Spontaneous intracranial hematoma is not rare, but with bad prognosis, complication in patients on maintenance hemodialysis (HD). Diagnostic difficulties result from a fact that symptoms of acute hematoma such as headaches,, nausea, vomitis, apathy, sleepiness, parestesia and seizures may also suggest dysequilibrium syndrome, dialytic dementia as well as hypertensive encephalopathy. We describe a case of female patient with 20-year interview data of hypertension on HD since 1981 because of end-stage renal failure in a course of chronic glomerulonephritis, who developed spontaneous epi- and subdural hematoma four year ago in 47 age of life. Performed CT examination confirmed diagnosis and on the same day the patient underwent right frontoparietotemporal craniotomy and the hematoma was removed. During postoperative period, HD sessions were performed without heparin. After surgery the patient developed transcient hypertonia, epileptic sizures and left-sided paresis. Currently, 48 months after craniotomy the patient is fully rehabilitated, with normal blood pressure, without epileptic sizures or palsy. Gradually we discontinued anticonvulsans and antihypertensives.

Presenting symptoms of idiopathic intracranial hypertension are known to vary with age. Older children may complain of headache, neck pain, diplopia, intracranial noises, or transient visual obscurations. Younger children may present with apathy or irritability. This report describes three young children with no obvious relevant symptoms in whom papilledema was newly found on routine follow-up eye examination for unrelated problems. At presentation, all had early papilledema with negative cranial neuroimaging studies. All remained apparently asymptomatic, but the papilledema progressed. Sedated lumbar puncture showed elevated cerebrospinal fluid pressure in all three. Two were felt to have truly idiopathic intracranial hypertension, whereas the third had jugular venous obstruction. The papilledema responded to treatment with either acetazolamide or furosemide in all three. An apparent lack of symptoms does not rule out chronic increased intracranial pressure in young children.

Ignorance, apathy, desire to get free advice, investigation and treatment is prevalent in diabetics. Most diabetics (69.63%) are uncontrolled whether on diet, single oral drug or combination of oral drugs or insulin. Ischemic heart disease was commonest complication. Neuritis was present in the one fourth of the followed up cases and was more prevalent in uncontrolled cases. Hypertension increases with the duration of diabetes and was twice more prevalent after duration of more than 5 years. Eye changes were present in about 50% of the people examined. Abnormality increases with the duration of diabetes.

Until recently, there was little empirical data regarding the psychological impact of screening for type 2 diabetes. There is now some progress in this area, as evidenced by emerging population based studies reporting on the effects of screening for type 2 diabetes on perceived health status and well-being. Recent studies from our own and other groups show that the diagnosis type 2 diabetes has no substantial adverse or positive effect on the participants' perceived health status and well-being after notification of the test result. Importantly, screening-detected type 2 diabetes patients beforehand perceive their risk for type 2 diabetes to be low, despite the presence of risk factors, such as obesity, hypertension and a family history, and overall report low levels of diabetes-related symptom distress. Yet, screening-detected type 2 diabetes patients were bothered more by symptoms of hyperglycaemia and fatigue in the first year following diagnosis type 2 diabetes than non-diabetics. On the basis of research to date, we conclude that screening for type 2 diabetes in the general population has no serious psychological side effects. Whether lack of emotional response to screening, is because of unawareness or indifference, needs further investigation. Future studies should be aiming towards a better understanding of how to raise the awareness and understanding of type 2 diabetes and its risk factors in high-risk individuals, while avoiding or minimizing negative effects, such as emotional distress and denial. The growing number of younger people developing type 2 diabetes warrants further research into labeling effects of an early diagnosis.

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.

Deliberate hyperthermia has been used clinically as experimental therapy for neoplastic and infectious diseases. Several case fatalities have occurred with this form of treatment, but most were attributable to systemic complications rather than central nervous system toxicity. Nonetheless, demyelating peripheral neuropathy and neurological symptoms of nausea, delirium, apathy, stupor, and coma have been reported. Temperatures exceeding 40 degrees C cause transient vasoparalysis in humans, resulting in cerebral metabolic uncoupling and loss of pressure-flow autoregulation. These findings may be related to the development of brain edema, intracerebral hemorrhage, and intracranial hypertension observed after prolonged therapeutic hyperthermia. Furthermore, deliberate hyperthermia critically worsens the extent of histopathological damage in animal models of traumatic, ischemic, and hypoxic brain injury. However, it is unknown whether these findings translate to episodes of spontaneous fever in neurologically injured patients. In a clinical setting fever is a strong prognostic marker of a patient's primary degree of neuronal damage, and a causal relation with long-term functional neurological outcome has not been established for most types of brain injury. Furthermore, in the neurosurgical intensive-care unit fever is extremely common whereas antipyretic therapy is only poorly effective. Therefore maintaining strict normothermia may be an impossible goal in many patients. Although there are several physiological arguments for avoiding exogenous hyperthermia in neurologically injured patients, there is no evidence that aggressive attempts at controlling spontaneous fever can improve clinical outcome.

