Common Etiologic Model

There is no known specific pathophysiology that is associated with Bipolar spectrum disorder, nonetheless, it’s thought that this disorder arises from many areas such as, genetic, physiological, environmental, epigenetics and psychosocial

Bipolar disorder also known as manic depressive illness is a brain disorder that causes shifts in mood, energy, activity levels, and the ability to carry out everyday task (National Institute of Mental Health, 2016). Every year, 2.9% of the U.S population is diagnosed with bipolar disorder, with nearly 83% of causes being classified as severe (NAMI). According to Miller, Ghadiali, Larusso, Wahlen, Ani-Barron, Mittal, Greene (2015), bipolar disorder is the leading cause of disability worldwide. Most people that experience this disorder experience highs and lows of the illness. In this paper, various components of bipolar disorder will be discussed. The components include: population dynamics, physical illnesses that accompany the disorder, risk factors and social determinants, treatment, prevention, health promotion, and cultural differences found globally.

Bipolar disorder is a brain illness caused by an underlying problem with specific brain circuits, and the balance of brain chemicals called neurotransmitters. Doctors have imaging tools such as (FMRI) which stands for Functional Magnetic Resonance Imaging, and (PET) which stands for Positron Magnetic Resonance

Nusslock is a professor at Northwestern University. After graduating with a Ph.D. from University of Wisconsin-Madison, he went on to study neuroscience at Pittsburg medical school. This journal focuses on how criteria regarding bipolar disorders may fail to include milder bipolar syndromes. The main argument is the criteria for diagnosing mental illnesses, such as bipolar disorder, is not adequate. He argues there is no reliable criteria equipped for diagnosing mild cases of bipolar disorder. Mild bipolar disorder is significant and should not go unnoticed, argues Nusslock. “Individuals with major depressive disorder (MDD) who display subsyndromal hypomanic features, not concurrent with a major depressive episode, have a more severe course compared to individuals with MDD and no hypomanic features, and more closely resemble individuals with bipolar disorder on a number of clinical validators,” claims Nusslock. His findings prove what he hypothesized. The article gives the reader an insight to how important subtle symptoms are and how no person or behavior deserves to go unnoticed. He suggests there is a fault with how we are diagnosing bipolar disorders. We tend to group patients into a larger category, rather than finding a diagnosis that fits properly. The evidence in this article is a combination of research and Nusslock’s own ideas. Because he is able to combine thoughts and ideas, the information is more reliable. This article may be biased because he seems to be solely talking about his perspective than the opposite perspective. Nusslock continuously reflects on his strong sense of opinion. He seems to be very passionate about bipolar disorder and wants to be a part of making a difference. In my opinion, the information is reliable for one side. It does not show reliability for an opposing opinion because there seems to be no other opinion present. This article is a

Unlike the MRI, the fMRI is used to understand brain activity and function over developmental time and in real time a. Point 2: Which is most used among Psychologists and Neuroscientists - Though these are not the only ways we can study the brain, these are the main ones we use in psychology and neuroscience. - In psychology and neuroscience, not a lot of studies are done using an MRI, because it has limitations and can only really show us the anatomy of the brain and maybe if there is any kind of brain damage. Based on information from Mayo Clinic 2012, the popular method of research involving brain imaging techniques these days is using the EEG, paired with what is called a Brain Computer Interface. Since there are always electrical signals going on in the brain, its really hard to pinpoint a reaction. So computers were coded to give a particular output whenever there is a specific electrical response in the brain.

A characteristic related across all mood states is the over activation of the prefrontal cortex. Malfunctions in the frontal cortex may lead to the dysregulation of moods. Mistransmissions on how to react to a situation is a leading possibility to bipolar. Another study shows that the prefrontal cortex of teenagers and young adults have a correlation of abnormalities over time between volume and age. Studies have seen that abnormal connections in the frontal lobe to the limbic system is a factor in bipolar episode changes. (Townsend)

The severe mood fluctuations of bipolar or manic-depressive disorders have been around since the 16-century and affect little more than 2% of the population in both sexes, all races, and all parts of the world (Harmon 3). Researchers think that the cause is genetic, but it is still unknown. The one fact of which we are painfully aware of is that bipolar disorder severely undermines its' victims ability to obtain and maintain social and occupational success. Because the symptoms of bipolar disorder are so debilitation, it is crucial that we search for possible treatments and cures.

There are many concerns when it comes to the mental health of individuals throughout the world. Mental health problems can manifest in a variety of different ways and range in severity from attention deficits to hallucinations. One of the most severe forms of disorders that can affect an individual is bipolar disorder. Bipolar disorder is a brain disorder that presents a wide variety of different symptoms that affect the ability of an individual to live a complete and satisfied life. By examining the overall prevalence of the ailment, its symptoms, and the forms of treatments available, a more complete understanding of bipolar disease can emerge.

Bipolar disorder, also known as manic depressive disorder, is defined as “a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks” (1). According to the Depression and Bipolar Support Alliance, this disorder affects approximately 5.7 million people age 18 and older in the United States annually (2). There are a few different categories of this disorder including Bipolar I Disorder, Bipolar II Disorder, and Cyclothymic

Bipolar is a mental disorder which is known for a brain disorder that causes constant changing of moods, activity levels, and the ability to carry out every day activities, relationships with family and friends and possibly workplace functioning. The areas that the brain is affected by bipolar is the frontal and temporal lobes of the forebrain, the prefrontal cortex, the basal ganglia, and parts of the limbic system (Bressert, 2007). The hippocampus may also play a role in bipolar disorder, as structural changes to this area of the brain have been associated with this disorder in some individuals. It is also known by its older name “manic depression” (Bressert, 2007). A manic episode is described to be like feelings of intensified energy levels, creativity, and euphoria are common. People that experience a manic episodes talk a mile a minute, hardly sleeps, and are hyperactive; they may also feel that they’re all-powerful, invincible, or destined for the best (Bressert, 2007). Bipolar is described as an emotional roller coaster. A person that is diagnosed with bipolar will experience highs that are known as manic episodes and lows that are known as depression (Bressert, 2007). These periods have different lengths of time, they can last for a few hours or ranging days or possibly even longer; they can last up to a few weeks up to months at one given time. This disorder is a long term and chronic condition with a variety of treatments.

Bipolar disorder, according to the National Institute of Mental Health (NIMH), is “a brain disorder that causes unusual shifts in mood, energy, and activity levels,” and

2. Functional brain mapping (scanning a person's brain while he or she is performing a certain physical task such as squeezing a ball, or looking at a particular type of picture) is helping researchers better understand how the brain works.
