- An acquired brain injury often leads to long-lasting mental fatigue, which can have a considerable effect on work and social interactions. Fortunately, the Mindfulness-Based Stress Reduction (MBSR) program has been found to alleviate mental fatigue. The purpose of this feasibility study was to evaluate the success of an interactive MBSR program delivered live online to individuals who have experienced a traumatic brain injury or stroke. We included the following three groups in our study: an Internet group, a face-to-face MBSR group, and an active control group who took weekly walks in natural environments. Thirty-four participants completed the study, and all were suffering from long-lasting mental fatigue after either a traumatic brain injury (16 participants) or a stroke (18 participants). However, seven did not accept to attend an Internet MBSR, and Internet was the only choice for others. We found that, according to the Mental Fatigue Scale (MFS), the program leads to significantly reduced mental fatigue in the Internet group compared with the face-to-face and the control group. Individuals in the MBSR groups also exhibited an improved ability to process two temporally close targets (attentional blink task), while this was not detected in the control group. In conclusion, we believe that it is possible for individuals suffering from mental fatigue after an acquired brain injury to obtain positive results through enrollment in a live, interactive, online MBSR program. This is promising, as the Internet is accessible to many individuals, irrespective of where they live. Further randomized control studies comparing are warranted.

- OBJECTIVESFatigue after an acquired brain injury is common, and is characterized by limited energy reserves to accomplish ordinary daily activities. A typical characteristic of mental fatigue is that the mental exhaustion becomes pronounced during sensory stimulation or when cognitive tasks are performed for extended periods without breaks. There is a drain of mental energy upon mental activity in situations in which there is an invasion of the senses with an overload of impressions, and in noisy and hectic environments. Another typical feature is a disproportionally long recovery time needed to restore the mental energy levels after being mentally exhausted. The mental fatigue is also dependent on the total activity level as well as the nature of the demands of daily activities. For many people, there is an increased risk of doing too much and becoming even more fatigued.METHODSWe have developed an application for Windows Phone for assessment of mental fatigue. The Mental Fatigue Scale is used. The MFS is a multidimensional questionnaire containing 15 questions. The questions included in the MFS are based on symptoms described following longitudinal studies of patients with TBI, brain tumours, infections or inflammations in the nervous system, vascular brain diseases, and other brain disorders. The app also includes information about mental fatigue. RESULTSThis application can help people determine the level of mental fatigue and it can also serve to provide an overall picture of the severity of the condition, and detect changes in mental fatigue over time. The scores will be added up and the results will be presented in the form of a rating scale and a diagram. People can then see their results for one week ago, one month ago or a whole year ago. Today, the most important recommendations are to adapt to the energy available by doing one thing at a time, resting regularly and not overdoing things. However, this is challenging for most people and it may take a long time, even years, to adapt to a sustainable level. It may also be difficult for the person to learn by himself/herself and it can take several years of considerable struggle, frustration, despair and depression, to find the right balance between rest and activity. This app can help people to be aware of mental fatigue. If they connect the results to daily activities, the app may also help them to be more aware about what may alleviate and what may make mental fatigue worse. CONCLUSIONSWith regular assessment of mental fatigue, this app may give feedback and support in order to achieve an enduring balance between activities and rest.The application can be downloaded without cost: http://www.windowsphone.com/en-us/store/app/mental-fatigue/87d4cb88-c9b5-4ac9-9a92-b63a5d8f4d82

- Mindfulness based stress reduction was mediated as e-therapy to a group of patients suffering from mental fatigue. The e-therapy was arranged using standard video conferencing software and web cameras without any studio capacity. During sessions all interaction with participants was handled by psychology professionals. This study shows that it is possible for non-technical specialists to arrange an advanced e-therapy using a low budget setting

Nuclear translocation and calpain-dependent reduction of Bcl-2 after neonatal cerebral hypoxia-ischemia

- Apoptosis-related mechanisms are important in the pathophysiology of hypoxic-ischemic injury in the neonatal brain. Caspases are the major executioners of apoptosis, but there are a number of upstream players that influence the cell death pathways. The Bcl-2 family proteins are important modulators of mitochondrial permeability, working either to promote or prevent apoptosis. In this study we focused on the anti-apoptotic Bcl-2 protein after neonatal cerebral hypoxia-ischemia (HI) in 8-day-old rats. Bcl-2 translocated to nuclei and accumulated there over the first 24h of reperfusion after HI, as judged by immunohistochemistry and immuno-electron microscopy. We also found that the total level of Bcl-2 decreased after HI in vivo and after ionophore challenge in cultured human neuroblastoma (IMR-32) cells in vitro. Furthermore, the Bcl-2 reduction was calpain-dependent, because it could be prevented by the calpain inhibitor CX295 both in vivo and in vitro, suggesting cross-talk between excitotoxic and apoptotic mechanisms.
