Dementia affects over 885,000 people in the UK, reducing quality of life and costing the UK economy over £34 billion per year. People with Mild Cognitive Impairment (MCI) are at higher risk of developing Alzheimer’s Disease (60-80% of all dementia cases), as they represent early stages of dementia.
It is important that people with MCI are screened early as timely detection is critical for effective interventions aimed at improving symptoms, quality of life and future planning. However, not everyone with MCI undergoes a test and is offered a diagnosis. In addition, routine tests of dementia do not focus on the specific cognitive functions that are mediated by the hippocampi which are affected in MCI.
One important cognitive function, supported by the hippocampi, is ‘memory binding’ in which different features of an item (e.g., appearance, names, location) are combined. Memory binding is vital for everyday activities i.e. identifying where (location) one’s keys (object) are, or recalling the names of acquaintances (faces, names). Although the hippocampus has been implicated in early dementia, cognitive functions such as memory binding in visual short-term memory (VSTM) task have not been studied in detail.
More importantly, memory binding as a screening tool for early detection of MCI has not been studied adequately. Our preliminary studies have examined memory binding performance in VTSM tasks on a smaller group (n= ≤36) of young, normal older and MCI participants. Our data show that performance declines with age, and is also affected in people with MCI when compared to age/education-matched controls.
