The effectiveness of working memory training on brain waves changes in early stage of Alzheimer disease 2019-12-11 anticipated 20 Complete https://irct.ir/trial/40219 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: patients will be subdivided into intervention and control groups by flipping a coin (simple individual randomization). N/A Alzeimer. Intervention 1: Intervention group: participants in the training group attend 12 sessions (30 minutes each). the sessions take place 3 days a week for 4 weeks in row (in another words for 1 month). The subject is presented with a sequence of stimuli, and the task consists of indicating when the current stimulus matches the one from n steps earlier in the sequence. The load factor n can be adjusted to make the task more or less difficult.To clarify, the visual n-back test is similar to the classic memory game of "Concentration". However, instead of different items that are in a fixed location on the game board, there is only one item, that appears in different positions on the game board during each turn and subject must remember if the current location of item matches with n step earlier in the sequence. "N-1" means that you have to remember the position of the item, one turn back. "N-2" means that you have to remember the position of the item two turns back, and so on. if the score of subject is more than 75% he or she will go to next n-back level. if the score is between 50%-75% he/she remain the current level. and if the score is less than 50% he/she will go one level back. Intervention 2: Control group: the control group is not under any intervention or treatment. Yes - There is a plan to make this available What will be shared: the data about main consequence (dependent variables) will be shared When: 6 Month after the conclusion get published To whom: limitless Conditions: there is no limit Where to obtain: email: pegah.dehghan14@gmail.com It will be also published as a thesis and will be available in library of Shahid Bahonar University How to obtain: first the responsible of research must approve the request.then data will be sent.
