A number of early Alzheimer's symptoms can be missed as they appear to be the result of old age.
The disease is one of the most common types of dementia and the earlier it is diagnosed the better for the patient. It can be difficult to realise someone has Alzheimer’s early as many of the symptoms could be put down to factors including depression or stress.
Alzheimer's is a progressive disease, where dementia symptoms gradually worsen over a number of years. In its early stages, memory loss is mild, but with late-stage Alzheimer's, individuals lose the ability to carry on a conversation and respond to their environment.
