Alzheimer’s disease operates out of sight – slowly developing over years to cause injury to the brain.3,4 Short-term memory loss, difficulty finding words, and/or losing track of the day or date are typically the first signs of the disease. Other early symptoms include confusion, such as getting lost in familiar places, or changes in mood and personality, for instance becoming more irritable or anxious.1,5 As the disease progresses, people living with AD are slowly being robbed of their memories and the ability to perform everyday activities independently, like cooking, dressing or bathing.1,2
Today, we understand Alzheimer’s disease to be a continuum, as it can be present for decades before it is even suspected. The changes in the brain causing the disease can begin up to 20 years before the first symptoms appear.1-4 Even then, it often goes undetected for far too long. People with AD and their loved ones either overlook early signs of the disease or see them as ‘senior moments’ - just part of getting older.5,6
Alzheimer’s disease starts silently and progresses across several stages. Each person moves through them differently.
