How does this definition differ from the Americans with Disabilities Act (ADA or federal) definition?
The Washington State definition is broader and covers a greater number of impairments and medical, mental, or psychological conditions. Temporary conditions are covered under the Washington State definition, but are not covered under the ADA. Conditions that are ameliorated or mitigated by medication or other means are disabilities under the Washington State definition, but are often not considered to be disabilities under the ADA. Under the Washington State definition, there is no requirement that a condition must have an impact on a major life activity, or that the impact of the condition be substantially limiting.
