Abstract The paper presents a software platform to design serious games for the rehabilitation of severe memory loss by means of Virtual Reality (VR). In particular, the focus is on retrograde amnesia, a condition affecting patient's quality of life usually after brain stroke. At present, the standard rehabilitation process includes showing pictures of patient's familiar environments to help recovering the memory. The proposed rehabilitation platform aims at developing patient-specific serious games for memory loss starting from the 3D scanning acquisition of familiar environments. The Occipital Structure Sensor and the Skanect application have been used for the virtualization of the real objects and the environment. A modular procedure has been designed to interface the virtual objects of each acquired environment with the modules of the game-logic developed with Unity. In addition, the developed solution makes available a set of software modules for the patient's monitoring and the data management to automatically generate medical reports, which can be easily connected to each new patient-specific serious game. A specific test has been performed to assess the main features of the VR platform and its usability. A positive feedback has been given by the involved medical personnel, who highlighted the importance of objective data to improve the ecological validity of the cognitive rehabilitation for retrograde amnesia.

Abstract The paper presents a method to develop Virtual Reality (VR) platforms based on serious games for the rehabilitation of severe memory loss. In particular, it is related to retrograde amnesia, a condition affecting patient’s quality of life usually caused by brain stroke. Nowadays, the standard rehabilitation process consists in showing pictures of patient’s familiar environments in order to recover the memory. Past research works have investigated the use of 3D scanners for the virtualization of real environment and virtual reality for the generation of more immersive interaction to design serious games for neurocognitive rehabilitation. Reached results highlighted a time-consuming development process to interface each new environment with the game logic specifically developed for the serious games. Furthermore, a complete VR platform must also consider the medical monitoring and the data management oriented to a more objective medical assessment. The proposed method allows the design of VR platforms based on patient-specific serious games for memory loss starting from the 3D scanning acquisition of familiar environments. The 3D acquisition is performed using the Occipital Structure Sensor and the Skanect application. A modular procedure has been designed to interface the virtual objects of each acquired environment with the modules of the game-logic developed with Unity. The immersive Virtual Reality is based on the use of the HTC Vive Pro head mounted display. Furthermore, the method permits to associate the patient-specific serious game to a set of software modules for the medical monitoring and the data management for the generation of reports useful for the evaluation. The solution has been evaluated by measuring the time needed to develop a whole VR platform for two different familiar environments. Less than 5 hours are required to complete the design process.

Background and Aim: Comorbid conditions and unhealthy lifestyles are risk factors for auditory dysfunction, including age-related hearing loss. With a focus on adults, this paper describes a new approach to hearing health care that aims to prevent or mitigate hearing loss and related disorders, like tinnitus. Accurate diagnosis and effective management of hearing loss is best achieved with a patient-specific test battery that includes sensitive measures of peripheral and central auditory function. Background and Aim: Comorbid conditions and unhealthy lifestyles are risk factors for auditory dysfunction, including age-related hearing loss. With a focus on adults, this paper describes a new approach to hearing health care that aims to prevent or mitigate hearing loss and related disorders, like tinnitus. Accurate diagnosis and effective management of hearing loss is best achieved with a patient-specific test battery that includes sensitive measures of peripheral and central auditory function. Conclusion: The traditional model for hearing health care service delivery relies on a rather outdated and simplistic protocol for evaluating and describing hearing loss, and a technologyfocused approach for management. This paper offers an evidence-based rationale for expanding the test battery for diagnosing hearing loss, and a multidisciplinary intervention approach.   Keywords: Comorbid conditions; smoking; diet; value-added tests

Abstract Background The Occupational Therapy (OT) service in the integrated care HUB team was established in January 2018. Prior to this, there was an established memory clinic, however with inconsistent access to OT. The streamlining and structuring of memory clinics further highlighted the need for post-diagnostic support for example individual sessions focusing on memory education and practical strategies to enable independence in daily activities. The integration of OT enabled person-centred strategies to be provided to individuals experiencing memory loss. Methods A retrospective analysis was completed comparing the number of OT memory patient contacts between January to June 2018 and November 2018 to April 2019 also reflecting the memory care pathway developed during this period. OT assessed all new patients experiencing memory difficulties that impacted on functional activities to initiate referral process. In April 2018, the Memory Technology Resource Room (MTRR) opened and the OT HUB using to facilitate patient contacts. The design/implementation of cognitive rehabilitation groups in May 2018 added another step to pathway. Dementia cafés were established in public cafés in the city and county area, sponsored by local care provider, also supported by HUB team. Feedback was gathered from surveys given to individuals, carers and HUB team in the Café and MTRR. Results From January to June 2018 there were 50 memory streamed patient contacts completed by the OT. From November 2018 to April 2019, 206 patient contacts were completed. These include both individual and group cognition focused sessions. Positive qualitative feedback was retrieved from attendees to MTRR and Café all indicating at least one positive outcome from post-diagnostic supports and services. Conclusion A multi-domain cognitive OT service when initiated by an integrated care HUB proves to be an effective and acceptable memory care pathway. The development of this holistic pathway enabled the person to be seen in the right place, at the right stage of their journey with memory difficulties.

ABSTRACT:Retrograde amnesia was assessed in demented and non-demented Parkinson’s patients using a test of remote memory spanning the years from 1920-1979. Results indicated that the demented patients 1) scored significantly below normal controls and 2) had equal impairment for all time periods. This pattern was like that seen in other dementing illnesses (i.e., Huntington’s and Alzheimer’s diseases), but different from that in amnesic disorders, such as Korsakoff s syndrome. The data, therefore, suggest qualitative differences in pattern of remote memory loss between the dementias and amnesic syndromes.
