Cognitive Impairment and Outcome of Acute Ischemic Stroke.

June 20, 2020 updated by: Ahmed Esmael, Mansoura University Hospital

Correlation of Alberta Stroke Program Early CT Score (ASPECTS) With Cognitive Impairment and Outcome of Acute Ischemic Stroke

The aim of this study is to assess the use of ASPECTS and stroke biomarkers to predict the outcome and cognitive impairment in acute ischemic stroke.

Detailed Description

150 patients (79 males, and 71 females with a mean age of 64.05±11.55 years) were included in this study presented by acute middle cerebral artery territory ischemic stroke. Vascular risk factors were determined from the history taking. Assessment of GCS and NIHSS at the initial presentation was done to assess the stroke severity. Cognitive functions were evaluated in all study participants by the Montreal Cognitive Assessment (MoCA) Arabic version. An initial and follow up non-contrast CT brain was done after 7 days which were assessed by ASPECTS. Functional outcomes in stroke cases were assessed after three months by Glasgow Coma Scale, National Institutes of Health Stroke Scale and modified Rankin Scale. Biomarkers of cognitive impairment like ESR, CRP, S100B, MMP9 and glutamate were evaluated.

Study Population

79 males and 71 females with a mean age of 64.05 ±11.55 were included in this study and were admitted with the first attack of acute MCA territory infarction within 2 days from the onset and aged more than 18 years. Acute ischemic stroke (AIS) was defined as a rapidly developing neurological deficit with an obvious known onset, and an initial CT brain with no proof of ICH.

Description

Inclusion Criteria:

  • First attack of acute MCA territory infarction within 2 days from the onset.

Exclusion Criteria:

  • previous stroke,
  • presence of anterior cerebral artery infarction,
  • posterior cerebral artery infarction, and
  • venous infarction.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Impaired Cognition
First group was cognitively impaired test with MoCA score of 25 or less.
Diagnostic test: Montreal Cognitive Assessment (MoCA)
This scale evaluates different domains of cognition like attention, orientation, memory, language, visuoconstructional capacities, and lastly, executive functions. MoCA is a thirty point test with a score of 25 or less considered as abnormal impaired cognition
Preserved cognition
The second group was cognitively preserved with MoCA score of higher than 25.
Diagnostic test: Montreal Cognitive Assessment (MoCA)
This scale evaluates different domains of cognition like attention, orientation, memory, language, visuoconstructional capacities, and lastly, executive functions. MoCA is a thirty point test with a score of 25 or less considered as abnormal impaired cognition

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Montreal Cognitive Assessment
Time Frame: 3 month after discharge
This scale evaluates different domains of cognition like attention, orientation, memory, language, visuoconstructional capacities, and lastly, executive functions. MoCA is a thirty point test with a score of 25 or less considered as abnormal impaired cognition
3 month after discharge
Assessment of CT brain was done by ASPECTS.
Time Frame: 7 days
The ASPECTS scoring was calculated for all patients. CT brain images were assessed for proof of localized parenchymal hypo-attenuation, loss of differentiation between gray and white matter, and if there is effacement of sulci. ASPECTS gives reliable methods for evaluation of ischemic stroke by utilizing a ten-point score "M1, M2, M3, M4, M5, M6, I: insula, IC: internal capsule, L: lentiform, and C: caudate" everyone represents one point. A Score of 10 means a normal CT scan. One point is decreased for each affected area on the CT brain. So, a score of 0 indicates widespread ischemia affecting the MCA territory
