Millions of individuals are affected and living with bipolar disorder everyday. Bipolar disorder is present in approximately 5.7 million American adults, or an equivalent of 2.6 percent of the US population (Kerner, 2014). Bipolar disorder is also known as “manic depression.” It is a mental disorder that is marked by the constant changing of moods. Most of the time it goes from periods of depression to periods of being extremely happy or being very irritable. Bipolar disorder is a common,…

with schizophrenia, compared to the brains of those without the disease, the most accepted hypothesis among today’s researchers is that schizophrenia is a brain disease. For example, brain –imaging technology, including such methods as positron emission tomography (PET) scans, have identified reductions in metabolic activity in the frontal cortex of people who have been diagnosed with schizophrenia. E. Genetics The question genetic researchers start with is: Does schizophrenia run in families?…

certain specific effects on brain function to include brain structure. In addition, specific areas of the brain which are said to be vulnerable to sleep loss have been monitored with the utilization of magnetic resonance imaging (MRI) and positron emission tomography (PET). Keep in mind that these types of studies have mainly focused on working memory and functions which require a significant amount of attentional…

Synesthesia: Crossed Responses to Inducers and Who is Affected Sylveria McCue Red Rocks Community College Abstract Synesthesia is a condition where the brain crosses the signals from the five senses resulting in letters, numbers, and words having colors, tastes having the feeling or vision of shapes in a synaesthetes mind, and sounds including physical responses of pain or pleasure. Acute studies on grapheme-color synesthesia provides the most research on who has this condition. Once believed…

There are several different categories of depression. Major depression is a very familiar term and is the most well known form of depression.

A lot of people want to blame the parents of the offenders, asking “what did you turn your child into?” 36% of serial killers were physically abused, 26% were sexually abused, and 50% were psychologically abused (Mitchell and Aamodt 45). Many people have logically come to the conclusion that just because someone is abused, it does not mean that they will become a serial killer; or even a murderer; which is true. In the general population (people who have never committed murder) only 6% are…

The positron emission tomography indicated the same result, and since dopamine is a neurotransmitter, it affects the processes of the brain that control movement, emotional response and ability to experience pain and pleasure. The evident contributing to this disorder…

Eating grocery-store food is not currently viewed with suspicion, whereas a hand-prepared, foraged meal raises eyebrows. How do chemicals, shiny steel factories, and tin cans make us feel more secure in the buccal insertion of chemical-laden foodstuffs? How did we get to the point where, unless, it comes from a can, box, or bag, food is suspect? Now, I don’t advocate blaming everything on the government. But this phenomenon does stem, at least partially, from governmental interference. Yet,…

Cancer Medicine (Oncology) Cancer cells arise from different normal cells, thus when the normal cells become abnormal, it allows the cancer cells to grow out of control. Cancers can start almost anywhere in the human body, it can occur in any tissue and at any time of life, but mostly, elders have the highest risk. Cancers are called neoplasm because neoplasm is new growths that arise from normal tissue. Furthermore, there are two different characteristics of neoplasm: benign and…

Discuss the physical assessment of a patient who presences with the complaint of cervical lymphadenopathy. “Lymphadenopathy is characterized by enlarged lymph nodes. Lymph node enlargement is caused by an increase in size and number of its germinal centers caused by proliferation of lymphocytes and monocytes or invasion by malignant cells. Normally, lymph nodes are not palpable or are barely palpable. Enlarged lymph nodes are characterized by being palpable and often may be tender or painful to…
