Hydrocephalus is a genetic disorder commonly described as “water on the brain.” In actuality, this is a condition in which there is an excessive accumulation of cerebrospinal fluid (CSF), a clear watery fluid that surrounds the space between the brain and spinal cord, in the brain. Normally, the production together with the absorption process of CSF is specifically balanced to ensure that the brain tissue remains buoyant, that nutrients can be delivered and waste removed, and that there is a compensation for changes in intracranial blood volume. Hydrocephalus blocks this balanced flow as well as absorption, and on account of CSF being produced continuously, 16 oz each day to be exact, the blocking creates a surplus of CSF resulting in the said pressure against the brain tissue. The surplus accretion of CSF additionally motivates ventricular dilation in which the gaps between the brain, known as ventricles, abnormally widen. …show more content…
There has yet to be a cure for Hydrocephalus, but there are indeed treatments. Although, not many advances have been made in preventing, healing, or moderating Hydrocephalus. In fact, the device currently used as the dominant treatment was pronounced fifty years ago and has had the highest failure rates in comparison to any surgical remedy. Introducing said regimen, The National Institute of Neurological Disorders and Stroke (2013) explains, “Hydrocephalus is most often treated by surgically inserting a shunt system.” This operation revolves around the embedding of two catheters along with a valve. The valve influences the flow of CSF to generate an increasingly normal rate and direction. As an alternative, there is a procedure labeled as a ventriculostomy in which a hole is made in the underlying area of a ventricle or in between the ventricles. This functions as a funnel for the CSF to exit the cranial area. These methods are customarily permanent and must be monitored

Other than taking medications, there is another alternative such as surgery, such as “ventriculosmy, craniotomy, and carotid endarterectomy” (Kluwer, 2012). The patient also has the option of going to a rehabilitation center where the patient may be able to receive speech therapy, occupational therapy, and physical therapy. In addition, the rehabilitation center may also include “functional electrical stimulation” (Kluwer, 2012).
Cephalopods are known to be exceptionally intelligent by invertebrate standards and in some respects even rival “higher” vertebrates. These animals have many highly evolved sensory and processing organs that allow them to gain a greater understanding of their environment and their place within it. Due to their advanced structures, many of which are analogous to vertebrate structures, and abilities they have been widely studied. Their methods of learning have been of prime interest and many experiments have been conducted to determine the different ways in which octopuses can learn. From these experiments four main kinds of learning have been identified in octopuses: associative learning, special learning,

Liopleurodon lived in ocean which covered the Europe at that time. There were two species of Liopleurodon which lived in Jurassic Period.
During the nineteenth century a variety of alternative medical traditions became popular in the United States. There was a shift in how people began to view their physical, mental, and emotional health. A type of alternative medicine that quickly became popular in the United States and Europe was the tradition of hygeiotherapy. This form of treatment included hydropathy a type of water-cure treatment and combined that with exercise, dietary reform, sexual restraint, and any behaviors that were viewed as unhealthy.

