Major depression was more common and severe in patients with vascular dementia than in patients with AD. In another study of 288 outpatients with dementia, a prevalence of 7.4% was found with HAM-D, 8% prevalence with the GDS and 6.3% with DSM-IV criteria (Brodaty and Luscombe, 1996).
One symptom alone does not necessarily indicate that a person has Alzheimer's or dementia, says Raj C. Shah, MD, of the Rush Memory Clinic at Rush University Medical Center, in Chicago. (Dementia is chronic loss of cognition, usually affecting memory, and Alzheimerâs causes 50% to 80% of dementia cases.) There are many other causes of memory loss, including vitamin B12 deficiency, and brain, thyroid, kidney, or liver disorders. However, having several other symptoms could be a sign of Alzheimer's disease (AD). Recognizing the signs of dementia can help lead to a quicker diagnosis. Advertisement
