2. Short term memory loss
One of the most obvious early warning signs of dementia is an impairment of short term memory.
At first, the loss of short term memory is pretty subtle; for instance, the person may be able to very clearly remember something that happened a few years ago, but won’t be able to remember where he or she placed a set of keys or the last time he or she ate a meal.
This is because dementia impacts the neurons, which have a direct impact on memory. Over time, memory loss will become more noticeable and more severe.
