Assessment For Parkinson’s Disease

Development Of The Spes/scopa

Approach to the Exam for Parkinson’s Disease

The SPES/SCOPA consists of three sections: MI, ADL, and motor complications. There are four response options ranging from 0 to 3 . In comparison with the original SPES, some modifications to the three sections were made based on findings in the literature and empirical testing of some of the items. The mental section was removed altogether because we felt that these important functions could not be assessed in a reliable and valid way by a few single questions as a part of the SCOPA project, we tested and developed separate instruments for these functions.

Motor impairments

Activities of daily living

The response options were framed as uniformly as possible. Responses reflected no difficulty , some difficulty , considerable difficulty , and unable . As stated before, swallowing was removed. Turning and getting out of bed was extended to changing positions to include all important transfers of daily life. The maximum score in this section is 21.

Motor complications

The Role Of Aesthetics And Design For Acceptance And Adoption

From healthcare professionals point of view, wearable devices would be acceptable to most patients, particularly young patients. Device visibility may depend on the stage of the disease healthcare professionals believed patients in more complex stages of PD would be more likely willing to wear visible devices than would newly diagnosed patients.

So, it depends on what stage of Parkinsons you are talking about. So, if you are going to go to somebody newly diagnosed, they probably want something pretty discreet. But somebody who is in the more maintenance, more complex phase they may wear something that is a bit more visible.

Device design is one of the most important factors that determine whether patients are willing to wear the device. In line with previous studies healthcare professionals felt that the device must be comfortable, easy to use, non-invasive, and should easily be worn under clothes without catching/snagging. The device should also be water-resistant, washable, durable, and easy to fasten to minimise daily disruption.

It is quite expensive. They do use it,inhe uses them a bit because he is doing, um, he has access to very expensive treatment and so he wants very objective data to give them the expensive treatment The software that they have developed to interpret the device finding is quite complicated

If it is designed to do with Parkinsons and in time people got to know if they saw that on you, you got Parkinsons, he might need help

Parkinsons Disease NCLEX Review and Nursing Care Plans

Parkinsons Disease is a common neurodegenerative disease characterized by changes in movement and posture.

It is a progressive illness with symptoms starting from barely noticeable to obvious signs and symptoms.

Tremors, rigidity, and bradykinesia are the triad of symptoms of Parkinsons disease.

Parkinsons disease has a prevalence rate of 0.5-1% in the 65-69 years old population. Its occurrence rises as the age progresses and its incidence is second to Alzheimers disease.

Continuous Monitoring In Daily Activities

Monitoring motor function of PD patients during real life activities could provide physicians with an assessment of specific motor symptoms, predict fall risk, evaluate medication compliance and provide information for early diagnosis.

Unlike guided and standardized motor tasks, motor assessment in unsupervised environment allows subjects to moving in daily activities, which means that two subjects can walk with different motion parameters not because of disease itself but due to individual differences . A fully charged measuring device such as portable gait rhythmogram could achieve 40 consecutive hours of recording . With this PGR attached to the limbs, different motor fluctuations were observed according to the alterations in gait rhythm: if a subject was noted with a shift to a faster gait cycle, he/she may suffer from short-step walking, festination or freezing of gait on the other hand, if a subject was found to exhibited a shift to a slower gait cycle, there was high possibility that he/she had bradykinesia or instability . On the other hand, some researchers thought that parameters regarding the gait performance were not representative enough and the utilization of alternative measures like entropy or the measure of the arm swing might be a better choice . In presenting variation in ON and OFF states, arm swing and entropy showed better performance compared to step frequency, stride length and speed .

Physical Exam For Parkinson’s

Parkinson

During a physical exam, the doctor examines the patients body for signs of disease. The doctor will include a visual inspection , palpation , ascultation , and percussion . The physical exam for PD is generally conducted by a neurologist and may also be called a neurological exam. It is recommended that a patient see a neurologist with special training in movement disorders as these specialists have the most knowledge about the symptoms and medications. During a neurological exam, the patient may be asked to sit, stand, walk, and extend their arms as the doctor evaluates balance and coordination. Most neurologists recommend a spouse or caregiver attend the exam with the patient to help with answering important questions.1,2

Is Early Diagnosis Possible

Experts are becoming more aware of symptoms of Parkinsons that precede physical manifestations. Clues to the disease that sometimes show up before motor symptoms and before a formal diagnosis are called prodromal symptoms. These include the loss of sense of smell, a sleep disturbance called REM behavior disorder, ongoing constipation thats not otherwise explained and mood disorders, such as anxiety and depression.

Research into these and other early symptoms holds promise for even more sensitive testing and diagnosis.

