Brief Summary

Postoperative cognitive dysfunction (POCD) is a disease with restricted cognitive memory function and intellectual skills, which occurs after surgery with and without anesthesia. The POCD strongly depends on patient's age and the surgical operation type. The anesthesia procedure plays a pivotal role as well and regarding the current knowledge it is still uncertain which technique matches the lowest risk. Elevated stress level accompanied with regional anesthesia procedures are accused to cause POCD in elderly patients. The investigators address the question weather regional or general anesthesia leads to a pronounced POCD in dependence of stress incidence.

Outcome Measures

Primary Outcomes (1)

  • Neurocognitive Function

    Using different tests addressing a various quality of neurocognitive function (attention, memory, perceptual and processing speed, alertness and executive function) participants score test appropriate values. Comparing test values separately allows to distinguish between prior - and post - operative status. Moreover it allows to discriminate achieved test results between both groups and calculate statistical differences. Favorable test results lead to a potential better neurocognitive function outcome and enable to assess neurocognitive function in the light of operation consequence.
