This Week Five Assignment will focus on the components of the neuroscience aspects topic of the Post-traumatic Stress Disorder (PTSD). I will include the causes of it which is the theories of etiology. I will also review how the factors develops it’s genetic, environmental, familial or lifestyle. I will analyze the pathology, including genetics and biochemical aspects. Then, having to diagnose the research technologies on PSTD. Thesis: Having to analyze neuropsychological disorder, including…

Our interest in the topic of Down syndrome (Trisomy 21) started when we heard about how many people are affected by this disease. The number of people affected by this disease in the United States alone is around 400,000 people. This genetic disorder is caused when a person is born with an extra copy of chromosome twenty-one. Down syndrome is recognized by things such as short stature, a distinctive palm crease, stubby fingers, mental retardation that can end up being serious, a wide gap between…

Chapter Two Literature Review 2.1 Multiple Sclerosis Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system (CNS) that remains incurable. The disease manifests as a wide range of neurological deficits including cognitive impairment, impaired coordination, visual disturbances, and extremity numbness (Weinshenker et al., 1989). MS affects approximately 400,000 people in the US and 2.5 million worldwide and it is the most common inflammatory neurological disease…

Multiple sclerosis, also known as MS, is an immune-mediated progression in which an atypical reaction of the body’s immune system is charged against the central nervous system (The National Multiple Sclerosis Society). The central nervous system includes the brain, spinal cord and optic nerves. The antigen — or object the immune cells are triggered to attack — remains unidentified, which is why MS is regarded by many specialist to be "immune-mediated" instead of "autoimmune." The immune system…

Virchow-Robin (VR) spaces or perivascular spaces of the brain refer to spaces that accompany the cerebral vessels as they pass from subarachnoid space into the brain parenchyma. A few evident perivascular spaces can be considered normal at any age but many visible perivascular spaces are not. The relevance of visible perivascular spaces to SVD is shown by their presence in increased numbers in patients with white matter hyper-intensities and with symptomatic lacunar ischemic stroke. The…

Alzheimer's Disease (AD) is neurodegenerative disease that affects patient's cognitive abilities (Tabloski, 2014). AD is the most common type of dementia, accounting for eighty percent of all dementia diagnosis (Tabloski, 2014). AD is irreversible, progressive, and there is no cure (Biercewicz, Filipska, & Kedziora-Kornatowska, 2016). The purpose of this post is to describe what I have learned after watching, the Frontline documentary, Living Old. I will discuss what I did not previously…

The SVZ is where the neurons of the olfactory bulb are made, and the hippocampus has been linked to learning and memory, making it the prime place for neural plasticity (Anderson, 2015). The hippocampus also seems to be the supplier of NSCs for the rest of the brain. This gives…

from the Greek language. To break it down “A” means no “Myo” means muscle and “Trophic”means nourishment together it stands for no muscle nourishment. The word “Lateral” meaning the spinal cord in the body. ALS is an serious disease that affects the neurons, which controls the voluntary muscles when a muscle has no nourishment it becomes weak to control which then results into no communicating in the brain due to many repetitive head trauma. If the spinal cord gets affected due to ALS then the…

What is Blepharospasm might you ask? The word is split into two different words when you break it down, the word Blepharo which means ‘Eye Lid” and the word Spasm which means “uncontrolled muscle contraction. So with that being said it is an abnormal blinking or eyelid ticking or twitching resulting from any cause. (BEB) is a rare neurological disorder of muscles around the eyes. They have a lot of spasms that come and go called intermittent. Early stage symptoms of this disease can start with…

Lead Identification (LO): Lead compounds bind to target receptors, and shows potentially therapeutic pharmacological activity, and may contain similar structures and functional groups. Lead compounds are used as a foundation for drug development and may be modified structurally for greater pharmacodynamic efficiency and potency.1 One source of determining lead compounds is by assaying libraries through HTS. Researchers analyze the drug’s ADME properties (Absorption, Distribution, Metabolism, and…
