There are how many major neurotransmitters that appear to account for most of the effects produced by the action of drugs of abuse on the brain?
There are four major neurotransmitters that appear to account for most of the effects produced by the action of drugs of abuse on the brain. These include dopamine, serotonin, norepinephrine, and GABA. These neurotransmitters play key roles in the reward system, mood regulation, and stress response, contributing to the reinforcing effects of drugs.
How do drugs kill brain cells?
Drugs can interfere with the normal communication processes in the brain by altering the levels of neurotransmitters, disrupting synaptic transmission, and causing oxidative stress. Prolonged drug use can lead to neuronal dysfunction, cell death, and ultimately, the loss of brain cells.
How do nuerotransmitters get poison?
Neurotransmitters can be affected by toxins or chemicals that inhibit their release, uptake, or receptor binding. For example, substances like pesticides, heavy metals, or drugs can disrupt the normal functioning of neurotransmitters by interfering with their synthesis or signaling pathways. This disruption can lead to toxic effects on the nervous system and affect brain function.
What is pharmacodynamics?
Pharmacodynamics is the study of the biochemical and physiological effects of drugs on the body or on microorganisms or parasites within or on the body and the mechanisms of drug action and the relationship between drug concentration and effect.
Why are receptors so important in understanding the effects of drug abuse?
because certain drugs affect certain neurotransmitters. the major groups of neurotransmitters affected by the most abused recreational drugs are gaba, dopamine, seroatonin, and nor epinephrine. Granted within each group there are hundreds of subtypes of neurotransmitters (i.e. 5HT1, 5HT2, etc... in the serotonin category). Also, in the opioid category there is theta, kappa, and mu. Also, some drugs work by stimulating ur brain to make more of a certain neurotransmitter, while others block the receptor cite so one's natural output of neurotransmitters collect bc they have no where to go. for example alcohol, benzos (xanax, klonopin, ativan, lorazepam, temazepam, valium), and GHB (one of the "date rape" drugs all affect Gaba. Alcohol and benzo addicts can actually die and have seizures if they suddenly quit cold turkey without tapering. also, opiate addicts, who quit, will usually experience PAWS - post acute withdrawal symptoms, in the form of depression, not in the boo-hoo crying type, but rather the lack of motivation, I don't care to move or do anything type of depression, which is from a lack of dopamine. therefore, when addiction psychiatrists prescribe SSRI antidepressants, it is usually illogical since the depression is from a lack of dopamine and not serotonin. (a simple example) .
How do drugs affect the process of synaptic transmission?
They can act in a number of ways, both presynaptically and postsynaptically. They can affect how vescicles release neurotransmitters, how neurotransmitters are cleaved/reuptake, they can block receptors, destroy receptors, agonistically bind to receptors which mimics the neurotransmitter. These are a few.
Using drugs changes the brain due to the unnatural flood of neurotransmitters For example may make less?
Using drugs causes an abnormal release of neurotransmitters in the brain, which can disrupt the normal communication between brain cells. Over time, this can lead to changes in the brain's structure and function, often resulting in decreased natural production of neurotransmitters.
What is the effect of excitatory psychoactive drugs on the brain?
Excitatory psychoactive drugs such as nicotine and cocaine primarily affect the central nervous system. They increase post-synaptic transmissions and may result in addictions and substance abuse. These stimulants increase the alertness of the user by mimicking the action of neurotransmitters or delaying the breakdown of neurotransmitters. They can also affect the transmission of optical signals in the thalamus of the brain.
Most psychoactive drugs produce their effects primarily by acting on?
neurotransmitters
How do you stop neurotransmitters getting influenced by drugs?
Will power is all it takes. Simple as that.
What type of drugs block the effects of certain neurotransmitters on the brain?
Anti-psychotic
What are two ways the drugs affect the brain chemistry?
increases and decreases the amount of neurotransmitters
How could the drugs effect the nervous system?
nerves drugs increase or decrease or block chemical neurotransmitters effects according by physician diagnose
How does social study relate to population family for life drugs and aids?
What is the relationship between social studies, and population, family, drugs and Aids.

How does drugs affect relationship between parent and child?
That's interpretive. Some drugs users lead very normal lives with no one knowing they are.
What is the relationship between drugs and tremor?
Several different classes of drugs can cause tremor as a side effect. These drugs include amphetamines, antidepressant drugs, antipsychotic drugs, caffeine, and lithium. Tremor also may be a sign of withdrawal from alcohol or street drugs.
