Analyzing Psychological Disorders By Stephanie Marsh-Walker University of Phoenix Schizophrenia is a complex brain disorder. Like many other illnesses‚ schizophrenia is believed to result from a combination of environmental and genetic factors. All the tools of modern science are being used to search for the causes of this disorder. The term schizophrenia is Greek in origin‚ and in the Greek meant "split mind." This is not an accurate medical term. In Western culture

such as delusions and hallucinations‚ examples of these drugs could be chlorpromazine or clozapine. Typical antipsychotic drugs (neuroleptics) work by reducing dopamine within schizophrenia sufferers. Common forms of neuroleptics include drugs such as Thorazine‚ Prolixin and Haldol. These drugs actually block the activity of the dopamine neurotransmitter‚ the drugs take effect within 48 hours but it can be several weeks before a noticeable difference is seen with symptom reduction. Barondes’s (1993)

six million people around the world (“National Parkinson Foundation”‚ 2010) It is a disorder that involves the lack of proper movement in individuals who are suffering Parkinson’s disease. It is a neurodegenerative disorder that induces a lack of dopamine in the neurons of the substantia nigra (Pinel‚ 2008; Dobkin‚ Rubino‚ Allen‚ Friedman‚ Gara‚ Mark‚ & Menza‚ 2012). Some fact about Parkinson’s disease is that it is more prevalent in males than in females (Pinel‚ 2008) and also that the risk

Science Daily — Scientists have found that the pleasurable experience of listening to music releases dopamine‚ a neurotransmitter in the brain important for more tangible pleasures associated with rewards such as food‚ drugs and sex. The new study from The Montreal Neurological Institute and Hospital -- The Neuro at McGill University also reveals that even the anticipation of pleasurable music induces dopamine release [as is the case with food‚ drug‚ and sex cues].

the synapse creating “euphoria” - Ecstasy affects the neurotransmitters of serotonin‚ norepinephrine‚ dopamine‚ & oxytocin. Ecstasy enters neurons through the use of monoamine transporters & then inhibits the transporter; this inhibition INCREASES the levels of activity of neurotransmitters (serotonin‚ norepinephrine‚ & dopamine). Low levels of euphoria feelings are associated with dopamine and serotonin. Increase in oxytocin leads to more trust and decrease in fear 2. What behavioral effects

individuals which have ADHD than those who do not. This anatomical discovery suggests that there is a lack of connectivity between key portions of the brain which control attention‚ stimulus processing and impulsivity. Along with this the neurotransmitters dopamine and norepinephrine are shown to have a part in pathophysiology of ADHD. The neurotransmitter

Presynaptic: On the presynaptic dopaminergic neuron‚ lithium in acute administrations‚ inhibits the release of DA by binding onto the dopamine-specific (D1-D5) autoreceptors (Prasad‚ 2010). These autoreceptors serve as a mechanistic negative feedback loop that controls the release of DA and regulates its levels in the synaptic cleft. Lithium acts as an agonist on these autoreceptors and therefore inhibits the turnover of DA resulting in either increased reuptake or inhibited release from the presynaptic

When there is an overflow the brain stops making it naturally and when the drug wears off it takes time for the brain to star making the chemical once again on its own system. Some neurotransmitters are dopamine‚ serotonin‚ Acetylcholine‚ Norepinephrine‚ Gamm-amniobutyric acid‚ Endorphins. Endorphins are natural opiates.
