Clinical Terms For Parkinsons Disease
Parkinson Disease-. A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion , rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition characterized by dementia in combination with varying degrees of parkinsonism.

Support For Revision Of Icd
The American Academy of Neurology supports the need to update the ICD-10-CM coding to better reflect the progression of PD. Patient advocacy groups also support this need, including the Michael J. Fox Foundation for Parkinsons Research and the Unified Parkinsons Advocacy Council , which is a group of national, regional, and state organizations including the Parkinsons Foundation, the American Parkinson Disease Association, and the Davis Phinney Foundation for Parkinsons among others.
Potential Biomarkers Of Pd Psychosis
A biomarker is defined as a characteristic that can be objectively measured and that can indicate a normal biological process, a pathogenic process, or a pharmacologic response to a specific therapy . Biomarkers can range from clinical, neuroimaging, and biochemical to genetic or proteomic characteristics and their purpose can be to confirm a diagnosis, serve for epidemiological screening, predict an outcome, monitor disease progression, or assess and predict response to a treatment. In the thorough search for a therapy for PD in the past 30 years, next to the complexity of the disease itself, the lack of reliable tools available to monitor progression and to observe the effects of the interventions has been a major drawback. Screening for biomarkers in PD is therefore highly relevant, but no reliable ones are readily available . To this purpose, the PPMI is currently undergoing an observational, multicentre, international study designed to evaluate potential biomarkers of PD progression comprising 400 recently diagnosed PD patients and 200 healthy subjects among a total of 21 centres .

Measurement Of Telomere Length
Forero et al stated that differences in telomere length have been reported as possible risk factors for several neuropsychiatric disorders, including PD. Results from published studies for TL in PD are inconsistent, highlighting the need for a meta-analysis. In the current work, a meta-analysis of published studies for TL in PD was carried out. PubMed, Web of Science and Google Scholar databases were used to identify relevant articles that reported TL in groups of PD patients and controls. A random-effects model was used for meta-analytical procedures. The meta-analysis included 8 primary studies, derived from populations of European and Asian descent, and did not show a significant difference in TL between 956 PD patients and 1,284 controls . The authors concluded that the findings of this meta-analysis showed that there is no consistent evidence of shorter telomeres in PD patients and suggested the importance of future studies on TL and PD that analyze other populations and also include assessment of TL from different brain regions.
Abnormality Of Tau Protein
PSP has been considered to be a tau protein disorder. Cortical fibrillary tangles of PSP are similar to those observed in Alzheimer disease with regard to the presence of an abnormally phosphorylated tau protein. Tau is a component of a microtubule-associated protein that is responsible for axonal transport of vesicles. The mechanism whereby this is involved in PSP has yet to be determined. PSP overlaps with corticobasal degeneration in this regard, and the latter may have a stronger association with tau protein abnormalities than does PSP.
Tau proteins exist in 6 isoforms encoded by a single gene. Different electrophoretic patterns have been identified in the various disorders associated with tau abnormalities. Thirty-two mutations have been identified in more than 100 families. About half of the known mutations have their primary effect at the protein level. They reduce the ability of tau protein to interact with microtubules and increase its propensity to assemble into abnormal filaments. The other mutations have their primary effect at the RNA level and perturb the normal ratio of 3-repeat to 4-repeat tau isoforms. When studied, this change resulted in a relative overproduction of tau protein with 4 microtubule-binding domains in the brain.

Dementia With Lewy Bodies
Dementia with Lewy bodies is named for the presence of abnormal protein deposits of alpha-synuclein that are also seen in people with PD. DLB is the second most common type of dementia after Alzheimers disease, and it is a progressive disorder. In people with DLB, the Lewy bodies are found throughout the brain. DLB is characterized by cognitive impairments, visual hallucinations, inability to focus, inflexible thinking and paranoia. DLB patients initially have these cognitive symptoms but also develop motor symptoms similar to PD such as bradykinesia, tremor, rigidity, and shuffling walk. Similar to PD, DLB patients also have REM sleep behavior disorder in which they act out their dreams. DLB is treated with cholinesterase inhibitors and atypical antipychotics. However, there is no cure for DLB.

What Are The Symptoms Of Atypical Parkinsonian Disorders
Like classic Parkinsons disease, atypical Parkinsonian disorders cause muscle stiffness, tremor, and problems with walking/balance and fine motor coordination.
Patients with atypical Parkinsonism often have some degree of difficulty speaking or swallowing, and drooling can be a problem. Psychiatric disturbances such as agitation, anxiety or depression may also be part of the clinical picture.
Dementia with Lewy bodies can cause changes in attention or alertness over hours or days, often with long periods of sleep during the day. Visual hallucinations typically of small animals or children, or moving shadows in the periphery of the visual field are common in DLB. DLB is second only to Alzheimers disease as a cause of dementia in the elderly, and it most commonly affects patients in their 60s.
Patients with progressive supranuclear palsy may have difficulties with eye movements, particularly when looking downward, and with balance when descending stairs, for instance. Backward falls are common and may occur during the early course of the disease. PSP is not usually associated with tremor, unlike Parkinsons disease.

