What Are The Effects Of Parkinson’s Disease

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
• Light-headedness.

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.

Research Is Underway To Further Understand The Cardiac Effects Of Parkinsons

It is possible to image the sympathetic nervous system of the human heart by injecting a radioactive tracer, meta-iodo-benzyl-guanidine, . Development of this technique, known as MIBG cardiac imaging, holds much promise as a test to confirm the diagnosis of PD , to identify those who are at risk of developing PD in the future, and to distinguish PD from related disorders. MIBG cardiac imaging is still considered an experimental procedure for detection of PD and is not yet in use as a clinical tool for this purpose.

A recent research study was conducted in monkeys in which the destruction of the sympathetic nerves of the heart was chemically induced to mimic the changes that are seen in PD. The cardiac system was then imaged using a number of new-generation radioactive tracers, which bind to markers of inflammation and oxidative stress. This model system may help to shed light on the molecular changes that accompany the loss of the sympathetic nerves of the heart and can also be used to track the response of the cardiac system to therapeutic agents.

Ways To Cope With The Side Effects Of Parkinsons Disease Drugs

Prescription drugs are the most powerful tools modern science has available to help you fight your Parkinson’s disease symptoms but the very medications designed to make your life better can also cause side effects.

These side effects range from unpleasant to downright scary .

If you have Parkinson’s disease, you will already be familiar with the most frequently prescribed Parkinson’s disease medications:

• Levodopa works to boost your dopamine levels indirectly, and is almost always prescribed in combination with carbidopa. Brand names include Sinemet, Rytary, Parcopa, and Stalevo, and they’re powerful weapons in the fight against the motor symptoms of Parkinson’s disease.
• Dopamine agonists like pramipexole , ropinirole , apomorphine , and Neupro act similarly to dopamine, thereby reducing your Parkinson’s disease symptoms.
• COMT inhibitors, like entacapone , are prescribed to make levodopa work more effectively.
• MAO-B inhibitors help your brain use the dopamine it does have access to more efficiently, and examples are selegiline and rasagiline .
• Amantadine is both an anti-flu and Parkinson’s drug, and it is particularly useful in combating the involuntary movements levodopa can result in.

• Dyskinesia involuntary movements, which can strike the arms, legs, torso, and face
• Nausea and vomiting
• Diarrhea, constipation, and urinary difficulties, including discolored urine and finding it hard to pee
• Dizziness or lightheadedness

Drugs To Treat Parkinsons Disease

Study conducted by medical researchers have compared two drugs named Levodopa and Pramipexole, which is employed generally as the first treatment line associated with the parkinsons disease problem. These drugs use various mechanisms to counteract with declining in the dopamine production in human brain, which is a result of progressive cell loss to secrete neuro chemicals in human brain. Levodopa is a type of amino acid, which human body metabolizes to form dopamine. On the other side, Pramipexole is a type of dopamine agonist, which binds with dopamine receptors present on cells in human brain and mimics the molecular function associated with the chemical.

Motor Circuit In Parkinson Disease

The basal ganglia motor circuit modulates the cortical output necessary for normal movement .

Signals from the cerebral cortex are processed through the basal ganglia-thalamocortical motor circuit and return to the same area via a feedback pathway. Output from the motor circuit is directed through the internal segment of the globus pallidus and the substantia nigra pars reticulata . This inhibitory output is directed to the thalamocortical pathway and suppresses movement.

Two pathways exist within the basal ganglia circuit, the direct and indirect pathways, as follows:

• In the direct pathway, outflow from the striatum directly inhibits the GPi and SNr striatal neurons containing D1 receptors constitute the direct pathway and project to the GPi/SNr

• The indirect pathway contains inhibitory connections between the striatum and the external segment of the globus pallidus and between the GPe and the subthalamic nucleus striatal neurons with D2 receptors are part of the indirect pathway and project to the GPe

The STN exerts an excitatory influence on the GPi and SNr. The GPi/SNr sends inhibitory output to the ventral lateral nucleus of the thalamus. Dopamine is released from nigrostriatal neurons to activate the direct pathway and inhibit the indirect pathway. In Parkinson disease, decreased striatal dopamine causes increased inhibitory output from the GPi/SNr via both the direct and indirect pathways .

What Treatments Are Available

Many Parkinson’s patients enjoy an active lifestyle and a normal life expectancy. Maintaining a healthy lifestyle by eating a balanced diet and staying physically active contributes to overall health and well-being. Parkinson’s disease can be managed with self-care, medication, and surgery.

Self careExercise is as important as medication in the treatment of PD. It helps maintain flexibility and improves balance and range of motion. Patients may want to join a support group and continue enjoyable activities to improve their quality of life. Equally important is the health and well being of the family and caregivers who are also coping with PD. For additional pointers, see Coping With Parkinsons Disease.

These are some practical tips patients can use:

Medications There are several types of medications used to manage Parkinson’s. These medications may be used alone or in combination with each other, depending if your symptoms are mild or advanced.

After a time on medication, patients may notice that each dose wears off before the next dose can be taken or erratic fluctuations in dose effect . Anti-Parkinsons drugs can cause dyskinesia, which are involuntary jerking or swaying movements that typically occur at peak dosage and are caused by an overload of dopamine medication. Sometimes dyskinesia can be more troublesome than the Parkinsons symptoms.

