What is a potential negative impact of isolation or solitary confinement on mentally ill inmates?

Isolation or solitary confinement can significantly worsen the mental health of inmates who already have pre-existing conditions. The effect of isolation is known to lead to a deterioration in mental well-being, causing symptoms such as anxiety, depression, paranoia, and in some cases, psychotic episodes. For individuals with mental illnesses, the lack of social interaction and stimulation in solitary confinement can exacerbate feelings of loneliness and despair, leading to a more severe decline in mental health.

The environment of isolation not only removes individuals from crucial support systems but also deprives them of the structured activities that can help manage their conditions. Thus, the correct choice highlights the critical concern that isolation can intensify existing mental health challenges for vulnerable populations like mentally ill inmates.
