Randy has been experiencing several disturbing symptoms over the last year including: muscle weakness, slow reaction time, visual perception issues, seizures, hearing loss, weight gain, a general sense of pain, and delusions.
explain why his doctors might be concerned with the following when making their diagnosis:
neurotransmitters
hormones
myelin sheath
occipital lobe
temporal lobe
describe how each of the following brain scanning techniques would aid the doctors in making their diagnosis of these symptoms:
pet scan
fmri
eeg

Using the scanner allows accurate diagnoses to be obtained. The procedure is not invasive, and adds points to the quality of care given to animals.

Functional magnetic resonance imaging (fMRI) is a non-invasive and safe technique for measuring and correlating brain activities during normal as well as sick conditions. Measure changes in the blood flow of the brain.

An electroencephalogram (EEG) is a study that detects the electrical activity of the brain using small fixed electrodes. Brain cells communicate through electrical impulses and are active all the time.

Explanation:

With the scanner the body of the patients can be observed internally, without opening them. Unlike ultrasound and radiography, it favors the virtual tour through each of the organs. Thanks to this reconstruction of bi and three-dimensional images, the analysis of blood vessels and respiratory tract is possible. Another aid of the use of the scanner is the detection of pathologies in the bone tissue. It can be used to follow up on certain clinical treatments.

FMRI is a technique used in radiology that produces high-resolution images with good contrast between various brain tissues. The change in blood flow is a very sensitive indicator of altered nerve activity.

An EEG is able to determine changes in brain activity that may be useful for diagnosing brain disorders, especially epilepsy or other seizure disorders. An EEG can also be useful for diagnosing or treating the following disorders:

• Brain tumor

• Brain damage from head injuries

• Brain dysfunctions that can have various causes (encephalopathy)

• Inflammation of the brain (encephalitis)
