through many changes as we age just like the rest of our bodies. Alzheimer Disease is a progressive loss of structure‚ function and death of neurons which gradually declines the cognitive abilities that affects multiple systems. AD affects the cerebral cortex which is the outer and main part responsible for memory‚ learning and reasoning‚ language resulting in destroying the qualities that forms an individual’s distinctive character. When compared‚ many fewer nerve cells and synapses are found in Alzheimer’s

can play a part in the onset. The decreased size of the cerebral volume causes the brain to function differently as well. For example‚ children with BSD also have a hyperactive amygdala and a hypoactive prefrontal cortex (Weis‚ 2014). The amygdala is responsible for the brain’s “fight or flight” reflex and since it is more sensitive than normal‚ this can cause problems like developing phobias or acting out repeatedly. The prefrontal cortex‚ which is in charge of helping us overcome our fears are

abstinent users showed no deficits in performance on the modified version of the Stroop task when compared to the comparison group. They also found that despite the lack of performance differences‚ the anterior cingulated cortex and the left lateral prefrontal cortex had hyperactivity in the hippocampus bilaterally‚ when compared to the comparison group. The results suggested that users display persistent metabolic alterations in brain regions responsible for executive cognitive functioning

Homeostasis Why might the special senses of smell and taste be important for helping to maintain homeostasis in the body? The French scientist Claude Bernard first suggested the concept of homeostasis in the 19th century. He defined homeostasis as the fact that all living things maintain a constant internal environment. Homeostasis is the tendency of the body to maintain a relatively consistent internal state. The nervous system sends and receives signals about temperature‚ hydration‚ blood

Compare the effectiveness of neuroimaging approaches to predict the future onset‚ and to differentiate between the different clinical stages‚ of Alzheimer’s disease Alzheimer’s disease is characterised as a dementia with the presence of amyloid plaques and neurofibrillary tangles which leads to neuronal cell death (Hardy & Higgins‚ 1992). The most major symptom shown in Alzheimer’s disease is the degeneration of cognitive function (memory‚ reasoning‚ attention‚ language etc.) and it is crucial to