Determination Of Dopamine And Glutamate Concentrations

Dissection procedure

Coronal slices were obtained manually from brains at the level containing the caudate-putamen, globus pallidus and substantia nigra. Subsequently, these structures were dissected and homogenized in 2040 vol of cold 150 mM potassium phosphate buffer, pH 6.8 and the dopamine and glutamate content of each homogenate was analysed. An aliquot of each homogenate was used to determine the protein concentration .

Determination of dopamine content

Dopamine content was determined using HPLC with electrochemical detection . Briefly, homogenates were diluted in ice-cold 0.2 N perchloric acid containing 0.2 mM sodium disulphite and 0.45 mM EDTA, and dihydroxybenzylamine was added as an internal standard. The diluted homogenates were then centrifuged, and the supernatants were injected into the HPLC system. This system consisted of a Spectra-Physics 8810 pump and an RP-18 column . The mobile phase, previously filtered and degassed, was a solution of 100 mM citric acid, 100 mM sodium acetate, 1.2 mM heptane sulphonate, 1 mM EDTA and 7% methanol , and the flow rate was 0.8 mL·min1. The effluent was monitored with a coulochemical detector using a procedure of oxidation/reduction . The signal was recorded on a Spectra-Physics 4290 integrator from the analytical cell #2, with a sensitivity of 50 nA . Dopamine levels were calculated from areas under the peaks using the comparison with the internal standard area. Values are expressed as ng·mg1 of protein.

Parkinson’s Disease Brain Vs Normal Brain: What’s Different

It’s not yet possible to spot the difference between a brain with Parkinson’s and a normal, “healthy” brain on an MRI scan. However, since Lewy bodies were first found in the substantia nigra in 1927, doctors have known they are a feature of Parkinson’s disease. The presence of these Lewy bodies is thought to be what separates people with Parkinson’s disease from the general population. However, Lewy bodies can only be diagnosed with certainty during a brain autopsy after death.

Is Parkinson’s Diagnosed In The Brain

Parkinson’s disease is one of the most challenging neurological disorders to diagnose and treat. If your doctor suspects you have Parkinson’s disease, you will usually be referred to a neurologist for further tests. These tests will involve certain movements and exercises to check your symptoms.

A neurologist will look for motor symptoms such as:

• A tremor that occurs at rest
• Slowed movement
• Muscle stiffness

If you have two or more of these symptoms and your doctor has taken blood tests to rule out other causes, it’s likely you will be diagnosed with Parkinson’s disease. Your symptoms will be closely monitored to see any progression of Parkinson’s disease, which can take years.

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.

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.

Deep Brain Stimulation For Parkinson’s: Am I A Candidate

Deep brain stimulation is not a cure, but it can relieve your symptoms from Parkinson’s disease when medications are not an option. Only you and your doctor can decide if this surgical procedure is right for you. You may be a candidate for deep brain stimulation if:

• You have idiopathic Parkinson’s disease. Patients with atypical parkinsonism are not candidates.
• You have good motor function and independence during your best “on” state when taking the drug Sinemet.

How Is Parkinson’s Disease Diagnosed

Diagnosis is difficult at every stage of the disease, but particularly in the early stages. No single test can provide a diagnosis. A diagnosis will likely involve physical and neurological examinations, conducted over time to assess changes in reflexes, coordination, muscle strength, and mental function. Your doctor might also see how you respond to medicine.

You may need to have brain imaging tests to rule out other conditions that might be causing your symptoms. Such tests could include MRI and CT scans and possibly some other types of scans. Blood tests may also be done to exclude other illnesses.

The Nervous System & Dopamine

To understand Parkinson’s, it is helpful to understand how neurons work and how PD affects the brain .

Nerve cells, or neurons, are responsible for sending and receiving nerve impulses or messages between the body and the brain. Try to picture electrical wiring in your home. An electrical circuit is made up of numerous wires connected in such a way that when a light switch is turned on, a light bulb will beam. Similarly, a neuron that is excited will transmit its energy to neurons that are next to it.

Neurons have a cell body with branching arms, called dendrites, which act like antennae and pick up messages. Axons carry messages away from the cell body. Impulses travel from neuron to neuron, from the axon of one cell to the dendrites of another, by crossing over a tiny gap between the two nerve cells called a synapse. Chemical messengers called neurotransmitters allow the electrical impulse to cross the gap.

Neurons talk to each other in the following manner :

Slice Title3 Things We Know About Parkinson’s

Parkinson’s develops when cells in the brain stop working properly and are lost over time. These brain cells produce a chemical called dopamine.

Symptoms start to appear when the brain cant make enough dopamine to control movement properly.

There are 3 main symptoms – tremor , slowness of movement and rigidity – but there are many other symptoms too.

Take Your Parkinson’s Medications As Prescribed

Take your medications exactly as prescribed by your doctor in the right dose, and at the right time of day, and in the right way. You’ll be given instructions when you’re first prescribed a drug. Some medications are meant to be taken on an empty stomach, while others should be taken with food.

Parkinson’s patients who have trouble remembering when and in what dose to take their drugs can:

• Set a medication alarm on a smart phone, for instance. There are even special apps to remind you when to take your meds.
• Have their pills organized into a special medication box so they don’t have to think about what to take each time.
• Many pharmacies are able to put together “compliance medicine packages” that organize your drugs in a way that makes it easier to take them at the right time.
• When you take your meds, mark it off on a calendar.
• If necessary, a partner or carer can help you remember to take your drugs.
