Physical disability definition and classification

Physical disability

The vision we have of the person with physical disabilities has varied over the years; some years ago; we saw that people were relegated to their homes, unable to socialize, much less to have job options; this condition are improving daily, and governments are becoming more aware of implementing policies to make cities more friendly places to the person living with a disability. We found people with disabilities who occupy important positions in politics, prominent businessmen, musicians, athletes, artists, etc. ..

Sclerosis, because it produces scar tissue hardening in the damaged areas.
Multiple scattered areas because they affect the central nervous system, where the symptoms can be severe or mild, and can present with a period of unpredictable and erratic, and also can vary in each patient. There are two basic forms of MS: The most current outbreak is manifested (symptoms) spaced, that can last days or weeks. Outbreaks are not necessarily cumulative and between each other, may take months or years. The second one is chronic, more complex, progressive outbreaks. In addition, MS can be expressed in other ventures.

Cerebral Palsy

It is caused by damage one or more specific areas in the brain, usually during fetal development, but may also occur just before, during or shortly after birth, as well as by trauma (accidents).

Parkinson’s Disease

In addition, regular or irregular have tics and affects one or more parts of the body. These muscle disorders do not affect other brain functions, such as personality, memory, emotions, senses; intellect and sexual activities remain quite normal.
