slow or stop its progression.
Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.
Men are diagnosed with Parkinsons at a higher rate than women and whites more than other races. Researchers are studying these disparities to understand more about the disease and health care access and to improve inclusivity across care and research.
Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.
The Michael J. Fox Foundation has made finding a test for Parkinsons disease one of our top priorities.

Advancement In Parkinsons Disease
With the progress of Parkinsons disease with time, symptoms associated with the problem become worse typically and many new problems emerge. Despite patients receive benefits with the intake of anti-Parkinson medication the benefit fails to last for a long time even when they intake it frequently.
Most of the patients usually experience involuntary movements to make them, as looking fidgety when they intake the medicine and otherwise works the best. Hence, it is very much essential to emphasize such movements typically and do not bother about the condition of patients too much.
Other problems, which may take place with the progress of Parkinsons disease, are-
- Problems associated with balance and gait, along with falls
- Difficulty in communication or impairment of speech
- Difficulty in swallowing
- Cognitive impairment, such as memory and thinking
- Behavioral problems
- .
Some of the problems are of very much difficult to treat with medicines. However, any experienced doctor or a neurologist specializes in movement disorder will still may provide the necessary support and guidance for patients even during the advanced phases of the Parkinsons disease.
Medicines For Parkinsons Disease
Medicines prescribed for Parkinsons include:
- Drugs that increase the level of dopamine in the brain
- Drugs that affect other brain chemicals in the body
- Drugs that help control nonmotor symptoms
The main therapy for Parkinsons is levodopa, also called L-dopa. Nerve cells use levodopa to make dopamine to replenish the brains dwindling supply. Usually, people take levodopa along with another medication called carbidopa. Carbidopa prevents or reduces some of the side effects of levodopa therapysuch as nausea, vomiting, low blood pressure, and restlessnessand reduces the amount of levodopa needed to improve symptoms.
People with Parkinsons should never stop taking levodopa without telling their doctor. Suddenly stopping the drug may have serious side effects, such as being unable to move or having difficulty breathing.
Other medicines used to treat Parkinsons symptoms include:
- Dopamine agonists to mimic the role of dopamine in the brain
- MAO-B inhibitors to slow down an enzyme that breaks down dopamine in the brain
- COMT inhibitors to help break down dopamine
- Amantadine, an old antiviral drug, to reduce involuntary movements
- Anticholinergic drugs to reduce tremors and muscle rigidity

How Will The Disease Affect My Life
Most people who have Parkinsonâs live a normal to a nearly normal lifespan, but the disease can be life changing.
For some people, treatment keeps the symptoms at bay, and they’re mostly mild. For others, the disease is much more serious and really limits what you’re able to do.
As it gets worse, it makes it harder and harder to do daily activities like getting out of bed, driving, or going to work. Even writing can seem like a tough task. And in later stages, it can cause dementia.
Even though Parkinson’s can have a big impact on your life, with the right treatment and help from your health care team, you can still enjoy the things you love. It’s important to reach out to family and friends for support. Learning to live with Parkinson’s means making sure you get the backing you need.
What Are The Complications Of Parkinson Disease
Parkinson disease causes physical symptoms at first. Problems with cognitive function, including forgetfulness and trouble with concentration, may arise later. As the disease gets worse with time, many people develop dementia. This can cause profound memory loss and makes it hard to maintain relationships.
Parkinson disease dementia can cause problems with:
- Speaking and communicating with others
- Problem solving
- Forgetfulness
- Paying attention
If you have Parkinson disease and dementia, in time, you likely won’t be able to live by yourself. Dementia affects your ability to care of yourself, even if you can still physically do daily tasks.
Experts don’t understand how or why dementia often occurs with Parkinson disease. Its clear, though, that dementia and problems with cognitive function are linked to changes in the brain that cause problems with movement. As with Parkinson disease, dementia occurs when nerve cells degenerate, leading to chemical changes in the brain. Parkinson disease dementia may be treated with medicines also used to treat Alzheimer’s disease, another type of dementia.

