Cardiovascular risk factors and frontotemporal dementia: a case–control study

Cardiovascular risk factors (CRF) were widely described as related to dementia. There are very few studies regarding this association in FTD. The objective of the study was to compare the frequency of CRF in our population with FTD and controls. 100 consecutive subjects with FTD diagnosis according to Lund-Manchester clinical criteria and 200 controls matched by age and sex were included between January 2003 to February 2007 at the Cognitive and Behavior Unit of Hospital Italiano de Buenos Aires. Clinical evaluation, laboratory tests, brain images (CT/MRI), neuropsychological and neuropsychiatric assessment were performed. Multiple regression analysis was performed to analyze the association in CRF between FTD patients vs. controls. The mean age in FTD was 69.7 ± 0.9 vs. 70.1 ± 0.8 in controls (p 0.12). No difference in gender was observed between cases and controls. No differences were identified between patients and controls regarding hypertension (HTA) (65% vs. 67,3% p 0.44); dyslipidemia (57% vs. 54.7% p 0.74); obesity (39% vs. 27.6% p 0.14) and hypothyroidism (26% vs. 17.1% p 0.1). A significant difference was observed for Diabetes Mellitus (39% vs. 22.6% p 0.001). In our population, Diabetes Mellitus was associated as an independent risk factor for FTD. To our knowledge this is the first report in which CRF were evaluated prospectively in FTD patients. More studies are needed to confirm this finding in larger populations.

ALBA Screening Instrument (ASI): A brief screening tool for Lewy Body Dementia

BACKGROUND Early detection of neurodegenerative diseases is essential for treatment and proper care of these patients. Screening tools available today are effective for several types of dementia. However, there is no one specific for Lewy Body Dementia (LBD). OBJECTIVES The aim of this paper is to present a tool for early detection of LBD, accessible even for non-medical staff. METHODS We stratified subjects (MMSE>20) into four groups: health controls (HC), Mild Cognitive Impairment (MCI), LBD and other dementias (Alzheimer and vascular). All subjects (age range 50-90) were examined with a comprehensive neuropsychological and neuropsychiatric evaluation, as well as neuroimaging to differentiate diagnosis between groups, fulfilling corresponding criteria. Both neurologists and neuropsychologists were blind to the performance on clinical evaluations and ASI, respectively. The sensitivity and specificity of the instrument were determined to differentiate LBD from other groups. RESULTS We evaluated 427 subjects, 91 HC, 140 with MCI and 196 with dementia. In the dementia group, 75 were diagnosed with LBD and 121 with other dementias. ASI total score was 12.7±0.4 for LBD, 2.9±0.2 for HC, 5±0.7 for MCI, and 5.4±2.6 for other causes of dementia. ROC curve analysis showed a sensitivity of 90.7% and a specificity of 93.6% stands, with 9 as the cutoff with better test performance compared against other groups. CONCLUSION ASI is a brief screening tool for LBD with high sensitivity and specificity and useful even for non-medical staff.
