A young adult’s catatonia assessment illustrates why administration route and reassessment time matter. The later response did not establish that the first dose alone caused every improvement.
The reported patient was 23 and initially presented with prominent memory difficulties. After further evaluation, the clinical team identified catatonic features and recorded a Bush–Francis score of nine. An oral lorazepam challenge produced no change at five or fifteen minutes.
Fourteen hours later, eating and recall had improved and the score was four. A subsequent intramuscular challenge was followed by a score of zero at fifteen minutes. Lorazepam treatment and risperidone were then continued.
The first oral administration and the second intramuscular administration occurred at different stages of illness. Route, elapsed time, prior drug exposure, and clinical evolution cannot be disentangled in one patient. The report cannot determine which interval is optimal for every challenge.
At discharge, the patient still had deficits on cognitive testing despite resolution of rated catatonic signs. Improvement in a syndrome score therefore did not mean complete restoration of every cognitive function.
Record what was assessed, when reassessment occurred, and which route was used. An early negative observation and later improvement can both be accurate. Neither should be omitted to make a diagnostic test appear more decisive than the clinical record supports.
