The Neurobiological Factors Associated with Depression
Depression is a mood disorder that affects approximately ten percent of men and nearly twenty-five percent of women at least once in their lifetime (1). There are several types of clinical depression, such as unipolar depression and bipolar depression. Unipolar depression consists of primarily depressive states while bipolar depression involves a fluctuation between states of depression and mania (2). Some of the most common symptoms of depression include excessive feelings of sadness, guilt, or worthlessness, a significant change in appetite, insomnia or hypersomnia, energy loss, thoughts or attempts of suicide, and anhedonia (3), (4). While the symptoms of depression are understood fairly well, how the exact causes of the disorder interact in the development of depression remain somewhat of a mystery.
There are several biological factors that may contribute to the increased susceptibility to depression. Genetic links have been made as the result of twin studies suggesting that family members of depressed patients are more likely to be depressed or to develop depression than the general population. However, it is important to note that these results may be due to the similar environments of twins rather than genetic influence (5). Consequently, studies comparing twins who were reared apart have been conducted and the data suggest that the concordance rates for twins reared together or apart is nearly identical, although the rate is slightly lower for twins reared apart. This suggests that while the environment does play an important role in the development of depressive symptoms, genetic influences are also important (6). In addition, other genetic studies have sugges...

Puritans believed in strict religious dedications, by trying to follow the holy commandment. “The discipline of the family, in those days, was of a far more rigid kind than now.”(Hawthorne 9). They wanted to be considered the holiest of all people because they try to reflect a world of perfection in the sight of God. While they where trying to portray a holy life; however, they where also living a sinful life because they have been judgmental, slandering, uncompassionate, resentment, and forbearing, which are all sinful acts of the bible.
In unit seven, this learner took part in a debate involving the causes of depression. Depression is a debilitating mental disorder that can be detrimental to a person’s way of living. For centuries, psychologists and researchers have been searching for a single cause of depression, identifying two perspectives to date. The cognitive-behavioral perspective includes influences of faulty thinking that develops from low self-esteem and or a learned helplessness. In addition, cognitive-behavioral perspective indicates environmental influences such as poor living conditions and socioeconomic issues as causes of depression. However, this learner presented evidence along with personal experiences to support the biological perspective of the debate.
Depressive disorders take on different forms. There are three common types of depressive disorders. They are major depression, dysthymia, and bipolar disorder. Major depression is characterized by a combination of symptoms that interfere with an individual's ability to work, study, sleep, and eat. Symptoms include but are not limited to the following: persistent sad, anxious, or empty mood, feelings of hopelessness, feelings of guilt, helplessness, worthlessness, decreased energy, fatigue, appetite and/or weight loss, or overeating and weight gain, ...
This paper will have two sections: The first section will be a brief explanation on what is depression. In addition, what is the percentage of depress people in the United States. Furthermore, it will discuss in details several theories that are best suited to treat depression disorder. Moreover, the theories that will be briefly discussed are as follows: Cognitive Therapy (CT), Cognitive Behavioral Therapy (CBT), and Interpersonal Therapy (IPT). The second section will be a summary of a counseling session the learner had with a client and the treatment that was given to help alleviate and ceased the depression from reoccurring.
Many twin studies have also shown results that genetically identical twins (MZ) have a greater number of inheriting depression than non-identical twins (DZ). For instance an experiment carried out by Prince in 1968 expected that MZ twins would have a higher concordance for depression compared to DZ twins. Results found were that the MZ twins who were raised in the same environment/family showed a concordance of 68% and DZ twins had a lower concordance of 28% for bipolar disorder only. This is evidenc...
It is commonly accepted that an estoppel is a legal doctrine which prevents a person from negating or claiming a fact due to that person’s prior conduct. The doctrine of estoppel has been applied for years and different forms of estoppel have been established. For the purpose of this essay, I will predominantly concentrate on promissory estoppel in relation to the law of contracts. This essay will be approached by discussing the issues of pre-contractual liability, consideration, reliance and the doctrine as a cause of action or defence and a slight comparison of the standpoints that various jurisdictions hold towards these issues. These arguments would conclude the uncertainty of the doctrine and thus, the difficulty and issues that would be faced with the codification of the estoppel.
