Neurodegenerative diseasesA well-oiled machinery consists of a complex and complex system: there are well-organized processes, mechanisms within the device work efficiently, and several processes work simultaneously to then fulfill various functions. What happens if there is a problem with the machine? When something goes wrong, such as connections between complex processes, that don't happen, the machine doesn't work properly. In some cases, there is no adjustment or fallback mechanism. At this point, the damage may be irreversible and the machinery is no longer salvageable. [However, it can illustrate the interactions and processes within the complex machinery.] The human brain can respond in much the same way. Neurodegenerative diseases are telltale signs of a “problem” in the brain’s neuronal mechanical processes. Thus, pathological problems of the brain demonstrate how the brain controls movement and behavior. This is reflected in physical and emotional behavior. (5) It also illustrates the interaction between the central nervous system and the peripheral nervous system. There must be connections between the brain's neuronal activity and the rest of the central and peripheral nervous systems. An illustration of the brain can also be understood as a “box” made up of small interconnected boxes. These integrated boxes in turn demonstrate the concept that “Brain = Behavior = Being”. The purpose of this essay is to provide a general overview, as well as a neurological overview, of the neurodegenerative disease, Creutzfeldt-Jakob disease. In doing so, it will show how the brain turns out to be the center of behavior and creates the individual's feeling...... middle of paper ...... The fact that an individual's neural communication is interrupted and ended up stopping everything. control of bodily functions is evident. Knowing that a person's brain is "riddled with holes" from an infectious protein particle is speculative. Although many believe that an individual is much more than just neural connections, motor symphonies, neurotransmitters, and selective permeability, Creutzfeldt-Jakob disease puts a new spin on individual identity. Ultimately, patients or their loved ones do not focus on the facts and figures about CJD. Their reality is that an individual slowly disintegrates before their eyes, the sense of “Self” is lost. .ac.uk/intro.htmhttp://www.cjd.ed.ac.uk./lancet.htmDelcomyn, Fred.
