What is the average time frame from the time symptoms of dementia
occur until a patient is diagnosed?  Could you site any psychiatric
journal references?

Request for Question Clarification by tutuzdad-ga on 20 Apr 2004 18:11 PDT

Without doing more than a cursory search I would imagine that it
depends on what is causing the dementia in the first place, the age,
gender, general health and lifestyle of the patient, and so on.

Clarification of Question by lina123-ga on 22 Apr 2004 14:28 PDT

Clarification on my question would be someone who has either
Alzheimer's Dementia or possibly even vascular dementia with also
Alzheimer's.  If a patient was diagnosed with either types of dementia
say theroretically on May 1 what is the possibility that the same
symptoms were present 1 or 2 months before?  I know with vascular
dementia it would probably depend on when the patient had a stroke but
suppose there was no actual history of stroke. Suppose the patient had
moderate dementia either Alzheimer's of vascular dementia or both in
December but was also diagnosed before this in May of the same year. 
So my question is what is the possibility that this same patient had
the symptoms in March or April before diagnosis in May?
