The motor impairment produced by Parkinson's disease (PD) is a significant and debilitating part of the condition. Current methods to evaluate this impairment rely on subjective examinations. The investigators seek to develop an objective assessment of motor deficits by monitoring the participants natural interactions with a keyboard (on a computer or smart device). This approach provides a window to how the brain behaves during typical daily use of these devices, i.e. writing a report, sending an email or any other task performed on a digital device and thus has the potential to be used easily and regularly. (Importantly, the data gathered are non-sensitive and based only on timing information).
PD participants will be recruited during outpatient visits to PD clinics throughout the Madrid metropolitan region. General entry criteria will be those patients who are scheduled to begin dopaminergic therapy, and own a home computer or laptop. The study will not impact on participants' standard clinical management other than by asking the participants to type for 15 minutes at each of the clinic visits, and installing the investigators proprietary software on their home computer. This software will collect keystroke data alone. (None of the actual information about what is being typed will be collected.) The keystroke data collected will be analyzed and compared with standard clinical metrics of therapeutic response, as well as the in-clinic typing data.

|Official Title:||Motor Response to Dopaminergic Therapy in a Population of de Novo Parkinson's Disease Cases Quantified Via Typing Analyses - -neuroQWERTY|

A sample of 30 healthy volunteers will be recruited to compare the typing signal with that of the cases.
Early Parkinson's disease cases
A sample of 30 early PD cases (i.e. less than five years of disease and no axial signs or fluctuations) that are going to be prescribed de novo dopaminergic therapy will be recruited.
- Percentage of participants with a motor response to medication > 4 UPDRS-III points detected by the developed algorithm (sensitivity to a motor change). [ Time Frame: 24-weeks ]A diagnostic table will be computed with all the study subjects. Those subjects with a clinical relevant response to medication (> 4 points in UPDRS - III) will be considered as true positives. Then, the accuracy of the typing test to detect them will be evaluated. For this purpose, the sensitivity, specificity, predictive values and ROC curve of a classification algorithm based on our nQ index will be computed. This will allow us assessing the validity of the test to identify a motor change. detected by the developed algorithm (sensitivity to a motor change).
- Agreement between nQ and UPDRS motor subscale [ Time Frame: 4,8,16,24-weeks ]Correlation (Spearman Rho) analyses between the indices and UPDRS
- Comparison between nQ and the different motor tests (Purdue Pegboard test score & Alternating Finger Tapping) [ Time Frame: 4,8,16,24-weeks ]Correlation (Spearman Rho) between the indices and motor test scores
- Effect of dopaminergic medication measured by nQ [ Time Frame: 4,8,16,24-weeks ]Correlation (Spearman Rho) between the indices and drug titration measured in L-Dopa equivalent milligrams
- Comparison between nQ and the CISI-PD, PDQ-39 and NMSS scales [ Time Frame: 4,8,16,24-weeks ]Correlation (Spearman Rho) between the indices and the CISI-PD, PDQ-39 and NMSS scales.
- Stability of the nQ index in a less controlled environment ("home-setting"). [ Time Frame: Week 1 ]Bland-Altman analyses to evaluate the stability of the indices in different days where the medication was not changed and therefore a change should not be expected
