Sentence Structure Analysis in Patients with Ischemic Stroke

Abstract

Introduction. The definition of brain health and the best method of promoting optimal brain health is an American Heart Association/American Stroke Association initiative. Intact cognitive function is important following an ischemic stroke for successful rehabilitation. Therefore having a simple metric of cognitive function would be optimal for all health professionals.
Aim. The aim of this study was to investigate if using Developmental Sentence Scoring (DSS) on sentences written by patients on a Mini-Mental State Examination (MMSE) could provide a simple metric of cognitive function.
Material and Methods. This secondary analysis reports on sentences written by patients after an ischemic stroke using quantitative and conventional content analysis methods.
Results. A mean score of 24.38 (SD±13, range 9–30) was found in the 76 patients who had written something in the course of the Folstein MMSE. The number of words ranged from 1 to 16 with the greatest number (21) averaging 5 words. The DSS ranged from 0–11 with a mean of 4. The mean Folstein MMSE (N=30), was 27.53 (SD±2.74, range 18–30) in patients who consented to a home visit 3 years after their stroke. Twenty seven of the 30 patients had written something and the number of words ranged from 1 to 12 with the greatest number (10) averaging 5 words. The DSS ranged from 0–12 with a mean of 4. Conventional content analysis revealed an overarching pattern articulated in two ways: (1) Awareness of recent space and time and remote memories of people and place (2) Expression of the self as person.
Conclusions. This secondary analysis provides normative data and a rich description of cognitive function in a group of individuals describing the DSS at baseline and again at 3 years after stroke but the sample was too small to be able to provide a simple metric of cognitive function.
