3. Chronic Traumatic Encephalopathy (CTE) is a progressive and chronic disease of the brain found in athletes with a history of repetitive brain trauma. 4. Subdural Hematoma (SH) is when a blood clot develops between the dura (the lining between the skull and the brain) and the brain after a severe head injury. Statistics that support the occurrences of head injuries are as follows according to National SAFE Kids Campaign and the American Academy of Pediatrics (Gfeller Foundation).
The participants were shown 60 words one by one. After each word they were asked questions about the word. The questions required structural, phonetic or semantic processing. For example, a question for structural processing asked whether the word was written in upper or lower case letters, a question for phonetic processing asked whether the word rhymed with another word, and for semantic processing the participant had to decide whether the word fitted into a sentence. A further 120 words were then added to the original 60 words.
This information enters the sensor memory. This piece of information then gets encoded by one of our five senses (smell, touch, taste, hear and feel) depending on the type of information. If enough attention gets paid to the information piece then it will enter the short term memory which has a capacity of “the magic number 7, plus or minus 2” which has a duration of 15 to 30 seconds before the memory decays. The short term memory codes for all information acoustically (according to the sound). If the information in the STM store happens to be visual then it gets encoded/transformed into acoustic codes.
That is myelin, the fatty layer that surrounds each fiber of the nerve. It is the nerve that transmits visual information from the eye to the brain. 1. List two functions of the sclera. •___________________________
Hedge reports that strokes occur every forty-five seconds and more than 300,000 people suffer a permanent disability yearly. Holland et al., (1996), describes aphasia and the effects on the PWA’s intellect, and incapacitated social and family life. This research examines the validity of the treatment of auditory comprehension in persons with Aphasia. Since past research has yet to validate, and substantiate evidence-based practice (EBP) in this particular area, this literature review will illustrate the etiology, characteristics and, if found within the study design, the clinical relevance of treatments considered and provided for the debilitating disorder of AC in PWA. ETIOLOGY According to Hedge (2008), the leading cause of strokes may be due to years of vascular disorders.
Visuo-spatial scratch pad is the inner eye, it is where you see it in your brain. It holds and manipulates visual and spatial information and relies on a visual code, e.g. colour, shape and size. The visual component deal with what the object looks like and holds the information encoded from the verbal stimuli, and the spatial component allows us to monitor where about it is in relation to other objects. And due to the limited capacity it is difficult to perform several visuo-spatial tasks at the same time.
The frontal lobe’s main functions are movement control and language production that thrive from the primary motor cortex. Whereas Wernicke’s area is located on the left side of the temporal lobe, called superior temporal gyrus, that is link with the auditory cortex, which associates memories, comprehension of language, emotion, and sensory input. There is a difference in aphasia between Broca’s and Wernicke’s area. Once the Broca’s area is damaged the person would have
UNDERSTAND THE PROCESS AND EXPERIENCE OF DEMENTIA Task A 1. For each of the following forms of dementia, describe: • How is the brain affected • The symptoms an individual might experience. Alzheimer's disease is a degenerative brain disease. Most patients start exhibiting symptoms after they reach the age of 60. Alzheimer's disease affects the brain through exponentially greater cell death and tissue loss, resulting in a decreased brain size.
Schizophrenia and Its Effects on the Hippocampal Region of the Brain Schizophrenia is a serious mental disorder, afflicting approximately 1 percent of the world’s population. It is characterized by hallucinations, delusions, thought disorders, social withdrawal, lack of initiative and persistence, anhedonia, speech poverty, deficits in learning and memory, poor abstract thinking, etc. (Carlson, 2010). The onset of symptoms typically occurs in young adulthood. It is followed by the loss of brain tissue.
When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6. Which term best describes this value: average, mean, median, mode, or standard deviation? Answer: 9.6 is the average of the numbers listed and is also the mean of this data. 4. Answer the next four questions using the following set of numbers.
