Cerebral palsy is a term used to describe a group of chronic conditions affecting body movement and muscle coordination. It is caused by damage to one or more specific areas of the brain, usually occurring during fetal development; before, during, or shortly after birth; or during infancy. Thus, these disorders are not caused by problems in the muscles or nerves. Instead, faulty development or damage to motor areas in the brain disrupts the brain's ability to adequately control movement and posture.
'Cerebral' refers to the brain and 'palsy' to muscle weakness/poor control. Cerebral palsy itself is not progressive (i.e., it does not get worse); however, secondary conditions, such as muscle spasticity, can develop which may get better over time, get worse, or remain the same. CP is not communicable. It is not a disease and should not be referred to as such. Although cerebral palsy is not 'curable' in the accepted sense, training and therapy can help improve function.
