Amyotrophic Lateral Sclerosis, or ALS, is a degenerative disease that affects the nervous system. It is a deadly disease that cripples and kills its victims due to a breakdown in the body's motor neurons. Motor neurons are the nerve cells that control muscle contractions; they are located in the spinal cord and in the brainstem. ALS weakens the neurons to a point that all movement, including breathing, stops. The first symptom to develop is muscle weakness usually ones that are distant from the brain, such as the hands and feet, and then it slowly spreads through other muscle groups closer to the brain. Early symptoms are very slight and often go unnoticed. They begin as simple things, such as tipping or dropping things. Then follows cramping or twitching of the muscles then unusual fatigue of the arms and legs comes shortly. In more advanced stages the victim experiences shortness of breath or difficulty breathing and difficulty swallowing. Once the body is completely taken over the disease intellect, eye motion, bladder function, and sensation are the only abilities spared. Scientists still don’t know where or how it originated. ALS was first identified in 1869, by a French neurologist Jean-Martin Charcot. ALS is not contagious, but researchers are still unsure on the cause of the disease. Today there are three recognized forms of ALS: genetic, sporadic, and Guamanian. The genetic form of ALS appears to be inherited or passed down within a family, and about ten percent of ALS patients have a family history of the disease. An abnormal gene has been located in about half these families, but the cause of the remaining half is still unknown. The next, most common form, Is sporadic ALS. These patients have no family history of…
Amyotrophic Lateral Sclerosis
Amyotrophic lateral sclerosis (ALS), also referred to as Lou Gerhig’s disease and Charcot
disease, is a disorder that involves the death of neurons. ALS is characterized by stiff muscles,
the twitching of muscles and gradually worsening weakness due to muscle deterioration…
The purpose of the myelin sheath is to allow impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, the impulses slow down. This can cause diseases such as multiple sclerosis.
A number of studies have suggested that people who spend more time in the sun and those with relatively high levels of vitamin D are less likely to develop MS. Bright sunlight helps human skin produce vitamin…

Multiple Sclerosis and the Body
Multiple Sclerosis (MS) is a chronic, debilitating disease that affects the central nervous system (CNS). The immune system attacks the protective sheath around the nerves, which then causes a reduced or loss to bodily functions. Treatments for MS vary per person and symptoms each person experiences. It is unknown as to why MS affects some people, and not others.
Multiple Sclerosis affects the Central Nervous…
Amyotrophic lateral sclerosis
ALS is a nervous system disease which severely damages neurons in your brain and spinal cord. Neurons help your brain pass a message to muscles throughout your body, like your arms, and legs, these are called voluntary muscles. In particular, the upper and lower motor neurons are being destroyed. Because your neurons are being disturbed you have less control over your body. Eventually things that you need to survive will stop working like your lung or heart. ALS is…

I have found that this disease, Tuberous Sclerosis Complex (TSC) to be a very important diagnosis to be implemented in our society as serious concerns; as a community we should collaborate in increasing research until we find a cure. There are numerous of people who have been diagnosed with this disease, it is not very popular because the percentage of individuals with TSC does not make a very big percentage in the world as a whole. Many…
Multiple Sclerosis is a debilitating disease. The body’s immune system eats away the myelin that covers up the nerves. This damage causes interference in communication between the brain and the spinal cord. This can also result in deterioration of the nerves. People who have MS may lose the ability to walk or speak clearly.
ETIOLOGY AND RISK FACTORS:
• Cause is unknown but is a autoimmune disease which the body’s immune system attacks the own…
Lateral epicondylalgia (LE) also known as “tennis elbow”, is a prevalent musculoskeletal disorder classically characterised by pain over the lateral epicondyle of the humerus and marked deficits in the muscle and motor systems; typically associated with repetitive movement of the wrist and gripping tasks (Vicenzino, Cleland and Bisset, 2007). Although LE is commonly known as tennis elbow this term may be inappropriate as the condition is most ubiquitous (30-65% of all cases) in occupations attributing…
Tennis elbow also called lateral epicondylitis is a type of tendinitis -- swelling of the tendons -- that causes pain in the elbow and arm. These tendons are bands of tough tissue that connect the muscles of your lower arm to the bone. Despite its name, you can still get tennis elbow even if you've never been near a tennis court. Instead, any repetitive gripping activities, especially if they use the thumb and first two fingers, may contribute to tennis elbow. Tennis elbow…
Multiple sclerosis (MS) is a degenerative inflammatory disease that destroys the myelin
sheath which covers and insulates the nerve fibers and allows the currents to flow faster.
When the myelin sheath is destroyed (demyelination), lesions ( spots where tissue has been
damaged) appear, at different times, along the spinal cord and in different parts of the brain.
The first type/stage of MS that occurs is clinically isolated syndrome (CIS). CIS is one
episode of brain symptoms which suggests MS…
