Ameliorating mental illness makes for more productive interrogation.You have NO — zip, zero, nada — information, evidence, or data upon which to conclude that there is any relationship between the diagnosis stated in the article and interrogation.
I do hope you are a better professional than you are a reader, or your clients are at grave risk.
Your ignorance is showing again. My data comes from years of working with the mentally ill and years of education and training. If you weren't ignorant about mental illness and the effect it has upon health, behavior and intellectual processes you would know what is accepted as common sense in the mental health professions. Although the article does not speak of the severity of the conditions mentioned, any of these diagnoses, if sufficiently severe, could cause profound disruptions in health, behavior and intellectual processes.
If you chose not to believe that, then don't.