Epilepsy, also known as “seizure disorder,” or “seizure attack,” is the fourth most common neurological disorder known to mankind, affecting an estimated 2.3 million adults and 467,711 children in the United States. Unfortunately this disorder is becoming far more common and widespread worldwide. This staggering number of cases of people suffering from Epilepsy also involves an average growth rate of 150,000 new cases each year in the United States alone. Generally, many of the people who develop who are a part of the new are mainly either young children or older adults. Your brain communicates through chemical and electrical signals that are all specialized for specific tasks. However, through the process of communication, chemical messengers, also known as neurotransmitters can suddenly fail, resulting in what is known as a seizure attack. Epilepsy occurs when a few too many brain cells become excited, or activated simultaneously, so that the brain cannot function properly and to it’s highest potential. Epilepsy is characterized when there is an abnormal imbalance in the chemical activity of the brain, leading to a disruption in the electrical activity of the brain. This disruption specifically occurs in the central nervous system (CNS), which is the part of the nervous system that contains the brain and spinal cord. This causes an interruption in communication between presynaptic neurons and postsynaptic neurons; between the axon of one neuron, the message sender and the dendrite of another neuron, the message recipient. Consequently, the effects that epileptic seizures may induce may range anywhere from mild to severe, life-threatening ramifications and complications. There are many different types of seizures associa...
No matter what, where, or who you are, water is a necessary component to keeping any organism alive. Although water is essential for life, in many places, clean drinking water is hard to find. There are many consequences to drinking contaminated water. Every year, three to five million people are attacked by water-borne diseases and over 100,000 of them die. One fatal disease that can kill within hours is cholera.
Brain aneurysms practically go unnoticed and tend to have few to no symptoms until the rare occasion when the aneurysm ruptures. The bursting aneurysm causes bleeding in the brain and then often leads to a stroke. This is exactly what happened to my great-aunt Judy who survived a brain aneurysm and stroke.
This source states that women living with epilepsy seem to face different issues than males with epilpesy do. The source states that the two sex hormones inside a woman's body, progesterone and estrogen, play a role in influencing seizures as both of these hormones interact with brain cells. Usually, there are equal amounts of progesterone and estrogen inside a woman's body. However, the problem occurs when the balance of these becomes unequal. It explains that estrogen is an excitatory hormone which basically means that it "makes brain cells give off more of an electrical charge". Prosgesterone, however, is an inhibitory hormone, meaning that it calms the cells - that have been electrically charged by the estrogen - down. The problem arises when the body starts producing more estrogen than progesterone which "can make the nervous system excitable" and can make a woman with epilepsy more exposed to seizures. The source emphasises that a change in hormones don't cause the seizures but they are able to inluence the occurence of seizures. About 10% - 12% of women (with epilepsy) have catamenial epilepsy which means that their seizures are directly affected by their menstrual cycle. The seizures tend to occur when a lot of estrogen is present during the body such as during ovulation. For some others, the seizures can occur when the progesterone levels in the body drop such as during menstruation. It is said that as many as" 40% of menstrual cycles in women with epilepsy do not release an egg" and that women with epilepsy generally produce eggs less often than the normal ...
Meningitis is defined as inflammation of the meninges, which are the thin membranous covering of the brain and spinal cord. There are different variations of the disease which include bacterial, viral, fungal, parasitic, and non-infectious.
Hypertrichosis, which is also known as Ambras Syndrome or Werewolf Syndrome, is excess growth of hair on parts of the body. Hypertrichosis can either be generalized meaning it covers the whole body or localized meaning it is only on a certain area. There are three different hair types that may be involved. They include Lanugo (long and silky), Vellus (replace Lanugo after birth except on the scalp and eyebrows), and terminal (course, thick, and pigmented). Generalized can include all three types while acquired usually involves vellus that turn into terminal. Along with being generalized or localized, Hypertrichosis is also separated into congenital or acquired classifications. Congenital means that this disorder was present at birth and may have been caused by mutations in the genes. While acquired means that it became present over time. The cause for congenital is typically genetics while the cause for acquired is influence by medical conditions such as metabolic disorders, cancer or even oral and topical drug treatments. Congenital Hypertrichosis Lanuginosa is thought to be caused by mutations on the eighth chromosome or spontaneous gene mutations. The main sign of Hypertrichosis is excess hair growth, especially in places that hair does not typically grow in. Symptoms of Hypertrichosis may be present because of underlying conditions or chemical imbalances and the side effects of some medications. When a patient is being diagnosed with Hypertrichosis, a Doctor will determine if this was congenital or acquired. Congenital has no cure but acquired are typically triggered by factors that can be reversed or lessened so the Doctor could try to find these triggers. Hypertrichosis can cause cosmet...
Swallowing is a complex action involving the muscles and nerves within the pharynx and esophagus, a swallowing center in the brain, and nerves that connect the pharynx and esophagus to the swallowing center (medicine net). But what would happen if it became difficult to swallow, or even worse, you lost the ability to swallow? What are the causes of this and what treatments are available? There are many specific causes that include physical obstruction of the pharynx or esophagus, diseases of the brain, diseases of the smooth muscle of the esophagus, diseases of skeletal muscle of the pharynx, and miscellaneous diseases (e.g., Parkinson’s disease and dementia) (Dysphagia, n.d.). Intervention for patients with dysphagia is diet modification of solid foods and/or liquids.
During this corse I lean multiple ways that the brain changes mentally as a person ages, such as cognitive development. There are many theories about how cognitive development occurs in children. Jean Piaget had a theory of cognitive development that included 3 different stages, the sensorimotor stage, the preoperational stage, and the concrete operational stage. The stages begin with learning though senses and actions, to have magical and egotistic thinking, to being able to think logically but not abstractly. Piaget also believed that people’s brains create schemas, almost like folders for the ideas of the brain, in order to organized they can understand them. When someone takes in new information,
In modern society, we are faced with an increased demand for college graduates with a variety of skills. In order to meet the demands of an ever changing job market, we must be skilled in subjects such as math, reading and science. One subject that needs to be addressed is math. We use arithmetic to calculate numbers, exchange money and understand math concepts. That is why it is imperative that educators reach out to students with Dyscalculia with strategies, such as explicit instruction to help students overcome their problems in math. I will examine dyscalculia, its effect on the individual’s education and interventional approaches used to mitigate its effects.