What Can Be Done About These Unpleasant Gi Problems
Unfortunately, research studies on GI problems related to PD have been few and far between, so doctors do not have any tried and true methods to deal with them. Some of the drugs to treat GI problems in people without PD cannot be used for those with PD because these drugs negatively impact dopamine systems in the brain.
If you have PD and experience constipation, it makes sense to try to use safe and simple methods to address this issue before you add new drugs to your daily regimen. Increasing dietary fiber and drinking lots of water and other fluids is a reasonable first step in treatment. If your doctor approves it, you might also consider taking fiber supplements, such as psyllium or methylcellulose. If these simple methods dont work, your doctor might consider giving you a stool softener or a laxative.
Medications For People With Parkinsons Disease
Symptoms of Parkinsons disease result from the progressive degeneration of nerve cells in the brain and other organs such as the gut, which produce a neurotransmitter called dopamine. This causes a deficiency in the availability of dopamine, which is necessary for smooth and controlled movements. Medication therapy focuses on maximising the availability of dopamine in the brain. Medication regimes are individually tailored to your specific need. Parkinsons medications fit into one of the following broad categories:
- levodopa dopamine replacement therapy
- dopamine agonists mimic the action of dopamine
- COMT inhibitors used along with levodopa. This medication blocks an enzyme known as COMT to prevent levodopa breaking down in the intestine, allowing more of it to reach the brain
- anticholinergics block the effect of another brain chemical to rebalance its levels with dopamine
- amantadine has anticholinergic properties and improves dopamine transmission
- MAO type B inhibitors prevent the metabolism of dopamine within the brain.

Cognitive Changes In Pd
Cognitive symptoms in Parkinsons disease are common, though not every person experiences them. In some people with PD, the cognitive changes are mild. In others, however, cognitive deficits may become more severe and impact daily functioning. Similar to slowness of movement , people with Parkinsons disease often report slower thinking and information processing . Attention and working memory, executive function, and visuospatial function are the most frequently affected cognitive domains in PD.
Cognitive deficits that are mild and do not impair ones ability to carry out activities of daily living have been termed mild cognitive impairment. Studies estimate that mild cognitive impairment occurs in about 20-50% of patients with PD. We now recognize that mild cognitive changes may be present at the time of Parkinsons disease diagnosis or even early in the course of PD. They may or may not be noticeable to the person. They may or may not affect work or activities, depending on the demands of specific tasks and work situations.
Location of the substantia nigra. FrozenManCC BY-SA 4.0
The substantia nigra is an area of the mid brain located at the top of the spinal cord, which has been the focus of much work into how Parkinsons affects the brain.
You can read more about the alpha-synuclein protein, and how it plays a role in the spread of Parkinsons, in a previous blog post:
Signs Of Parkinsons Disease
In 1817, Dr. James Parkinson published An Essay on the Shaking Palsy describing non-motor, as well as, motor symptoms of the illness that bears his name. Parkinsons is not just a movement disorder, explained Dr. Shprecher. Constipation, impaired sense of smell, and dream enactment can occur years before motor symptoms of Parkinsons. The latter, caused by a condition called REM sleep behavior disorder, is a very strong risk factor for both Parkinsons and dementia . This has prompted us to join a consortium of centers studying REM sleep behavior disorder.

Living With Parkinson Disease
These measures can help you live well with Parkinson disease:
- An exercise routine can help keep muscles flexible and mobile. Exercise also releases natural brain chemicals that can improve emotional well-being.
- High protein meals can benefit your brain chemistry
- Physical, occupational, and speech therapy can help your ability to care for yourself and communicate with others
- If you or your family has questions about Parkinson disease, want information about treatment, or need to find support, you can contact the American Parkinson Disease Association.
Treatment Challenges In Women
Women with PD may encounter more problems during treatment than men, and often take longer to seek treatment. A 2011 study found that the time between symptom onset and seeing a movement disorder specialist was 61 percent longer for women.
Women are also exposed to higher doses of PD medications such as levodopa. A 2014 studyTrusted Source examined the levels of levodopa in the blood of 128 people with PD over 3 hours. It found that levodopa concentrations were significantly higher in women than in men during this time.
Higher exposure to levodopa can lead to an increased rate of negative side effects such as dyskinesia .
Women also receive DBS or surgery less often than men do. A small 2003 studyTrusted Source found that at the time of surgery, women had a longer duration of disease than men . They also had more severe symptoms. However, after surgery they experienced more improved quality of life.
A 2014 study found that although DBS was equally effective for men and women, women were less likely to be treated due to more severe dyskinesia. Additionally, a
Why are there differences in PD between men and women? It seems likely that the hormone estrogen has a protective effect for women.
A 2020 cohort study found that a later age of menopause and longer duration of fertility were associated with a lower risk of PD. These are both markers of estrogen exposure over the course of a womans lifetime.