For example, biomarker research is trying to answer the question of who gets Parkinsons disease. Researchers hope that once doctors can predict that a person with very early symptoms will eventually get Parkinsons disease, those patients can be appropriately treated. At the very least, these advances could greatly delay progression.

Subanalyses And Ablation Studies

Performance dependence on model subcomponents

Our AI model employs multitask learning and transfer learning . We conducted ablation experiments to assess the benefits of the qEEG auxiliary task, and the use of transfer learning. To do so, we assessed the AUC of the model with and without each of those components. The results show that the qEEG auxiliary task is essential for good AUC, and transfer learning further improves the performance .

Comparison with machine learning baselines

We compared the performance of our model with that of two machine learning models: a support vector machine model, and a basic neural network that employs ResNet and LSTM but lacks our transfer learning module and the qEEG auxiliary task. The results show that both SVM and the ResNet+LSTM network substantially underperform our model .

Determining Diagnosis Through Response To Parkinsons Medication

Assessment – Gait – Parkinsonian Gait Demonstration

If a persons symptoms and neurologic examination are only suggestive of Parkinsons disease or if the diagnosis is otherwise in doubt, the physician may, nevertheless, prescribe a medication intended for Parkinsons disease to provide additional information. In the case of idiopathic Parkinsons, there is typically a positive, predictable response to Parkinsons disease medication in the case of some related Parkinsonian syndromes, the response to medication may not be particularly robust, or it may be absent entirely.

Unfortunately, there are no standard biological tests for the disease, such as a blood test. However, researchers are actively trying to find biomarkers in blood and other bodily fluids that could help confirm the diagnosis.

How Parkinsons Disease Is Diagnosed

Parkinsons disease is usually diagnosed clinically, meaning that a physician looks for the presence or absence of the possible symptoms of Parkinsons disease by interviewing the patient and performing a detailed neurologic examination.

While there is presently no definitive test for Parkinsons, it can often be identified by a general neurologist, who is trained to diagnose and treat neurologic disorders. To avoid misdiagnosis, consultation with a movement disorder specialist is recommended. A movement disorder specialist is a physician who has undergone additional, subspecialty training in the diagnosis and treatment of movement disorders, such as Parkinsons, after training in general neurology.

What to expect during your visit with a physician

Typically, a trained physician will only consider the diagnosis of Parkinsons disease if the person being examined has at least two of the core motor symptoms of Parkinsons, including tremor, the characteristic bradykinesia , or rigidity. At the end of your visit, the physician should discuss with you why you may or may not have Parkinsons disease and the level of certainty about the diagnosis. This determination is based on your medical history and examination at this visit.

Age And Gender Effect

In order to examine if age and gender had any effect on the FinalScore, a linear regression analysis was performed between the and the Timed , since these metrics have exhibited the highest absolute correlation with the corresponding UPDRS Part III Items . The linear regression analysis has resulted, for all cases, in p> 0.05 values, i.e., . These results clearly indicate that the proposed metrics are not affected by the age and gender of the PD patient.

User Interface Of The Assessment Tests

The setting of the user interface of the Assessment Tests of the iPrognosis Games environment is depicted in Figure 2. As it is clear from the latter, it is possible to select one of the six aforementioned motor Assessment Tests out of a dropdown menu and push play button , in order to view the corresponding tutorial video. Moreover, while PD patients watch the videos, they can synchronously perform the selected Assessment Test and receive an instant, real-time, evaluation after its completion . The UI of the motor Assessment Test presents the user’s performance on the right side and the expert’s performance on the left, so the players can easily synchronize their movement along with the expert’s and detect misfires .

Assessment Tests Motor Score Calculation

FUNCTIONAL ASSESSMENT OF PARKINSON

For the evaluation of the patient’s performance, the iPrognosis Assessment Tests environment analyzes the movement/action of the PD patient and estimates an assessment Motor Score related to the metrics/features of each Assessment Test. More specifically, the skeletal data of the user are initially estimated and then normalized to be independent of the user’s height and/or his/her position from the MentorAge® sensor. For each out of six Assessment Tests of the iPrognosis Games, two types of joints are selected in order to perform a comparison between the performance of the PD patient and the recorded experts’ performance . For each Assessment Test performance, three parameters of movement are taken into consideration regarding the selected joints, namely, Accuracy, Speed, and Angle. These were selected so as to extract clinically interpretable indices based on the clinical routine followed by the clinicians during the UPDRS Part III items marking they actually are focused on speed, halts, hesitations, and amplitude variations of each movement. All the latter are reflected in the way accuracy, speed, and angle are used and incorporated in the final score, as explained below. Moreover, the selection of only those specific parameters offered to the patients substantial indications on how to improve themselves in future efforts, and at the same time, not overwhelm them with information.

