The authors present a 60-year-old patient undergoing periodic hemodialysis who, 3 years after beginning the treatment, developed a clinical picture consisting of disturbances of language, motor dispraxia, loss of memory and concentration, irritability, great change of personality, myoclonias and asterixis. This led progressively to a total loss of motor coordination, including speech. He died 5 months later in a state of dementia, psychosis and incontinence of sphincters. The symptomatology increased after hemodialysis sessions. The normal analytical studies carried out in these cases (electrocardiogram, electromyography, complete roentgenologic study) and also Zn, Cu, and ceruloplasmin measurements were normal. The electroencephalogram showed only a slow tracing with delta waves. Various etiopathogenic possibilities are commented on, as for example alterations in the dialysis water, the use of detergents in cleaning the artificial kidney, a syndrome of imbalance, a decrease in the body potassium and poisoning caused by certain metals such as tin, zinc and aluminium or by drugs which contain benzodiazepine derivatives. The authors conclude that the picture corresponds to a metabolic encephalopathy.

We evaluated in a standard fashion 375 patients presenting with complaints of memory loss. Etiology of memory loss included senile dementia of the Alzheimer type (SDAT)-70%, vascular dementia-5%, mixed dementia (SDAT + vascular)-9%, and other etiologies-16%. Incontinence, transient symptoms, and gait disturbances occurred more frequently in vascular dementia than in SDAT. A history of cardiovascular disease and stroke was more common in vascular dementia than SDAT. Disturbances of gait, bradykinesia, and pyramidal tract findings were commonly seen in vascular dementia. Advanced technology aided diagnosis in only 6% of patients and CT was the most useful of such tests. An earlier age of onset was noted in those with a positive family history of SDAT. Duration of symptoms at presentation for SDAT patients varied inversely with the rate of progression of dementia 15 to 55 months later, suggesting that individuals who progress more slowly require more time to elapse before the family or patient realizes the need for medical attention.

Seven cases of subacute central and peripheral neurologic dysfunction developed in 18 workers employed in the manufacture of reinforced plastic bathtubs. Cases were characterized by weight loss, dizziness, paresthesias, muscle weakness, incontinence, memory loss, and loss of peripheral, color, and night vision. Neuropathies began distally, involved both sensory and motor function, and were associated with prolonged sensory latency, muscle fibrillation, and reduced numbers of functioning motor units. One patient developed posterior lenticular cataracts. Slow improvement occurred on removal from exposure, but residual neuropathies persisted for as long as two years. Epidemiologic investigation disclosed that the first case developed approximately two weeks after introduction of a new plastic foaming agent, 2-t-butylazo-2-hydroxy-5-methylhexane (BHMH). All cases occurred in workers exposed directly to BHMH. No new cases developed after use of BHMH was discontinued. A survey of the firm which produced BHMH and of 68 user firms found two additional clusters of mild neuropathy which may have been caused by BHMH. BHMH was withdrawn from distribution following discovery of these cases. Subsequently, BHMH has been shown in rats to be a potent neurotoxin. Adequate premarket testing could have averted this outbreak.

Posttraumatic hydrocephalus is a treatable complication of head injury and can present with several different clinical syndromes. These include obtundation; simple failure to improve; a tetrad of psychomotor retardation, memory loss, gait trouble, and incontinence; and unusual symptoms including emotional disorder. Posttraumatic hydrocephalus seems to result from a blockage of cerebrospinal fluid (CSF) flow around the cerebral convexities. When the lumbar CSF pressure is consistently above 180 mm H2O, the hydrocephalus should be treated unless a contraindication to operation exists. Underlying brain injury from the trauma itself, however, may prevent recovery. When the typical symptoms of normal pressure hydrocephalus (NPH) are present, a shunt is also indicated. Decision-making is difficult when the patient has normal pressure, but is too injured to display the symptoms of NPH or has atypical symptoms. Overnight pressure recording, lumboventricular infusion testing, or cisternography may clarify whether a shunt is needed in this situation, but there is still considerable uncertainty about shunt prediction in this setting.

Vascular dementia (VAD) is common, and small vessel disease is one of the most frequent etiologies of the disorder. Lacunar state and Binswanger's disease are the two types of VAD associated with small vessel disease. Lacunar state and Binswanger's disease produce a dementia syndrome with characteristics of subcortical dementia including slowing of information processing, impaired memory, and poor sustained attention. Executive dysfunction includes poor word list generation and verbal fluency (design generation), impaired motor programming with perseveration and impersistence, and difficulty with set shifting. Memory loss in subcortical VAD is characterized by poor retrieval and intact recognition. Apathy is ubiquitous in VAD and depression and psychosis are common. Parkinsonism with prominent gait disturbances in conjunction with pyramidal tract signs, dysarthria, pseudobulbar affect, and incontinence are frequent motor manifestations of VAD with small vessel disease. The lesions of subcortical VAD affect the structures--caudate nucleus, globus pallidus, thalamus-and connecting fibers of frontal--subcortical circuits and produce a clinical syndrome similar to that seen in other subcortical diseases.

