Brain Disorders Of The Nervous System

The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.

The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let 's take a look at the central nervous system.

In the organization of the Human Nervous System it is divided into sections such as the sensory system, which gathers and process information from the surrounding environment: motor systems which responds from environment by sending signals and information to facilitate movement behavioral responses and the associational system which is a meditator from most multifaceted and least problematic brain functions. Within these different functions of the nervous system it is divided into two components where these functions can happen the central nervous system that comprises of brain and spinal cord and peripheral nervous system that embodies nerves and ganglia.

The central nervous system is made up of the brain and spinal cord. The brain is connected to the spinal cord. The brain helps interpret information received from the spinal cord. Through the spinal cord signals are sent to the rest of body and back to the brain. Nerve cells (neurons) are found in the nervous system and they help communicate with other cells through electrical signals. Some of the nerve cells are coated with a myelin sheath. Myelinated neurons allow electrical signals to travel at a faster speed. When the myelinated part of the nerve cell is destroyed, Multiple Sclerosis (MS) can be the one to blame.

Amyotrophic Lateral Sclerosis (ALS) is a terminal disease, also known as Motor Neurons Disease, Charchot Disease and Lou Gehrig disease. ALS destroys the Central Nervous System (CNS) and causes damage to the upper and lower motor neurons in the brain. Signs and symptoms are characterized as: muscles weakness, muscle atrophy, twitching and reduced muscle reflexes. Eventually the patient will become paralyzed and rely on a tracheostomy and ventilator for breathing (ALS Association [ALSA], 2010).

Our nervous system is there to help to transfer the things our body feels and what we need. The nervous is broken up into two parts, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS controls the brain and the spinal cord, the PNS controls the nerves and the ganglia (a small mass of gray matter). Our body uses the spinal cord to send messages to the nerves so that it can control our organs and muscles.

The central nervous system consists of the brain and spinal cord. The brain takes information from the senses and processes it and it also makes decision sand sends commands to the body. The spinal cord carries information to and from away the brain. The peripheral system, on the other hand, is the system that allows communication between the central nervous system with the sensory systems. It also makes it possible for the brain and spinal cord to control muscles and

ALS, better known as Amyotrophic Lateral Sclerosis, is considered as a complex genetic disorder, in which multiple hereditary and environmental factors combine to cause this disease. This is seen as an illness of parts of the nervous system that control voluntary muscle movement. In ALS, the motor neurons (nerve cells that control muscle cells) are gradually lost. When these motor neurons turn out to be lost, the muscles they control become weak and ultimately nonfunctional. We see that “amyotrophic” is rooted in Greek origin meaning without nourishment to muscles and refers to the loss of signals nerve cells normally send to muscle cells. “Lateral” simply means to the side and refers to the location of the damage in the spinal cord. “Sclerosis” means hardened and refers to the toughened nature of the spinal cord in advanced ALS. This progressive neurodegenerative disease, that was first discovered 150 years ago, is associated with a life expectancy of approximately three years after symptom onset. In the United States, ALS is also known as Lou Gherig’s Disease, named after the Yankees Baseball player who passed away because of it in 1941. In the United Kingdom and other parts of the world, it’s often referred to as motor neuron disease in reference to the cells that are lost in the disorder (ALS Association, 2015).

ALS stands for amyotrophic lateral sclerosis. This disease is a progressive neurodegenerative disease. A progressive neurodegenerative disease is a disease that will affect your brain and spinal cord. Since this is a progressive disease, you will deteriorate as time goes by. In order to move, the motor neurons in the brain reaches the spinal cord and then reaches the muscles throughout the body. ALS affects the motor neurons and since this disease is progressive, it will continue to affect the motor neurons by killing it until there is you lose control. Once you lose control of your muscles,it will start to atrophy or waste away from no nourishment. Since the spinal cord is the main part that signals and controls muscle movement, that

As a medical practitioner, I was always fascinated by the complexities of the human nervous system. A few years later, during my neurology residency training, I developed special interests in the field of neurodegenerative disorders and dementias. These are largely non-curable disorders

Multiple sclerosis (MS) is a common disease that causes disruption to the electrical functions of the immune system resulting in cognitive and motor functions to become destroyed. 1 Multiple sclerosis affects 350,000 people in the United States, however; 2.3 million people globally are known to have multiple sclerosis. 2 This disease has throughout the years been on the rise all over the world. This increase could be due to people moving from one region to another. 2 Women tend to be at greater risk of having multiple sclerosis than men. Women typically develop symptoms at the ages of 20 and 40 years while men are known to develop symptoms at a later age. 2 Caucasian women are more susceptible to developing multiple sclerosis while African Americans have a lower chance of getting this disease. 1 Considering that MS is a disease that affects the nervous system, there is no concise explanation as to what causes this disease. Tobacco products have been linked to causing MS as well as some viruses and bacteria. 2 As viruses attack the brain and the spinal cord, the main compartments of our nervous system, this triggers an effect that causes extreme damage to the axons, specifically their mylenated areas.1 Multiple sclerosis triggers pain to the central nervous system, which destroys and prohibits proper functions. This disease is considered as being irreversible because of the damage done to the axons. 2 As damage to the axons is seen, lesions start to develop in the brain and

Amyotrophic lateral sclerosis (ALS) is a fatal progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord (Plowman, 2015, p.1151). The motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles in the body. When ALS is in a degenerate stage, this causes paralyzation and loss of muscle control, which can lead to one’s death. The ALS Association is a national nonprofit organization that is dedicated to fighting Lou Gehrig’s disease by providing support and information to those that have this disease, as well as spreading awareness effective for change. The ALS Association aims to discover new treatment for those living with Lou Gehrig’s disease, while actively seeking a cure

The manifestations of ALS are caused by the location of motor neuron death. When upper motor neurons die, the symptoms include problems controlling fine movements, spasms, dysphagia, dysphonia and dysarthria (Porth & Matfin, 2009). “Manifestations of lower motor neuron destruction include fasciculations, weakness, muscle atrophy, and hyporeflexia” (Porth & Matfin, 2009, p. 1284). Patients with early signs of ALS usually complain of feeling weak on one side, which is due to the slowing of electrical impulses to that group of muscles (Ignatavicius & Workman, 2010). Since the impulses are slowed, they are not receiving adequate electrical stimulation to move and the person feels weak. As the disease progresses, all the motor neurons die and are not regenerated so, the patient is left paralyzed, losing the ability to speak, swallow and breathe (Ignatavicius & Workman, 2010).

Regardless of which occur first, affected individuals will generally experience most of the symptoms as the disease progresses. Specifically, symptoms that include difficulty swallowing, moving, forming words, tight muscles, spasticity, and/or exaggerated reflexes occur when the upper motor neurons have been damaged. When lower motor neurons are damaged, symptoms such as muscle weakness, atrophy, cramping, and twitching will occur. In some cases, a few of the muscle neurons that
