Psychopathology at initial diagnosis in dementia with Lewy bodies versus Alzheimer disease: comparison of matched groups with autopsy-confirmed diagnoses

Dementia with Lewy Bodies is associated with higher scores on the Geriatric Depression Scale than is Alzheimer's disease

“…In the present study, the GDS scores of DLB patients were twice as high as the scores of AD patients, with significant differences between groups. These results are compatible with those of some earlier studies, 2,3 but not with others 4,5 . Klatka et al 2 .…”

Utility of neuropsychiatric tools in the differential diagnosis of dementia with Lewy bodies and Alzheimer's disease: quantitative and qualitative findings

“…The higher prevalence and persistence of visual hallucinations in DLB compared with AD is in agreement with previous studies (Ballard et al, 1995;2001;Del Ser et al, 2000;Rockwell et al, 2000;Engelborghs et al, 2005;Auning et al, 2011). The earlier onset of visual hallucinations with respect to AD is also consistent with prior studies (Ballard et al, 2001;Auning et al, 2011).…”

“…Visual hallucinations were not only more frequent and more persistent in DLB but they appeared at an earlier stage of dementia and tracked better with the progression of disease as compared with AD. The higher prevalence and persistence of visual hallucinations in DLB compared with AD is in agreement with previous studies (Ballard et al ., 1995; 1996; 2001; Del Ser et al ., 2000; Rockwell et al ., 2000; Engelborghs et al ., 2005; Auning et al ., 2011). The earlier onset of visual hallucinations with respect to AD is also consistent with prior studies (Ballard et al ., 2001; Auning et al ., 2011).…”

“…72% (Ballard et al ., 1999), and 77.5% (Del Ser et al ., 2000)). In addition, other authors have reported no or a poor correlation between the frequency of visual hallucinations and the progression of cognitive impairment in DLB (Ballard et al ., 1999; Del Ser et al ., 2000; Rockwell et al ., 2000; Engelborghs et al ., 2005; Stavitsky et al ., 2006). These differences could be explained by their use of the core feature of visual hallucinations as diagnostic criteria.…”

Behavioural and Psychiatric Symptoms in Patients With Neurodegenerative Diseases

“…The present study found that hallucinations were present in 87% of the DLB group, compared to 37% of the PDD group and 20% of the AD group. For DLB, some studies have indicated that depression is a more common symptom than in AD (Ballard et al, 1999), with Rockwell et al (2000) reporting a prevalence rate of 66%, while others have found no difference between the rates (Ala et al, 1997;McKeith et al, 1996). The present study found a high prevalence of depression among the DLB patients (80%).…”
