In the article, “Selective Serotonin Reuptake Inhibitors And Risk of Suicide: A Systematic Review of Observational Studies” is a research about the link between selective serotonin reuptake inhibitor and the suicide rate. Selective serotonin reuptake inhibitor (SSRI) are class of antidepressant drugs on which many debates and research have taken place over the years and yet now there is no definite conclusion. In this peer-reviewed research, not only SSRI drugs were used, but also other antidepressant drugs were used in the experiment to draw a proper conclusion on if there is a possible relationship between antidepressant drugs and the increasing suicide rate. The experiment were carried by combining the results from independent studies which…

Selective serotonin reuptake inhibitors (SSRIs) remain the mainstay pharmacological treatment for OCD. They are fluoxetine, sertraline, paroxetine, fluvoxamine, citalopram and escitalopram. In this case, Mrs P was taking escitalopram. However, in contrast with depression, SSRIs treatment in OCD requires higher dosage and the response time is somehow longer. Usually, patient with depression respond to SSRIs within 2-6 weeks whereas patients with OCD take 10-12 weeks of response time (Dougherty,…

Currently, there are substantial disagreements within the scientific community regarding the roots of depression. For decades, some psychologists and other professionals have supported the serotonin hypothesis of depression, which proposes that a shortage -or in some instances, an overload- of the chemical neurotransmitter serotonin causes depressive disorder. However, with increased research, along with refined imaging techniques in mood disorders, experts are beginning to reject the chemical…

Serotonin (5-HT) is an important neurotransmitter and paracrine signalling molecule in all bilateral animals, where it mediates gut movements and the animal's perceptions of resource availability. 5-HT was found in the gastrointestinal tract (GI tract), blood platelets, and the central nervous system (CNS) [1] [2]. Approximately 90% of 5-HT in the human body is synthesized and released in the GI tract, and the remainder is synthesized in serotonergic neurons of the CNS. 5-HT is synthesized from…

The neurotransmitter that I chose to research is serotonin. It is created by a biochemical conversion process that combines tryptophan, a part of proteins, with tryptophan hydroxylase, a chemical reactor. Together, they form 5-hydroxyltryptamine (5-HT). Serotonin is manufactured in the brain and the intestines. The majority of the body's serotonin, between 80% to 90%, can be found in the gastrointestinal (GI) tract. It can also be found in the blood platelets and the central nervous system.…

The hormone I chose to research is called Serotonin. It was first discovered by Vittorio Erspamer in Rome in 1935. American scientists then verified all of the findings in the late 1940’s. In 1948, Serotonin was named and isolated by Maurice M. Rapport, Arda Green, and Irvine Page. Serotonin is produced in the Pineal gland in the brain and also in the intestines. Majority of the body’s Serotonin is found, and has a key role, in the gastrointestinal (GI) tract. This hormone is also found in…

GABA and Serotonin are neurotransmitters that help regulate the body’s anxiety level and mood. Brain tests have shown that 15% of normal GABA function and only 25% of normal Serotonin function. You can stimulate your body to produce GABA by eating foods rich in glutamic acid and glutamate. You can also stimulate your body to produce serotonin by eating foods rich in tryptophan. GABA and Serotonin act as gatekeepers in the body. GABA is the chief inhibitory neurotransmitter of the nervous…

How is depression different due to low levels of serotonin vs. noradrenaline? Depression is defined as “a mood disorder that causes a persistent feeling of sadness and lost of interest” (Mayo Clinic). This disorder affects the way you feel, think and behave. Some symptoms of depression include difficulty concentrating and making decisions, feelings of guilt, worthlessness, hopelessness and pessimism, helplessness, irritability, loss of interest in activities once pleasurable such as sex and…

Welcome to the world where Newton’s laws do not exist. Our planet is called Serotonin. In Serotonin, you have the ability to float in mid-air just as if you were floating in space. We are able to float from place to place but not in a fast pace because in our world acceleration does not exist. Everything and everyone is in slow motion, which makes it hard for our citizens to get to places on time. We are able to pick up objects twice our size, it’s actually easier to do construction work on our…

room. Intensify you club experience with 3,4- methylenedioxymethamphetamine (MDMA) or what is better known as ecstasy. Let’s get down to business and talk about the popularity of this drug, along with its destructive nature. Zooming into the brain, neurons release chemical substances that are called neurotransmitters. These chemicals are responsible for daily life and basic bodily functions. Ecstasy primarily targets many parts of the brain that contain the neurotransmitter called serotonin.…
