The other health impairment (OHI) disability category refers to a condition that causes limited strength, vitality, or alertness, including heightened alertness to environmental stimuli that results in limited alertness with respect to the educational environment due to a chronic or acute health problem and adversely affects a child's educational performance. This disability category, as explored in this chapter, may include one or a combined type of attention-deficit hyperactivity disorder, asthma, diabetes, epilepsy, a heart condition, kidney disease, sickle cell anemia, and Tourette's syndrome. As a result of the child's other health impairment, as described above, the child is prevented from receiving reasonable educational benefit from general education.
