If the resident is randomized to the control group, the resident will not receive a reborn®doll. The investigating team will observe the resident's behavior as if he or she were receiving a doll.

The investigating team will give the Reborn®doll to the resident, during a 45-minute to 1-hour workshop, twice a week for 3 weeks. The OTs, wrapped in a blanket, are presented to the residents by a member of the investigative team trained in reborning , in the resident's room. If the resident is not in his/her room, he/she will be taken back to receive his/her doll. In the case of double rooms, it will be necessary to assess whether or not to leave the room-mate in the room, in order to limit the loss of reference points for the resident concerned by the study. The caregiver lets the resident appropriate and recognize the OT, so that he or she can find meaning in it and awaken his or her sensory memory.In total, the patient will be exposed to OT 6 times.

The number of episodes of agitation will be collected weekly by the nursing assistant or nurse in charge of monitoring, by compiling the events reported on a resident monitoring document with the time of recording.

The characterization of these episodes should correspond to one of the items on the Cohen Mansfield scale. Two consecutive episodes cannot be counted if they are less than one hour apart (and will therefore be counted as a single event). Follow-up should be strictly identical, whether the resident belongs to the intervention group or the control group.
