In our brains we have two major areas that are responsible for controlling our movements, these areas are the substantia nigra pars compacta and the basal ganglia. The substantia nigra pars compacta is responsible for producing dopamine, which controls the transmission of messages that initiate and control movement and balance. The basal ganglion is composed of numerous subcortical nuclei, which are crucial for controlling fine motor movements. Unfortunately, these areas of the brain are majorly impacted on people with Parkinson’s disease. These individuals are commonly between the ages of 50 to 65 years old and are estimated to live to about 75 years old. Parkinson’s disease is a slowly progressive, incurable neurodegenerative disorders …show more content…
Also, they also have the option to have a surgical procedure that can be done, however, only certain patient can be qualified based on their age and health conditions. The most effective medications prescribed to patient are Levodopa, dopa¬mine agonists, COMT inhibitors, and MAO-B inhibitors. Levodopa and dopa¬mine agonists are most common used medications for patients withs Parkinson’s disease. Levodopa is typically combined with carbidopa, together the both convert into dopamine in order to replace the dopamine that has been lost. Dopamine agonists acts a form of dopamine in order to stimulate never cells. COMT inhibitors and MAO-B inhibitors are used to block any enzymes that break down …show more content…
Neural transplants surgery is completed by placing a placing a fetal donor dopamine producing cells in the basal ganglia. Deep brain stimulation surgery implant a stimulator and electrodes inside the brain. Once the implant is completed, the stimulator and electrodes work cohesively together in order targets the sub-thalamic nucleus or the globus pallidus interna in the thalamus. Sub-thalamic nucleus DBS increase speed of movement, rigidity gait, postural stability, and decrease dosage use of medications. However, it is only effective for patients who are young and healthy. Globus pallidus interna DBS decease dyskinesia and is only appropriate for older patients. Other forms of surgery that can be done are thalamus and pallidotomy surgery, which destroy a small area of the thalamus or globus pallidus to control tremor or

    The basal ganglia (BG) receives input at the striatum from the cortex and provides output from the pallidum, in particular the globus pallidus internal (GPi) via the ventral anterior and lateral (VA/VL) thalamic nuclei to the cortex – forming a motor loop.1,2 There are two major pathways in this motor loop, the direct and indirect pathways.1,2 The direct pathway originates in the cortex, projecting to the striatum of the BG which consists of the caudate and putamen nuclei.1,2 The striatum projects to and inhibits the GPi which has tonic inhibitory connections to the VA/VL nuclei of the thalamus and finally back to the motor and premotor cortex.1 Activation of the direct pathway initiates voluntary movement, by releasing upper motor neurons in the cortex from inhibition.1,2 The globus pallidus, internal and…

    Lewy Body Dementia Its Christmas, the air is cold as you step out of your car. You hurriedly grab your coat, and several bags and the pumpkin pie. You walk up the sidewalk you played on as a child. It has been several months since you have been here, and you notice several small changes. There is no holiday wreath on the door, and the welcome mat is the Welcome Spring mat.…

    In the past it was believed that the cerebellum received information from various areas of the cortex and projected information to the primary motor cortex via thalamus, thus fine-tuning a movement (19). It was also believed that the Basal ganglia was involved with the inhibition and selection of action commands (19). These views suggest the involvement of both cerebellum and Basal ganglia(BG) in purely motor function. But that is not the case, recent studies have found a connection between the BG and cerebellum and projections from these areas to the cortex through the thalamus. Premotor, prefrontal, temporal and parietal cortices are the areas that receive projections from the BG and the cerebellum implicating its involvement in non-motor…

    The choroidal arteries are deep cerebral arteries that supply deep structures in the brain. The anterior choroidal artery is a branch of the internal carotid and it supplies the choroid plexus in the lateral ventricles, parts of the visual pathway, the putamen, the thalamus, and the hippocampus. The posterior choroidal artery is a branch of the posterior cerebral artery. It supplies blood to the choroid plexus of the third ventricle and parts of the thalamus and hippocampus.…