Having evaluated the current state of English contract law, mainly made up of piecemeal solutions, it can be seen that despite being satisfactory and doing its job, there still remain gaps within the law of contract where unfairness is not dealt with. Moreover, due to the ad hoc nature of those piecemeal solutions, the latter have often produced inconsistent justice and have manifested cases of unfairness. Hence, “a relatively small number of respected Justices have endeavored to draw attention to the fact that the application of a general principle might be useful and even necessary in English law.”
Depression is one of the most widespread mental disorders globally, affecting more that 350 million people of all ages. It is characterized by disturbed sleep, loss of appetite, sadness, poor concentration and feelings of guilt. There are various types of depression which are long lasting, and other types which are constantly reoccurring (World Health Organisation , 2012). Severe symptoms of depression that inhibit the ability to work, sleep and eat is categorised as major depression, this form of depression can occur once in a lifetime, however in some circumstances it may occur more often. Persistent depressive disorder can last up to 2 years; symptoms may resemble major depression along with episodes of less severe symptoms. Psychotic depression is a form of severe depression when a person begins to hallucinate and have delusions. Postpartum depression is experienced by women after birth, physical and hormonal changes can lead to depression. Seasonal affective depression (SAD) usually occurs during winter due to less sunlight. Another major type of depression is bipolar disorder which is categorized as changes in mood, for instance extreme high moods to extreme low moods (National Institute of Mental Health, 2011). The prevalence of depression was analysed in 8449 individuals aged between 15 and 40, results showed that depression was commonly found in white males and females than in black and Mexican male and females (Stephanie et al, 2005).
Depression is much more common than most people think. Because it is essentially an invisible illness and is largely in the mind, it is difficult to correctly diagnose it and most people suffer for months, years, or even decades with depression. The Merriam-Webster Dictionary defines depression as “a mood disorder marked especially by sadness, inactivity, difficulty with thinking and concentration, a significant increase or decrease in appetite and time spent sleeping, feelings of dejection and hopelessness, and sometimes suicidal thoughts or an attempt to commit suicide.” Most medical definitions are able to explain what happens and why it does, but after carefully examining this one, we only notice that it explains what happens, but not why. Usually, the symptoms of an illness are...
We as a society need to all take responsibility when we are on the road and avoid the many temptations and distractions surrounding us. Distracted driving is dangerous plain and simple. Some may be willing to take the risk because they have never had an accident while behind the wheel. But it’s
A fire investigator will first ensure that the fire did not have an accidental cause, by searching for clues like faulty wiring, cigarette smoking and overheated electric motors. Then the investigator will begin an extensive on-site investigation by first looking for containers that are capable of holding an accelerant, as well as an ignition device such as a candle. The investigator will also looking for irregularly shaped patterns on the floor, which would be caused by the accelerant. Finally, the accelerant will search for signs of breaking and entering and theft.
...e to seek to find something in their lives to keep them alive. Having someone to depend on is necessary for an individual to succeed in life. They provide each other with motivation, love, and simply the will to live. In a world where everyone is only out for themselves, it is important to establish a symbiotic relationship with a loved one in order to survive. External threats will always exist in the society we live in, however it is up to an individual to grasp some sort of motive to make life worth living for.
In Krell v. Henry {1903} a plea of frustration succeeded because the court held that the common purpose for which the contact was entered into, could no longer be carried out. But in the same year for similar set of facts, the Court of Appeal decided in Herne Bay v. Hutton [1903] that the contract had not been frustrated because the "common formation of the contract" had not changed. It clearly was a policy decision which shows the reluctance of the courts to provide an escape route for a party for whom the contract ha...
In English Law consideration is one of the three main areas of an enforceable contract. It may be defined as an act, forbearance or promise made by a single party that constitutes the price for which the promise of another, is bought. In simple terms, the basic understanding of consideration may be seen as a ‘give and take’ tactic between two parties.
