Prominent delusions or hallucinations are a direct physiological consequence of another medical condition.

Known Medical Conditions Associated with Psychotic Disorder

Neurological conditions (neoplasms, cerebrovascular disease, Huntington's, multiple sclerosis, epilepsy, auditory or visual nerve injury, deafness, migraine, CNS infections); endocrine conditions (hyper-/hypothyroidism, hyper-hypoadrenocorticism); metabolic conditions (hypoxia, hypercarbia, hypoglycemia); fluid or electrolyte imbalances; hepatic or renal diseases and autoimmune disorders with CNS involvement (lupus).

Catatonia

Presence of 3 or more of 12 psychomotor features; essential feature is marked psychomotor disturbance that may involve decreased motor activity, decreased engagement during assessment, or excessive and peculiar motor activity.

Stupor

No psychomotor activity, not actively relating to the environment.

Catalepsy

Passive induction of a posture held against gravity.

Waxy flexibility

Slight, even resistance to positioning by examiner.

Mutism

No, or very little, verbal response (exclude if known aphasia).

Negativism

Opposition or no response to instructions or external stimuli.

Posturing

Spontaneous and active maintenance of a posture against gravity.

Mannerism

Odd, circumstantial caricature of normal actions.

Stereotypy

Catatonic Disorder Due to Another Medical Condition

Presence of 3 or more catatonic psychomotor features that are direct physiological consequence of another medical condition.

Known Medical Conditions Associated with Catatonia

Neurological conditions (neoplasms, head trauma, cerebrovascular disease, encephalitis) and metabolic conditions (hypercalcemia, hepatic encephalopathy, homocystinuria, diabetic ketoacidosis).

Unspecified Catatonia

Catatonia-like symptoms cause clinically significant distress or impairment but nature of underling mental disorder or other medical condition is unclear, or full criteria are not met, or insufficient information to make a more specific diagnosis.

Other Specified Schizophrenia Spectrum and Other Psychotic Disorder

Related symptoms that cause clinically significant distress or impairment but does not meet full criteria and clinician specifies the reason (e.g. persistent auditory hallucinations, attenuated psychosis syndrome, delusional symptoms in partner of individual with delusional disorder).

Unspecified Schizophrenia Spectrum and Other Psychotic Disorder

Related symptoms that cause clinically significant distress or impairment but does not meet full criteria and clinician does not choose to communicate the reason, possibly due to insufficient information.
