Bipolar Brain Chemistry The central nervous system is a collection of cells within the brain specialized to send specific signals throughout the body in order to relay the messages necessary for proper functioning. The way these cells, also called neurons, communicate with one another is through the process of releasing neurotransmitters. A balanced proportion of neurotransmitters are crucial for a healthy functioning mind. In situations where the neurotransmitters get out of sync by becoming too prevalent or sparse within the synaptic clefts, a wide spectrum of mental illness can be the result. Manic-Depression, also known as Bipolar disorder, is an example of the malfunctioning neurons responsible for the regulation of certain neurotransmitters. Through a critical analysis of this glitch in the system, one can attempt to further understand one aspect of the bipolar brain, as well as understand how certain medications may work to alleviate symptoms. In order to understand the effects of said malfunctions, it is vital to brief crash course in what it means to be bipolar. This disorder is typically characterized by periods of intense mania, followed closely by deep, unadulterated depression with “mixed” periods sprinkled throughout. Manic periods are characterized by intense feelings of euphoria. This may seem like a positive, however these phases typically lead to bouts of impaired judgment. Behaviors can become grandiose in nature and look extremely hyperactive. The person may have raised libido, want to stay up all night, and exhibit overall decreased inhibition. The depression that follows these bouts of ecstasy comes quickly, and they are both dark and unforgiving. Individuals with bipolar disorder lack a middle groun... ... middle of paper ... ...

Depression is one of the most prevalent mental health conditions in the U.S. that affects, men, women, teens and even the elderly. Most of the time depression goes unrecognized or even untreated. It may be normal for people to experience feelings of sadness or anger for short periods of time. Usually this may last a few days due to temporary circumstances that may happen in an individual’s life, but if these feelings occur for an extended period of time, it may be a sign of major depression. Bipolar disorder may be confused with major depression. An individual having recurring depression and mania for an extended period differentiates bipolar disorder. As a healthcare professional, it is important to educate individuals and their families who have a mental health illness so that they can pay attention to important cues so that they can be addressed properly. This case study refers to a female patient diagnosed with bipolar disorder. The Diagnostic and Statistical Manual of Mental Disorder (DSM-V) is a publication/diagnostic tool, used by healthcare professionals to diagnose mental disorders (Psychiatry Online, n.d) Bipolar disorder may be confused with major depression. Bipolar disorder is differentiated by an individual having reoccurring depression and mania for an extended period of time. These episodic mood shifts can lead to excessively elevated or irritable mood. Many believe that this disorder can lightly stem from a combination of genetic and non-genetic factors (WebMD, 2014). According to statistics, the average onset for bipolar disorder is in the mid-to late 20s, but over the years the average age has been decreasing. The prevalence of bipolar is approximately 2.6% in the population at large with 82.9% of these cases cl...
Bipolar disorder involves going from a state of extreme happiness or concentration to a major depressive state and back to “normal.” Depending on the individual in question, the three states may come in various orders and lengths. For example, the upward swing or the elated feeling of bipolar disorder can last from a week to a few years. The same can be said about the major depressive part of bipolar disorder. The exact length of each state of mind varies amongst each individual. For those who have manic episodes, this can involve intense feelings of being on top of the world or they may indulge in spending recklessly with a lack of consideration of friends and family. Therefore, the bipolar person’s friends and family may feel the need to pay off his or her debts. Unlike manic episodes, people with hypomanic episodes experience extreme concentration and have personal insight. Hypomanic people have the capability to listen to their friends and family. For example, people in a hypomanic state may have the energy to write a book in a single night. Over the last five years, bipolar disorder has been on the rise in the media. More and more stories about bipolar are being published in the newspaper, films, television, and online videos, and passed on through word of mouth. More often than not, these stories involve people who are exhibiting bipolar traits. Although bipolar disorder does have some negative parts to it, the stories portrayed in the media often involved only the most severe bipolar cases. Therefore, messages in the media often involve myths. Certain sources do not involve myths but have the potential to cause misinformation. Media messages can become biased. There are many bipolar disorder myths that come from word of mou...
For the future, a yearlong study of at least 10 bipolar drugs are being conducted and compared to figure out the best combinations (Kluger and Song, 2002). Brain scans are also being completed to determine which lobes and regions are involved in Bipolar Disorder (Kluger and Song, 2002). A blood test that allows bipolar disorder to be spotted just as simply as high cholesterol is a process in the making (Kluger and Song, 2002). A blood test will finally eliminate years of incorrect diagnoses, along with misguided treatments (Kluger and Song, 2002).
Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks, which can impair the individual's ability to function in ordinary life. Symptoms of bipolar disorder are severe. They are different from the normal ups and downs that everyone goes through from time to time (Bressert, 2006). Bipolar disorder symptoms can result in damaged relationships, poor job or school performance, and even suicide. But bipolar disorder can be treated, and people with this illness can lead full and productive lives. Treatment commonly includes mood stabilizing medication and psychotherapy (Smith & Segal, 20...
Manic Depression is also referred to as Bipolar Disorder and Severe Mood Swings. It is the severe alternate from unexplainable depressed feelings, thoughts, and actions to elevated personal feeling of euphoria. This disorder often causes dysfunction with family members, personal relationships, work, and legal system (Mallozzi). This causes sever fluctuation in mood or poles, from depression to mania. Half of all the cases of this disorder start when patients are between the ages of 15 and 25. Manic Depression affects 2.4% of the world (Nordqvist).

Bipolar disorder is also known as manic-depression disorder, may cause unusual changes in mood and behavior such as grandiosity, decreased energy, distractibility, diminished interest, insomnia, pressured speech, suicidal thoughts, and decrease in the ability to carry out day to day tasks (Diagnostic and Statistical Manual of Mental Disorders; 5th Ed.; DSM-5; American Psychiatric Association, 2013). According to Jann (2014) the symptoms of bipolar disorders are severe alternating between normal ups and downs leading in damaged relationships, poor job and school performance, and even suicide among the most severe. There are four types of bipolar disorder which include bipolar I disorder, bipolar II disorder, bipolar disorder not otherwise specified, and cyclothymic disorder Jann (2014).

I've always had complicated feelings about mental illnesses. It isn't necessarily something I would think about too much, but that the fact that I was lectured plenty of times on depression, ocd, bipolar disorder etc., but I was never taught on why it occurs. Why does people become such a different person? Most importantly, why does it occur? Mental illness is probably one of the most misunderstood illness, in terms of . At one time it was an illness that no one would dare talk about. It was an illness to be ashamed of and many patients were secretive about them. But now, things have changed and there is more research done and a much greater understanding. Research for mental illnesses are still quite limited simply because of the brain’s complexity. The brain may well be our body's most mysterious organ. Extremely fascinating, and an intensive study topic, we're left wondering: What exactly does the brain do and how? Despite years of intensive research, along with impressive technological advances, answers to many of our questions about the brain are still distant. The reason is quite simple: the brain contains more than ten billion cells interacting with each other through many connections ("Neuroscience Introductory"). It can be thought of as the total human population on Earth and all their interactions with each other. Imagine how much interactions there are among 10 billion different cells and how hard it is to find
