It is like a transmitter in the brain and is important for the signals that it sends to the central nervous system and according to the article I found on Functions of Dopamine, “it is what allows information to be passed from one neuron to another”. (Functions of Dopamine, 2018) Some of the functions of dopamine are; motor activity, cognition, emotion, and reward. There are also disorders that are associated with having a low amount of dopamine such as depression and movement disorders. Some of the more serious disorders are schizophreniz, ADHD, OCD, Tourette’s syndrome, and drug abuse. Then if there is a death of dopamine neurons it causes Parkinson’s disease, where a person is robbed of the ability to have smooth and controlled movements.
"One way to understand OCD is that the normal cortical inhibition of the amygdala is malfunctioning and that the anxiety responses induced by the amygdala therefore become more intrusive and chronic in patients with OCD. ?," write Denys, Zohar, and Westenberg in? "The Role of Dopamine in Obsessive-Compulsive Disorder: Preclinical and Clinical Evidence." Dopamine comes into play in response to amygdalae-generated anxiety in that dopamine drives seeking activity. Seeking activity includes not only the search for food, drink and sex but?in times of anxiety and fear?access to safety.
Studies have been made into why childhood trauma affects the adult life of its victim. But now, researchers have begun to reveal what happens in the brain following this kind of trauma. Trauma can cause lasting changes in the areas of the brain that deal with stress, namely the amygdala, hippocampus, and prefrontal
One of the most leading causes of epilepsy is head trauma (most likely from an accident) which is known as “Post Traumatic Epilepsy.” Another cause is brain conditions; when someone has had a stroke or brain tumor in the past they have a higher chance of developing epilepsy. Also, infectious diseases (such as meningitis and AIDS) can cause epilepsy. Lastly, prenatal injuries: mother acquires an infection or oxygen deficiency to the baby and developmental disorders: autism and neurofibromatosis (Epilepsy, 2017). To figure out if someone actually has epilepsy, they will go through tests to be
presence can be identified but it is much more difficult to prove its absence (Gosseries et al., 2011). Causes The vegetative state just like other disorders of consciousness can occur due to three main reasons; the first and most common cause is a traumatic brain injury. As a result of a severe head injury, for example an injury sustained during a car accident, a fall from a great height, or a violent assault, a person can enter into a state of vegetative consciousness. According to Gosseries et al. (2011), in most cases where the damage is severe, patients usually die within a few days.
No matter what your age, you need to ensure that you have a solid understanding of how your own memory operates. Of course, there are some essential developments in the average brain that allows for short-term and long-term memory storage, but memory is also linked into the ways in which we learn because memory is a critical component of retaining information when we
The sympathetic nervous system can respond to stressful situations such as fear, cold, exercise, trauma, and hypoglycemia. The sympathetic division of the autonomic nervous system works by increasing the heart rate and blood pressure by activating the energy that is otherwise stored in the body. The sympathetic division is also known by another popular name which is the fight or flight mode (sympathy-adrenal response) and the reason why they named it this is because when the body experiences stressful situation it triggers sympathetic activation in the adrenal medulla which causes it to release epinephrine and lesser amounts of norepinephrine. These hormones that are released make their way directly into the bloodstream and promote the response that affects the target organ. The sympathetic nervous system acts as an entire unit meaning that it will discharge as a whole
The Biopsychosocial model studies a person on their disorder and how it occurred through biological, psychological, and social factors that could potentially affect them. The biopsychosocial model plays an important role in human functioning in the grouping of illness and disease. The Amygdala influences motivation, emotional control, fear response, and interpretations of nonverbal emotional expressions. Thinking can be improved by activities that require creativity and the use of memory abilities. James-Lange theory of emotion leads to a physiological reaction of labeling an emotion.
An increase in the serum corticosterone levels and a long-term reduction of proliferating cells in the hippocampal formation was reported after environmental noise exposure. (Hirano et al. 2006). Noise causes a significant impairment in the early spatial memory, possibly by disrupting glutamate-NMDA receptor signalling and triggering aberrant tau hyperphosphorylation in the hippocampus. In long-term noise-stress, there is oxidative stress, increased cholinergic activity, reduced dendritic count in the hippocampus and elevated plasma corticosterone level, which can cause impaired spatial memory.
INTRODUCTION This essay will discuss the post traumatic disorder, how it is caused and its treatments, this will be in the application of the case study, so this essay looks at theory and application. Post traumatic stress disorder will be explained and applied to the case study (Kinchin,2009). Post traumatic stress disorder is known as the disorder that is described as being exposed to a traumatic event, of which it involves being intimidated by death or a very serious physical injury, this could be being involved in rape, exposed to natural disasters and experiencing home distractions, during which one will feel helpless, horrified and fearful Kinchin,2009).. After this experiences people tend to be exposed to trauma this trauma will be experienced through memories and having
