Select the Statement That Correctly Describes Multiple Sclerosis

Question: Select the statement that correctly describes multiple sclerosis?

A. This fatal disease leads to severe and progressive retentiveness loss.

B. This fatal affliction attacks the peripheral nervous system.

C. This nonfatal affliction is characterized by severe memory loss.

D. This nonfatal disease disrupts the central nervous arrangement (CNS).

The answer is selection D. This nonfatal disease disrupts the central nervous arrangement (CNS).

Explanation:
Multiple sclerosis (MS) is a chronic disease affecting the central nervous system (the brain and spinal string). MS occurs when the immune system attacks nervus fibers and myelin sheathing (a fatty substance that surrounds/insulates healthy nerve fibers) in the brain and spinal string. This attack causes inflammation, which destroys nerve cell processes and myelin–altering electrical letters in the brain.

MS is unpredictable and affects each patient differently – some individuals may be mildly affected, while others may lose their ability to write, speak or walk. It is non possible to predict how multiple sclerosis (MS) volition progress in whatever individual.

Some people have balmy symptoms, such equally blurred vision and numbness, and tingling in the limbs. In astringent cases, a person may experience paralysis, vision loss, and mobility bug. However, this is not common.

It is difficult to know precisely how many people have MS. Co-ordinate to the National Institute for Neurological Disorders and Stroke (NINDS), 250,000–350,000 people in the United States are living with MS.

The National Multiple Sclerosis Gild estimates the number could exist closer to one million. There are several courses of multiple sclerosis that have been described:

Relapsing-Remitting Multiple Sclerosis (MS)

At the time of diagnosis, 90% of patients will have the relapsing-remitting class of the disease. This course of multiple sclerosis is characterized by the onset of neurological symptoms over a period of hours to days. Mutual symptoms of a relapse may include:

• Fatigue
• Numbness
• Tingling
• Blurred vision, double vision or loss of vision
• Unsteady gait
• Weakness

These symptoms tend to persist for days or weeks, and and so disappear partially or completely on their own or with treatment. Patients may and then remain symptom-gratis for weeks, months or even years (known every bit remission). Without treatment, most people with MS will develop disease symptoms that will gradually worsen over time (known equally relapsing).

Secondary Progressive Multiple Sclerosis (MS)

If the relapsing-remitting condition changes to a point where at that place are no discernable relapses and remissions; the grade of the affliction has transitioned to secondary progressive MS. All those with secondary progressive MS began the disease with a relapsing-remitting illness course. In secondary progressive MS, symptoms accumulate and worsen without any remission.

There may be periods where symptoms are stable, only the overall form is one of worsening over time. Ofttimes an individual will describe a change in their abilities when comparison current role to past role but without identifying an episode that led to the worsening. Sometimes, afterwards the onset of secondary progressive MS an individual may experience a relapse. The form would then be considered secondary progressive MS with relapses.

Primary Progressive Multiple Sclerosis (MS)

About 10-15% of patients will have gradual worsening from the start of their MS disease. This is referred to as primary progressive MS. People with master-progressive MS describe a gradual change in mobility; oftentimes walking, over fourth dimension. They often describe heaviness and stiffness in the lower limbs. People with primary-progressive MS almost never have an exacerbation (relapse). If a relapse occurs after a primary progressive course is well established, the pattern is known equally Progressive-Relapsing MS.

Beneficial Multiple Sclerosis (MS)

Beneficial MS is a balmy course where an individual will accept a mild disease later having MS for nearly 15 years. This occurs in about 5-10% of patients. There is no good way of predicting which patients will follow this grade. The only way to identify benign MS is AFTER someone has had the diagnosis of MS for at least xv years and has had no evidence of worsening (both in functional ability and as evidenced on the MRI). Benign MS cannot be predicted at the time of diagnosis or even after a few years with MS.
