The protein deposits known as Lewy bodies are believed to damage nerve cells in the brain overtime, causing a loss in cognitive function. Research remains ongoing about Lewy bodies’ specific association with cognitive impairment. Moreover, new research associates the severity of Parkinson’s disease with inflammation in the brain. Inflammation is now possibly linked to the beginning of neurodegeneration. Since inflammation contributes to immune response, the constant presence of immune receptors as a result of chronic inflammation causes dopamine to enter dead cell pathways.
Introduction Multiple sclerosis is an autoimmune disease that majorly affects the brainand the spinal cord (A.D.A.M. Medical Encyclopedia, 1). The disease affects the central nervous system and thus causes limitations of individuals to carry out various activities. In multiple sclerosis, the myelin sheath that covers nerve cell axon is destroyed causing inflammation (MediResource Inc., 1). Destructionof the membrane leads to slowed conveyance of signals from the spinal cord to the brain, which as a result leads to reduced response to different stimuli.
They split into three enzymes. APP uses diverse conduit where the beta-amyloids are created. It then “deposits in the space between neurons and exert toxic effects” (Lu & Bludau, 2011). In certain areas of the brain, amyloids develop into additional abundant with Alzheimer’s. This damages neurons that “react with neuron receptors and axon” (Lu & Bludau, 2011), which impinge the cells ability to function.

This temporarily stabilises the disease’s symptoms. Memantine on the other hand blocks a messenger chemical called glutamate from being produced. This is a chemical which is released in excessive amounts when brain cells get damage, and this damages them further.
If these changes in the organelle functions continue in an altered state, there is a greater risk of affecting the synaptic plasticity. In addition, the “paucity of mitochondria causes the synaptic dysfunction in dendrites and axons” (2). Therefore, synaptic mitochondrial dysfunction is indicative of Alzheimer’s pathogenesis (2). Additional experiments could be performed in order to enhance the relevance and accuracy of the current study. According to the authors, it is necessary to “reveal how the NH2 20-22 kDa tau fragment targets AD mitochondria and if and how it actually impairs the mitochondrial physiology” (2).
Addiction is a very controversial topic. I support the argument that addiction is in fact a disease. Many believe that once you’re addicted it is just a matter of hard work and willpower to overcome it. On a chemical level certain drugs can block receptor sites for neurotransmitters, which will then prompt the brain to create more sites thinking that it needs to make more sites for more neurotransmitters. This will leave a persons brain with too many open unnecessary receptor sites.
Linking Brain and Behavior: Reflections on Neurodegenerative Diseases and Fetal Neural Transplantation Neurodegenerative diseases are caused by malfunctions within the motor sector of the nervous system. These malfunctions, which are caused by the presence or absence of hormones, are a direct result of neural cell deterioration within the brain. Thus, biological problems of the brain, or rather predicaments arising between cellular connections within the brain, and the treatment of such conditions, illustrate how the brain organizes movement and behavior (11). The brain is the body's communication headquarters. It obtains a myriad of information from various parts of the sensory system and processes this information in an organized fashion.
If you are being treated for depression, taking an antidepressant may be part of your treatment plan. Antidepressants work by balancing the chemicals in your brain called neurotransmitters that affect moods and emotions. These depression medicines can improve your mood, help you sleep better, and increase our appetite and concentration. “Antidepressants can help jump start mood and give people the boost they need to get over the symptoms of depression.” Says Eric Endlich, PhD, a clinical psychologist based an Boston. “This often allows them to start doing the things that they enjoy again and make better choices for themselves, which also helps contribute to a more positive mood.” There are many... ... middle of paper ... ...erspective because biosychological is the study of how emotions, thoughts, and behavior are affected by the brain, the nerve system, and neurotransmitter in human and non-human animals.
One of these abnormalities is plaques that clump up, a protein called beta-amyloid which damages and destroys brain cells. In patients with Alzheimer’s the plaques created interfere with cell to cell communication. The other abnormality seen is tangles in the brain. Brain cells depend on an internal support and transport system to carry nutrients and other essential materials throughout their long extensions. This system requires the normal structure and functioning of a protein called tau.
Curcumin Herbal Supplements to Boost Memory There are different factors that may lead to AD such as cerebral deregulation, free radicals, beta amyloid, abnormal inflammation, and also oxidative stress. Curcumin Herbal Supplements help to delay the neural degradation and decrease metal-chelation as well as amyloid plaque. It’s also well known to reduce the formation of microglia. Overall, it helps the memory improvements in Alzheimer patients. Alzheimer is very destructive for the patients’ brains.
