O1-12-04: Retinal microvascular changes in vascular cognitive impairment compared to ischemic stroke

ASSOCIATION OF P300 VALUE WITH MOCA-INA IN VASCULAR COGNITIVE IMPAIRMENT POST-ISCHEMIC STROKE PATIENTSABSTRACTIntroduction: Stroke is a major threat in human life because it can cause disability and mortality. Cognitive impairment in early stroke is strong predictor for long term vascular cognitive impairment while neuropsychology method is superior than conventional method to diagnose cognitive impairment, especially P300.Aim: To identify the association between P300 values and MoCA-Ina in vascular cognitive impairment post ischemic stroke patients.Methods: It is a cross sectional design study for ischemic stroke patients who suffered from vascular cognitive impairment during April to June 2018 in Neurology Clinic of Dr. Wahidin Sudirohusodo Hospital, Makassar. The statistical analysis was performed by Pearson’s correlation test.Result: There were 20 samples, male (60%) and female (40%). The average MoCA-Ina score was 19.35±6.06; the average P300 latency in Fz, Cz, and Pz were 370.22±49.01ms, 360.78±38.27ms, and 361.02±44.45ms, respectively; the average P300 in Fz, Cz, and Pz amplitude were 6.09±3.10µV, 5.67±3.49µV, and 6.10±2.77µV, respectively. The Pearson’s showed that P300 latency had significantly correlation with MoCA-Ina score while no correlation between the P300 amplitude and MoCA-Ina.Discussion: There was correlation between P300 latency with MoCA-Ina in vascular cognitive impairment post ischemic stroke patients.Keywords: Ischemic stroke, MoCA-Ina, P300 value, vascular cognitive impairment.ABSTRAKPendahuluan: Stroke merupakan suatu ancaman terbesar di kehidupan manusia karena dapat menimbulkan kecacatan dan kematian. Gangguan kognitif pada awal stroke merupakan prediktor kuat untuk gangguan kognitif vaskular jangka panjang dan metode neuropsikologi lebih unggul daripada metode konvensional untuk mendiagnosis gangguan kognitif, terutama P300.Tujuan: Untuk mengetahui hubungan nilai P300 dengan MoCA-Ina pada pasien gangguan kognitif vaskular pascastroke iskemik.Metode: Desain studi potong lintang terhadap pasien stroke iskemik yang mengalami gangguan kognitif vaskular selama bulan April sampai Juni 2018 di Poliklinik Saraf RSUP Dr. Wahidin Sudirohusodo, Makassar. Data diolah menggunakan uji korelasi Pearson’s.Hasil: Didapatkan 20 orang sampel laki-laki (60%) dan perempuan (40%). Nilai MoCA-Ina rata-rata 19,35±6,06; hasil rata-rata latensi gelombang P300 di Fz, Cz, dan Pz masing-masing adalah 370,22±49,01, 360,78±38,27, dan 361,02±44,45; rata-rata tinggi amplitudo P300 di Fz masing-masing adalah 6,09±3,10, 5,67±3,49, dan 6,10±2,77. Hasil uji korelasi Pearson’s menunjukkan latensi P300 berkorelasi signifikan terhadap MoCA-Ina, sedangkan amplitudo P300 tidak.Pembahasan: Ada hubungan antara latensi gelombang P300 dengan MoCA-Ina pada pasien gangguan kognitif vaskular pascastroke iskemik.Kata kunci: Gangguan kognitif vaskular, MoCA-Ina, nilai P300, stroke iskemik

ABSTRACTBackground:The Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) were compared with and without the addition of a brief processing speed test, the symbol digit modalities test (SDMT), for vascular cognitive impairment (VCI) screening at three to six months after stroke.Methods:Patients with ischemic stroke and transient ischemic attack were assessed with MoCA and MMSE, as well as a formal neuropsychological battery three to six months after stroke. VCI was defined by impairment in any cognitive domain on neuropsychological testing. The area under the receiver operating characteristic curve (AUC) was used to compare test discriminatory ability.Results:One hundred and eighty-nine patients out of 327 (58%) had VCI, of whom 180 (95%) had vascular mild cognitive impairment (VaMCI), and nine (5%) had dementia. The overall AUCs of the MoCA and MMSE scores and performance at their respective cut-off points were equivalent in detecting VCI (AUCs: 0.87 (95% CI 0.83–0.91) vs. 0.84 (95% CI 0.80–0.88), p = 0.13; cut-offs: MoCA (≤23) vs. MMSE (≤26), sensitivity: 0.78 vs. 0.71; specificity: 0.80 vs. 0.82; positive predictive value: 0.84 vs. 0.84; negative predictive value: 0.72 vs. 0.67; and correctly classified 78.6% vs. 75.5%; p = 0.42). The AUCs of MMSE and MoCA were improved significantly by the SDMT (AUCs: MMSE+SDMT 0.90 (95% CI 0.87–0.93), p <0.001; MoCA+SDMT 0.91 (95% CI 0.88–0.94), p < 0.02).Conclusions:The MoCA and MMSE are equivalent and moderately sensitive, and can be supplemented with the SDMT to improve their accuracy in VCI screening.
