If a person with Cerebral Palsy talks slowly, slurring their words, it does not mean that they can't understand you or don't know what to say. It simply means that there has been damage to the part of the person's brain which controls the person's speech and mouth muscles, not their ability to understand. Cerebral Palsy cannot be cured but it does not get progressively worse. However, the effects on the person can often change as the person grows older. For many people with Cerebral Palsy, disability is a reality.
Aids can simplify the basic tasks of everyday living such as eating, grooming and dressing.
Maintain eye contact, sit down if appropriate. Resist the temptation to interrupt or to answer on their behalf. At first the person's speech may be difficult to understand. After a while it usually becomes easier to follow.
