Or, as they say now, the cerebral palsies - athetoid cerebral palsy, for example, or spastic cerebral palsy.
People with cerebral palsy have difficulty making precise movements, which can make it difficult to speak or write. Proper positioning or seating, appropriate speech, occupational and physio therapy, communication device or switch use training, exercise, and good teaching can all help.
The performance difficulties of people with cerebral palsy sometimes lead to their being wrongly regarded as intellectually disabled because of their inability to undertake standardised tests. This often results in low expectations and inappropriate educational placements.
People with cerebral palsy often have severe communication impairments, and here DEAL can usually assist them.
