What is a defining characteristic of self-neglect?

Self-neglect is defined by an individual's inability to adequately care for their own basic needs, which encompasses physical, emotional, and often social aspects of well-being. This condition can manifest as poor hygiene, inadequate nutrition, inappropriate living conditions, or neglecting medical needs. It reflects a significant decline in the individual's capacity to tend to themselves, whether due to mental health issues, cognitive impairment, or a lack of resources.

The other options might reflect certain behaviors or circumstances surrounding an individual's psychological or social situation but do not encapsulate the essence of self-neglect. For instance, failure to share information with family pertains more to communication issues than to an individual's capacity for self-care. Lack of social interaction may signify social withdrawal or isolation but doesn't directly relate to the inability to provide for one's own essential needs. Refusal to leave home can point to various psychological states but does not necessarily equate to a failure to care for oneself.
