Cerebral vascular accident or a stroke is the destruction of brain substance, resulting from thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. In addition, it is an area of the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke. Each year alone about 150,000 people in America die from a stroke or are seriously disabled. Stroke is
trauma, and has the advantage of being readily accessible with relatively quick acquisition times (1, 23, 25). It is highly sensitive and specific for the detection of acute cranial injury, intracranial haemorrhage, and secondary changes such as cerebral oedema and infarction (1, 23, 25). Fractures and soft tissue swelling can also be diagnosed on CT using appropriate window settings (26). Further evaluation with MRI may be helpful in the setting of an abnormal CT examination (22). Chest CT is
Epidural hematomas are a severe complication of head injuries and are considered to be a medical emergency. Although they may not be seen as often as subdural hematomas, they are much more serious and require emergency surgery. If epidural hematomas are not picked up quickly, they can result in severe neurologic deficits and even worse, death. A major concern in a patient with an epidural hematoma is failure to rescue by healthcare professionals. Failure to rescue is when healthcare professionals
Lateralization of Function in Cerebral Hemispheres One of the major goals of neuroscience is to be able to understand the relationships between the structures of the nervous system and a persons outward behavior. Often times it is difficult or unethical to directly study the nervous system during a behavior and indirect methods must be used instead. One example of such an indirect method is using a subjects preferred hand to predict which of the two Cerebral Hemispheres is dominant. The are
not being processed for some reason. There are two types of achromatopsia, one is congenital and the other can be caused by brain damage, called cerebral achromatopsia (3). There are also varying degrees of achromatopsia, with some sufferers being able to distinguish some color and others absolutely none. I will focus on the congenital version since cerebral achromatopsia varies in its symptoms and cause quite a bit, as well as being much more rare and so fewer cases have been studied. Congenital color

IONS- that might upset the delicate electrochemical gradients of the cerebral fluid.

by a defect, a disease, or an injury. A cerebral aneurysm is an abnormal focal dilation of an artery located in the brain that results from a weakening of the inner muscular layer called the intima of a blood vessel wall (Brisman, 2014). The vessel develops a blister-like dilation that becomes thin and may rupture without warning. The rupture causes bleeding into the space around the brain which produces a subarachnoid hemorrhage (SAH). This kind of hemorrhage can lead to a stroke, coma , and/or death
person which includes paralysis, comatose, and even death. What is brain hemorrhage? One of the common problems that our brain can develop is known as a brain hemorrhage. Brain hemorrhage or cerebral hemorrhage refers to the condition wherein there is bleeding in the brain. This bleeding can occur anywhere inside the skull which includes the area within the brain,
It is the largest brain structure in humans and makes up two-thirds of the total mass of the brain (“Cerebrum Anatomy”, 2015). Its surface, a covering made up of grey matter usually 2-4mm thick, is called the cerebral cortex and is mainly made up of the cell bodies of neurons. The cerebral cortex is responsible for integrating sensory impulses, directing motor activity, and controlling higher intellectual functions. It is also responsible for the state of consciousness, which still remains a mystery
that are out there, to be able to understand what it was exactly, that I was reading. But with a little study and research I found that this is a precise science that is still largely full of mysteries. The study of hemispheric asymmetry with in the cerebral cortex had long been a fascination with the human race. The ancient Aztec cultures used to perform a type of brain surgery on humans. This is evident from the human remains that we find with incisions and piece's missing of the skull. Whether or
most affected. Changes occur in the cerebral cortex (which is how the frontal lobe is affected.) Pick's disease affects the temporal lobes of the brain in 25%, frontal lobes in 25% and both frontal and temporal lobes in 50% of cases (1). Damage to the frontal lobes leads to alterations in personality and behavior, changes in the way a person feels and expresses emotion, and loss of judgment. On a microscopic level, there is severe neuron damage in the cerebral cortex. The brain cells in these areas
and more important and imperative due to the fact that the overall population seems to becoming more and more emotionally fragile and more subject to several cerebral ills such as depression, anxiety, hysteria, and clinical insanity. A good question to ask is whether or not the overall population seems to be suffering more mental and cerebral ills, or that it is merely a result of more cases being reported and more statistics calculated. But if it is true that the number of people suffering from
In definition, the words Cerebral Palsy are used to describe a medical condition that affects control of the muscles. Cerebral means anything in the head, and palsy refers to anything wrong with control of the muscles or joints in the body. If someone has cerebral palsy, it means that because of an injury to their brain (that's the cerebral part), they are not able to use some of the muscles in their body in the normal way (that's the palsy part). Children who have cerebral palsy, or CP, may not be
There are things in life which none of us can control, in my life there have been many such things. In trying to write this essay I have a difficult time trying to decide what I am going to write about. I have many ideas running through my head,and I am trying to decide what makes me who I am, what makes me special. Soren Kierkegaard said, "Life can only be understood backwards, but must be lived forwards." I have a difficult time understanding my life even as I look back, I am unsure of why
the things I am dealing with when trying to decide whether or not to put my son in a group home. My son is nine years old and suffers from Autism, Cerebral Palsy, and mental retardation.He was born prematurely and critically ill. Though odds were very much against him, he made it. A year later, after his first MRI, we first heard the words Cerebral Palsy. By the age of two I knew he was Autistic but we could not get a diagnosis until he was seven. He was put on medication to help his self-abusive
patterns dependent on the simultaneously activity of neurons. This essay deals primarily with neurons from the optical sensory system. The outer ridge of the brain, known as the cerebral cortex begins the analysis of sensory messages. (1) Nevertheless, visual perception is possibly more widespread than one area of the cerebral cortex and like ly over various subcortical structures and number of different systems as well. (2) One of the many ways for the "perception process" to begin, is vision. Vision
Epilepsy Epilepsy is a very common neurological disorder. Some reports estimate that five in one-thousand people suffer from this problem. Throughout history, people with epilepsy have been shunned or considered inferior. Even today, ignorance leads many people to treat the epileptic as "abnormal" or "retarded". Although the etiology of epilepsy is still not fully understood, it is quite treatable due to advances in modern medicine. Epilepsy is characterized by uncontrolled excessive activity
Introduction A cerebral arteriovenous malformation (AVM) is an irregular connection of arteries and veins within the brain that has no definite cause; many do not experience symptoms (Mayo Clinic Staff, 2011). However, some patients experience headaches and seizures (Starke et al., 2009). The main risk of an AVM is hemorrhage, and patients with AVMs will always have some risk of hemorrhage (Ogilvy et al., 2001); According to Ogilvy et al (2001), more than 50% of AVMs lead to cerebral hemorrhage. The severity
Humans are unique species because we have the ability to adapt to any environments. This ability sets us apart from other animals because we have invented many tools that enable us to alter our way of living to any environment: clothing, medicine, agriculture, food and so on. Whether humans chose to engage in the environment is up to them. Even though we have the capability of adapting, how do humans assess the effectiveness of an environment for their creative output? An enriched environment excites
Reaction Time & Coordination Lab Purpose: to study the ability of the brain to handle different kinds of activities. Background: The primary motor area is controls individual muscles. Most of the neurons in this primary motor area control body areas having the finest motor control including the hands. The cerebellum at the back of the neck coordinates muscle motion, in this case- hand- eye coordination. The cerebellum provides the precise timing for skeletal muscle activity and controls our balance
