Lysergic Acid Diethylamide (LSD) LSD)‚ a potent hallucinogenic drug‚ also called a psychedelic‚ first synthesized from lysergic acid in Switzerland in l038. Lysergic acid is a white odorless drug‚ a component of the mold of ERGOT. Ergot is a product of the fungus Claviceps purpurea. Th e bio-active ingredients of ergot are all derivatives of lysergic acid. LSD is a semi-synthetic derivative of lysergic acid. Thus LSD is an "ergot" - like substance. The drug evokes dreamlike changes

dopamine‚ cholecystokinin‚ acetylcholine‚ GABA‚ substance P‚ and serotonin itself. They have been demonstrated to be involved in sensory transmission‚ regulation of autonomic functions‚ integration of the vomiting reflex‚ pain processing and control of anxiety. While the physiologic functions of the 5-HT3 receptor are discrete and difficult to detect‚ it plays a key role in certain pathologic situations related to increased serotonin release. Clinical development of 5-HT3 receptor antagonists revealed

Presentation Questions Ecstasy 1. Explain how the brain normally regulates serotonin. How does ecstasy act in the brain‚ & what neurotransmitters does it affect? - Normally‚ the brain regulates serotonin (5-HT) by taking up the release in neighboring neurons. - With ecstasy‚ the neuron is still supplied with 5-HT directly. However‚ ecstasy MIMICS 5-HT by blocking the reuptake of serotonin‚ [causing the release of high levels of 5-HT into the synapse]‚ which induces euphoria & the

EXPLANATION - Neurotransmitters -Serotonin Disturbances in the levels of the neurotransmitter serotonin appear to be a characteristic of individuals with eating disorders. Kaye 2005 found a reduction in the levels of the serotonin metabolite 5-HIAA in people with eating disorders. This suggests that brain serotonin pathways are underactive. Using PET scans it has been shown that there are fewer serotonin receptors in the brains of those with eating disorders. The brain serotonin system has been implicated

A nurse is caring for a client who states that he has abused his son because of the stress caused by his son’s mental illness. How should the nurse use the communication tool of ’clarifying’ when speaking with this client? The nurse needs additional information/ validation so w/ appropriate questioning the nurse should be able to get more clear/ detailed information of what client means What are the legal rights of a person admitted to an inpatient mental health facility?

monoamine transporter (VMAT). This transporter normally transports dopamine (DA)‚ 5-HT (serotonin)‚ and norepinephrine (NE) from the cytoplasm to the vesicle in the presynaptic neuron. Because these neurotransmitters are not packaged‚ they are degraded quickly by monoamine oxidases (MAOs). 4. Inhibition of synthesis of the neurotransmitter. Drug: p-chlorophenylalanine (PCPA) Pharmacology: Indirect serotonin antagonist. Primarily used in research. Mode of action: PCPA

The biological approach asserts that something in our biology is the fundamental cause of dysfunctional behaviour which could be a genetic cause or a malfunction of brain structures. Although it is seen as the most common explanation for schizophrenia due to the use of drug therapy‚ it would be deterministic and reductionist to explain schizophrenia only with the biological approach since there are other numerous factors such as the ones related to the cognitive explanation or other environmental

severe. The user will swear off the drug after crashing. Some users will even seek help from medical professionals and be prescribed medications. The second drug abuse pattern us where the user “makes peace” with the drug. They accept the suppressed serotonin by using large doses of MDMA. It ends up becoming more like methamphetamine than ecstasy. The fate of the users is not well known in this pattern as it is rarely and abuse pattern. Although‚ most users end up crashing and seeking help. The escalating

has a physical or organic cause. One explanation suggests that some people are simply more genetically inclined to develop depression‚ as Hecimovic suggested that it was caused by a mutation in the 5-HTT gene‚ which was responsible for coding for serotonin production‚ and that this mutation is inherited. Family studies‚ twin studies and adoption studies have all helped support the role of genetics in the development of depression. Gershon found that if a parent of a child had depression ‚ that the
