Six rabbits were immunized against the pyrrolizidine alkaloid retrorsin, conjugated to bovine
serum albumin
. Seven i.v. inoculations were distributed over a period of half a year. The total antigen dose differed between animals. Towards the end of the experiment all animals (except 2 receiving the lowest antigen dose) suffered from
apathy
, anorexia and loss of body weight. Pathologically these symptoms correlated well with liver cirrhosis, gradually dependent on the total antigen dose. Blood-chemical parameters were disparate and contradictory.

Apathy
is defined as a syndrome of primary loss of motivation not attributable to emotional distress, intellectual impairment or consciousness disturbance. The aim of our study was to investigate the effects of vascular risk factors and silent ischemic brain lesions on apathetic behavior of community-dwelling elderly subjects. Brain MRI and other medical examinations were performed on 222 non-demented community-dwelling elderly subjects (96 men and 126 women, average age 70.1 years). The
apathy
group was defined as the most apathetic quintile determined by Starkstein's
apathy
scale. Silent infarction, deep white matter lesions (DWMLs) and periventricular hyperintensities were detected in 12.2, 39.2 and 22.5%, respectively. Linear regression analysis (Pearson) revealed that the scores on the
apathy
scale correlated slightly but significantly with logarithmically transformed scores of the Modified Stroop Test (r=0.135, P=0.045), but not with the Mini-Mental State Examination. The
apathy
group tended to have more high blood pressure (141.6/82.6 vs. 136.1/79.6 mm Hg), less prevalent hyperlipidemia (18 vs. 35%) and lower
serum albumin
. Multivariate analysis (the forward stepwise method of logistic analysis) revealed an independent correlation between the
apathy
and grade of DWMLs (odds ratio 1.826, 95% confidence interval (CI) 1.129-2.953 per grade) or diastolic blood pressure (DBP) (odds ratio 1.055, 95% CI 1.014-1.098 per mm Hg) after adjusting for possible confounders. The mean
apathy
scale score in the DBP>or=90 mm Hg group was significantly lower (more apathetic) than that in the DBP<80 group (P=0.011, analysis of covariance). This study showed that hypertension and DWMLs are independently associated with
apathy
in healthy elderly subjects.
