Signs and Symptoms Symptoms of hydrocephalus differ with age, disease development, and individual variations in acceptance to the illness. For instance, a child's capability to compensate for enlarged CSF pressure and extension of the ventricles varies from a grown-up's. The infant skull can enlarge to accommodate the buildup of CSF because the sutures (the fibrous joints that attach the bones of the skull) have not yet closed. In infancy, the clearest sign of hydrocephalus is frequently a fast…

Mitochondria, LHON The Organelle The most well known function of the mitochondria is to produce energy for the cell. It does this by regulating cell metabolism and respiration. Mitochondria carry out multiple other functions that are extremely important (such as various forms of signaling) The mitochondria also contains DNA which can have a direct effect on some functions of the human body if there is a mutation. ( Mitochondrion.(2016, October 9)) Word count 63 (not including headings or…

There are a few physical and mental changes which occur with aging. One of the most common physical change with aging is dealing with the skin. Often when people get older their skin becomes thinner and loses elasticity in the outer surfaces. Another physical change which occurs with aging is dealing with our bones and joints. Over the years our bones become more less dense and often results in a disease called osteoporosis. Osteoporosis can occur in both males and females also at any age. As we…

landing at its destination at the thalamus; thus, making it an ascending pathway. This pathway is further divided into three levels of neurons for transmission: The first level is where the sensation is translated into an electrical impulse from pseudounipolar neurons branching from the skin leading to the dorsal root ganglion where its axons synapses with the neuron at…

Among annually 2.4 million eye injuries in the United States, 40,000-60,000 of them trigger blindness as a consequence of Blunt Trauma Impact (BTI). The injury as a result of BTI to the eye could be minimized if and only if the process and detail of that were thoroughly available. Numerical models, such as Finite Element (FE), might be applicable since experimental measurements on the detail of injury in each component of the eye is almost impossible. In this study, in order to understand…

When diagnosing the patient, it is important to take all signs into account and differentiate between conditions with similar symptoms, especially in patients whose symptomology matches a plethora of illnesses. Differential diagnosis is used to distinguish between two or more medical conditions that have similar symptoms. Differential diagnosis aids in increased diagnostic accuracy of the diagnosis so that patients can be effectively treated. Differential diagnosis is used often, especially in…

ALS Amyotrophic Lateral Sclerosis is a progressive disorder that is inherited or acquired. It affects motor neurons. Motor neurons are cells that are in the brain, brain stem and spinal cord and their function is to carry an electrical signal to a muscle and trigger it to contract or relax. Medical terminology, a means without, my is muscle and trophic is nourishment. Lateral is pertaining to the side/direction that is affected and sclerosis is an abnormal condition of hardening. It was…

Alzheimer's is a type of dementia, which is a mental ability that affects your brain cells which results in the interference with your daily life. Dementia can also be called a neurodegenerative disease where the function of neurons do not work properly in the brain. Since neurons do not reproduce, so once they are damaged, our bodies can not replace them resulting in the death of brain cells over time. This disability affects your memory which makes it hard for an individual to complete simple…

and a traumatic head injury as a child (Mayo Clinic, Aug. 16, 2013, mayoclinic.org). In addition to their own unique diagnosis, there are also some general symptoms to be aware of, for example, uneven variation in muscle tone, delays in reaching motor skill milestones, overly tense or overly limp bodies (especially with infants.), or difficulty walking (Mayo Clinic, mayoclinic.org). Cerebral Palsy is classified under 4 types. The most common type of Cerebral Palsy is Spastic Cerebral Palsy,…

Alzheimer's is a debilitating brain condition that impairs the memories of anyone afflicted with it. This disease begins as something simple as remembering current events. However if you can not remember something that recently happened do not diagnose yourself with Alzheimer’s. As Alzheimer’s progresses it causes trouble focusing and doing daily actions. Confusion or frustration when doing simple tasks, extreme mood swings, disorientation and trouble communicating are all signs of…
