Authors' Note: A psychiatric workup for mental disorders starts with the separation of causality into two streams. In the first, brain function, thoughts and behavior may be altered by subtle or unusual manifestations of disease in body systems outside the brain — these are sometimes termed exogenous. In the second stream, manifestations are attributable to disorder of the brain itself (usually of unknown cause) in patterns reflective of neurosis, schizophrenia and depressive illness. In somewhat archaic, but still utilized descriptions, psychiatrists may refer to this distinction as indicating organic versus non-organic mental disorders.
Brain tumours account for only a small portion of patients suffering such neuropsychiatric symptoms; however, medical practitioners frequently hope that such a correctable cause may be discovered.
Authors' Note: A course of high-dose synthetic corticosteroids, e.g. dexamethasone, may be used to help bring under control a severe exacerbation of a chronic illness, e.g. asthma, inflammatory diseases, or an initial presentation, e.g. anaphylaxis, septic shock or brain swelling. Owing to the common side-effect of drug-induced euphoria/mania and other psychiatric issues, doctors attempt to taper the high doses as soon as possible.
Authors' Note: A chronic subdural hematoma is a space-occupying intracranial lesion resulting from the body's failure to resorb blood that collected between the dural membrane and the brain parenchyma, usually caused by traumatic head injury. Whereas an initial expanding clot presents as a neurosurgical emergency, smaller clots, with a tendency to absorb fluid and expand gradually, may be later suggested only by chronic neuropsychiatric symptoms. In jargon used in actual medical settings and in televised fictional series, the term for the lesion responsible may be shortened to subdural.
