Abstract: A tool is described for supporting an individual suffering from a mental condition or disorder characterized by auditory hallucination. The tool assists in training the individual to distinguish between an acute auditory hallucinatory episode and ambient sounds. The tool monitors for a deliberate overt activation action by a user, where the activation action represents an indication that the user is hearing sounds. The activation action causes the tool to receive a perception indication from the user. The perception indication is either an indication that the user perceives that they are hearing actual sounds, or an indication that the user perceives that they are experiencing an auditory hallucination. A microphone monitors ambient sounds, which are tested against a threshold to determine and whether the perception indication was correct. A report on the correctness of the perception indications may be provided to the user.

Abstract: A tool is described for objectively identifying and providing assessment of acute psychotic episodes, such as auditory hallucinations, symptomatic of a mental condition or disorder. The tool can include an audio interface on a microphone-equipped networked mobile wireless telecommunication computing device which a patient can use to determine whether the perceived sounds are real or hallucinatory. If the microphone fails to detect ambient sounds indicating that the sounds are real, the application can provide a remote alert signal so that appropriate parties (e.g. the patient's treatment team or emergency medical personnel) can take action.
