Essays on Hippocampal

Physical Activity for Alzheimer's Patients

The topic I have chosen is mostly based on my personal experience working in about six Emergency Department. My PICOT choice is personal to me because I see this problem frequently and I feel it’s unethical and needs to be adequately addressed. The population I am referring to is our senior citizens with Alzheimer’s disease. The intervention that I would like to see introduced is the use of improved therapeutic physical activity to treat their anxiety while in a hospital setting. The comparison would be to see how using physical therapy opposed to only medications can reduce ...

In the article “Effect of Exercise Training on Hippocampal Volume in Humans: A Pilot Study,” Beth Parker, Paul Thompson, Kathryn Jordan, Adam Grimaldi, Michal Assaf, et al. (2011) perform a preliminary study studying “the direct effect of supervised exercise training on MRI estimates of hippocampal volume in healthy humans” (p. 585). The hypothesis utilized by the researchers was that “exercise training increases hippocampal volume” (Parker et al. 2011, p. 588). For this study, thirteen men and women – all healthy, nonsmoking adults between 23-45 years of age with no exercise or chronic diseases – were utilized, which is a comparatively small ...

Embodied cognition incorporates that the human cognition is comprised and shaped by various aspects of the body, which eventually indicates that it exceeds from the dependency on brain. In this manner, cognition is observed to be dependent on the experiences that an individual receives from numerous sensorimotor capabilities of the body. These capabilities are considered to be highly integrated in accordance with the psychological, biological and cultural setting of an individual (Wilson & Foglia 2011). Embodied cognition also accounts for the feedback mechanism that takes place between an individual and the world and hence, the prevalence of action ...

Sleep, Memory, And Aging. The Link between Slow-Wave Sleep and Episodic Memory Changes from Younger to Older Adults. Sleep, Memory, And Aging. The Link between Slow-Wave Sleep and Episodic Memory Changes from Younger to Older Adults.

Introduction

An interesting modern healthcare development has been found in the discovery of slow wave sleep in the reactivation of episodic memories. It, however, decreases its effect while the age of the patient is increasing. Also, little research has been found on the use of slow wave sleep on the elderly with the majority of the volunteers for the test being of the younger ...

Recreational adolescent use of marijuana can result in adult cognitive problems including learning, thinking, and memory problems (Crean, Crane, & Mason, 2011). Marijuana, also known as cannabis, is known to humanity for thousands of years. It is obtained from the hemp plant, known as Cannabis sativa. Marijuana is one of the most popular, easily obtained drugs, and controversial drugs. It contains psychoactive chemicals such as delta-9-tetrahydrocannabinol, which was obtained in the mid-1960s. This is the key chemical behind the development of controversies in this and the last century. Certain others aspects of the endocannabinoid system including cannabinoid ...

In Daniel Levitin’s TED Talk, “How to Stay Calm When You Know You’ll Be Stressed”, Levitin, a neuroscientist, gives sound recommendations on how to override the brain’s fight-or-flight mechanism, which regulates the brain’s secretion of cortisol and adrenaline into the bloodstream during times of distress. First, during his story, he recounts an episode where he lost the keys to his house, and rather than freeze outside, he lofted a brick through the window. As a neuroscientist, he realized (later) that the hippocampal structure of his brain remembers things spatially, due to our hunter/gatherer origins. Thus, ...

Health-Related News Story

The accuracy and credibility of health-related news article is of significance as incorrect information can be misleading to patients and the general population. This paper will trace the origin of a health-related story and evaluate its accuracy and representativeness of its contents in relation its source article. The health-related story selected for the article was published in the New York Times on 17th February 2016. It is authored by Reynolds and is entitled “Which type of exercise is the best for the brain”. The article reports the findings of a study by Nokia et al. (2016) entitled “Physical exercise ...

The present essay describes the seminar on 5HT receptors and Hippocampus Stem cells. Mood and anxiety both are disorders related to cognitive behavior, and they have the similar genetic origin as well as treatment strategies. The research has exhibited that similar neural serotonin receptors are involved in pathological condition of mood and anxiety. Among all cognitive disorders, 10% are related to mood while 15-20% are associated with anxiety, showing mutual comorbidity of 30-60%. The lecturer talked about the Stem cells and neurogenesis in brain citing a quote “In the adult centers, the nerve paths are something fixed, ended, and ...

Introduction

Narratives and storytelling have been espoused with the development of our sense of self and personal identity. Illness on the other hand has been shown to potentially impact on the development of the self and identity. Medical sociologists create a distinction between disease and illness describing disease in terms of biology that is the underlying pathology and illness as the social response to diseases especially in light of the fact that we exist within a social context. Illnesses therefore have no biological basis and are termed social constructs of diseases. In essence therefore, the way a particular illness is perceived varies from ...
