, causes depression. The antidepressent, reserpine, depletes the monoamines by stopping them from being Depression is a mental disorder characterized by persistent low mood low self-esteem along with a lost of interest in normal pleasurable activities. Not all types of depressions are a mental disorder, a person can be sufering from normal depression, feeling discouraged and hopeless, which might have been brought on by life events, but they get better with time. The normal depression can become unusually severe or prolonged, leading to a unipolar depression. According to DSM-V, feeling depressed, losing interest in life, weight gain/loss, disturbed sleep, fatigue can be all sign of the major depressive disorder as long as the individual has more than five symptoms, has had them for longer than 2 weeks.

Depression can be caused by a host of different factors incuding biological, psychological,sociocultural factors, but today we will look into the biological causes of depression. Starting with the way neurotransmitters travel between neurons, also known as synapse, then looking at the biomedical model of mental heallth and how it applies to depression.

It focuses on the therory that reducing a group of neurotransmitters called monoamines which include serotonin, noradrenalin and dopaminuptaken into the vesicles and they are broken down in cell. Serotonin is broken down by enzymes and the breaken down products can be detected in the cerebrosinal fluid. Levels of serotonin breakdown products appear to be low in individual suffering from severe depression, meaning that there was less serotonin to start with for breakdown, this implies that not enough serotonin was released from the neuron.

    The biological factors those effect on depression including; genes, hormones, and brain chemicals. It is suggested that there is a trait that codes for depression in humans, as depression often runs in families. However, this cannot be confirmed because the prevalence within families could be due to the environment created as results of the disorder. According to findings of Nurnberger and Gershon in 1982, the MZ twins had a concordance rate of %65 (both twins are had depression) while the DZ twins had a concordance rate of 14%. According to Sullivan (2000), the MZ twins were more than twice as likely to develop depression if their co-twin had it than DZ twins.…

    Monoamine Theory Essay

    The knowledge regarding the biological causes of depression is somewhat rudimentary compared to other illness due to the lack of thorough knowledge regarding the complexities of the human brain. However, the monoamine theory, hypothesizes that a predisposition to depression can occur in individuals whose serotonin, norepinephrine, and dopamine have been depleted (Bunney & Davis 1965; Delgado 2000; Hirschfield 2000) Serotonin, norepinephrine, and dopamine are neurotransmitters responsible for regulating mood, focus and motivation by carrying chemical signals from one part of the brain to another, however, in depressed patients, these signals are low or interpreted and hence fail to function effectively. The two pieces of evidence which support the monoamine theory is the effect of reserpine on brain activity and the…

    6) The monoamine theory of depression foresees the underlying pathophysiologic source for depression is the diminution of levels of norepinephrine, serotonin, and dopamine within the central nervous system (National Center for Biotechnology Information). Indication for this hypothesis is sustained with clinical trials and animal testing. Barchas, J., and Altemus, M.

    The use of antidepressant agents address the concern that we need to consider thoughtfully on the relationship between monoamine depletion and depression. Not only the drugs were shown to be effective in other mental disorders, but also there are other problems which are the delay in the onset of the effect (Hirschfeld); no effect on most of the subjects in many studies (Kirsch); and the argument about the serotonin-transporter-linked polymorphic region (Lopez-Leon et al., 2005). Any one of these would challenge the credibility of the monoamine…

    Operant conditioning in this theory is basically rewarding and punishing. For example if a child had done well at school then they would get rewarded for doing so with sticker charts or sweets or even praise. On the other hand if a child has been naughty and done something wrong then they should be punished with maybe a naughty corner etc. This theoretically teaches the child right and wrong. This links to the development of PIES at the infancy stage because of the intellectual, social and emotional development.…

    Possible causes of depressive disorders can be stress, certain life events, and Biological causes. According to research, Biological parents of depressed adoptees have higher incidence of severe depression than do biological parents of non-depressed adoptees. However, many other biological factors can be responsible such as abnormality of 5-HTT gene. This gene is responsible for the brain’s production of serotonin transporters. Likewise, neurotransmitters can play an impact as they maintain mood stability and are very highly correlated with depression.…

    Method Design This experiment was a 3 x 2 mixed factorial design. The first independent variable had 3 levels representing participant training (psychiatry, psychology and no training) x the second independent variable, which had two levels representing conceptualization of depression (biological conceptualization and psychological conceptualization). The dependent variable of the study was participants’ rated likelihood of recovery from depression for affected individuals (described in vignettes), represented by scores on a measurement scale constructed specifically for this experiment.…

    The Lhb In Depression

    • 2 Pages

    The modulatory function of the LHb in depression is intensively investigated by neuroscientists at the moment. The LHb is a structure located ventral in the diencephalon at the stalk of the pineal gland and is thought to be a regulator of monoaminergic brain regions (Geisler et al., 2008). The misregulation of monoamines in the brain is tightly connected to the altered neurotransmission seen in depression, this is known as the monoaminergic theory of depression (Skolnick, 2002). More specifically, 5-HT deficiency may impair antidepressant responses (Sachs et al., 2015). The hyperactivity of the LHb is associated with depression (Wirtshafter et al., 1994).…

    Understanding the biology of major depression is challenging scientific problems with enormous sociological and clinical relevance. In close as it was shown above in the report, Depression is a serious illness that affects mood, thoughts, and behavior, which needs treatment in light of the fact that without treatment it can last for long time. There many medications that control Depression, Fluoxetine is one of them and it works by increasing the levels of plasma norepinephrine, epinephrine and dopamine. And delaying the reuptake of serotonin, resulting in serotonin persisting longer when it is released…

    It often is said that depression results from a chemical imbalance, but the disease is way more complex. Some researchers presume that depression is not solely bought on by a little chemical imbalance, but by factors, such as mood regulations, a stressful life, medication, medical problems and many other things contribute to depression. On the contrary to being depressed there are many pills to be taken to somewhat ease the tension of depression. Antidepressants are often used in the treatment process to somewhat…

    According to recent research “drugs acting on the glutamate system have a more rapid antidepressant effects than conventional treatment” (Sodhi). This information gives researchers a sense of how the brain is affected during its period of depression. It also tells us that antidepressant drugs work stronger than conventional treatments. The research provided to us examines “genes that encode docking ports on a type of nerve cell activated by the excitatory neurotransmitter glutamate” (Sodhi). Depression does not control all of our brain, although it may seem like it, it only occupies the excitatory neurotransmitter glutamate.…
