Which signs indicate illness may factor into behavior?

• A. Spitting, screaming and lying
• B. Threatening, pleading and loss of engagement
• C. Loss of memory/disorientation, delusions depression, hallucinations, anxiety, incoherence and altered response
• D. Deceptive behavior, loss of comprehension

Answer: (C)

The signs that illness may factor into behavior are internal cognitive and psychiatric changes that affect how a person thinks, feels, and communicates. Memory loss and disorientation point to cognitive impairment; delusions and hallucinations indicate psychotic symptoms; depression and anxiety reflect mood disorders; incoherence and altered response show disruptions in thought and communication. Together, these indicators suggest an underlying medical or mental health issue influencing behavior, not just outward actions. The other options describe behaviors that can arise from many non-medical causes such as frustration, manipulation, or stress, and don’t consistently signal an underlying illness.
