Brain scans -These tests can identify strokes, tumors, and other problems that can cause dementia. Scans also identify changes in the 19 brain’s structure and function. The most common scans are computed tomographic (CT) scans and magnetic resonance imaging (MRI). CT scans use X-rays to produce images of the brain and other organs. MRI scans use a computer, magnetic fields, and radio waves to produce detailed images of body structures, including tissues, organs, bones, and nerves. Other types of scans let doctors watch the brain as it functions. Two of these tests are single photon-emission computed tomography, which can be used to measure blood flow to the brain, and positron emission tomography (PET), which uses radioactive isotopes to provide

    Every parent desires to have a child who will be successful in life. In “Brainology” author, Carol Dweck explains that there are consequences for praising children for their work. Dweck also explains that there are different types of mindsets that enable an individual’s development. She claims that there are two types of mindsets that people have. In a growth mindset, people believe that their most basic abilities can be developed through dedication and hard work ( Dweck 1). Furthermore growth mindset individuals love learning and are resilience that is essential for great accomplishment. (Dweck 1). One more theory, Dweck mentioned was fixed mindset. The author states “In a fixed mindset, people believe their basic qualities, like their intelligence

    Other testing procedures that are commonly employed, in order to gain a better visual image of the excitatory activity in the brain are the PET scan and the MRI. According to Kalat (2004), these methods are non-invasive, meaning that they don’t require the insertion of objects into the brain, yet they yield results that allow researchers to record brain activity. The PET scan (positron emission tomography) involves the researcher injecting a radioactive chemical into the patient’s body, which is then absorbed mainly by the brain’s most active cells. With the use of radioactive detectors, placed around the patient’s head, a map is produced that shows which areas of the brain are most active.

  • Cracking The Alzheimer's Code By Linda Marsa

    To find the culprit to stop tau proteins and amyloid peptides to function improperly, scientists realized that studying brains at an earlier age when they are alive would be best in their search to find a cure. Studying living brain tissue would introduce a lot more discoveries that dead brain tissue would not offer. Techniques like magnetic resonance imaging (MRIs) and position emission tomography (PETs) are actually not as helpful in studying living brain tissue because they can provide up to a millimeter of focus on the brain but that would not be adequate to find the formation of the plaques and tangles which need more concentration to about a tenth of a milliliter. But there are new tools like the multi-photon confocal microscope that is better and more precise in looking at brain activity. Also the approval of Amyvid by the FDA has allowed for easier visuals on PET scans because its purpose is to dye the amyloid proteins that could not be seen in regular PET scans. From these astounding innovations, scientists are close to developing genetic tests that could determine the risk of an individual developing Alzheimer’s

  • Stroke Case Study

    1138 Words  | 3 Pages

    Even if the physical symptoms of a stroke are obvious, brain scans should also be carried out to determine if the stroke has been caused by a blocked artery (ischaemic stroke) or burst blood vessel (haemorrhagic stroke), which part of the brain has been affected, and how severe the stroke is. Different treatments are required for the different types of stroke, so a rapid diagnosis will make treatment more straightforward. Further tests on the heart and blood vessels might be carried out later to confirm what caused your stroke. In some cases, another type of ultrasound scan called an echocardiogram may be carried out to produce images of your heart and check for any problems with it that could be related to your stroke.

    When it comes to death, everyone has a different perspective about it. One might think death is just a beginning, a key to open the door to the afterlife. A release, a way out to a different world. Others might think that death is simply a lesson of life. It teaches one not to waste his or her time but live to enjoy it, while it still last. Live and do whatever one desire before time runs out. Surely, death has many different purposes and meanings. In the short story “Bullet in the Brain” by Tobias Wolff. He uses death as a flashback and a final thought to show the reader the character’s life in the story. In the “An Occurrence at Owl Creek Bridge” by Ambrose Bierce, he uses death to teach the reader that one should stand up and protect the

  • CT-scanner

    CTscans stands for “Computed Tomography”. It is a way of looking inside your body using a special camera. It is an advanced scanning x-ray and computer system that makes detailed pictures of horizontal cross-sections of the body, or the part of the body that is x-rayed. A CT scan is a diagnostic test that combines the use of x-ray with computer technology. A series of x-beams from many different angles are used to get these cross-sectional images of the patient’s body. In a computer, these pictures are assembled into a 3-dimentianal picture that can display organs, tissues, bones, and any such thing. It can even show ducts, blood vessels and tumors. One of the advantages of CT is that it clearly shows soft tissue structures (such as brain), as well as dense tissue structure (such as bone). The pictures of a Ctscanner are a lot more detailed than the pictures of a regular X-ray machine. It can make pictures of areas protected or surrounded by bones, which a regular X-ray machine can not. Because of this, a CT scanner is said to be 100 times as affective and clever as an ordinary X-ray, and can therefore diagnose some diseases a lot earlier and quicker. It is recent technology that has made it possible to accurately scan objects into a computer in three dimensions, even though the machines and ideas were developed in the 1970s. In the 70s doctors started to use this new type of machine that could give detailed pictures of organs that the older type of x-ray, machine could not give.

  • Neurological Assessment

    1456 Words  | 3 Pages

    Paramedics are frequently presented with neurological emergencies in the pre-hospital environment. Neurological emergencies include conditions such as, strokes, head or spinal injuries. To ensure the effective management of neurological emergencies an appropriate and timely neurological assessment is essential. Several factors are associated with the effectiveness and appropriateness of neurological assessments within the pre-hospital setting. Some examples include, variable clinical presentations, difficulty undertaking investigations, and the requirement for rapid management and transportation decisions (Lima & Maranhão-Filho, 2012; Middleton et al., 2012; Minardi & Crocco, 2009; Stocchetti et al., 2004; Yanagawa & Miyawaki, 2012). Through a review of current literature, the applicability and transferability of a neurological assessment within the pre-hospital clinical environment is critiqued. Blumenfeld (2010) describes the neurological assessment as an important analytical tool that evaluates the functionality of an individual’s nervous system. Blumenfeld (2010) dissected and evaluated the neurological assessment into six functional components, mental status, cranial nerves, motor exam, reflexes, co-ordination and gait, and a sensory examination.
