Plasma Vs Serum In Medical Diagnostics
Blood plasma and are often used in . Some tests can be done only on plasma and some only on serum. Some can be done on both, but depending on the test, use of either plasma or serum can be more practical. In addition, some tests have to be done with , such as the determination of the amount of in blood via .
Impulsive And Compulsive Behavior
Some people taking dopamine agonists may experience problems with impulsive or compulsive behaviours. For example an increased desire to gamble or engage in sexual activity. These behaviours often develop slowly so may not seem to be a problem immediately. It is important for both the person living with Parkinsons and their family to be aware of this side effect. If affected by this side effect, a reduction in dose or stopping the medication will stop the behaviour.

Other analyses showed that treatment with zonisamide, at either dose, did not significantly alter the time spent with dyskinesia compared with the placebo. However, at the higher dose, the therapy actually significantly eased dyskinesia, as measured by the Unified Parkinsons Disease Rating Scale part 4-33, when compared with the placebo.
Zonisamide 50mg significantly decreased the score on disability of dyskinesia from baseline at week 12, the researchers wrote.
Further analysis showed that the proportion of participants who experienced an improvement in off time and a significant easing of dyskinesia was significantly higher among patients given the high dose of zonisamide, compared with those given the placebo .
Collectively, these results indicate that zonisamide 50mg improves wearing off without exacerbating dyskinesia in patients with . Moreover, zonisamide 50mg may potentially improve dyskinesia, the researchers concluded.
The team noted that this analysis has several limitations: it was conducted only on trials conducted in Japan, and all analyses were post hoc meaning they were designed after the trial data had already been collected.
Further research is therefore needed to confirm the generalizability of these results, the team wrote, noting a particular need for more studies on whether zonisamide might be effective for easing dyskinesia.
Dealing With Side Effects Of Parkinsons Drugs
Its important to speak to your specialist or pharmacist if you notice anything unusual.
Changing or adding to your medication might help, and your specialist will be able to look into this.
For many people with advanced Parkinsons, medication may start to be reduced if side effects outweigh the benefits of taking medication.
But if some of the medication is reduced, you may find you get the benefits of the remaining ones, rather than the side effects.
If you experience side effects from your Parkinsons medication, you shouldnt stop taking it without guidance from your specialist.

Effects On Parkinsons Motor Symptoms
Some studies have suggested that zonisamide may help ease some motor symptoms of Parkinsons disease. The therapy was approved in Japan in 2018, under the brand name Trerief, for Parkinsons patients who saw insufficient results with standard treatment.
Now, a team led by scientists at Shandong University of Chinese Medicine, in China, conducted a review of published data, up to April 18, 2022, using the Pubmed, Cochrane Library, Web of Science, and Embase databases.
Their goal was to assess zonisamides effects in people with Parkinsons disease or the related condition dementia with Lewy bodies .
The meta-analysis included results from seven appropriately-controlled clinical trials that compared zonisamide against a placebo. Four of the studies were conducted in Parkinsons patients, and the other three in those with DLB.
All of the trials were conducted in Japan between 2007 and 2021. Collectively, they included 916 people with Parkinsons and 833 with DLB. The first study tested three doses of zonisamide , after which the remaining six trials only included the two lower doses.
The studies ranged in length from 3.5 months to about a year, and in all of them, participants could continue their standard approved Parkinsons treatments.
Pooled data on the Unified Parkinsons Disease Rating Scale Part III, which assesses the severity of motor symptoms, showed that zonisamide treatment significantly reduced scores by an average of 2.27 points relative to a placebo.
The Origin Of Plasmapheresis
Dr. José Antonio Grifols Lucas, a scientist from Vilanova i la Geltrú, Spain, founded Laboratorios Grifols in 1940. Dr. Grifols pioneered a first-of-its-kind technique called plasmapheresis, where a donor’s red blood cells would be returned to the donor’s body almost immediately after the separation of the blood plasma. This technique is still in practice today, almost 80 years later. In 1945, Dr. Grifols opened the world’s first plasma donation center. Thirteen years after the center’s opening, Dr. Grifols unexpectedly died at the young age of 41 due to leukemia.

Among the outcomes were the UP-DRS II total score, the UPDRS III total score, and the daily off time. UPDRS Part IV, No. 32 includes the following: worsened, improved, no new onset, unchanged with scores 1, and new onset. UPDRS Part IV, No. 33 includes the following: worsened, improved, no new onset, and unchangedwithscores 1. UP-DRS Part IV, No. 34 includes the following: worsened, improved, no new onset, and unchangedwithscores 1. In addition, 39 adverse events were included as indicators of treatment safety outcomes. We calculated the means and standard deviations for continuous dating . The data were transformed using existing formulae in the absence of a mean and standard deviation. A third reviewer resolved disagreements independently.
Impulsive And Compulsive Behaviours
People who experience impulsive and compulsive behaviours cant resist the temptation to carry out an activity often one that gives immediate reward or pleasure.
Behaviours may involve gambling, becoming a shopaholic, binge eating or focusing on sexual feelings and thoughts. This can have a huge impact on peoples lives including family and friends.
Not everyone who takes Parkinsons medication will experience impulsive and compulsive behaviours, so these side effects should not put you off taking your medication to control your symptoms.
If you have a history of behaving impulsively you should mention this to your GP, specialist or Parkinsons nurse.
Asking your specialist to make changes to your medication regime or adjusting the doses that you take is the easiest way to control impulsive and compulsive behaviours. So, if you or the person you care for is experiencing this side effect, tell your healthcare professional as soon as possible before it creates large problems.
If you are not able to get through to your healthcare professional straight away, you can call our Parkinsons UK helpline on 0808 800 0303.
We have advice that can help you manage impulsive and compulsive behaviours as well as information on what behaviour to look out for.

