A consent management system may receive a request to modify consent data associated with a patient. The system may obtain patient capacity information associated with the patient and may determine whether to allow the patient to modify the consent data based on the obtained patient capacity information. The patient capacity information may indicate patient cognitive capacity, patient emotional capacity and/or the like. A response to the consent modification request may be generated based on the determining. For example, based on a determination that the obtained patient capacity information indicates that patient lacks the capacity to modify the consent data, the response may indicate a rejection of the request (e.g., may indicate that the consent data may not be modified). Based on a determination that the obtained patient capacity information indicates that patient possesses the capacity to modify the consent data, the response may indicate an approval of the request.
