Body System #12: Digestive System
The digestive system breaks down food, extracts nutrients into the bloodstream, and excretes waste. This body system is made up of the digestive tract, liver, pancreas, and gallbladder.
Diseases and Disorders of the Digestive System
- Irritable Bowel Syndrome IBS is an intestinal disorder causing pain in the stomach, gas, diarrhea, and constipation.
- Diverticulitis Diverticulitis is an inflammation of one or more small pouches in the digestive tract.
- Gastroesophageal Reflux Disease GERD is a condition in which stomach acid irritates the esophagus.
- Crohns Disease This is a chronic inflammatory bowel disease that affects the lining of the digestive tract.

Average Age Of Parkinson’s Diagnosis
Parkinson’s disease is a brain condition that causes shaking, problems with balance and coordination, and stiffness in your arms and legs. There’s no cure for it, but there are treatments;that can help with your symptoms, so an early diagnosis is important.
Doctors believe that most people start to show signs of Parkinson’s disease sometime in middle age. The average age for someone to be diagnosed with Parkinson’s is around 60 years old.
Your odds of developing the condition rise with your age, but only to a certain point it’s more common in people between ages 70 and 80 than it is in people who are between ages 60 and 70. But if you haven’t been diagnosed with Parkinson’s by the time you’re 80 years old, your odds of getting it are small in fact, they’re substantially smaller than they were when you were 60 or 70.
Take Care Of Yourself
Probably one of the most important, and sometimes difficult, things caregivers can do is to take care of themselves. This includes maintaining mental and physical health by making and keeping your own medical and dental appointments. As a caregiver, it is important to keep your job whenever possible as it provides not only financial help and possibly insurance coverage, but also a sense of self-esteem. Join a support group;for caregivers;if possible. Support groups help you meet people who are going through what you are going though, vent frustrations, give and receive mutual support, and exchange resource information and coping strategies. Whenever possible get your sleep, take breaks, make and keep social activities, and try to keep your sense of humor.

Living With Parkinsons Disease
Depending on severity, life can look very different for a person coping with Parkinsons Disease. As a loved one, your top priority will be their comfort, peace of mind and safety. Dr. Shprecher offered some advice, regardless of the diseases progression. Besides movement issues Parkinsons Disease can cause a wide variety of symptoms including drooling, constipation, low blood pressure when standing up, voice problems, depression, anxiety, sleep problems, hallucinations and dementia.; Therefore, regular visits with a neurologist;experienced with Parkinsons are important to make sure the diagnosis is on target, and the symptoms are monitored and addressed.; Because changes in your other medications can affect your Parkinsons symptoms, you should remind each member of your healthcare team to send a copy of your clinic note after every appointment.
Dr. Shprecher also added that maintaining a healthy diet and getting regular exercise can help improve quality of life.;Physical and speech therapists;are welcome additions to any caregiving team.
What Medications Are Used To Treat Parkinsons Disease
Medications are the main treatment method for patients with Parkinsons disease. Your doctor will work closely with you to develop a treatment plan best suited for you based on the severity of your disease at the time of diagnosis, side effects of the drug class and success or failure of symptom control of the medications you try.
Medications combat Parkinsons disease by:
- Helping nerve cells in the brain make dopamine.
- Mimicking the effects of dopamine in the brain.
- Blocking an enzyme that breaks down dopamine in the brain.
- Reducing some specific symptoms of Parkinsons disease.
Levodopa: Levodopa is a main treatment for the slowness of movement, tremor, and stiffness symptoms of Parkinsons disease. Nerve cells use levodopa to make dopamine, which replenishes the low amount found in the brain of persons with Parkinsons disease. Levodopa is usually taken with carbidopa to allow more levodopa to reach the brain and to prevent or reduce the nausea and vomiting, low blood pressure and other side effects of levodopa. Sinemet® is available in an immediate release formula and a long-acting, controlled release formula. Rytary® is a newer version of levodopa/carbidopa that is a longer-acting capsule. The newest addition is Inbrija®, which is inhaled levodopa. It is used by people already taking regular carbidopa/levodopa for when they have off episodes .

Why Is Distinguishing Young
Socially, people who are affected by PD at a younger age experience the disease differently they may be at a different stage of their career and often have less time to engage in their own care. They may also have children or are planning to have children and have questions regarding passing on PD genes.
Medically, doctors tailor treatment when it is a younger person with PD. The younger you are, the more likely the disease is genetic. Your care team may offer genetic testing or counseling. Younger brains also have a higher neuroplasticity potential which allows the brain to handle and respond to disease and therapy differently.;
What Is The Average Age To Get Parkinsons Disease
Parkinsons disease indicates a neurodegenerative disorder affecting predominately various dopamine-producing neurons in particular brain areas known commonly as substantia nigra.
Symptoms in this case develop generally slow for many years. In addition, progression of various symptoms is slightly different among different persons because of the diversity prevails in the disease. People suffering from Parkinsons disease problem usually deal with-
Tremor usually while taking rest and pill rolling type of tremor in the hands. However, the patients may even deal with other tremor forms, which are-
- Slow body movements.
- Rigidity in limbs.
- Problems in balance of body and gait.
Main reason behind the Parkinsons disease problem is entirely unknown. Despite no cure is available until now, treatment options in case of Parkinsons disease may vary largely, which may include surgical procedures and medications. The problem itself is not a dreadful one; its complications may sometimes become serious.

