Cerebellar lesions

Mixed common threshold for grey matter and white matter overestimate the perfusion lesion in white matter, but underestimate the tissue in white matter [71, 89, 90](summary of the threshold for grey matter and white matter separately from previous studies in figure 7). The variation of absolute perfusion values is highly individual. Furthermore

The Biological Concepts and Mechanisms of Strokes A stroke is a deficit or blockage of oxygenated blood to a portion of the brain. According to the American Heart Association,”stroke is classically characterized as a neurological deficit attributed to an acute focal injury of the central nervous system by a vascular cause, including cerebral infarction, intracerebral hemorrhage, and subarachnoid hemorrhage, and is a major cause of disability and death worldwide (Sacco, 2013, Introduction, para

Paul Ojugo The human body is complex, and all humans are similar to one another in many ways. As humans we share a lot of characteristics in common with one another, such as having hands, feet, eyes, nose, gender, ethnic backgrounds and etc. There has to be some characteristic or organ we have that differentiate all of us, and all these features we have in common, and that is our brain. The brain is one of the largest and most complex organs in the human body. It is made up more than 100 billion

Schizophrenia: A Possible Etiology? As for me, you must know I shouldn’t precisely have chosen madness if there had been any choice. What consoles me is that I am beginning to consider madness as an illness like any other, and that I accept it as such. -in a letter to his brother Theo According to the National Institute of Mental Health, nearly 20% of the US population may suffer from a diagnosable mental illness in any given six month period (1991). Obviously the issue of mental

I chose this article because I am very interested in the field and study of the brain also known as neurology. I wanted to study a predominant disease that ails society which is malaria. I know that malaria affects thousands in many unfortunate countries and has afflicted many children and adults. Malaria is a disease carried by vectors, usually mosquitos, that are mostly predominate in Africa and has many different symptoms ranging from the mild (coughing or chills) to serious (cerebral malaria

The debilitating disease affecting 20-45 year olds around the world: Multiple Sclerosis (MS). This unpredictable disease makes it somewhat challenging for doctors to diagnose it, as it can mock other diseases. Symptoms are variable and come in different degrees of severity. No two people have the exact same symptoms. There are four main categories of MS, with different treatment options. If controlled, MS will only have a few limitations and is, for the most part, ease to adapt to. Multiple sclerosis

Reason for Presentation: “I have severe, deep pain in my lower back, right leg and both arm that hasn’t resolved in 2 days.” History of Presenting Illness: Marilyn Monroe is a 22-year-old female with a known history of Sickle Cell Disease (Hemoglobin SS). She presented to the Emergency Department with excruciating “deep” pain, which she rates 9/10 to her lower back, right thigh, and both arms for two days. It has not resolved with oxycodone 10 mg as needed that she has at home. She reports she has

1. Review the anatomy of the brain. Which portion is responsible for keeping you awake, controlling thought, speech, emotions and behavior, maintaining balance and posture? Emotions and behavior are controlled by the hypothalamus (p.455) The cerebellum is responsible for maintaining balance and posture (p.455) The reticular formation is essential for maintaining wakefulness and in conjunction with the cerebral cortex is referred to as the reticular activating system (p.450) The Broca speech

signals of energy balance into adaptive behavioral outcomes thought to be involved in further executive functions that inhibit food intake. It also was found obesity to be related to atrophy and dysfunction of the hippocampus and that hippocampal lesions may lead to increased appetite and weight

MULTIPLE SCLEROSIS INTRODUCTION The word sclerosis comes from the Greek ‘skleros’ meaning hard. In multiple sclerosis, hard areas called ‘plaques’ (also known as lesions or scars) develop around the damaged nerves. ‘Multiple’ refers to the many different areas of the central nervous system that may have damaged myelin.1 Multiple sclerosis (MS) is a neurological disease that involves the central nervous system (CNS), the nerves that comprise the brain and spinal cord. It has two major features2:
