# CMDyskineticSymptomResult

A result object that contains data about the likely presence of dyskinetic symptoms during a one-minute interval.

```
class CMDyskineticSymptomResult
```

## Overview

Dyskinesias are uncontrolled, involuntary movements that occur as a side effect of taking Levadopa to control Parkinson’s disease. Dyskinesias can manifest in a single body part, such as the arm, leg, or head, or they can affect the entire body. Particular dyskinesias resemble actions like fidgeting, writhing, wriggling, head bobbing, or body swaying. These symptoms tend to occur during the drug’s peak dosage. Dyskinesias typically occur in patients with advanced Parkinson’s disease, who may require higher dosages of Levadopa.

The following equation is always true: [`percentUnlikely`](/documentation/CoreMotion/CMDyskineticSymptomResult/percentUnlikely) `+` [`percentLikely`](/documentation/CoreMotion/CMDyskineticSymptomResult/percentLikely) `= 1.0`.

> Important:
> Gather and present data on dyskinetic symptom results only to users with choreiform dyskinesias, either self-reported or diagnosed by a clinician.

## Topics

### Reading the Time Interval

[`var startDate: Date`](/documentation/CoreMotion/CMDyskineticSymptomResult/startDate)

The result’s start time and date.

[`var endDate: Date`](/documentation/CoreMotion/CMDyskineticSymptomResult/endDate)

The result’s end time and date.

### Accessing Dyskinetic Symptom Data

[`var percentUnlikely: Float`](/documentation/CoreMotion/CMDyskineticSymptomResult/percentUnlikely)

The percentage of time when dyskinetic symptoms were unlikely.

[`var percentLikely: Float`](/documentation/CoreMotion/CMDyskineticSymptomResult/percentLikely)

The percentage of time when dyskinetic symptoms were likely.