Treatment For The Motor Symptoms Of Parkinsons Disease
There are many ways to deal with Parkinsons disease motor symptoms, including medications, occupational therapy and lifestyle adjustments. You may find that tremors make you more susceptible to accidents such as tripping, falling or spilling hot liquids so you must take care and ask for the help and support you need.
Unlike other Parkinsons motor symptoms, tremors can be hard to treat with medication. However, medicines can be helpful for treating symptoms such as Parkinsons disease gait impairments, which can have a major impact on your life. The gait of Parkinsons disease presents slightly differently in each patient. Some experience the Parkinsons disease shuffling gate, which can make movement markedly slower and make it look like you are dragging your feet. You may also experience reduced arm movement while walking.
In Parkinsons disease, freezing of gait is characterized by hesitation before stepping forward, or a feeling like your feet have frozen to the floor. Frozen gait usually only lasts for a step or two, but you will need to be careful when crossing busy streets and try to minimize your risk of falling wherever possible.
You can talk to your doctor about medications to try, as well your surgical and homeopathic options. However, there is no cure for Parkinsons disease and no way to stop the symptoms entirely, but scientists are working to change that.
How Is Parkinson’s Disease Treated
If a doctor thinks a person has Parkinson’s disease, there’s reason for hope. Medicine can be used to eliminate or improve the symptoms, like the body tremors. And some experts think that a cure may be found soon.
For now, a medicine called levodopa is often given to people who have Parkinson’s disease. Called “L-dopa,” this medicine increases the amount of dopamine in the body and has been shown to improve a person’s ability to walk and move around. Other drugs also help decrease and manage the symptoms by affecting dopamine levels. In some cases, surgery may be needed to treat it. The person would get anesthesia, a special kind of medicine to prevent pain during the operation.

Body System #7/8: Cardiovascular/circulatory System
The circulatory system permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells. It also helps fight disease, stabilize temperature and pH, and maintain homeostasis.
Diseases and Disorders of the Circulatory System
- Cardiovascular Disease This disease comprises heart conditions that include diseased vessels, structural problems, and blood clots.
- Arteriosclerosis Fatty deposits in the arteries cause the walls to stiffen and thicken which can restrict blood flow in the body.
- Stroke A stroke is characterized by a blockage of the blood vessels to the brain.
- Hypertension Hypertension is high blood pressure that causes the heart to work harder.
- Aortic Aneurysm This is a condition in which the aorta is damaged and starts to bulge or tear causing severe internal bleeding.
- Peripheral Arterial Disease PAD is the narrowing or blockage of an artery.
- Chronic Venous Insufficiency With CVI, sections of the superficial veins of the lower extremities reflux.

What Is The Outlook For Persons With Parkinsons Disease
Although there is no cure or absolute evidence of ways to prevent Parkinsons disease, scientists are working hard to learn more about the disease and find innovative ways to better manage it, prevent it from progressing and ultimately curing it.
Currently, you and your healthcare teams efforts are focused on medical management of your symptoms along with general health and lifestyle improvement recommendations . By identifying individual symptoms and adjusting the course of action based on changes in symptoms, most people with Parkinsons disease can live fulfilling lives.
The future is hopeful. Some of the research underway includes:
- Using stem cells to produce new neurons, which would produce dopamine.
- Producing a dopamine-producing enzyme that is delivered to a gene in the brain that controls movement.
- Using a naturally occurring human protein glial cell-line derived neurotrophic factor, GDNF to protect dopamine-releasing nerve cells.
Many other investigations are underway too. Much has been learned, much progress has been made and additional discoveries are likely to come.
Tips For Caring For Someone With Parkinsons Disease
Caring for a loved one with early onset Parkinsons can be difficult. If youre a caregiver for someone with this condition, its important that you remember your own emotional and physical health.
Not only are you dealing with a difficult diagnosis, youre also managing an increased number of responsibilities. Burnout is common in caregivers, so make sure youre checking in with your own needs.
The Michael J. Fox Foundation Center for Parkinsons Research recommends these tips for caregivers:

Parkinsons Disease Is A Progressive Disorder
Parkinsons Disease is a slowly progressive neurodegenerative disorder that primarily affects movement and, in some cases, cognition. Individuals with PD may have a slightly shorter life span compared to healthy individuals of the same age group. According to the Michael J. Fox Foundation for Parkinsons Research, patients usually begin developing Parkinsons symptoms around age 60. Many people with PD live between 10 and 20 years after being diagnosed. However, a patients age and general health status factor into the accuracy of this estimate.
While there is no cure for Parkinsons disease, many patients are only mildly affected and need no treatment for several years after their initial diagnosis. However, PD is both chronic, meaning it persists over a long period of time, and progressive, meaning its symptoms grow worse over time. This progression occurs more quickly in some people than in others.
Pharmaceutical and surgical interventions can help manage some of the symptoms, like bradykinesia , rigidity or tremor , but not much can be done to slow the overall progression of the disease. Over time, shaking, which affects most PD patients, may begin to interfere with daily activities and ones quality of life.

