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.
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.
Interventions
BEHAVIORALSMR 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.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Neurofeedback Technology Acceptation Questionnaire | 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. |