The incidence of depression is higher than that of dementia in the elderly. Unlike depression in other age groups, that in the elderly is characterized by frequent physical complaints, irritation, and delusional tendencies. The treatment of depression in the elderly requires the complex incorporation of psychiatric and gerontological viewpoints. Psychiatrically, difficulty in accepting decreases in psychological and physical functions and solitude is important, as a psychological characteristic, inducing the development of depression. Biochemically, there is an underlying decrease in the function of brain monoaminergic nerve activated, such as by serotonin and noradrenalin. Radiologically, damage to the cerebral white matter and a decrease in the frontal lobe function have been frequently reported. Depression is difficult to differentiate from dementia and is also often complicated by dementia. Since a depressive state often precede Alzheimer's disease, evaluation of cognitive function is also necessary in patients with a depressive state. Although apathy is often observed as a symptom of dementia and tends to be confused with a depressive symptom, caution is necessary because of differences in the treatment method. Gerontologically, depression is one of geriatric syndrome and isa frequently observed in the elderly in the later stage and closely associated with a decrease in activities of daily life. Depression is also closely associated with lifestyle-related diseases, and its incidence is high in the presence of cerebrovascular disease, ischemic heart disease, hypertension, and diabetes mellitus, and conversely, depression is often complicated by lifestyle-related disease. Anxiety and depression are frequently observed in the frail elderly, but few studies on the assessment and appropriate approach for psychological matters. Further studies are necessary. The treatment of depression in the elderly could be classified into 3 stages. In the acute stage, the treatment method is the same as that in other age groups, mainly consisting of physical and psychological rest and medication. The drug of first choice is a selective serotonin re-uptake inhibitors (SSRI). In intractable cases, electroconvulsive therapy (ECT) is recommended. In the chronic stage, the prevention of disuse syndrome is necessary, and activating approaches such as exercise therapy are used. In addition, support for patients with decreased activities of daily living and the establishment of a community-based cooperation system for the prevention of suicides are future areas to be tackled. It is important that concomitant dementia and physical illness are appropriately assessed and treated in all stages.

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.

The term chronic renal failure (CRF) usually means the final stage of chronic kidney disease (CKD) with a decline in glomerular filtration rate (GF) below 0.25 mL/s. CRF is a world-wide serious health and economic issue with an increasing incidence and prevalence. CRF patients are, in comparison to other patients, hospitalized more often and for longer and, despite improvements in care, their quality of life is usually low and morbidity and mortality high. We present an overview of the most important CKD risk factors and the diseases most likely to result in CRF. Diabetic nephropathy, followed by various forms ofischemic renal disease and primary and secondary glomerulopathy, chronic tubulointerstitial nephritis and autosomal dominant polycystic kidney disease are the leading causes of CRF. We provide a brief overview of other disease states that may result in renal failure. Clinical manifestations of CRF are discussed, mainly cardiovascular, gastrointestinal, haematological and neurological symptoms. Breathlessness is a consequence of hypervolaemia, metabolic acidosis and anaemia. The disease often presents with symptoms, such as headache and visual disturbances, resulting from arterial hypertension. Gastrointestinal symptoms and fatigue, usually caused by anaemia, are frequent. Platelet dysfunction is manifested as an increased bleeding time. Paradoxically, apart form tendency to abnormal bleeding, CRF also tends to be associated with thromboembolic complications. Patients may experience itching, bone, joint and muscle aches, are more prone to infections. They may suffer from insomnia, concentration disorders and apathy. The signs of peripheral mixed sensory-motor neuropathy include paraesthesia, paresis and restless leg syndrome. However, renal failure may also be oligosymptomatic or asymptomatic. Cardiovascular complications are the most frequent cause of morbidity and mortality of CRF patients.

Frailty is a complex and dynamic condition associated with aging. This condition is characterised by the difficult adaptation of an old subject to new challenges occurring during life. Frailty is supposed to be due to the progressive decrease of physiological reserves and multiorgan and multisystem change. It coincides with a reduced or absent resilience. In general comorbidities like hypertension, heart disease, inflammation and infectious diseases are potential risk factors for and psychophysical decline. The aim of this work is to highlight the importance of impaired cognition as factor predisposing to frailty. The authors are convinced and suggest that the presence of neurobehavioral disturbance like apathy associated to impaired executive function could be the major predisposing factor for frailty and unsuccessful aging. Unfortunately available literature largely underestimates the presence of these factors. Thus to better identify markers of frailty, a good neuropsychological assessment and the evaluation of behavioural disturbances are suggested.
