In a client with Cushing's disease who laughs inappropriately, which explanation best supports family understanding?

• A. Don't mind this; the disease is causing it.
• B. I need to check the client's cortisol level.
• C. The disease can sometimes affect emotional responses.
• D. Medication is available to help with this.

Answer: (C)

High cortisol levels from Cushing's disease can alter the brain areas that regulate mood and emotional responses, leading to affective changes like inappropriate laughter. Explaining this to the family helps them understand that the behavior is a symptom of the illness, not a deliberate choice by the patient. It normalizes the experience, reduces frustration, and encourages supportive, empathetic responses. While cortisol testing or medicine may be part of managing the disease, the best family-focused explanation is that the disease can sometimes affect emotional responses, so the laughter is related to the underlying hormonal impact rather than something under the patient’s control.
