Attention Deficit Hyperactivity Disorder. One of the most prevalent mental disorders in children is the Attention Deficit Hyperactivity Disorder or ADHD. Such children's functioning is impaired in multiple settings like the home, school, etc. This is an ailment which if neglected will be carried over into adolescence and adulthood. The symptoms of this disorder are impulsiveness, hyperactivity and lack of concentration. (Attention Deficit Hyperactivity Disorder, 08/24/2005). ADHD involves two sets of symptoms: inattention and a combination of hyperactive and impulsive behaviours. "Most children are more active, distractible and impulsive than adults. And they are more inconsistent, affected by momentary events and dominated by objects in their immediate environment". However, when every function of the child is predominated by such behaviour then it is time to take cognizance. (Barkley, Russell. A, 1998). This disorder was first described by Heinrich Hoffman in 1845. A child with this affliction will either be hyperactive or will seem to be always lost in a brown study. The main causes for this disease are supposed to be neurobiological and genetic. A possible correlation between the use of alcohol and nicotine during pregnancy has been established by various studies. (Stock, Margaret, n.d).
The different drugs used in the treatment of this disease will be discussed in the sequel.
The hormone epinephrine (also known as adrenaline), is released during stressful situations producing an increased heart rate and increased blood flow to the muscles. Stimulants act similarly by increasing the levels of the neurotransmitters dopamine and norepinephrine in the brain. In addition they also act on the limbic system that reward behaviours like sexual intercourse, eating and drinking or in other words actions that are beneficial to the continuation of the species. These are normally accompanied by positive sensations due to increased levels of dopamine in the limbic system.
Stimulants mimic this activity but at a much more enhanced level producing euphoric sensations by directly increasing dopamine levels in the limbic system. Adderall is used to treat children with distractibility, short attention span, hyperactivity, mood swings and impulsiveness. The main ingredients of this drug are Dextroamphetamine Saccharate, Amphetamine Aspartate and Dextroamphetamine Sulfate USP. This drug improves attention span, ability to follow directions, decreases distractibility and impulsivity, stubbornness and aggression. (RxList, 29th January 2005). In most patients tangible benefits are realized within 3 to 4 weeks. The dangers of using this drug are that prolonged use leads to drug dependence and in psychotic children there may be an increase in behavioural disturbance. Further, it is contra indicated in patients with advanced arteriosclerosis, cardiovascular disease, hypertension, hyperthyroidism and a history of drug abuse. (The Medications, Amphetamine Mixed Salts, n.d).
Ritalin or methylphenidate is prescribed for children above 6 years of age suffering from ADHD. Ritalin is the most widely prescribed drug for ADHD. Unfortunately, Ritalin has many side effects and some of these are loss of sleep, loss of appetite, irritability, nervousness, stomach ache, head ache, dryness of the mouth, blurred vision, nausea, dizziness, drowsiness, ticks, hypersensitivity, anorexia, palpitation, etc to name a few of these. (Ritalin Side Effects, n.d.).
The use of stimulants like Adderall, Ritalin has proved to be counter productive because they inspire erratic behaviour as well as produce unpleasant withdrawal symptoms. As these drugs are eliminated by the body, dopamine levels in the brain fall, producing drug craving, depression, and anxiety. In some cases prolonged use creates a tolerance for the drug, requiring larger and larger doses to produce a comparable effect and thus in effect proving to be highly addictive.
Fortunately, the U.S. Food and Drug Administration (FDA) approved Strattera as a medication for ADHD. Strattera is atomoxetine HCL a selective norepinephrine reuptake inhibitor (RxList, 2005). Strattera is not a stimulant and unlike them, which work on dopamine; Strattera or atomoxetine works on the neurotransmitter norepinephrine. Further studies are required in order to contrast Strattera with the stimulants but the evidence already available indicates that over 70 percent of children with ADHD being treated with Strattera have exhibited significant improvement. (Attention Deficit Hyperactivity Disorder, 08/24/2005). This drug might prove to be a panacea for the victims of ADHD.

Forensic Mental Health

In contemporary society, we do have a moral obligation to treat everyone who enters the criminal justice system fairly. However, there are two aspects of this argument that seem to be developing. On the other hand, someone who does not have control of themselves because of mental illness may need to be seen differently than what has been set for "normal" criminals. The literature points in both directions and this can be a difficult call when people are actually entering the system.

In the current literature, the current criminal justice system has specific ideas of what should be done when an individual commits a crime. As an example, Carvan (1999) poses a question in a case study that is pertinent to the shit study. I...

The Interprofessional Practice and the Health Care System

This is also the position Stone (2007) takes in the quote under discussion.
Furthermore, Stone goes on to declare that Australia has been very slow to implement this practice as compared with other countries and government agencies. One of the primary reasons is that the public policy system in Australia is quite complex and the decision-makers have not come into agreement on where to place it in the policy matrix. This leaves Interprofessional Practice and Education in the dark (or the cold) as far as strategic planning for implementation as well as placing itself within the funding cycles of the government disbursements. (Stone, 2007)
Policies are created in order to put in place how politicians and government official...
