Even if you do not have autism, cerebral palsy, epilepsy, or intellectual disability, you may still have a developmental disability if you meet the “fifth category.” The fifth category is really two categories, requiring either:

• You have a condition “closely related” to intellectual disability, or
• You require treatment “similar to” treatment for intellectual disability.

The law does not say what “closely related to” intellectual disability or “treatment similar to” that used for persons with intellectual disability means. The law does not say what types of conditions fall under the fifth category. Because the law is not clear, some regional centers rarely find people eligible under the fifth category.
