Infectious Etiology

When the frontal lobe of the brain is affected important behavioral changes may occur mainly at the level of executive functioning, i.e., planning, decision-making, judgment and self-perception. However, the behavioral changes may be of different nature with marked indifference and apathy. We report a clinical case of an 81-year-old patient with sudden onset of behavioral changes that were initially interpreted as an acute confusional episode of infectious etiology, but actually they were due to an ischemic lesion in the frontal lobe.

Occlusive Arteriopathy

✓ Four cases with the association of occlusive arteriopathy and brain tumor are presented. A clinical analysis of these cases and cases reported in the literature revealed that occlusive arteriopathy at the base of the brain was often associated with a slowly growing basal tumor in children. Possible causes of occlusive arteriopathy in these cases were compression of the circle of Willis by a slowly growing basal tumor, secondary arterial occlusive changes by radiation therapy for a basal tumor, or vasculopathy associated with neurocutaneous syndrome. Symptoms of sudden onset or episodic nature suggest the presence of occlusive arteriopathy rather than the mass effect of a tumor. Cerebral angiography is mandatory whenever computerized tomography (CT), performed to rule out recurrence of a basal tumor, shows an ischemic lesion with low-density areas without any evidence of mass effect of the tumor. Cerebral angiography is also necessary when a basal tumor is suspected in children, particularly in cases associated with neurocutaneous syndrome and a basal tumor. Care should be taken not to scarify the abnormal vascular network at the base of the brain at the time of operation, because it is considered to be functioning as collateral circulation. The potential hazards of radiotherapy to radiation-induced occlusive changes of the circle of Willis must be considered in treating a benign basal brain tumor in children. Even in adults, repeated large doses of irradiation could cause occlusive arteriopathy.

Computational Modeling and Visual Algorithm allows for the creation of a Visual cognitive diagram that explains areas of the brain they represent to spatial abstraction and mental calculation. For example, the temporal lobe is associated with memory and the occipital lobe is associated with vision. The cerebral cortex is where decision- making, thinking, and information process takes place. Moreover, in the frontal lobe is where decision making, takes place and the parietal lobe influences areas of the brain that correlate to spatial calculation and mind mapping. This is created in a diagram that expresses each area like a visual algorithm. A visual algorithm is created in different scales that are associated with numerical numbers and the frontal lobe sub division [1]. The creation of this visual algorithm explains the nodes and the functioning of the levels of the brain and neuroscience. The connection and the functions of the brain control our learning, motor content, and mayor nerve connections. The visual algorithm present an abstract and perception pattern to look at thinks. It connects with the nodes that affect our cognitive human perception factor. The lobes of the brain resemble this area and provide an in-depth understanding to what a cognitive hierarchy is. The lobes are important factor to the perception of thinking, learning, and memory. Each one with a significant function to learning and neuroscience [2]

Purpose The purpose of this clinical focus article is to provide speech-language pathologists with a brief update of the evidence that provides possible explanations for our experiences while coaching college students with traumatic brain injury (TBI). Method The narrative text provides readers with lessons we learned as speech-language pathologists functioning as cognitive coaches to college students with TBI. This is not meant to be an exhaustive list, but rather to consider the recent scientific evidence that will help our understanding of how best to coach these college students. Conclusion Four lessons are described. Lesson 1 focuses on the value of self-reported responses to surveys, questionnaires, and interviews. Lesson 2 addresses the use of immediate/proximal goals as leverage for students to update their sense of self and how their abilities and disabilities may alter their more distal goals. Lesson 3 reminds us that teamwork is necessary to address the complex issues facing these students, which include their developmental stage, the sudden onset of trauma to the brain, and having to navigate going to college with a TBI. Lesson 4 focuses on the need for college students with TBI to learn how to self-advocate with instructors, family, and peers.

Rule Out

There are several causes for sudden onset unilateral mydriasis, however impending transtentorial uncal herniation needs to be ruled out. This unique case highlights an uncommon adverse response to a common mode of treatment that leads to a diagnostic dilemma. A 3-year-old boy with a ventriculoperitoneal (VP) shunt for an obstructive hydrocephalus presented with an acute respiratory distress. He developed unilateral mydriasis with absent light reflex during treatment with nebulisers. An urgent CT scan of the brain did not show any new intracranial abnormality. A case of pharmacological anisocoria was diagnosed that resolved completely within 24 hours of discontinuation of ipratropium bromide. Although ipratropium-induced anisocoria has been reported in children, but to our knowledge none in a child with VP shunt for hydrocephalus. This emphasises the urgency in evaluating unilateral mydriasis to rule out life-threatening conditions. Clinicians should remember that ipratropium administered through ill-fitting face masks could cause this completely reversible adverse effect.