Constipation And Digestive Issues
As Parkinsons disease progresses, your digestive tract will slow down and function less efficiently. This lack of movement may lead to increased bowel irritability and constipation.
In addition, certain medications often prescribed for Parkinsons disease, such as anticholinergics, can cause constipation. Eating a balanced diet with plenty of vegetables, fruits, and whole grains is a good first step remedy.
Fresh produce and whole grains also contain a great deal of fiber, which can help prevent constipation. Fiber supplements and powders are also an option for those with Parkinsons.
Be sure to ask your doctor how to gradually add fiber powder to your diet. This will ensure you dont have too much too quickly and make constipation worse.

What Other Things Help
There are various ways to help a person with PDD. Speech therapy may help improve communication between people with PDD and others. Physical therapy may help strengthen and stretch stiff muscles and help to prevent falls.
Research has shown that;physical exercise helps to enhance brain health and improves mood and general fitness. A balanced diet, enough sleep and limited alcohol intake are other important ways to promote good brain health. Other illnesses that affect the brain, such as diabetes, high blood pressure and high cholesterol, should also be treated if present.

Symptoms Of Parkinson’s Disease
You can attribute the symptoms of Parkinson’s to a deficiency of a chemical in your brain called dopamine.;The four classic motor symptoms of Parkinson’s include:
Shaking and tremors while you are resting is typically the first sign of Parkinson’s disease, but about one-third of patients won’t experience those symptoms. These symptoms tend to be worsened by emotional and physical stress. Sleep or moving can help reduce these issues.
Parkinson’s disease is both chronic and progressive with symptoms generally getting worse as time goes on. As it progresses, other disabilities can develop, including:
- Difficulty talking and swallowing
- A sudden inability to move,
Some sufferers also have symptoms that don’t affect their motor skills, including:
- Mental health issues such as anxiety, depression and memory loss
- Loss of smell
- Trouble sleeping, including thrashing and other sudden movements
- Change in blood pressure
What Body Systems And Organs Are Affected By Parkinson Disease
5/5Parkinsons diseasebodyorgan systemsaffectedsystem
Parkinsons disease is a degenerative, progressive disorder that affects nerve cells in deep parts of the brain called the basal ganglia and the substantia nigra. Nerve cells in the substantia nigra produce the neurotransmitter dopamine and are responsible for relaying messages that plan and control body movement.
Also, what foods should Parkinsons patients avoid? Eat too many sugary foods and drinks as these can negatively impact your immune system. Opt for naturally sweetened food and reduce your sugar intake to manage Parkinsons symptoms. Eat too much protein. Consuming lots of beef, fish, or cheese may affect the effectiveness of certain Parkinsons medications.
Just so, how does Parkinson disease affect the muscular system?
Unlike some neurological conditions which affect muscle tone, the rigidity in Parkinsons disease affects flexor and extensor muscles equally. Rigidity in Parkinsons disease can prevent you from moving easily, and this lack of easy movement can lead to more stiffness in a downward cycle.
How does Parkinson start?
PD starts with the brain cells, called neurons, which control movement. Neurons produce a substance called dopamine. PD sets in when the neurons die and the levels of dopamine in the brain decrease. Early signs of Parkinsons disease can be easy to miss, especially if they occur sporadically.

Parkinson Disease Neuropathology In The Autonomic Nervous System
Anatomically, the autonomic nervous system can be divided into central autonomic networks, sympathetic pathways, parasympathetic pathways and the enteric nervous system. Central autonomic networks integrate autonomic function, linking the neocortex, diencephalon and brainstem. At its core is the nucleus tractus solitarius which integrates somatic and autonomic nervous systems and maintains homeostasis with projections to the hypothalamus, limbic structures and descending autonomic tracts. PD pathology has been characterized by intraneuronal inclusions which contain α-synuclein known as Lewy neurites or Lewy bodies . α-synuclein is a presynaptic protein thought to maintain synaptic integrity and be involved with regulation of dopamine synthesis. Although often seen in the absence of neuronal loss, evidence suggests that α-synuclein aggregation is a precursor to neurodegeneration. PD pathology has been observed in a chain of neurons forming autonomic pathways including: the hypothalamus, preganglionic parasympathetic projection neurons in the dorsal motor nucleus of the vagus and pre-ganglionic and post-ganglionic sympathetic projection neurons . PD pathology has also been found in several end-organs including the submandibular gland, lower esophagus, duodenum, pancreas, bronchus, larynx, epicardium, adrenal medulla, parathyroid and ovary. illustrates most areas within autonomic pathways where PD pathology has been found.