Parkinsons Disease Vs Parkinsonism: Understanding The Difference Is Essential For Icd
March 25, 2019 / By Pamela Ewing, CPC
What is Parkinsons disease? It is a neurodegenerative disorder that affects predominately dopamine-producing neurons in a specific area of the brain called the substantia nigra.
The substantia nigra cells produce dopamine, a chemical messenger responsible for transmitting signals within the brain that allow for coordination of movement. Loss of dopamine causes neurons to fire without normal control, leaving patients less able to direct or control their movement. Parkinsons disease is one of several diseases categorized by clinicians as movement disorders.
Parkinsons disease has four main symptoms:
- Tremor in hands, arms, legs, jaw, or head
- Stiffness of the limbs and trunk
- Slowness of movement
- Impaired balance and coordination
Parkinsonism refers to symptoms of Parkinsons disease , regardless of the cause, and is typically caused by another condition or external agent, such as drugs. These two conditions are not classified the same.
With the Parkinsons Disease progression listed are just a few of many symptoms. Some symptoms may include, but are not limited to:
specified NEC E21.4Parkinsons G20
We then look in the Alpha index for Parkinsons and it refers us to Parkinsonism.
Parkinsonism G20with neurogenic orthostatic hypotension G90.3arteriosclerotic G21.4dementia G31.83 with behavioral disturbance G31.83
G20 would be used to indicate Parkinsons Disease, and it would be sequenced first, followed by the manifestation.

Premotor Versus Late Occurring Pd Psychosis
To our knowledge only one study has been performed and recently published to analyze the presence of psychotic symptoms as a feature of the premotor state of PD Pagonabarraga et al. studied a cohort of 50 drug-naïve PD patients and compared them with 100 healthy controls to assess the presence of hallucinations . They found an overall prevalence of minor hallucinations in the untreated PD group of 42%, the onset of these being 7 months to 8 years prior to motor symptom onset. The prevalence of hallucinations in the control group was 5%. When comparing the cohort of PD patients and healthy controls, the groups did not differ in baseline characteristics, apart from a significant impairment in global cognitive function in the PD group compared with the control group. Nonetheless, dementia criteria were not met in any of the subjects included in the study. When then comparing the PD patients with and without hallucinations, older age and the presence of rapid-eye-movement behaviour disorder were statistically significantly correlated as seen in Table 4. This preliminary study sheds light on a potential prodromal occurrence of PD psychosis and proposes risk factors that could help recognize at-risk PD patients. Further studies with wider sample sizes are nonetheless needed.
General Psychosis And Pd Psychosis
With regard to the clinical definition of the main features of psychosis, which include hallucinations, illusions, and delusions, current ICD-10 guidelines define hallucinations as a disorder characterised by a false sensory perception in the absence of an external stimulus, whereas an illusion is regarded as a misperception of an externally present stimulus. In contrast to classical hallucinations and illusions, delusions are a false interpretation of the experienced misperceptions, often involving topics of persecution, imposters, or grandiosity. Some specific forms of delusions such as the Cotard syndrome , Capgras syndrome , and Othello syndrome have further been named , the latter showing an association with dopamine agonist therapy and an improvement after its reduction. The current diagnostic criteria from ICD-10 based guidelines for acute and transient psychosis are shown in Box 1 other definitions of psychosis falling under the term of schizoaffective disorders will not be further developed in this review.

Associated Complications Of Pd
There are quite a few associated complications of Parkinsons disease, and dementia is one of them. Therefore, if the documentation indicates the patient has dementia secondary to Parkinsons disease, it would be reported as:
- G20, Parkinsons disease
- F02.80, Dementia in other diseases classified elsewhere without behavioral disturbance
To find these codes, we can look under dementia and go down the list to in , and Parkinsons disease G20 . This means the code in brackets is a secondary code and must be reported after the code for the underlying condition . Parkinsons is the underlying cause, and dementia is the manifestation of the Parkinsons.

What Are Atypical Parkinsonian Disorders
Atypical Parkinsonian disorders are progressive diseases that present with some of the signs and symptoms of Parkinsons disease, but that generally do not respond well to drug treatment with levodopa. They are associated with abnormal protein buildup within brain cells.
The term refers to several conditions, each affecting particular parts of the brain and showing a characteristic course:
- Dementia with Lewy bodies, characterized by an abnormal accumulation of alpha-synuclein protein in brain cells
- Progressive supranuclear palsy, involving tau protein buildup affecting the frontal lobes, brainstem, cerebellum and substantia nigra
- Multiple system atrophy, another synucleinopathy that affects the autonomic nervous system , substantia nigra and at times the cerebellum
- Corticobasal syndrome, a rare tauopathy that typically affects one side of the body more than the other and makes it difficult for patients to see and navigate through space

Measurement Of Urinary Lrrk2 Phosphorylation
Fraser and colleagues examined if phosphorylated Ser-1292 LRRK2 levels in urine exosomes predicts LRRK2 mutation carriers and non-carriers with Parkinson disease and without Parkinson disease . LRRK2 protein was purified from urinary exosomes collected from participants in 2 independent cohorts. The 1st cohort included 14 men . The 2nd cohort included 62 men . The ratio of Ser-1292 LRRK2 to total LRRK2 was compared between LRRK2+/PD+ and LRRK2- in the 1st cohort and between LRRK2 G2019S carriers with and without PD in the 2nd cohort. LRRK2+/PD+ had higher ratios of Ser-1292 LRRK2 to total LRRK2 than LRRK2-/PD- and LRRK2-/PD+ . Among mutation carriers, those with PD had higher Ser-1292 LRRK2 to total LRRK2 than those without PD . Ser-1292 LRRK2 levels predicted symptomatic from asymptomatic carriers with an area under the receiver operating characteristic curve of 0.844. The authors concluded that elevated ratio of phosphorylated Ser-1292 LRRK2 to total LRRK2 in urine exosomes predicted LRRK2 mutation status and PD risk among LRRK2 mutation carriers. Moreover, they stated that future studies may explore whether interventions that reduce this ratio may also reduce PD risk. In particular, they stated that larger studies that measure Ser-1292 LRRK2 levels over time in asymptomatic carriers will be needed to understand the prognostic potential of this new biomarker.