Legionella is a frequent etiologic agent in the development of both nosocomial and community acquired pneumonias. Involvement of the nervous system is common in Legionella infections. We present a case of Legionnaires' disease which illustrates distinctive neurologic findings including delirium and cerebellar dysfunction. Furthermore, this paper reviews the neurological and psychiatric features of 609 Legionella infected patients with involvement of the nervous system. The most common signs were disorientation (58%), headache (52.4%), and somnolence (39.7%). Less frequent or rare were: cerebellar dysfunction (11.2%), hallucinations (8.4%), agitation or stupor (4.1%), affective disorders (3.1%), peripheral neuropathy (2.8%), pyramidal disturbances (2.1%), memory loss (1.6%), seizures (1.5%), cranial nerve palsies (1.5%), incontinence (0.7%), and extrapyramidal disturbances (0.3%). Cranial CT scans, cerebrospinal fluid findings, and nerve and muscle biopsies were usually unremarkable. Neuropathologic examinations failed to demonstrate specific characteristics. Hyponatremia and serum CPK level elevation were present in up to 89% and 50% of patients, respectively. Prognosis of disturbances of the nervous system was mainly good. We conclude that in the presence of definite neurological findings, pulmonary infection, hyponatremia, and CPK elevation Legionella infection should be considered.

Evidence of poor performance in the evaluation and management of common geriatric conditions suggests the need for changing physician behavior in these areas. Traditional lecture-style continuing medical education (CME) has not been shown to be effective. Expert faculty initially trained 60 nonexpert peer educators to conduct small-group, learner-centered CME using tool kits on memory loss, incontinence, and depression. Peer educators presented 109 community-based sessions to 1,309 medical practitioners. Surveys were administered to community participants immediately and 6 months after a session. Evidence of effectiveness included statistically significant increases in self-reported knowledge, attitudes, and office-based practices on the target topics at the time of training and at the 6-month follow-up (P<.001) and two-thirds of respondents reporting continued use of three or more tools at 6 months. Participants reported that the interactive presentation aided their understanding of and ability to use the tool kits more than an off-the-shelf review (mean rating+/-standard deviation 4.1+/-0.71, with 1 = not at all and 5 = significantly). After the formal evaluation period, additional information about the project dynamics and tool kits was obtained through a small interview sample and an on-line survey, respectively. Receiving copies of the tool kits was an important factor in enabling educators to offer sessions. Barriers to offering sessions included finding time, an audience, and space. Findings suggest that modest positive changes in practice in relation to common geriatric problems can be achieved through peer-led, community-based sessions using principles of knowledge translation and evidence-based tool kits with materials for providers and patients.

Neurological manifestations may complicate Takayasu arteritis (TA) but seizures are rare. A 40-year-old man with TA presented with recurrent episodes of epileptic seizures. Episodes consisted of a brief period of unresponsiveness followed by sudden falling, tonic stiffening and limb jerking. A postictal period with drowsiness, urine incontinence and a temporal loss of memory was also present. A carotid and intracranial duplex ultrasound revealed a reverse flow within the left vertebral artery indicating the presence of subclavian stealing syndrome while extracranial MRA suggested some stenosis at the origin of the left common carotid artery. The EEG was consistent with epilepsy. Neurological manifestations are secondary to ischemia caused by decreased blood flow in the involved carotid and vertebral arteries. Antiepileptic treatment proved effective and may be considered as a reasonable first approach. The stenotic lesions can be managed successfully with angioplasty but these procedures are associated with a high failure rate and may not be needed.

Authors report a case of a 35-year-old male with right-sided mild paresis, incontinence, dysexecutive syndrome, short-term memory loss and behavioral changes. Bilateral cerebral infarcts in the region of the caudate nuclei and the adjacent white matter were proved by brain MRI and multiple stenoses of the branches of Willis-circle were confirmed by MR angiography. Elevated protein level and pleocytosis were found in the cerebrospinal fluid with intrathecal IgG synthesis. Serum rapid plasma reagin, Treponema pallidum Particle Agglutination test, Treponema pallidum ELISA, liquor Venereal Disease Research Laboratory tests were positive. Meningovascular neurosyphilis was diagnosed. 24M U/day intravenous penicillin-G treatment was given for 14 days. The patient has vascular dementia due to the bilateral strategic infarcts disconnecting the prefrontal circuits; his symptoms are similar to general paresis. Laboratory and radiologic improvement was observed. Still, the patient have severe residual cognitive decline.

Caregivers of adults with an intellectual disability experience depressive symptoms, but the aging factors of the care recipients associated with the depressive symptoms are unknown. The objective of this study was to analyze the onset aging conditions of adults with an intellectual disability that associated with the depression scores of their primary caregivers. A cross-sectional survey was administered to gather information from 455 caregivers of adults with an intellectual disability about their symptoms of depression which assessed by a 9-item Patient Health Questionnaire (PHQ-9). The 12 aging conditions of adults with an intellectual disability include physical and mental health. The results indicate that 78% of adults with an intellectual disability demonstrate aging conditions. Physical conditions associated with aging include hearing decline (66.3%), vision decline (63.6%), incontinence (44%), articulation and bone degeneration (57.9%), teeth loss (80.4), physical strength decline (81.2%), sense of taste and smell decline (52.8%), and accompanied chronic illnesses (74.6%). Mental conditions associated with aging include memory loss (77%), language ability deterioration (74.4%), poor sleep quality (74.2%), and easy onset of depression and sadness (50.3%). Aging conditions of adults with an intellectual disability (p<0.001) was one factor that significantly affected the presence of depressive symptom among caregivers after controlling demographic characteristics. Particularly, poor sleep quality of adults with an intellectual disability (yes vs. no, OR=3.807, p=0.002) was statistically correlated to the occurrence of significant depressive symptoms among their caregivers. This study suggests that the authorities should reorient community services and future policies toward the needs of family caregivers to decrease the burdens associated with caregiving.
