Parkinson’s disease (PD) is a neurodegenerative disease which is progressive, incurable and debilitating. The disease is caused by a loss of dopamine producing neurons in the brainstem which leads primarily to motor deficits. In Australia, 1 in 350 people live with PD and the prevalence is quickly growing (Parkinson 's Queensland, 2014). While most of the people diagnosed with PD are over 65 years old, people as young as 30 can develop the condition (Parkinson 's Queensland, 2014). Currently, there

National Alliance on Mental Illness says that there are many dissociative disorders some are dissociative amnesia, dissociative fugue, depersonalization disorder and dissociative identity disorder that was called multiple personality disorder (NAMI, 2016). This paper will look at dissociative identity disorder and what brain abnormalities occur. According to Mayo Clinic, dissociative identity disorder (DID) is written off as the swapping of alternate identities in one person. The person may feel

so administration for models is a vital step in order to produce Parkinsons symptoms. The preferred locations in the brain for injection are the substania nigra, striatum or the medial forebrain which is a common root for rat models, these locations reflect the motor defifcts associated with parkjinsons by dopamine depletion in the striatum and destruction of the dopaminergic neurons (Blum et al., 2001). What makes this neurotoxin more benifical is that it has been found to be a endogenous neurotoxin

Throughout the article, the author discusses how adolescents are more likely to take risks than children or adults due to the brain. It’s not that teens don’t understand the consequences to their wild decisions, it’s just something teens tend to ignore while making them. Laurence Steinberg, a social neuroscientist quotes “Posit teens are more likely to indulge in risky business because of the way their brains are maturing.” Dramatic changes start to happen in our brains right around the start of

(Carson, 2012). The most common treatment for ADHD is methlyphenidate, or Ritalin, a dopamine agonist/ norepinephrine agonist that inhibits reuptake of the neurotransmitter dopamine and norpinephrine. Methlyphenidate increases dopamine in the dorsal striatum, and both dopamine and norepinephrine in the prefrontal cortex. Notwithstanding, the fact that MPH is a dopamine agonist suggest that this disorder may be

MDD is prevalent in about 7% of people in the United States with many different reasons for occurring (American Psychiatric Association, 2013). Some causes include personality, environment, genetics, and other disorders (American Psychiatric Association, 2013). About 60-70% of people with MDD will improve with standard medication and therapy, but 30% will not respond (Serafini et. al, 2015). These people who do not respond have treatment-resistant depression (TRD). TRD is characterized by an inability

misfolded proteins resulting in the lewy bodies. The neurons of the substantia nigra are thought to make up the nigrostriatal pathway, thus their destruction would result in loss of dopamine up to the striatum, made up of the caudate nucleus and putamen. This loss of sufficient dopamine to the striatum of the basal ganglia is what is causing most of the motor movement symptoms seen in PD patients (Dauer). My grandpa used to be a police officer, and I have always perceived him as this big tough guy

Parkinson’s Disease and Action of Drugs on Movement Introduction: Parkinson’s disease is a neurological disorder that seriously impairs motor function, with people afflicted with this condition exhibiting akinesia, muscle rigidity and having a tremor at rest. It is accepted that the loss of motor function is brought upon by the progressive degeneration of nigrostriatal dopamine neurons, which leads to a corresponding loss of dopamine in the caudate/putamen part of

Over 70% of adolescent deaths each year are caused by risk-taking behaviors, such as reckless driving. Even though parents allow their adolescent to be more independent, adolescents tend to engage in more maladaptive, risky behaviors when unsupervised. Due to the immaturity of their prefrontal cortex, adolescents may not yet have the cognitive resources to effectively avoid risky behaviors and so parents may play an important role, helping their children to regulate their behaviors and engage in

Thus far we have been looking at healthy individuals regarding sexual motivation and sexual behavior. However, there are also studies that specifically look at individuals with compulsive sexual behaviors. Compulsive sexual behavior (CSB) or hypersexuality has been difficult to define. There are those that would measure it purely based on the number of orgasms an individual achieves in a specified time frame, but as Bradford (2001) stated there needs to also be an interference with the individual’s