Use Of Rating Scales For Screening For Parkinsonism

Although the UPDRS was not developed for diagnostic use, it has been applied for mass screenings for parkinsonism . Note the use of the term parkinsonism rather than PD. Parkinsonism refers to the clinical manifestations, but makes no specific inference regarding the pathophysiology or etiology of the condition. Thus, these types of mass screenings attempt to identify the more general condition parkinsonism that may include drug-induced parkinsonism, multisystems atrophy, or progressive supranuclear palsy, as well as Parkinson disease. Furthermore, ratings on the UPDRS can reflect nonparkinsonian conditions. A hemiparesis due to a stroke may enhance or produce bradykinesia in a limb that is not distinguished from parkinsonism on the rating scale. Nevertheless, there have been several attempts to use modified forms of UPDRS subscale 3 as a screening for parkinsonism . In fact, mass screenings can include blinded videotape-based ratings that exclude assessment of rigidity, since that must be done in person. The key feature is to determine what value of UPDRS subscale 3 indicates parkinsonism. A score of nine on subscale 3 has been demonstrated to have 100% sensitivity and 81% specificity in identification of parkinsonism in a large video-based screening of more than 2000 people with welding exposure, an environmental factor under investigation for its potential relationship to the development of parkinsonism.

Evaluation Of Qeeg Prediction From Nocturnal Breathing

Finally, since our model predicts qEEG from nocturnal breathing as an auxiliary task, we evaluate the accuracy of qEEG prediction. We use the SHHS, MrOS and MGH datasets, which include nocturnal EEG. The results show that our prediction can track the ground-truth power in different qEEG bands with good accuracy .

Likely no. There is no need for DaTscan when your history and exam suggest Parkinsons disease and you meet the diagnostic criteria. Occasionally, if signs and symptoms are mild or you dont meet the diagnostic criteria, your doctor will refer you for a DaT scan. Keep in mind that ultimately the diagnosis is based on your history and physical exam. The DaT scan is most commonly used to complete the picture and is not a test for a diagnosis.

Assessment Of Symptomatic Effects

Ratings such as the UPDRS, either in its entirety or with motor subscale 3 alone, have been used to assess symptomatic benefit from therapeutic interventions. A critical factor in longitudinal studies is to try to control the variables in the temporal responses to individual doses of medication. Ideally, repeated ratings should be done at the same time of day, at the same time after the last dose of medication, and by the same rater. Other factors also may influence these ratings, such as diet, fatigue, or other potential stresses that may alter PD manifestations.

New Diagnostic Standards For Parkinsons

Until recently, the gold-standard checklist for diagnosis came from the U.K.s Parkinsons Disease Society Brain Bank. It was a checklist that doctors followed to determine if the symptoms they saw fit the disease. But thats now considered outdated. Recently, new criteria from the International Parkinson and Movement Disorder Society have come into use. This list reflects the most current understanding of the condition. It allows doctors to reach a more accurate diagnosis so patients can begin treatment at earlier stages.

Causes Of Parkinsons Disease

Parkinsons disease is an idiopathic illness, which means that its cause is unknown.

The signs and symptoms it present are caused by the loss of nerve cells in the part of the brain called substantia nigra.

This part of the brain is responsible for the production of dopamine, a neurotransmitter that links the brain and nervous system to coordinate body movements.

Loss of dopamine results in uncoordinated body movements, thereby producing the signs and symptoms of the disease.

Though the exact cause of Parkinsons disease is still unknown, there are possible explanations that may be responsible for the condition, such as:

  • Genetics. Studies have shown that a minority of cases of PD have genetic involvement.
  • Environmental factors. Exposure to pesticides, herbicides, and industrial pollution is now being looked at as a possible cause of PD. However, the results are still inconclusive.
  • Presence of Lewy bodies. Lewy bodies are clumps of substances in the brain cells. These are often seen in people with Parkinsons disease. The studies about them are still inconclusive, but researchers believe that these substances hold useful information to what causes PD. Researchers are also focusing into alpha-synuclein found in the Lewy bodies.

The following are the associated risk factors in developing Parkinsons disease:

Details Of The Machine Learning Baselines Used For Comparison

Pin on Parkinson

We compared our model to the following machine learning baselines:

  • We considered Support Vector Machine , which is used widely in the medical literature. SVM can be used for both classification and regression tasks. Since the input breathing signal is a time series, as common with SVM, we use principal component analysis to reduce the input dimension to 1,000.

  • We also considered a basic neural network architecture that combines ResNet and LSTM. Such an architecture has been used in past work for learning from physiological signals. The ResNet blocks use 1D convolution to encode the high-dimensional breathing into fixed-length feature vectors, which are then passed to LSTM modules for temporal understanding. The output of the network consists of two branches, one for PD detection and another for MDS-UPDRS prediction.
