Brief Summary:
This is a non-pharmacological study evaluating the feasibility of a neurofeedback training program in elderly with mild cognitive impairment (MCI) according to recruitment, retention, attendance, acceptability data.

Condition or disease Intervention/treatment Phase
Mild Cognitive Impairment, So Stated Behavioral: SMR neurofeedback training to MCI Not Applicable

Detailed Description:
Neurofeedback (NF) can be counted amongst promising techniques to improve cognitive functioning if the principles of application are seriously respected, whilst recognizing the necessary adaptation to the conditions of patients with Mild Cognitive Impairment (MCI). This study examined the feasibility and acceptability of an electroencephalography neurofeedback training protocol in a sample group of older adults with MCI in order to identify the necessary conditions for an improved neurofeedback application. Participants performed an electroencephalography recording, a battery of neuropsychological tests before the neurofeedback training program (T0), following the neurofeedback training program (T2) and 1-month follow-up (T3). A questionnaire about motivation, opinions of technical aspects of NF and feeling of cognitive improvement was administered at T0 and T2.

Arm Intervention/treatment
Experimental: SMR neurofeedback training to MCI

Sensorimotor rhythm neurofeedback protocol consisted of 20 individual sessions, twice a week, during 11 weeks maximum. For each subject MCI, NF was planned and conducted by a neuropsychologist experienced in neurophysiology and neurofeedback. Each session lasted 1h10-15min and was conducted as follows:

  1. Preparation and installation of the electrodes, verification of the impedance, adjustment of the calibration and thresholds (15 minutes).
  2. NF training (tasks and video described below) (45 minutes).
  3. Feedback and debriefing about the session (15 minutes).
Behavioral: SMR neurofeedback training to MCI
SMR neurofeedback training consisted to increase the synaptic strengths and sensitivity within this network. Electroencephalography signals for SMR/theta ratio training was recorded at channel Cz according to the International 10-20 system. Theta rhythm was also recorded and, in this case, SMR was stimulated while theta waves were suppressed. A 32 channels system (EEGDigitrack Biofeedback plus module, Inc Elmiko Medical) was used for SMR/theta neurofeedback training.
Other Name: SMR

Primary Outcome Measures :
  1. Neurofeedback Technology Acceptation Questionnaire [ Time Frame: Assessment was at 2 months immediately after the Neurofeedback intervention ]
    Neurofeedback Technology Acceptation Questionnaire assessed the participants' opinions face to the electroencephalography neurofeedback intervention with 33 questions. The mode of administration was a personal interview with the investigator, the type of questions was closed-ended (for binary variable yes or no). Answers were analyzed with the Multiple Correspondence Analysis to visualize associations and similarities among participants and answers to Questionnaire. An unsupervised hierarchical clustering was performed using the Euclidean distance and Ward's method. Clusters were defined graphically using dendrogram.
