Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention will begin 45-90 days post cardiac event. Consenting participants will be randomly assigned to one of two groups: (1) eight weeks of online neurocognitive training (30 minutes three times per week) or (2) normal clinical management. Participants in the intervention group will receive eight weeks of computerised neurocognitive training applied via the internet platform Happyneuron (Scientific Brain Training, Villeurbanne Cedex, Frankreich). This platform has been chosen after extensive evaluation of the likely training and transfer effects of similar interventions. Twenty-­four training (3 per week over an 8 week period) sessions of 30 minutes each will be performed. In each training session the participants will perform tasks that target functioning across the neuropsychological domains of memory, attention, language, executive functions, and visuo­spatial ability. Participants will attend an individual coaching session before beginning the programme, with training sessions completed at home online. Participant progress will be monitored remotely with 15 minutes of telephone contact on a weekly basis.

Eligibility
Key inclusion criteria
Participants identified in the earlier observational phase of the NOCA project as demonstrating cognitive deficits 30-45 days post arrest will be invited to participate in the randomised controlled trial of online neurocognitive training. Cognitive deficits will be defined as scores <1.5 standard deviations (SD) below the normative mean of the NIH Toolbox cognitive assessment score. Inclusion criteria for the observational phase are:

The inclusion criteria for those participants recruited from the NOCA observational study are:
1. Have experienced out-of-hospital cardiac arrest and received ambulance assistance and transport to hospital.
2. Aged 50 years and over
3. Presence of return of spontaneous circulation following cardiac arrest;
4. Discharged to home by 30 days
Minimum age
50 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
