Neuropsychological testing:
Neuropsychology is a field with historical origins in both psychology and neurology. The crucial activity of neuropsychologists is to assess the brain functioning, through prearranged and organized behavioral observation. Neuropsychological tests are designed to look at a variety of cognitive capabilities, which involves speed of information processing, attention, memory, language, and decision-making functions, which are essential for goal-directed behavior. By testing a multiple of cognitive abilities and examining patterns of performance in different cognitive areas, neuropsychologists can make conclusion about fundamental brain function. Neuropsychological testing is an important constituent of the assessment …show more content…

Items including a tuning fork, flashlight, reflex hammer and needles are used to help in diagnosing brain tumors, infections such as encephalitis and meningitis, diseases such as Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis and epilepsy. Some tests require the services of a specialist to perform and analyze results.
Neuropsychological assessment provides both general and specific information about current levels of cognitive performance. An average or multiple score across multiple ability areas provides a general guide of how well a person functions cognitively at the current time. Based on the result of a neurological test, physical assessment, patient history, x-rays of the patient’s chest and skull, and any previous testing, physicians may order one or more of the following diagnostic tests to determine the specific nature of a assumed neurological disorder or injury. These diagnostics generally involve either nuclear medicine imaging, in which very small amounts of radioactive materials are used to study organ function and structure, or diagnostic imaging, which uses magnets and electrical charges to study human …show more content…

Neurological uses include the diagnosis of brain and spinal cord tumors, eye disease, inflammation, infection, and vascular irregularities that may lead to stroke. MRI can also detect and monitor degenerative disorders such as multiple sclerosis and can document brain injury from trauma.
Functional MRI (fMRI) uses the blood’s magnetic properties to produce real time images of blood flow to particular areas of the brain. An fMRI can pinpoint areas of the brain that become active and note how long they stay active. It can also tell if brain activity within a region occurs simultaneously or sequentially. This imaging process is used to assess brain damage from head injury or degenerative disorders such as Alzheimer’s disease and to identify and monitor other neurological disorders, including multiple sclerosis, stroke, and brain tumors.
Myelography involves the injection of a water- or oil-based contrast dye into the spinal canal to enhance x-ray imaging of the spine. Myelograms are used to diagnose spinal nerve injury, herniated discs, fractures, back or leg pain, and spinal

1. Write a brief introduction about the diagnostic imaging modality. Nuclear medicine is a section of medical imaging that uses radioactive medication known as radiotracers or radiopharmaceutical (Understanding nuclear medicine, 2009). Radiotracers are given to the patient through injection, swallowing or inhalation, which makes the body radioactive for a short time. The radiation is detected by a special camera, and then the image is produced.

This is a serious disorder that can cause people people to be a risk to themselves as well as others. Being bipolar needs to be taken serious.

Standardized intelligence testing has been one of psychology’s ultimate achievements. “Intelligence tests are psychological tests that are designed to measure a variety of mental functions, such as reasoning, comprehension, and judgment.” ("Intelligence tests," n.d.) They can help diagnose knowledgeable disabilities or measures a person’s knowledgeable potential. Alfred Binet was the first French Psychologist who created the first intelligence test in the 1900s.

In the science of psychology, an individual can specialize in many different areas within this type of study. For a form of psychology to be considered as a “specialty” it must follow the guidelines that the American Psychological Association, APA, have set. The APA will only recognize a form of psychology if it is counseling, clinical, industrial or organizational, and school psychology. Any that are outside of the following forms of psychology are considered as sub-fields or areas of concentration (Specialties). An example of a specialty within psychology is Neuropsychology.

Radiology is a tool frequently used in medicine. Almost everyone will have an X-ray, ultrasound, MRI, or one of any of the many other imaging techniques at some point. The use and development of various radiologic techniques have reduced the need of exploratory surgeries and given us a better idea of what is going on inside our bodies. Radiology as we know it today was was invented over a century ago by a German physicist and Professor named Wilhelm Conrad Roentgen 1. In 1895 he discovered electromagnetic radiation in in a wavelength range, or the X-Ray.

Some advantages of this technique are that there is no radiation involved, it is good at visualizing soft tissue, and that since it can visualize soft tissue so easily it can identify a multitude of different problems. Some disadvantages are that it is time consuming, expensive, and there is extensive training needed to operate it. The last type of imaging technique that will be covered is conventional radiography which can detect foreign bodies and changes or lesions of the skeletal system and is used when the corpse cannot fit into the CT machine. The advantages of this technique are that it is simple, quick, and cost efficient. However, it uses radiation, cannot make three-dimensional reconstructions, has a superimposed image, and it cannot visualize soft tissue
