Symptoms of Alzheimer's Disease Early symptoms The earliest symptom of Alzheimer’s Disease is usually short term memory loss. People living with Alzheimer’s Disease will typically forget what they did recently but may remember events from years ago in great detail. This can make people think that there can’t be anything wrong with their memory if they can recall information from so long ago. However it is this loss of short term memory that usually occurs early and which is so characteristic of the onset of Alzheimer’s Disease. If you recognise signs of memory loss in a loved one that keeps on getting worse, to the point you are concerned about it, it is strongly recommended that you make an appointment to see a doctor for an assessment. The earlier that Alzheimer’s Disease is diagnosed, the more can be done to manage it. Difference between early Alzheimer’s Disease and forgetfulnessWe all forget things from time to time and this forgetfulness tends to increase with age. It can be difficult to judge whether this forgetfulness is a part of normal ageing. A person with ‘normal forgetfulness’ can usually still remember other facts associated with the thing they have forgotten. For example, they may briefly forget a person’s name but recognise the person, whereas in early Alzheimer’s Disease someone may not remember they actually know the person at all.