Abstract Background Women’s empowerment is multidimensional. Women’s education, employment, income, reproductive healthcare decision making, household level decision making and social status are vital for women’s empowerment. Nepal is committed to achieving women empowerment and gender equality, which directly affects the reproductive health issues. This can be achieved by addressing the issues of the poor and marginalized communities. In this context, we aimed to find the association of women’s empowerment with abortion and family planning decision making among marginalized women in Nepal. Methods A cross sectional study was conducted at selected municipalities of Morang district of Nepal from February 2017 to March 2018. A mixed method approach was used, where 316 married marginalized women of reproductive age (15–49 years) and 15 key informant interviews from representative healthcare providers and local leaders were taken. From key informants, data were analysed using the thematic framework method. Findings obtained from two separate analyses were drawn together and meta inferences were made. Results Women’s empowerment was above average, at 50.6%. Current use of modern contraceptives were more among below average empowerment groups (p 0.041, OR 0.593 C.I. 0.36–0.98). We could not find any statistically significant differences among levels of women’s empowerment, including those women with abortion knowledge (p 0.549); family planning knowledge (p 0.495) and women’s decision for future use of modern contraceptives (p 0.977). Most key informants reported that unsafe abortion was practiced. Conclusions Women’s empowerment has no direct role for family planning and abortion decision making at marginalized communities of Morang district of Nepal. However, different governmental and non-governmental organizations influence woman for seeking health care services and family planning in rural community of Nepal irrespective of empowerment status.

The Brain

Once strictly the domain of medical and graduate education, neuroscience has made its way into the undergraduate curriculum with over 230 colleges and universities now offering a bachelor’s degree in neuroscience. The disciplinary focus on the brain teaches students to apply science to the understanding of human behavior, human interactions, sensation, emotions, and decision making. In this article, we encourage new and existing undergraduate neuroscience programs to envision neuroscience as a broad discipline with the potential to develop competencies suitable for a variety of careers that reach well beyond research and medicine. This article describes our philosophy and illustrates a broad-based undergraduate degree in neuroscience implemented at a major state university, Virginia Tech. We highlight the fact that the research-centered Experimental Neuroscience major is least popular of our four distinct majors, which underscores our philosophy that undergraduate neuroscience can cater to a different audience than traditionally thought.

Measures Of Performance

Abstract Motor decision-making processes are required for many standard neuropsychological tasks, including the Trail Making Test (TMT), that aim to assess cognitive functioning in older adults. However, in their standard formats, it is difficult to isolate the relative contributions of sensorimotor and cognitive processes to performance on these neuropsychological tasks. Recently developed clinical tasks use a robotic manipulandum to assess both motor and cognitive aspects of rapid motor decision making in an object hit (OH) and object hit and avoid (OHA) task. We administered the OH and OHA tasks to 77 healthy younger adults and 59 healthy older adults to assess age differences in the motor and cognitive measures of performance. We administered the TMT parts A and B to assess the extent to which OHA performance is associated with executive functioning in particular. The results indicate that after controlling for hand speed, older adults performed worse on the OH and OHA tasks than younger adults, performance declines were far greater in the OHA task, and the global performance measures, which have been associated with cognitive status, were more sensitive to age differences than motor measures of performance. Those global measures of performance were also associated with measures of executive functioning on the TMT task. These findings provide evidence that rapid motor decision making tasks are sensitive to declines in executive control in aging. They also provide a way to isolate cognitive declines from declines in sensorimotor processes that are likely a contributing factor to age differences in neuropsychological test performance.

AbstractWhat is the role of consciousness in volition and decision-making? Are our actions fully determined by brain activity preceding our decisions to act, or can consciousness instead affect the brain activity leading to action? This has been much debated in philosophy, but also in science since the famous experiments by Libet in the 1980s, where the current most common interpretation is that conscious free will is an illusion. It seems that the brain knows, up to several seconds in advance what “you” decide to do. These studies have, however, been criticized, and alternative interpretations of the experiments can be given, some of which are discussed in this paper. In an attempt to elucidate the processes involved in decision-making (DM), as an essential part of volition, we have developed a computational model of relevant brain structures and their neurodynamics. While DM is a complex process, we have particularly focused on the amygdala and orbitofrontal cortex (OFC) for its emotional, and the lateral prefrontal cortex (LPFC) for its cognitive aspects. In this paper, we present a stochastic population model representing the neural information processing of DM. Simulation results seem to confirm the notion that if decisions have to be made fast, emotional processes and aspects dominate, while rational processes are more time consuming and may result in a delayed decision. Finally, some limitations of current science and computational modeling will be discussed, hinting at a future development of science, where consciousness and free will may add to chance and necessity as explanation for what happens in the world.

Planning Decision

Couple communication and joint decision-making are widely recommended in the family planning and reproductive health literature as vital aspects of fertility management. Yet, most studies continue to rely on women’s reports to measure couple concordance. Moreover, the association between communication and decision-making is often assumed and very rarely studied. Arguably, associations between dyadic communication and shared decision-making constitute a missing link in our understanding of how communication affects fertility-related practices. Informed by Carey’s notions of transmission and ritual communication, this study sought to address those gaps with two complementary studies in Nepal: a qualitative study of married men and women and a quantitative study of 737 couples. To assess spousal concordance on matters of family planning-related communication and decision-making in the quantitative study, responses from the couple were compared for each question of interest and matched responses were classified as concordant. Quantitative results found that more than one-third of couples reported spousal communication on all measured family planning-related topics. Nearly, 87% of couples reported joint decision-making on both family planning use and method type. Partner communication was significantly and positively associated with concordant family planning decision-making in both bivariate and multivariate models. Couples communicating about three family planning topics had more than twice the odds of concordant family planning decision-making than did those not reporting such communication. The qualitative findings provided insights into discordant as well as concordant interactions, revealing that decision-making, even when concordant, is not necessarily linear and is often complex.
