==Background==
'''Alzheimer's disease''' is the most common form of [[dementia]].
 
When a doctor or physician has been notified, and AD is suspected, the diagnosis is usually further supported by behavioral assessments and [[cognitive tests]], often followed by a [[neuroimaging|brain scan]] if available.<ref name="alzres">

}}</ref> Individual [[prognosis]] is difficult to assess, as the duration of the disease varies. AD develops for an indeterminate period of time before becoming fully apparent, and it can progress undiagnosed for years. The mean life expectancy following diagnosis is approximately seven years.<ref name="pmid3776457">{{cite journal

Currently-used treatments offer a small symptomatic benefit.  No treatments to halt the progression of the disease are yet available. As of 2010, more than 700 [[clinical trials]] were investigating possible treatments for AD, but it is unknown if any of them will prove successful.<ref>{{cite web

}}</ref> Many measures have been suggested for the [[preventive medicine|prevention]] of Alzheimer's disease, but the value of these measures is unproven in slowing the course and reducing the severity of the disease. Mental stimulation, [[exercise]], and a [[balanced diet]] are often recommended as both a possible prevention and a sensible way of managing the disease.<ref name="prevention1">

Because AD cannot be cured, management of patients is essential as the disease progresses. The role of the main caregiver is often taken by a spouse or a close relative.<ref name="metlife.com">{{cite web
