Eurek Alert: Have you ever been shopping and returned home to find that you have forgotten to buy the very item you went shopping for? Have you known it was going to rain yet left your umbrella at home? Have you gone out and left the television on?
All these instances are examples where prospective memory has failed – you have not remembered to take the action you had planned. While these examples are comparatively trivial, poor prospective memory can have serious consequences – forgetting to take medication, or leaving the stove on, for example.
A failing prospective memory can be an early sign of Alzheimer’s disease, according to University of Chichester psychologists, and new therapeutic methods are being used to utilise levels of prospective memory as a means to accurately diagnose diseases of cognitive impairment. Such methods can be effective non-invasive alternatives to traditional clinical methods such as the extraction of cerebral spinal fluid.
In research published in the journal “Neuropsychology”, a team led by the University of Chichester has studied prospective memory performance of 96 participants including patients with mild cognitive impairment aged 64 to 87 years, healthy older adults aged 62 to 84 years and younger adults aged 18 to 22 years.
