Mental illness affects the way a person thinks, feels and acts.

• A. True
• B. False
• C. It affects only mood
• D. It affects only thinking

Answer: (A)

Mental illness can influence how a person thinks, feels, and acts because it disrupts cognition, emotion, and behavior. It may change cognitive processes like attention, memory, and beliefs; it can alter emotions and mood regulation; and it often leads to changes in behavior such as withdrawal, agitation, or impulsivity. Because these conditions commonly impact all three domains, the statement is accurate. Limiting the impact to mood or thinking alone would miss how mental illness can manifest in how someone feels and behaves as well, which is why the true answer is the best choice. For example, someone with mood disorders might experience persistent sadness (feelings), slowed or disrupted thinking (cognition), and changes in daily activity (behavior).
