Adepressive disorder, also known as depression, is a mentalcomplication in which victims exhibit low moods across differentsituations, lasting for more than two weeks. Victims with depressivedisorders have the tendency of exhibiting low self-esteem, lowenergy, and pain lacking obvious causes, and loss of interest inperceived enjoyable activities. In some cases, a victim can alsoexhibit false beliefs, or even hear or see things that other peoplearound them are unable to see. Some individuals experience extendedperiods of depression, which fall and rise over time, while othershave all these conditions all their time. The depressive disordershave far-reaching implications on the social wellbeing of anindividual, including affecting individuals’ work life, familyrelations, eating and general health negatively. Moreover, peoplesuffering from depressive disorders are at high risk of committingsuicide. According to Richards,Steven, and O`Hara (2014),as significant as 7 percent of the individuals who die by suicidesuffer from the depressive disorder, while 60 percent of those whocommit suicide as a result of depressive disorders also tend to havesuffered from other forms of mood disorder.
Accordingto Lynchand Barber (2010), severalexplanations to the causes of depressive disorders exist,biopsychosocial models and diathesis–stress model are the mostpopular accounts. Based on the biopsychosocial models, depressivedisorders could be due to various factors, including biological,social, and psychological factors. Based on the diathesis–stressmodel, the depressive disorder occurs when diathesis or existentvulnerabilities are activated by stressing experiences. In this case,the pre-existing vulnerability could arise in the form of geneticfactors, nurture, or interactions between nurture and nature.Besides, depression may also occur because of damages of cerebellumincapacitates cognitive coordination.
Thestatistics on the prevalence of depressive disorders are documentedand mostly reveal a significant fraction of the global population isaffected by the problem. According to Gilbody,House and Sheldon (2015),for instance, as great as 3.6 percent (270 million) of the globalpopulation is affected by major depressive disorders. The percentagesof people who are affected by depressive disorder at one time oftheir life are also high, but they vary across regions, for instance,it is about 7 percent in China and 21 percent in France. According toFournier,DeRubeis and Hollon et al. (2012),the lifetime prevalence of depressive disorder tends to be higheramong populations in developed countries (16 percent) than developingcountries (11 percent). As far as the most year lived disabilitiesare concerned, depressive disorders come second after back injuries.In many cases, the mental complications set in when individuals reachthe 20s and the 30s.
Peopleare experiencing a depressive disorder often have low mood thataffects all aspects of life, including the inability to enjoyexperiences that the individuals once found to be pleasurable.Depressive people may also be engrossed with feelings or thoughts ofworthlessness, self-hatred, regrets and inappropriate regrets aboutlife. Under harsh circumstances, victims of the depressive disordermay exhibit the symptoms of psychosis. The unusual symptoms includedelusions and hallucinations. Other typical symptoms associated withthe mental conditions are poor memory and loss of concentration,irritability, suicide ideation, withdrawal from social activities andreduction in the sex life. The victims have also been observed tosuffer from insomnia, with many often waking up early and cannotsleep, although the use of antidepressants could also cause insomniabecause of their stimulating effects (Driessen& Hollon, 2010).
The DSM-IV criterion provides perhaps the most standard procedure for diagnosing major depressive disorder. For a person to be considered to suffer from a depressive disorder, he or she needs to exhibit the follow behavioral characteristics.
Reduced interests in activities that the victims found pleasurable
Depressed or irritable mood for the most part of the day, which also tends to be repeated daily Change in weight by about 5 percent, as well as change in appetite
Hypersomnia or insomnia
psychomotor retardation or agitation
Suicide thoughts (American Psychiatric Association, 2013)
Threetreatment modalities are available for management of the depressivedisorders. These modalities are medication, psychotherapy, andelectroconvulsive therapy (Braun,Bschor, Franklin & Baethge, 2016).However, there are various suggestions of patterns that have beenlauded to be useful such as transcranial magnetic stimulation (TMS)and exercise. Psychotherapy is the preferred to medication forvictims under the age of 18.
Accordingto Patton(2015), antidepressant drugsshould only be applied for initial treatment of more or less milddepression. This view is based on the rationale that risk-benefitratio of medications is often poor. The guidelines recommend that ifantidepressants and psychosocial interventions should be combined,they should only be done under a set of four circumstances:
When victims have a history of moderate and severe depression,
For victims with mild depression that has existed for long,
As a first line intervention for victims with present moderate to severe responses and
As a second line intervention for mild depression that persists after all other interventions have been exploited (Kirsch, Deacon & Huedo-Medina et al. 2013).
Thestandard guidelines also recommend that the use of antidepressantsshould be persistently for six consecutive months to avoid cases ofrelapse and that the use SSRI should be preferred to tricyclicantidepressants.
Accordingto Siu(2016), the treatment guidelinesfor the victims with depressive disorders should be tailored towardseliminating the dysfunctional behavioral attributes that the victimsexhibit, and should consider factors such as severity of thesymptoms, other preexisting disorders and the preferences of thepatients and prior experiences that victims may have concerning thetreatment.
Inconclusion, a depressive disorder, also known as depression, is amental complication in which victims exhibit low moods across allaspects of life. Victims with depressive disorders have the tendencyof exhibiting low self-esteem, low energy, and pain lacking clearcauses, and loss in interest in perceived enjoyable activities. Insome cases, a victim can also exhibit false beliefs, or even hear orsee things that other people around them are unable to see. Someindividuals experience long periods of depression, which fall andrise over time, while others have all these conditions all theirtime. Depressive disorders could be caused by biological, social, andpsychological factors.Threetreatment modalities are available for management of the depressivedisorders. These modalities are medication, psychotherapy, andelectroconvulsive therapy. However, there are various suggestions ofmodalities that have been lauded to be effective such as transcranialmagnetic stimulation (TMS) and exercise.
