Alzheimer's disease typically progresses slowly in three general stages — mild (early-stage), moderate (middle-stage), and severe (late-stage). Since Alzheimer's affects people in different ways, each person will experience symptoms - or progress through Alzheimer's stages - differently. Overview of disease progression Mild Alzheimer's (early-stage) Moderate Alzheimer's (middle-stage) Severe Alzheimer's (late-stage) Did you know? People with cognitive changes caused by Mild Cognitive…

functional loss of neurons which is a gradual and progressive process. Various neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, etc. have been described by many biomarkers that are unusual in comparison to their baseline levels in the brain regions. Out of all the diseases, Alzheimer’s disease is the most prevailing disease in older patients with an average age greater than 65 years. Alzheimer’s disease (AD) is illustrated by irreversible neuron…

Alzheimer’s Disease is a form of dementia that causes memory loss and other intellectual abilities. A person can’t really prevent from inheriting or getting Alzheimer’s disease. There has been no cure, but treatments. Many studies have been done through animal models, help from organization to help increase the awareness for Alzheimer’s. This disease is caused by genetic, environmental, economic and other factors. There are three main health inequities that care involved in the condition of…

neural processing chapter it first started talking about how neurons work and what parts make up the neurons. The neurons contain three parts which are dendrites, axon, and the axon terminal. Dendrites are the structures that receive electrical messages from other neurons. In order for neurons to work, they will have to receive stimuli through their synaptic receptors. Once the dendrites receive the electrical messages from the other neurons it will transfer it to the axon which will convey the…

The spinal cord transmits information between the brain and the rest of the body. Injury to the spinal cord can cause paralysis and the inability to talk and permanent damage to the brain and legs . The spinal cord is made up of disks that protect nerves that run down the back. A spinal cord injury happens when one or more of the disks in the spine are broken or moved so that they are pinching the nerves. After you have surgery to move the bones off the nerve the problem is still not…

My favorite neurotransmitter is serotonin because it involves sleep, mood, anxiety, and appetite. Serotonin is found in the lower part of the brain it can either be excitatory or inhibitory, meaning it can produce excitement or to prohibit you from doing anything. Tryptophan is an amino acid that is found in cheese and nuts and once consumed it is turned into serotonin. Therefore, if one wants to know how to boost your serotonin levels up, one can go outside and be exposed to the sunlight or…

biological characteristics of aging in the brain and may contribute to changes in cognitive and motor functions in old individuals. Furthermore, aging-dependent norepinephrine (NE) loss occurs earlier than that of dopamine (DA) and a functional noradrenergic system may influence dopaminergic activities as evidenced by the fact that an intact noradrenergic system is neuroprotective on nigrostriatal dopaminergic neurons, and endogenous NE…

Alzheimer’s Association is nothing but facts. It is nothing to joke about. This ad is purple, the association’s main color. Within the main color, there are three other colors, blue, orange, and yellow. Each color represents something to do with the disease. Purple being the main color represents that they lost someone with Alzheimer’s, blue representing having Alzheimer’s, yellow representing support or care for someone with Alzheimer’s, and orange representing support for the cause and…

Alzheimer s disease is a slowly progressive, degenerative disorder of the brain that gets worse over time, becoming severe enough to interfere with daily tasks (Alzheimer Association). The disease was first described in 1907 by a German physician, Dr. Alois Alzheimer. He found abnormal deposits and tangle bundles of nerves fibers in the brain tissue of a woman that die of an unusual mental illness (Mental Health America). According to the Alzheimer Association, the disease is the sixth leading…

Marfan Syndrome Near the end of the 19th century a french doctor Antoine Marfan was the first doctor to notice the effects of a common disorder (Atinder). Marfan syndrome is a genetically inherited disorder that affects the connective tissues that exist through the body. Specifically, Marfan syndrome alters the FBN1 gene and this affects the production of fibrillin (NHGRI). Fibrillin is a protein that is produced by the body to give strength to connective tissue. Without this protein,…
