The MICROSTROKE expert system for stroke type diagnosis.

Abstract

MICROSTROKE is a prototype expert system designed to categorize and diagnose stroke types based on clinical information. The knowledge base of MICROSTROKE includes information from large stroke registries. The system first queries the physician-user for details of the patient's history, information about the onset of stroke, accompanying symptoms, and pertinent neurologic findings and then sums the individual data items, factors in the a priori odds, and arrives at the probabilities of different stroke types for a given patient. Specific diagnosis of stroke type includes thrombosis, embolus, lacune, intracerebral hemorrhage, and subarachnoid hemorrhage. Stroke type diagnoses by MICROSTROKE were correct in 72.8% of 250 cases in the Hamburg Stroke Data Bank, MICROSTROKE runs on any MS-DOS microcomputer and is intended as a practical aid for physicians not fully familiar with the diagnosis of stroke types.

The TOPOSCOUT expert system for stroke localization.

“…Adversely, the MICRO-STROKE expert system for the diagnosis of stroke type uses modified Bayesian inference techniques. 6 The backtracking algorithm was selected to restrict data acquisition to those questions that are needed to pursue relevant goals, TOPOSCOUT skips queries if pertinent information is supplied by other answers or if questions seem to be of limited value in the current diagnostic process; for example, not all neuropsychological phenomena 33 are requested for each patient. However, the inference engine simulates forward-chaining features by requiring the physician-user to enter complete results of a neurologic examination, providing the stroke registry capability.…”

“…6 Materials and Methods TOPOSCOUT'S knowledge data base is arranged entirely in the form of rules, presently 171. All data are derived from anatomic charts and textbooks 7 -and from 63 clinical publications.…”

Acute evaluation of the acute vestibular syndrome: differentiating posterior circulation stroke from acute peripheral vestibulopathies

“…To our knowledge, there is no reliable clinical scoring system that can accurately predict localisation of stroke to the posterior circulation for the patient presenting with AVS despite many attempts of developing such a tool . It is well known that manifestations of PCS are not well represented by the NIHSS, which is the most commonly used assessment scoring system used in acute ischaemic stroke …”

Survey of Soft Computing Techniques in Neuro Science

“…Klaus Spitzer, Andreas Thie, Louis R. Caplan and Klaus Kunze [1] (1989) have designed a prototype MICROSTROKE expert system to categorize and diagnose stroke type based on clinical information. The knowledge base of MICROSTROKE includes information from large stroke registries.…”
