The Primary Efficacy Objective of This Study is to Assess the Efficacy of SYN120 on Cognition as Determined by the Cognitive Drug Research Computerized Cognition Battery (CDR) Continuity of Attention in Patients With Parkinson's Disease.
Tijdsspanne: up to Week 16
|
To access the effect of SYN-120 for Continuity of Attention, a measure which reflects the ability to sustain attention and avoid error The Cognitive Drug Research Computerized Cognition Battery is a computerized neuropsychological test battery to assess cognitive tasks based on measures of Vigilance (1 - 180 seconds) and Choice Reaction Time (1 - 120 seconds). The stimuli are presented on a computer screen and the subjects respond by pressing either a "Yes" or "No" on a response box. It is a time measured test. The ability to keep mind on a single task over time. COA is calculated as (VIGACC*0.45) + (CRTACC*0.5) - where VIGACC is digit vigilance accuracy, CRTACC is choice reaction time accuracy. Higher COA scores represent greater sustained attention and avoidance of errors. |

To Assess the Effects of SYN120 on Cognitive Drug Research Computerized Cognition Battery (CDR) Quality of Episodic Memory (QEM)
Tijdsspanne: up to Week 16
|
To access the effects of SYN120 for Quality of Episodic Memory. QEM measures the ability to store, hold, and retrieve information of an episodic nature. The stimuli are presented on a computer screen and the subjects respond by pressing either a "Yes" or "No" on a response box. It is a time measured test. Quality of Episodic Memory is calculated as (DRECOACC + DRECNACC - 100) + (DPICOACC + DPICNACC - 100) +((IRCL - IRCLERR)*100 / 15) + ((DRCL - DRCLERR)*100 / 15), where DRECOACC is Word Recognition original stimuli accuracy (1 - 120 seconds), DRECNACC is word recognition new stimuli accuracy, DPICOACC is Picture Recognition original stimuli accuracy (1 - 120.5 seconds), DPICNACC is picture recognition new stimuli accuracy, IRCL is Immediate Word Recall (1 - 120.5 seconds), IRCLERR is immediate word recall errors, DRCL is Delayed Word Recall (1 - 120.5 seconds), and DRCLERR is delayed word recall errors. Higher QEM scores greater ability to retain memory. |
