Data on prevention of perioperative neurocognitive disorders (pNCDs) are limited. The purpose of this monocentric parallel - grouped observational registry is to collect study data from studies with pNCDs as primary or secondary endpoint to estimate prevalence and incidence of pNCDs.

Cohort
Prospective
Not listed
Neurocognitive Disorder (NCD)
Mild / major neurocognitive disorder 3 (mild / major NCD 'Postoperative cognitive dysfunction (POCD)') and 12 months (mild / major NCD) postoperatively.
Postoperative cognitive dysfunction (POCD)
Postoperative cognitive dysfunction (POCD) is defined as relevant change in postoperative cognitive performance compared to baseline (preoperative) cognitive performance.
Suspected neurocognitive disorder due to MiniCog
The MiniCog is used for cognitive screening. A cut-off value of \<3 points is interpreted possible mild / major NCD. The Mini-Cog consists of a sub-test for word memory skills and a clock drawing test.
Suspected dementia from MOCA
The Montreal Cognitive Assessment (MOCA) with cut-offs according to normative age-adjusted values is used as dementia screening. The MOCA consists of 13 items, which are rated on a scale from 0 to 30 points.
Neurocognitive Disorder (NCD)
Mild / major neurocognitive disorder (mild / major NCD) 60months postoperatively.
Suspected postoperative neurocognitive disorder (mild / major NCD 'POCD')
The non-computerized neuropsychological trail making test is used as an indicator screening test for relevant cognitive changes after the operation. The cut-off is an increase in TMT-B test performance of\> 55 seconds three and / or 12 months after the operation compared to the baseline value.
