Effects of a Common Cold Treatment on Cognitive Function

The RVIP assessed the performance of visual attention mechanisms in remaining vigilant to periodically occurring events. Participants monitored a series of single numbers (0-9) appearing in the centre of the screen. During the RVIP task, participants responded to consecutive sequences of three odd or three even numbers by pressing the corresponding response button as quickly and accurately as possible. The test lasted approximately 9 minutes and mean number of valid responses to stimulus was calculated.

Auditory and visual attention of participants was evaluated using a validated Sustained Attention task. For the sustained visual attention task, participants were required to respond to the letter 's' every time it appears in a continuous stream of letters presented on a screen. For the sustained auditory attention task, participants responded to the number '8' every time it appears in a continuous stream of numbers presented through headphones. Total test duration was approximately 6 minutes. Mean values of valid responses to visual and auditory tests were calculated.

For the DAT Cognitive test, auditory and visual stimuli were simultaneously presented and participants were asked to respond to occurrences of 's' (visual) or '8' (auditory). Total test duration was approximately 6 minutes. Mean values of valid responses to visual and auditory tests were calculated.

Mood patterns was evaluated using the Mood, Alertness and Physical Sensation Scales (MAPSS) which comprised of 23 questions describing moods and physical sensations, on a 9-point scale anchored at the left hand end with 'not at all' and the right hand end with 'extremely'. For each question, '9' represented the 'best' score and '1' represented the 'worst' score. Mean score was calculated by summing the responses and dividing by the number of questions answered. MAPSS Questionnaire was further divided into three main clusters: Alertness; Anxiety and Headache as per the questions.
