Individuals exhibiting this disorder commonly present as emotionally aloof, demonstrating minimal interest in social connections.
Their preference is for solitude, with a tendency towards introspection and potentially a vibrant inner imaginative world.
They do not pursue or derive pleasure from close relationships and often appear unresponsive to both commendation and censure.
These distinguishing features separate schizoid personality disorder from conditions such as avoidant or schizotypal disorders.
Consequently, Rahi's conduct most closely adheres to the definition of schizoid personality disorder.
