Abstract P55: Retinal Microvascular Parameters Predict Retinal Amyloid Burden and Co-Jointly Predict Verbal Memory

Introduction: Retinal vascular features predict cognitive performance and retinal imaging is a non-invasive tool to study brain health. Patients with Alzheimer’s disease (AD)-related cognitive disorders exhibit both retinal vascular abnormalities and intraretinal accumulation of amyloid-beta (Aβ) plaque. Curcumin-enhanced retinal fluorescence imaging (CRFI) was recently translated as a safe imaging tool for retinal Aβ plaque quantification. In this study, we sought to determine whether and which retinal arterial and venous parameters are predictive of retinal Aβ burden and cognitive Z-scores.

Methods: We used scanning laser ophthalmoscopy with RetiaTM (Centervue, Inc) to obtain CRFI in a cohort of patients with cognitive decline. Retinal blood vessels were segmented in a predefined circumpapillary region of interest. For each centerline, vessel tortuosity index (VTI), vessel inflection index (VII), and branching angle (VBA) were quantified, independently for arteries and veins. Additionally, we automatically quantified retinal amyloid count in the supero-temporal quadrant and its subregions: posterior pole (PP), proximal mid-periphery (PMP), and distal mid-periphery (DMP). All quantifications were done blinded to the subjects’ clinical characteristics. Linear regression models were used to assess the correlations between retinal vascular and amyloid parameters.

Results: 29 subjects (55% female, mean age 64±6 years) were included in the analysis: 11 had normal cognition, 16 mild cognitive impairment and 2 probable AD. Venous VTI was the only vascular parameter significantly different across levels of Clinical Dementia Rate scores and between cognitively normal and impaired. Venous VBA was a significant predictor of DMP amyloid count (p=0.03). Arterial VII significantly predicted PP amyloid count (p=0.02). VBA predicted Wechsler Adult Intelligence Scale Z-score (p=0.08). The combined VTI-PMP amyloid index significantly predicted Wechsler Memory Scale, California Verbal Learning Test and SF-36 mental component score Z-scores (p<0.05).

Conclusion: Retinal venous tortuosity discriminates across cognitive scores and in combination with PMP amyloid count may predict verbal memory and related quality-of-life scores.

Comparison of mental status in mothers and wives of addicted men, with mothers and wives of non-addicted men

Introduction

Substance abuse of main family member can affect other family members in some studies.

Aims

Comparing the mental status of mothers and wives of addicted men, with mothers and wives of non-addicted men.

Methods

In a case-control study which performed in a recovery home in Arak-Iran, In 2009, 57 mothers and wives of addicted men, and 57 mothers and wives of non-addicted men were assessed by MMPI-2 questionnaire. Data were analyzed by using SPSS V17.

Results

The mean scores of addicted men's mothers were significantly higher than non-addicted men's mothers in hypochondriasis, depression, psychopath deviation, paranoia, psychasthenia, schizoid, and F scales. On the other hand, the mean scores of addicted men's wives were significantly higher than non-addicted men's wives in hypochondriasis, psychopath deviation, paranoia, psychasthenia, schizoid, and F scales.

Conclusion

There are severe psychiatric problems in mothers and wives of addicted men.
