The population with PDP and increasing efficiency in diagnosis coupled with longer Ephesians pose a potential burden on the individuals and health care system for their cumulative costs. There are four hallmark motor symptoms of PDP: 1) resting tremor, 2) braininess, 3) rigidity with “cogwheel” properties, and 4) unstable posture (8). These symptoms may not be found in all individuals, though most do occur at some point throughout their life with postural instability typically occurring last. All symptoms are bilateral though they first exhibit themselves on one side of the body and become apparent in the other as PDP further develops.

The side where symptoms were first pronounced onetime to be more affected than the other side (5). ! Symptoms are paramount to the diagnosis of PDP. A resting tremor is the most frequently These occurring early presentation of PDP (5), typically found In the patients thumb or wrist. Resting tremors can also be seen in the legs or oral region (chin, lips, Jaw) and Infrequently involve the neck or head (7). Suppuration-probation “Pill-rolling” Is a feature of this tremor causing a circular motion between the Index finger and thumb approximately 4-6 times per second (3).

This tremor Is usually apparent during times of rest and absent with voluntary movement or sleep. Individuals may have a long history of tremors before the Parkinson tremor manifests. Postural tremors also occur In PDP patients which present Like an essential tremor. These tremors can also be the first Indications of PDP which are severely disabling (3). These tremors are the easiest recognizable trait of PDP. Continued and Due excessive contractions of muscle cells because of their tremor or otherwise cause an increase in muscle tone resulting in stiffness and inability to move their Joints (7).

In addition to pain from their resting tremor the resulting stiffness is another early indicator of PDP, most frequently found in the shoulder. When these limbs are moved by another individual a “cogwheel rigidity’ (difficult movement initially, then a period of less resistance repeating) is often noted (8). This rigidity may be found in the wrists, ankles, neck, shoulder, or hips. Studies found that the presence of stiffness were associated with increased development of PDP (8). Braininess is the slowness of movement, a common clinical trait in which PDP causes.

This is the most common symptom of basal ganglia disorders which causes difficulty in numerous aspects of planning movement through its execution (8). These symptoms first appear in daily activities and decreased reaction times. Further development of braininess causes increased difficulty with fine motor skills (egg, tying shoes, penmanship) (7). Changes in the ability to swallow cause an individual to drool accompanied by lack of facial expression. Of all signs and symptoms of PDP, braininess is best explained by dopamine deficiency (8).

Braininess is not consistent as it depends heavily on the individuals emotional state or activity being performed (egg, ability to ride a bike and unable to walk). When a PDP patient is excited or something (egg, seeing a grandchild or old friend) their excitement often supersedes braininess symptoms and are able to move at a faster pace. ! Instability is caused by the destruction of postural reflexes which typically present after Postural other clinical indications of PDP. This instability is often the cause of falls, resulting in fractures for these PDP patients (8).

Given the typical age of PDP patients these falls are a significant health risk. Tests for postural instability are conducted to determine the progression of the disease. A PDP patient will be quickly lulled forward or backward to access the degree to which the individual needs to respond (how many steps forward or backward to correct) (7). Instability is also caused by other common disease factors; orthodontic hypertension, or changes in cognition (8). The instability is infrequent in the younger PDP population and increases with age (thought to be associated with normal loss of balance).

Postural instability is used to test for Pad’s progression. ! Are many other symptoms of PDP which are not related to motor function. Cognitive There memories, though cues of memories aids their recall (6). PDP patients are six times more likely to develop dementia with its incidence increasing after 75 years of age (3). Depression is the most common non motor symptom of PDP affecting 50% of patients often combined with anxiety (4). Impulse control disorders are more frequently recognized in patients with PDP relating to gambling, eating, sexual behavior, or buying (3).

Hallucinations and delusional thought processes can also be seen in PDP patients. Psychosis is often related to dopamine therapy (5). Sleep disorders are also common, though the influence could be contributed to their medications. Insomnia, alterations in ERM cycles, and excessive daytime somnolence are the typical manifestations. These non motor symptoms of PDP can influence the life expectancy of the PDP patient (6). In some cases these symptoms can overshadow the motor disabilities making a diagnosis more difficult. The primary cause of PDP has not been found, though there are many risk factors that have been identified.

As mentioned previously, incidences of PDP increase with age mostly after 60. Additionally, males are more likely to get PDP than females the reasoning may be due to environmental exposure to toxins or a possible X-Inked impotent to the disease (8). Though females who do not use hormone replacement therapy are at greater risk. Another genetic link is through a-cuisine in which the carriers of the gene are 1 . Xx more likely to develop PDP (1). There have been some connections supporting the genetic predisposition to PDP if one or more immediate relatives have PDP.

Environmental toxins that inhibit dopamine production or initiate free radicals within the body are also believed to be a cause of PDP, often years after exposure (8). Head trauma has also been linked to PDP with upper cervical damage u to these injuries (7). Though there are many risk factors PDP is not well understood. There are many people who align with multiple risk factors and never develop PDP. This goes to show the amount of research needed in order to develop a further understanding of PDP to connect with prevention.

