Decision levels of diabetes mellitus and hyperlipidemia in elderly subjects as well as younger subjects should be determined to prevent complications of these diseases such as microvascular and macrovascular diseases. Therefore, prospective follow-up study is necessary to decide the decision levels. In the case of diabetes mellitus, there are some useful studies such as KUMAMOTO STUDY show that strict glycemic control can prevent microvascular diseases, but there are few studies in elderly subjects. However, hypoglycemia causes macrovascular events, and chronic hypoglycemia leads to dementia and apathy. It is generally accepted that the glycemic control level can be milder than that in younger subjects. We suggest that the following decision levels are reasonable for elderly diabetic subjects, 1. FPG > 140-160 mg/dl, 2. PG(2 h) > 200-250 mg/dl, 3. HbA1c > 7-8%. Decision level of hyperlipidemia in elderly subjects should also be determined to prevent cardiovascular disease. It is demonstrated that anti-hyperlipidemic treatment can prevent CHD even in elderly subjects by many prospective studies. Japan Atherosclerosis Society recommend that the decision levels of hyperlipidemia in elderly subjects can be the same as younger subjects. The decision levels indicating diet therapy and medication for risk factor free subjects(category A) are LDL-C > or = 140 and 160 mg/dl, respectively. Those for subjects without CHD but have some risk factors(category B) are LDL-C > or = 120 and 140 mg/dl, respectively. Those for subjects with CHD(category C) are LDL-C > or = 100 and 120 mg/dl, respectively.

Hyperlipidemia and the atherosclerotic conditions that result from it are well recognized as major contributors to coronary heart disease (CHD). Fortunately, several large-scale clinical trials have shown that there are effective treatments that can substantially lower atherogenic lipid levels and thereby reduce the risk of CHD mortality and morbidity. However, duplication of these dramatic trial results can be negatively affected in "real life" clinical practice by an important issue: compliance. No medications will work if patients do not take them. Unfortunately, patients who need lipid-lowering therapy are likely to need it long-term, perhaps for a lifetime. Yet, many do not adhere to the prescribed medication regimen. This article reviews some major studies of compliance for lipid-lowering drugs. The reasons why patients do not take them as prescribed vary: poor education, lack of understanding, cost, provider indifference, and others. Achieving compliance requires a multifaceted approach. It can be enhanced by encouraging patients to talk openly about their medication habits and by convincing them of the long-term benefits of reaching and maintaining target low-density lipoprotein cholesterol levels. Although more studies focusing on compliance specifically regarding CHD are needed, the current literature does provide some guidance. Arch Fam Med. 2000;9:1169-1175

We report a case of a right-handed, 73-year-old woman with auditory hallucinations lateralized to the right ear. A brain MRI revealed a small infarction in the left dorsomedial nucleus (DM) of the thalamus. The patient did not have either psychiatric or neurological prior history, and had otherwise been treated for ischemic heart disease, hypertension, and hyperlipidemia for 10 years. Two months prior to admission, she had become forgetful, and had lost her wallet several times. She concurrently began to experience auditory hallucinations in which she heard the voices of her acquaintances, or "the gods". She frequently monologized and wandered about outside following the contents of the hallucinations. Therefore, she was admitted to our institution. On admission, no apparent abnormalities were revealed by physical examinations or blood analyses. She was alert and had no aphasic symptoms. Except for memory disturbances, no neurological symptoms, including no hearing loss, were found. A brain MRI showed a small localized infarction in the left DM, but EEG findings were normal. The patient had prominent anterograde memory deficits: she hardly remembered what she had done the very same day, or the names of the doctor and hospital. She also demonstrated a retrograde amnesia of the past decade or two: she showed difficulty recalling either personal history or social events that occurred during this era. Wechsler Adult Intelligence Scale-Revised (WAIS-R) revealed a total IQ of 75 (verbal IQ 77; performance IQ 77). The verbal hallucinations continued with frequent occurrence even after admission. They included voices telling her about misfortunes, such as death or sickness, of her relatives. These turned into threats and commands, such as "I'm gonna kill ya. I attack you from behind. You, do not eat!" In addition, she occasionally experienced "third person auditory hallucination", in which several men were discussing the plan to kill her. As is characteristic of this type of case, the hallucinations always appeared in only her right ear. They did not occur in the other modalities (e.g. as a visual one). She was convinced that the hallucinations were real and looked frightened while they were happening. Whereas the anterograde amnesia continued for 6 months after admission, the retrograde amnesia gradually improved within 2 or 3 months after admission, although a partial amnesia on the past decade eventually turned out to persistent. On the other hand, the hallucinations did not ameliorate satisfactorily with risperidone (3-6 mg/day), but on augmentation with olanzapine (5-20 mg/day), they lessened gradually and almost disappeared within 6 months. She also slowly developed symptoms similar to those of frontal lobe syndrome, i.e., aspontaneity and apathy. In conclusion, our case indicates the importance of DM on memory function. It is noteworthy that schizophrenia-like hallucinations developed in the case. Localized neuronal deficits evoked by infarction in the left DM probably caused the schizophrenia-like hallucinations; the lateralization phenomenon further indicates the involvement of specific neuronal mechanisms in the mediation of the hallucinations. According to the knowledge of the functional anatomy of the DM and the lateralization phenomenon of auditory hallucinations, it is possible that the neuronal loop, comprised of the prefrontal cortex and thalamus, designated as "basal ganglia-thalamocortical circuits", in addition to the left temporal cortex, plays an important role in the development of the hallucinations in this case. This possibility might also shed light on the neurological basis of schizophrenia.

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.

Dementia is a clinical syndrome commonly encountered in clinical practice. Early onset cognitive impairment is always of particular concern and warrants further workup for diagnostic clarity, potentially reversible causes, and prognosis. Unfortunately, although there is increasing knowledge of certain patterns of early onset neurodegenerative disorders, such as early onset Alzheimer's disease and frontotemporal dementia, more atypical cases exist that do not fit these molds. Here, the case is presented of a 67-year-old man who first developed cognitive impairment at age 47 years. He also had a history of hyperlipidemia, hypogonadism, Lyme disease, anxiety, and attention-deficit disorder. He developed executive function deficits, impaired concentration, apathy, and gait disturbance, which led to loss of job, reduction in household responsibilities, and social isolation. He underwent extensive neuropsychiatric workup and several treatment attempts (for Lyme disease and attention-deficit disorder) over the subsequent 20 years; however, he had progressive indolent neurocognitive decline. This workup ruled out known causes of neurodegeneration but was consistent with early onset atypical parkinsonism with dementia of unspecified etiology. This case demonstrates the course of an early onset dementia that, despite exhaustive medical workup, remains diagnostically unclear. This scenario is common across medical specialties, although not often written about. This article synthesizes the individual approaches of neurologists, psychiatrists, radiologists, infectious disease specialists, and psychologists when presented with the same case and the effective multidisciplinary integration of these efforts even when the exact diagnosis remains unknown.
