This condition is currently not recognized as a diagnosable issue by psychiatric journals such as the Diagnostic and Statistical Manual of Mental Disorders-IV by the American Psychiatric Association or the tenth revision of the International Statistical Classification of Diseases and Related Health Problems by World Health Organization (WHO). Physical examination When examined, patients with<unk>  fail to recall names, recent experiences and are poorly oriented for location, date, and time. Moreover, their blood pressure and respiratory rate are increased. Additionally, mental status examination using questionnaires and three diagnostic tests are taken, including drawing a clock-face, The Face-Hand test and Hidden figures tests. Patients suffering from<unk>  tend to make obvious mistakes in these tests, for instance drawing a clock-face with incorrect numbering or missing clock hands. Differential diagnosis Upon acute onset of the symptoms, an instant investigation for a toxic or systemic cause is undertaken. Prominence of thought disorder, grandiosity and delusional ideation, and catatonic signs indicates the diagnosis of acute schizophrenia, bipolar disorder and catatonia respectively. Diagnostic complications arise as these signs are also often the notable feature of<unk> . With the cause undetermined,<unk>  diagnosis is usually justified with the presence of both mania and delirium regardless of the catatonic symptoms. Distinguishing between<unk>  and catatonia<unk>  and catatonia are regarded as "overlapping syndromes", making differential diagnosis essential when catatonic signs are observed. Thus, researchers must distinguish between excited catatonia and<unk> , and among malignant catatonia, excited catatonia, and neuroleptic malignant syndrome (NMS). When catatonic features are prominent, it is diagnosed as excited catatonia and when absent or subtle, it is identified as<unk> . Alternatively, the presence of delirium is recognized as the discerning factor. A difference between the two is that catatonia is viewed from a movement aspect, whereas delirium from consciousness. Nevertheless, a formal set of diagnostic criteria is required to distinguish between<unk>  and catatonia. Failure to diagnose<unk>  appearing as catatonia could lead to deleterious consequences and, in worse cases, death.
