Which of the following is a sign of a deteriorating mental state in a patient?

Withdrawal from previously enjoyed activities is a significant sign of a deteriorating mental state in a patient. This behavior often indicates a lack of interest or motivation, which can be a symptom of various mental health issues such as depression or anxiety. When a patient who previously participated actively in hobbies or social interactions begins to isolate themselves or show disinterest, it suggests a potential decline in their emotional or psychological well-being.

In contrast, improved communication skills and increased participation in therapy indicate positive developments in a patient's mental health. Consistent expression of emotions also reflects a healthy engagement with feelings, demonstrating that the individual may be coping better or expressing themselves in a more constructive manner. Each of these alternative responses points toward positive progress rather than deterioration.
