An interesting topic to discuss is bipolar disorder. Bipolar disorder is defined as “a disorder involving periods of disabling depression alternating with periods of extreme euphoria and excitement” (Hockenbury & Hockenbury 578). Bipolar disorder has the same symptoms as depression and then goes through a period of mania. Additionally, you can still receive a diagnosis of bipolar disorder if you only experience manic episodes (Hockenbury & Hockenbury 578). The manic episode can last several days and is generally shorter than the depressive state. During the manic episode the individual will be very energetic and sleep much less. They will also have an inflated self-esteem (Hockenbury & Hockenbury 578). This means that the person will be disappointed about their abilities and will make plans for power, fame and wealth. This is one of the reasons why hospitalization is necessary. They can rack up many bills and even disappear for weeks. It's a pretty common disorder. DBSA says it is the sixth leading cause of disability in the world. The direct cause is unknown and cannot be cured, only treated. It happens that there is a risk of inheriting it. If both or one of the parents have it, the risk of having it would increase. There are three different studies that will be reviewed in this article. The first will mainly review the biological effects. The second will look at developmental effects and the third will look at social effects. Heredity appears to play an important role in the onset of bipolar disorder. One study highlighting this biological effect is called “Common Genetic Influences for Schizophrenia and Bipolar Disorder.” The study was conducted by Paul Lichtenstein. The study… half of the article… in the study, I would gather a large amount of both those suffering from bipolar disorder, as well as a large amount of healthy individuals with no known disorders. I would like both groups to be between the ages of 10 and 18. They would be monitored with a fitbit and asked a series of questions once a month for 2 years. They also weighed themselves daily and calculated their body fat percentage once a month. This study aims to find out whether and how drastic the health effects are on those who suffer from bipolar disorder as children. The questions would be asked by a psychologist. I would interpret the data by looking at any type of weight gain, looking at heart rate trends and step trends on the fit side. If you experience large weight gains, lack of steps, or higher heart rates, this could indicate early health problems for children with bipolar disorder.