Ask Your Doctor If You Can Change The Time At Which You Take Your Meds
Dont experiment with the timing of your Parkinsons disease drugs yourself, because this can result in a variety of complications. You can, on the other hand, ask your doctor whether it is possible to take your medications at a different time of day. Meds that induce sleepiness may be better taken before bedtime, for instance, while those drugs that have insomnia as a side effect may be better taken earlier in the day. Your doctor will have had more experience in prescribing the medications you take, and will have helpful tips to share.
How Dopamine Agonists Are Used
Dopamine agonists are used at all stages of Parkinsons. You might take them alone when treatment is being started, or alongside levodopa to provide a more effective treatment with fewer side effects.
Treatment with dopamine agonists has to be started carefully to minimise the risk of side effects, with the dose gradually increasing until you and your specialist or Parkinsons nurse are happy that your symptoms are under control. Some dopamine agonists are available as one a day tablets. These can be a better option for the body and may help both movement and other symptoms of Parkinsons.

Modulation Of Receptor Expression
Recently, Oki et al. reported that ZNS could ameliorate LID by modulating the expression of receptors. They designed different models of levodopa-ZNS administration in four groups, namely, intermittent ZNS and levodopa injection, intermittent levodopa injection, continuous levodopa infusion, and no medication. Two weeks after the treatment, they analyzed the mRNA expression of endocannabinoid CB1 receptor, D1 and D2 receptors, and adenosine A2A receptor in the striatum of PD model rats in each group. Their results indicated that intermittent prescription of levodopa induced LID, which was related to the upregulation of dopamine D1 and adenosine A2A receptors. ZNS injection improved LID by downregulation of adenosine A2A and endocannabinoid CB1 receptors.
Side Effects Of Medication
All prescribed medication can have potential side effects, including those used to treat Parkinsons.
Many people find their Parkinsons medication works very well when they start taking it, but this may change over time and side effects can develop.
Some things you think are symptoms of Parkinsons may actually be side effects of medication.
Some peoples side effects will have a big impact on their lives and have to be kept under control along with the symptoms.

When selegiline is taken together with levodopa, side effects such as dyskinesias , hallunications or vivid dreaming may sometimes occur or worsen.
When people have taken rasagiline on its own , the most commonly reported side effects have been:
When taken with levodopa, the most common reports have been of uncontrolled movements and accidental falls.
Many of these side effects may be due to the increase in dopamine caused by rasagiline or selegiline. Your doctor or consultant can alter the dosage to correct these effects.
If youre taking some types of antidepressant, you might not be able to take MAO-B inhibitors, as these drugs can interact with each other to raise blood pressure to a dangerous level.
Your neurologist or pharmacist is the best person to advise on potential interactions with other medications.
Zonisamide With Levodopa May Reduce Risk Of Dementia Other Parkinsons
The standard treatment for Parkinsons is levodopa and its derivatives, used to replace the dopamine loss seen in patients with the disease. While these medications are generally effective at controlling symptoms, over time they almost always lead to dyskinesia as a side effect. It also is common for people treated with these medicines to experience off time, when their symptoms are not being fully controlled by the therapy.
Zonisamide was originally developed to treat epilepsy, but research has shown it also may be beneficial for people with Parkinsons. In Japan, the therapy is approved to treat Parkinsons and is marketed as Trerief.
Now, researchers at Fukuoka University and from Sumitomo Dainippon Pharma the company that developed zonisamide conducted an analysis of clinical trial data to understand the medications effect on off time and dyskinesia.
The team analyzed data for 212 patients who participated in one of two Japanese clinical trials, in which participants were given either a placebo or zonisamide at doses of 25 or 50 mg per day for 12 weeks, or about three months. The mean patient age was 63.7 and the mean disease duration was just over 11 years. About a third of participants were male. All were being treated with levodopa.
The lower dosage of zonisamide was associated with a slight reduction in off time, but the difference from placebo was not statistically significant.

Inhibition Of Monoamine Oxidase
ZNS is capable of inhibiting monoamine oxidase-B . Sonsalla et al. reported that ZNS regulates MAO-B activity, reversibly, with an IC50 of 25 M in vitro.
Previous studies have demonstrated that the metabolism of dopamine by MAO-B produces reactive oxygen species , which contribute to nigrostriatal degeneration . ZNS prevents the formation of 1-methyl-4-phenylpyridinium , which is derived from 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine via MAO-B, and thereby inhibits the oxidation of dopamine to hydrogen peroxide and the related neurotoxic effects .

Epilepsy Drug May Treat Parkinson’s
The epilepsy drug zonisamide may help curb the tremors and other movement problems of Parkinson’s, a Japanese study shows.
Jan. 4, 2007 — The epilepsy drug zonisamide may help curb the tremors and other movement problems of Parkinson’s, a Japanese study shows.
Zonisamide is sold in the U.S. generically and under the brand name Zonegran.
In Parkinson’s disease, the brain cells that make dopamine, a chemical that helps control the body’s movements, gradually falter and die. Symptoms include tremor, movement problems, and unsteady balance.
The disease usually starts between the ages of 50 and 65. There is no cure, but medications can help manage Parkinson’s symptoms.
The new study on zonisamide for Parkinson’s comes from researcher Miho Murata, MD, PhD, of Japan’s National Center of Neurology and Psychiatry, and colleagues. It appears in the Jan. 2 issue of Neurology.
