A distinct psychomotor syndrome marked by markedly decreased, excessive, or abnormal motor activity (e.g., stupor, catalepsy, waxy flexibility, mutism, negativism, posturing, mannerisms, stereotypy, agitation, grimacing, echolalia, echopraxia), diagnosed when at least 3 of 12 characteristic features are present, regardless of the underlying condition it accompanies.
Catatonia is a cluster of motor and behavioral abnormalities — ranging from complete unresponsiveness and immobility to purposeless excessive movement — that DSM-5-TR treats as a syndrome that can be layered onto many different underlying conditions, rather than a standalone disorder in most cases. It's most often coded as a specifier attached to a psychotic, mood, or other mental disorder, but can also arise directly from a general medical condition, or be diagnosed as unspecified when the underlying cause isn't yet clear.
Can occur at any age and in the context of a wide range of underlying psychiatric or medical conditions; not specific to any single developmental period.
Can be severe and medically urgent — immobility, refusal of food/fluids, and extreme agitation each carry direct medical risk (malnutrition, dehydration, blood clots, exhaustion), which is why catatonia is treated as requiring prompt recognition and treatment regardless of the underlying diagnosis.
Autonomic instability (malignant catatonia) is a medical emergency requiring urgent intervention; catatonia shows a distinctive, often dramatic treatment response to benzodiazepines and electroconvulsive therapy that is itself sometimes used to support the diagnosis.
Presentations of extreme withdrawal, mutism, or unusual posturing should be carefully distinguished from culturally sanctioned religious, meditative, or trance states, which are not evidence of catatonia despite superficial similarities in stillness or unresponsiveness.
A common misconception is that catatonia only occurs in schizophrenia. It is a transdiagnostic syndrome most often associated with mood disorders (especially bipolar and depressive episodes) rather than schizophrenia specifically, and can also arise from general medical conditions with no primary psychiatric diagnosis at all.
If catatonic-appearing features developed shortly after starting or increasing an antipsychotic medication and are accompanied by fever and elevated creatine kinase, reconsider Neuroleptic Malignant Syndrome and a medication-focused emergency workup instead.
A patient with a known bipolar I disorder diagnosis develops sudden mutism, waxy flexibility when limbs are repositioned, and prolonged immobile posturing during a mood episode — meeting criteria for the catatonia specifier attached to the underlying bipolar disorder, and requiring urgent medical attention regardless of the psychiatric context.
Know
Catatonia is a distinct psychomotor syndrome (3 or more of 12 characteristic features) that can be layered onto psychotic, mood, or other mental disorders, arise from a general medical condition, or appear as unspecified when the cause is not yet clear — always requiring prompt recognition given its medical urgency.
Notice
In a case, notice the specific combination of psychomotor features (stupor, waxy flexibility, mutism, negativism, posturing, echophenomena) rather than nonspecific withdrawal or slowing, and check for a medication history or known medical illness that could point toward Neuroleptic Malignant Syndrome or a medical cause instead.
Distinguish
Distinguish from Neuroleptic Malignant Syndrome by antipsychotic exposure history, fever, and elevated creatine kinase; distinguish from ordinary depressive psychomotor retardation by the presence of the specific catatonic features (waxy flexibility, echophenomena, posturing) rather than general slowing alone.
Recognize
At least 3 of 12 characteristic features (stupor, catalepsy, waxy flexibility, mutism, negativism, posturing, mannerisms, stereotypy, agitation not influenced by external stimuli, grimacing, echolalia, echopraxia) present, taught as three related DSM-5-TR entries: the catatonia specifier (added to a psychotic, bipolar, depressive, or other mental disorder diagnosis), Catatonic Disorder Due to Another Medical Condition (when a physiological medical cause is established), and Unspecified Catatonia (when catatonia is clearly present but the underlying disorder or medical condition cannot yet be determined, e.g. in an acute/emergency setting).
Distinguish
Distinguish from Neuroleptic Malignant Syndrome by antipsychotic exposure history, fever, and elevated creatine kinase; distinguish from ordinary depressive psychomotor retardation by the presence of the specific catatonic features (waxy flexibility, echophenomena, posturing) rather than general slowing alone.
Neuroleptic Malignant Syndrome shares features like rigidity and autonomic instability but is specifically triggered by antipsychotic medication exposure and includes hyperthermia and elevated creatine kinase as core features, requiring a different, medication-history-driven workup. A general medical/neurological cause (e.g. encephalitis, metabolic disturbance) must always be considered, since Catatonic Disorder Due to Another Medical Condition requires evidence linking the syndrome directly to a physiological condition. Severe psychomotor retardation in depression can resemble catatonic stupor but lacks the specific combination of features (e.g. waxy flexibility, echophenomena) required for the catatonia specifier.
Profound psychomotor slowing in depression is sometimes assumed to simply be 'severe depression' without considering whether the specific catatonic feature threshold is actually met, delaying recognition of a treatable, urgent syndrome.
Catatonia is popularly associated almost exclusively with schizophrenia, reflecting outdated nosology (the old 'catatonic subtype' of schizophrenia); DSM-5-TR treats catatonia as its own transdiagnostic syndrome most often associated with mood disorders.
Because both can present with rigidity and reduced responsiveness, one can be missed while the other is treated, delaying appropriate management.
Reason
Apply
Recognize akathisia as a medication-induced movement disorder that can be mistaken for worsening psychiatric agitation, and distinguish it from catatonia.
Recognize the catatonia specifier as a transdiagnostic psychomotor syndrome, distinguished from schizophrenia and from ordinary depressive psychomotor retardation.
