Chronic Conditions Constituting Substantially Limiting Impairment

Chronic Conditions Constituting Substantially Limiting Impairment Some chronic conditions may constitute substantially limiting impairments. Such conditions may be substantially limiting when active or may have a high likelihood of recurrence in substantially limiting forms. In addition, such conditions may require a substantial limitation of a major life activity to prevent or to lessen the likelihood or severity of recurrence. Some severe back problems and most forms of heart disease and cancer fall into this category. This category also includes illnesses, such as tuberculosis, that may lay dormant for long periods but can reemerge at any time in a substantially limiting manner. Similarly, episodic disorders, such as bipolar disorder, which remit and then intensify also fall into this category.
