Mental illness can be what, allowing individuals to recover and show no symptoms?

The correct answer is that mental illness can be treated, allowing individuals to recover and show no symptoms. Treatment for mental illness encompasses a range of interventions, including therapy, medication, and lifestyle changes, tailored to the individual's needs. Effective treatment can help individuals manage their symptoms, gain insight into their issues, and develop coping strategies, leading to significant recovery and a return to normal functioning.

While managing mental illness is also a critical aspect of treatment, the term 'treated' emphasizes the potential for individuals to experience a complete recovery where symptoms may no longer be present. This distinguishes it from mere management, which implies ongoing symptoms may still need addressing. The other options, such as ignored or documented, do not reflect the proactive and supportive methods required for recovery. Ignoring mental illness can lead to worsened conditions, and while documentation is important in understanding and tracking mental health issues, it does not contribute to recovery in the same way treatment does.
