Tremor Involuntary shaking of the hands, arms, legs, jaw or tongue.


Some people report an internal tremor, a shaking sensation inside the chest, abdomen or limbs that cannot be seen. Changes in posture, walking and facial expressions occur.

Stage Two Symptoms start getting worse. Walking problems and poor posture may be apparent. The person is still able to live alone, but daily tasks are more difficult and lengthy.

Recently, first pilot studies were published for PD patients and correlated positive treatment outcomes for symptomatic pharmacological or interventional therapies with stages of parkinsons disease genotypes in candidate genes.

Parkinson's Disease Prognosis

In a first study, DNA samples from participants of the ADAGIO study that represented the largest clinical trial of early stage PD patients under monotherapy with rasagiline were genetically stratified for genetic polymorphisms from 20 candidate genes Masellis et al.

The authors found a polymorphism in stages of parkinsons disease dopamine D2 receptor gene as predictive for a meaningful clinical response to rasagiline treatment Masellis et al.

This effect was not associated with the rate of symptom progression during stages of parkinsons disease trial period. Stages of parkinsons disease study investigated the contribution of genes to the positive therapeutic outcome in PD patients treated with DBS.

The candidate genes were chosen based on the fact that both consistently found associated with PD in large GWAS studies from different populations worldwide Simon-Sanchez et al.

Interestingly, a certain allele of the alpha-synuclein polymorphism predicted a positive outcome of DBS in a dose-dependent manner with homozygous carriers showing the most pronounced benefit Weiss et al.

The same genetic variant was linked to reduced expression of the PD-associated alpha-synuclein protein in different brain areas assessed by different post-mortem studies Linnertz et al.

This may indicate that the burden of alpha-synuclein accumulation could relate to the integrity of the basal ganglia loops that are critical for effective neuromodulation.

In support of this hypothesis, the same alpha-synuclein polymorphism that was associated with reduced expression of alpha-synuclein in human stages of parkinsons disease was associated with PD without stages of parkinsons disease impairment in a recent association study on PD patients with and without dementia Guella et al.


This further supports the concept of genetic variants in the alpha-synuclein gene as potential tools for stratification in clinical trials. The previous findings on pharmacological or neuromodulation therapy still require validation in independent cohorts, which are difficult to find due to the clinically well-characterized cohorts that served as starting stages of parkinsons disease for the pilot studies and, therefore, should stimulate efforts for deep phenotyped patient cohorts for translational research.

These cohorts will be also critical for the development of clinical trials that focus more on individual not average therapeutic response. Current medications provide efficacy only in a subset of patients, e. The underlying clinical trials collected a handful of parameters stages of parkinsons disease a large number of study participants.

End-Stage Parkinson’s: What to Expect

The latter are frequently observed in PD as advanced stages in patients with stages of parkinsons disease advanced age currently imply polypharmaceutical approaches.

Practical aspects for the implementation of advanced treatments In the past few years, the treatment of PD has become stages of parkinsons disease complex and it is expected to be more individualized in the future, which implies novel strategies for best practices to define and convey best treatment options to patients with advPD.

Current guidelines are a helpful tool in the diagnostics and therapeutic decision making in the early stages of disease; however, there is not enough reliable information on how to implicate the suggested strategies in the everyday neurological practice.

In addition, there is little specific information on possibilities of influencing the course of disease progress.

In addition to the usage of the oral medication in the early stages of parkinsons disease of the disease, there has been an increase in application of the interventional therapies such as deep brain stimulation and pump therapies.

These highly specific treatment options are mostly implemented in specialized clinics or practices for movement disorders. Here, the optimal timing for initiating advanced therapies to improve the quality of life and prevent complications is critical and requires an early information of patients and caregivers about the later stages of the disease with its complications.
