Brief Summary

Increased activity in the hippocampus (i.e., hyperactivity) during a fMRI memory task was found in patients with Mild Cognitive Impairment due to Alzheimer's disease (MCI). Those with increased hippocampal activity exhibited elevated clinical progression. Reducing hippocampal hyperactivity with pharmacological treatment reduced hyperactivity and improved memory performance. The investigators of this study will test whether real-time fMRI neurofeedback will also downregulate hippocampal activity and thereby improve memory performance.

Outcome Measures

Primary Outcomes (1)

  • Rate of change in hippocampal activity during a memory task

    Measured by fMRI (rate of change in activity from baseline to after the intervention)

    Directly after the intervention

Secondary Outcomes (2)

  • Rate of change in memory performance

    Directly after the intervention

  • Rate of change from in memory performance (behavioural)

    Directly after the intervention

Other Outcomes (2)

  • Strategies for Regulation of hippocampal activity

    Intervention

  • Predictors of neurofeedback success

    Post-Intervention

Study Arms (4)

healthy elderly participants receiving feedback from the hippocampus

ACTIVE COMPARATOR

This group will consist of healthy elderly volunteers, who will receive feedback from their hippocampal activity.

Other: real-time fMRI based neurofeedback from the hippocampus

healthy elderly participants receiving feedback from another area

SHAM COMPARATOR

This group will consist of healthy elderly volunteers, who will receive feedback from another brain area.

Other: real-time fMRI based neurofeedback from another brain area

patients with MCI receiving feedback from the hippocampus

EXPERIMENTAL

This group will consist of patients with mild cognitive impairment, who will receive feedback from their hippocampal activity.

Other: real-time fMRI based neurofeedback from the hippocampus

SHAM COMPARATOR

Interventions

During real-time fMRI neurofeedback, participants are trained to 'control' hippocampal activity. The training is accomplished by continuously measuring brain activity, analysing it in real-time, and then providing feedback about the current (and the targeted) brain activity to the participant.