Parkinson disease is noted by the degeneration of dopamine producing neurons. Dopamine is a neurotransmitter in the brain that is involved in rewards and pleasure, many addictive drugs simulate its effects. Dopamine is an organic catecholamine chemical, produced in the basal ganglia and of which epinephrine ND morphogenesis are made from the dopamine base. Degeneration is found in the basal ganglia’s substantial Niagara and dorsal stratum where a-cuisine point mutations or misfiles decreases dopamine production (8).

This results in uncontrolled excitatory or inhibitory flow in the basal ganglia. Dopamine moderates and individuals response by moderating the amount of effort needed to achieve an action. The decreased amounts of dopamine in PDP patients create an atmosphere However, with a large stimulus of the sympathetic nervous system an action can easily be achieved. Changes to the a-cuisine production varies in the individual with PDP (2); younger patients degradation of the substantial Niagara occurs over a longer time period than older patients (2).

These differences are believed to be the difference of dementia’s onset between the different age classes. Remaining neurons are often taken over by Eely bodies which accumulate abnormal proteins in the neurons. Each of these factors contributes to the hallmark attributes of PDP (3). These appear after most of the degradation to dopamine production and are required for the clinical diagnosis of PDP (3). The formation of Eely bodies is not limited to the basal ganglia and occur in the diminishable, spinal cord, and unescorted.

The accumulation of a-cuisine as an insoluble fibril is the primary protein within the Eely body in addition to synthesis, another protein associated with a-cuisine (8). The presence of asininely is also found in Eely body Alchemies patients that is one of the key overlaps between the two diseases. These bodies are spherical masses that compromise other cellular components further reducing the original function of the cell. Sadly there is no cure for PDP at this time. Numerous forms of treatment are available that can reduce the symptoms, yet not the progression of the disease (1).

There are many options ranging from over-the-counter medications to surgical procedures. Treatment will often encompass many medications that either directly affect symptoms or are designed to make other medications more effective. Many PDP patients find it difficult to follow their prescriptions due to their quantity and cognitive defects associated with PDP (7). Most treatments look to stimulate remaining dopamine production or enhance the bodies use of its remaining dopamine. Progression of PDP often lessens the treatments affects and becomes more difficult to treat. Most common treatment of PDP is administration of leopard (L-DOPE), the precursor of The catecholamine (7). L-DOPE has the ability to cross the blood-brain barrier where its presence helps the remaining cells of the basal ganglia produce dopamine (5). Synthetic dopamine or treatment with dopamine itself is not a beneficial treatment as it cannot cross the blood-brain barrier. L-DOPE is converted into dopamine by aromatic L-amino acid destroyable with vitamin 86 as a cofactor (5). Pyridoxine is happily administered with L-DOPE to provide 86 and facilitate optimal dopamine production.

L-DOPE is commonly prescribed as Sentiment or Tame which combines L- timeline in which this medication is most effective, though most neurologists suggest earlier treatment. Prolonged use and increasing doses can cause adverse side effects and the loss of effectiveness. ! From L-DOPE medications the other main prescriptions are dopamine Zionists, Aside intercollegiate, MAO-B and COM inhibitors. Dopamine Zionists stimulate dopamine susceptible areas of the brain which causes the cells to activate as they would under dopamine (1).

These drugs are not as potent as the L-DOPE medications with decreased incidences of duskiness. Pomeranian is a fast-acting dopamine agonies lasting 30 to 60 minutes relieving PDP symptoms typically used when other medications lose effectiveness (1). Anticlericalism are used to aid tremors and distortion liked to other medications effects and have few effects on PDP symptoms (5). MAO-B and COM inhibitors are used in conjunction with L-DOPE to moderate its breakdown within the brain (5). These allow for decreased doses and more effective use of L-DOPE medication and have no direct effect on PDP symptoms. Reoccurred for PDP consist of deep brain stimulation (DB’S) that helps control PDP Surgical symptoms and improve the patient’s quality of life (5). Electrical stimulation of the brain is directed by electrodes placed into the brain while under MR. to target specific areas. DB’S is best use to treat PDP patients with tremor, rigidity, and braininess as their primary symptom (5). The area of the brain stimulated by DB’S is subject of the patients symptoms and desired outcome. Like all surgeries there is a possibility of complications, predominantly hemorrhaging and infection (1).

DB’S is he most recent treatment for PDP and progress continues towards more effective treatment and prevention. Parkinson Disease is better documented and understood than ever before. The multicultural and undocumented cause of PDP also contribute towards it’s increasing research. PDP in the United States was most publicly brought into the spotlight when actor Michael J. Fox was diagnosed in 1991 and didn’t make it public until 1999. His foundation and others have furthered the research and spread of information regarding this life changing disease. Hopefully their research will provide greater insight to the incidence of PDP.
