Common questions
Frequently Asked
4
How does a clinical diagnosis differ from a physical diagnosis?+
A clinical diagnosis rests only on the patient's reported symptoms. A physical diagnosis requires findings from direct examination or testing.
When is a clinical diagnosis alone insufficient for a legal standard such as insanity?+
A clinical diagnosis supplies medical information but does not automatically satisfy legal criteria such as the inability to form mens rea or appreciate wrongfulness. Additional evidence tying the diagnosis to the legal test is required.
Why might a court order a psychiatric evaluation for an indigent defendant?+
When the defendant's mental condition is relevant to culpability or punishment, a clinical diagnosis obtained through expert assistance can be essential to mounting an adequate defense.
Does a clinical diagnosis of intellectual disability automatically bar the death penalty?+
The diagnosis supplies evidence of the disability, but the court must determine whether the condition meets the legal standard of significantly subaverage intellectual functioning and adaptive deficits that reduce culpability.
