eWMH Cognitive Health Risk Assessment
Dementia is a degenerative brain syndrome affecting the memory, thinking, behaviour and emotion of sufferers. It causes loss of memory, along with impairments in the sensory system, the person losses control over his or her impulse system and may not remember things and at last stage. In Hong Kong, one in every 10 seniors over 70 years of age suffers from dementia, while it affects about 30% of seniors over 85 years of age. Therefore, it is a significant public health issue.
White matter hyperintensities (WMH) reflects the presence of small vessel disease in brain. Many studies have confirmed that worsening of white matter lesions contributes to brain atrophy and cognitive decline and increases the risk of dementia. WMH can be reverted by approaching a healthier lifestyle. Therefore, if it can be detected and managed at early stage, the risk of becoming dementia should be reduced accordingly.
Automatic Retinal Image Analysis (ARIA) is an artificial intelligence system that can assess the WNH risk through retinal photos and retinal vessels structure analysis. Scientific research show that its accuracy is as high as 90%.¹ Non-invasive, free of side effects, fast and accurate are the main advantages of this system.
