Bipolar Disorder
Genetics, Brain Structure & Behavior
Bipolar disorder is biological problem which affects the brain that causes unusual shifts in mood (Kowalski & Westen, 2009). It is also known as manic-depressive illness. Bipolar disorder is different than regular mood swings and daily ups and downs of the average person's life. Bipolar disease typically develops in late adolescent and early adulthood and is treatable; currently there is no cure for this disorder (NCBI, 2010). In this paper we will discuss bipolar disorder and the brain, behaviors associated with bipolar disorder, genetic links, causes, prevention, treatment, national and international occurrences.
Bipolar Disorder and Behavior
Bipolar disorder causes dramatic mood swings, the individual goes from a state of mania to a state of depression. Mania is the part of the disorder where the individual has an overtly high amount of energy. A diagnosis of mania is made when the patient exhibits three or more of the following signs for the majority of the day ("Bipolar disorder," 2002), for at least a week:
Increased energy, activity, and restlessness
Excessively "high," overly good, euphoric mood
Extreme irritability
Racing thoughts and talking very fast, jumping from one idea to another
Distractibility, can't concentrate well
Little sleep needed
Unrealistic beliefs in one's abilities and powers
Poor judgment
Spending sprees
A lasting period of behavior that is different from usual
Increased sexual drive
Abuse of drugs, particularly cocaine, alcohol, and sleeping medications
Provocative, intrusive, or aggressive behavior
Denial that anything is wrong
Depression is the part of the disorder where the patient experiences the opposite effects of mania. According to Bipolar Disorder ("Bipolar disorder," 2002) a diagnosis of a depressive episode can be concluded when a person exhibits five or more of the following symptoms lasting the majority of the day for at least two weeks or longer:
Lasting sad, anxious, or empty mood
Feelings of hopelessness or pessimism
Feelings of guilt, worthlessness, or helplessness
Loss of interest or pleasure in activities once enjoyed, including sex
Decreased energy,...
Bipolar psychiatric disorder (BD) -- which is characterized by "…cycles of depression and mania" -- is a "euphoric, high-energy state" that can produce remarkable bursts of creativity or, on the other hand, can produce erratic behavioral events that are risky and provocative (Gardner, 2011). About 2.4% of the world's population has been diagnosed with bipolar disorder (at one time or another in their lifetime) but the rate in the United
Bipolar I disorder is an axis 1 clinical disorder in the DSM-IV and is a serious mental illness that can lead to suicidal ideation or action. The history of bipolar disorder research is a long one, and understanding of the disease has deepened considerably over the last several generations. Diagnosis of bipolar disorder 1 is complicated by its resemblance to other mood disorders, mainly major depression but also psychotic disorders
Disorders of the Brain Alzheimer disease This is a progressive disease that damages nerve cells (neurons ) in parts of the brain that are involved in learning, memory, reasoning and language.as the disease progresses, there is a communication breakdown among the neurons.in the early stages of the disorder short-term memory starts failing .with time functions like language, long-term memory and judgment gradually decline. This disorder is a very common cause of dementia
Disorders in Older People Alzheimer's and Eating Disorders and how they affect Older Adults Alzheimer's and Eating Disorders and how they affect Older Adults Disorders in Older People Alzheimer's-Type Dementia Eating Disorders Disorders in Older People In considering the general health of the population, the larger elderly population does not necessarily imply that most of them live or are ill from severe disabilities. Age related disorders would occur to different people early or late in their lives.
Genetics and Development Genetics is a scientific discipline that deals with how individuals inherit their physical and behavioral attributes. Generally, genetics is a branch of biology that deals with the science of heredity, genes, and differences in living organisms. It's the process with which a child inherits traits from his/her parents and the molecular organization and function of genes. The question of what determines the development of a child has been
Genetics and Development: As a discipline of biology, genetics is basically considered as the science of genes, inheritance, and differences in living organisms. Since genes are common characteristics in living organisms, genetics is used in the study of all living systems including plants, humans, domestic animals, bacteria, and viruses. Generally, this biological discipline focuses on the molecular structure and operation of genes whose behaviors are in the context of organisms or
