AbstractBackground: Brain volume loss (BVL) has become an important biomarker for neurodegeneration in multiple sclerosis (MS). We investigated whether a fully automatic brain volume analysis can predict cognitive impairments by detailed neuropsychological tests.
Methods: We identified subjects from the prospective Chinese University of Hong Kong Multiple Sclerosis Registry who completed a standardized MRI brain and a 45-minute neuropsychological battery. Brain volume was calculated by the 3D T1 sequence by AccuBrain (www.brainnow.cn), a fully-automated brain segmentation measurement tool. Multiple cognitive impairments was defined as >=3 domain deficits in: verbal learning and memory, processing speed, selective attention, executive function, visual perception, simple auditory attention span, and auditory working memory. A cut-off of less than 5th percentile of brain parenchymal fraction (BPF) of published nomogram was used to define ‘significant’ BVL.
Results: Twenty-six MS subjects (22[85%] females, 23 relapsing MS, 2 clinically isolated syndrome, and 1 secondary progressive MS) were recruited. 18(69%) subjects had significant BVL. The mean age was 35.3+/-9.2 years and median EDSS was 2.75 (interquartile range: 1.00-3.50). Cognitive-impaired subjects (>=3 domains) had lower mean BPF (71.03 vs.72.91, p=0.005). BVL significantly correlated with impaired cognition (r=-0.658, p<0.001). BPF correlated with verbal learning and memory (r=0.421, p=0.032), processing speed (r=0.575, p=0.002), and selective attention (r=0.637, p<0.001). WMH correlated with verbal memory (r=-0.438, p=0.042) and visual perception (r=- 0.611, p=0.003). Hippocampal volume correlated with auditory attention (r=0.425, p=0.03) and auditory working memory (r=0.581, p=0.002).
Discussion: Worsening BVL measured by an automatic tool strongly correlated with multiple cognitive impairments among MS patients.
