Embodied cognition in neurodegenerative disorders: What do we know so far? A narrative review focusing on the mirror neuron system and clinical applications.

Embodied cognition is a theoretical perspective that considers every form of human knowledge and cognition "embodied", as they pass through bodily experience. The aim of this narrative review is to investigate the importance of mirror neurons system in EC, as well as the EC role in neurodegenerative diseases. This narrative review shows deep connections between body and mind: body states influence mental functions such as perception and reasoning, while mental states cause changes in the body, especially in neurodegenerative disorders. Indeed, abnormalities in EC were found in dementia, Parkinson's Disease and Amyotrophic Lateral sclerosis, also in the absence of other cognitive deficits, negatively affecting patients' outcomes. Exploiting EC mechanisms for rehabilitation purposes, also using innovation technologies, could be a promising therapeutic way to increase motor and cognitive outcomes in patients affected by different neurological disorders.

Effects of robotic neurorehabilitation through lokomat plus virtual reality on cognitive function in patients with traumatic brain injury: A retrospective case-control study.

Background: Traumatic brain injury (TBI) is a clinical condition characterized by damage due to a mechanical physical event, which has a devastating impact on both the patient and his/her family. The purpose of this study is to evaluate the effects of robotic neurorehabilitation using Lokomat with virtual reality (VR) on attention processes and executive functions in patients with TBI.Materials and Methods: This is a retrospective case-control study. Fifty-six TBI patients have been included in the analysis, using an electronic recovery data system. The enrolled patients were divided into two groups: the experimental group (LPG) underwent rehabilitation training with Lokomat Pro, equipped with a VR screen, whereas the control group (LNG) performed rehabilitation training using Lokomat Nanos, without VR. The two groups matched for age, sex, education, brain lesions, interval from TBI. The rehabilitation protocol consisted of a total of 40 training sessions.Results: LPG and LNG had a significant improvement in mood and in the perception of physical well-being. However, only the LPG had a significant improvement in global cognitive, executive and attention functions. Furthermore, LPG presented a significant enhancement of the quality of life, with regard to the perception of the mental and physical state.Conclusion: Our study supports the idea that Lokomat is a useful tool in the rehabilitation of patients with TBI; in particular, the integration of the VR device can implement the cognitive and behavioral functions of TBI patients, enhancing also their physical and mental well-being.

Changes in sexual functioning following traumatic brain injury: An overview on a neglected issue.

Traumatic brain injury (TBI) is any damage to the skull and/or the brain and its frameworks due to an external force. Following TBI, patients may report cognitive, physiological and psychosocial changes with a devastating impact on important aspects of the patient's life, such as sexual functioning. Although sexual dysfunction (SD) occurs at a significantly greater frequency in individuals with TBI, it is not commonly assessed in the clinical setting and little information is available on this crucial aspect of patients' quality of life. As the number of people with TBI is on the rise, there is a need for better management of TBI problems, including SD, by providing information to patients and their caregivers to achieve sexual health, with a consequent increase in their quality of life. Discussing and treating sexual problems in TBI patients enters the framework of a holistic approach. The purpose of this narrative review is provide clinicians with information concerning changes in sexual functioning and relationships in individuals with TBI, for a better management of patient's functional outcomes and quality of life.
