Cerebral Palsy (CP) is a type of disability caused by brain injury at birth.
Much like autism, CP is a spectrum. Some people are mildly affected – like Łukasz (aka Lennart) – while other people have severe effects and cannot function without aid – like Gerard (pictured on the right).
People with cerebral palsy experience various problems with muscle tension: either too much or too little. This results in abnormal walking patterns and trouble keeping balance. Some types of CP also cause loss of muscle control, resulting in twitching. Most severe cases mean life-long pain from tense (spastic) muscles and even complete paralysis.
If all this wasn’t enough, CP can also appear as part of a combo with blindness, deafness, or mental disability.
Note that this is only a very basic description of CP. If you’d like to know more, check out the Wikipedia page on cerebral palsy.