    Side effects and symptoms of dopamine agonist medications can be presently seen in a person within six weeks of taking the medication (Drugs 2). The drug Levodopa is thought to be the most effective drug for controlling the symptoms of Parkinson’s disease, but Levodopa has not been shown to slow disease progression. Taking this medication is supposed to delay the symptoms of PD, but it could even make it worse. Additionally, the drug has significant abnormal side effects for some patients such as dyskinesia, which is an abnormal impairment of voluntary movement (Drugs 2).…

    In the hypothalamus, there is a neural circuit known as the melanocortin system, which includes two populations of neuron located in the arcuate nucleus, that express the proopiomelanocortin propeptide (POMC) and agouti-related protein (AgRP) (Roseberry, Stuhrman et al. 2015). POMC propeptide is the precursor to the melanocyte-stimulating hormones (α, β, and γ-MSH) (Roseberry, Stuhrman et al. 2015). The melanocortin system plays a significant role in controlling feeding and body weight (Roseberry, Stuhrman et al. 2015).…

    Parkinson’s Disease (PD) is a progressive neurological condition of which there is currently no cure. The main pathological feature of the disease is degeneration of the dopaminergic neurons within the brain, primarily in the Pars Compacta region of the Substantia Nigra (SN). This is thought to be a result of the formation of soluble aggregates of α-synuclein known as ‘Lewy Bodies’ in the neurones of PD patients, which can be clearly seen in various regions of the brain upon post mortem examination. Lewy Bodies are a rather obscure area of research and it is not known whether they are the direct cause of neuronal death. However, several studies have proven that Lewy Bodies have the ability to spread from cell to cell and propagate to other parts of the body: when ventral tissue from the fetal midbrain is transplanted into the SN of PD patients, Lewy Bodies can be found in the new tissue after several years (REFERENCE); and perhaps more significantly, it was recently discovered by Lee et al., that after injection of brain lysate containing Lewy Bodies into the stomach wall of mice, α-synuclein spreads from the stomach wall into the myenteric neurons of the enteric nervous system.…

    C. According to Harvard Health the medications used to treat Parkinson’s either increase the level of the patient’s dopamine or imitate the effect that dopamine has on the body (Harvard Health). D. If the patient fails to respond to the medication other options such as deep brain stimulation and destroying small areas of the brain might also be considered (Harvard…

    Last there is the brain. The brain is the control focal point of the human body. The human brain stores data, corresponding that data with other data to offer the body some assistance with making selections and to have the body put the decisions into actions. The brain and spinal cord are created from the neural tube. The neural tube then extends causing the tube to then makes three locales called the primary brain vesicles: prosencephalon, mesencephalon, and the rhombencephalon.…

    Huntington’s disease (HD) is one of many neurological conditions that exist and is prevalent in about 7 people per 100,000 (Lundy-Ekman, 2013, p. 245). It is more commonly seen areas of a predominantly white population, such as Europe, North America, as well as Australia, due to a higher frequency of certain alleles that are repeated in these populations (Walker, 2007, p. 221). This disease is classified as a neurodegenerative disorder, which is a term that is used to describe CNS disorders/diseases that are progressive (Damjanov, 2012, p. 465). These disorders typically present many different neurologic and psychiatric symptoms, such as “abnormal body movements and progressive mental deterioration”, and it is also possible to have either…

    Parkinson's disease Definition: Parkinson’s disease is a progressive disease of the nervous system marked by tremor, muscular rigidity, and slow, imprecise movement, chiefly affecting middle-aged and elderly people. It is associated with degeneration of the basal ganglia of the brain and a deficiency of the neurotransmitter dopamine. Causes: Nerve cells use a brain chemical called dopamine to help control muscle movement. With Parkinson’s disease, the brain cells located in the substantia nigra that make dopamine become impaired or die. Researchers do not know the cause of the death of the cells in the substantia nigra however.…

    Generally, the treatment of Parkinson’s involves exercise, good nutrition and physical therapy. Physical therapy will help with a patient’s everyday motor function. The therapist will often work on balance and reduction of freezes due to stiff muscles. A good diet is important because of depression and slow muscle movement. Depression is often a common side effect of Parkinson’s, so therefore a person may lose interest in eating good food.…
