Association between the outcome of traumatic brain injury patients and cerebrovascular autoregulation, cerebral perfusion pressure, age, and injury grades.

Background And Objective: The aim of this study was to explore the association of cerebrovascular autoregulation (CA) and optimal cerebral perfusion pressure (CPP) managing conditions with the outcome of traumatic brain injury (TBI) patients including additional information about the patients' age and grade of diffuse axonal injury (DAI).

Materials And Methods: The CA monitoring of 28 TBI patients was performed by using ICM+ software (Cambridge, UK). The CA status estimating pressure reactivity indexes (PRx) and CPP data were processed in order to obtain information on the patient-specific treatment conditions by calculating the optimal CPP.

Association of Severe Traumatic Brain Injury Patient Outcomes With Duration of Cerebrovascular Autoregulation Impairment Events.

Background: Cerebrovascular autoregulation (CA) is an important hemodynamic mechanism that protects the brain against inappropriate fluctuations in cerebral blood flow in the face of changing cerebral perfusion pressure. Temporal CA failure is associated with worse outcomes in various acute neurological diseases. An integrative approach is presently used according to the existing paradigm for the association of series of temporal CA impairments with the outcomes of patients with traumatic brain injury (TBI).

Cognitive Results of CANTAB Tests and Their Change Due to the First Dose of Donepezil May Predict Treatment Efficacy in Alzheimer Disease.

BACKGROUND Ability to predict the efficacy of treatment in Alzheimer disease (AD) may be very useful in clinical practice. Cognitive predictors should be investigated alongside with the demographic, genetic, and other predictors of treatment efficacy. The aim of this study was to establish whether the baseline measures of CANTAB tests and their changes due to the first donepezil dose are able to predict the efficacy of treatment after 4 months of therapy.

The BICAMS Battery for Assessment of Lithuanian-Speaking Multiple Sclerosis Patients: Relationship with Age, Education, Disease Disability, and Duration.

BACKGROUND Assessment of cognitive impairment (CI) in multiple sclerosis (MS) patients is very useful, but it requires time-consuming expert evaluation with specialized materials. The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) was created as a brief and specific instrument for the evaluation of CI. The aims of this study were to assess the cognitive status of MS patients by using the Lithuanian version of BICAMS, to evaluate the test-retest reliability of the Lithuanian version of BICAMS, and to measure the impact of CI on disability and duration of MS.

Selective Ability of Some CANTAB Battery Test Measures to Detect Cognitive Response to a Single Dose of Donepezil in Alzheimer Disease.

Background: The Cambridge Neuropsychological Test Automated Battery (CANTAB) was used to explore which tests and their measures are able to detect cognitive change after a single dose of donepezil in Alzheimer disease (AD) patients. The aim of this study was to establish the ability of CANTAB tests and their measures to detect cognitive change after a single 5-mg dose of donepezil in treatment-naïve AD patients.

Material And Methods: We enrolled 62 treatment-naïve AD patients and 30 healthy controls in this prospective, randomized, rater-blinded study.

Distinctive Effect of Donepezil Treatment on P300 and N200 Subcomponents of Auditory Event-Related Evoked Potentials in Alzheimer Disease Patients.

Background: Latency of P300 subcomponent of event-related potentials (ERPs) increases in Alzheimer disease (AD) patients, which correlate well with cognitive impairment. Cholinesterase inhibitors (ChEIs) reduce P300 latency in AD patients with parallel improvement in cognition. It is not known whether N200 response to ChEIs is similar to that of P300.

Therapeutic Plasma Exchange in Multiple Sclerosis Patients with Abolished Interferon-beta Bioavailability.

Background: Neutralizing antibodies (NAb) to interferon-beta (IFN-β) are associated with reduced bioactivity and efficacy of IFN-β in multiple sclerosis (MS). The myxovirus resistance protein A (MxA) gene expression is one of the most appropriate markers of biological activity of exogenous IFN-β. We hypothesized that therapeutic plasma exchange (TPE) can restore the ability of IFN-β to induce the MxA mRNA expression and that maintenance plasmapheresis can sustain the bioavailability of IFN-β.

Differential diagnosis of depression and Alzheimer's disease with the Addenbrooke's Cognitive Examination-Revised (ACE-R).

Background: One of the usual problems psychologists and clinicians face in clinical practice is differential diagnostics of Alzheimer's disease and depression. It has been reported that the ACE and ACE-R could discriminate the cognitive dysfunctions due to depression from that due to dementia, although this is not uniform in all studies. The current study aimed to evaluate the utility of the ACE-R to differentiate late-life onset depression (with severe episode) from mild-moderate Alzheimer's Disease (AD).

People with epilepsy lack knowledge about their disease.

For people with epilepsy, knowledge of their disease is an important factor in optimizing the control of their seizures. Better-informed patients can more easily participate in the treatment process, reducing disease-related anxiety and coping better with stigma. This study was developed in a Lithuanian tertiary epilepsy center to assess knowledge of disease among people with epilepsy, to estimate differences in disease knowledge between patient groups, and to evaluate how epilepsy influences patients' daily lives.

Safety and efficacy of adjunctive lacosamide among patients with partial-onset seizures in a long-term open-label extension trial of up to 8 years.

Long-term (up to 8 years of exposure) safety and efficacy of the antiepileptic drug lacosamide was evaluated in this open-label extension trial (SP615 [ClinicalTrials.gov identifier: NCT00552305]). Patients were enrolled following participation in a double-blind trial or one of two open-label trials of adjunctive lacosamide for partial-onset seizures.

[Results of carotid endarterectomy in diabetic patients].

Unlabelled: Patients with diabetes mellitus have been shown to have an increased incidence of complications after major vascular surgery. The objective of this study was to evaluate the results of carotid endarterectomy in diabetic patients, to determine if results differ from nondiabetic patients, and to examine the risk factors for poor outcome among diabetic patients.

Material And Methods: We reviewed all carotid endarterectomies performed in Emergency Hospital of Vilnius University.

[Carotid artery atherosclerotic stenosis, plaque structure and stroke].

Objectives: The main indication for carotid endarterectomy is severity of stenosis carotid artery. Several studies have shown the relationship between carotid plaque morphology and cerebrovascular disorders. The purpose of this study was to evaluate the structure of carotid plaque and correlate carotid plague morphology with neurological symptoms, stroke risk factors, severity of carotid stenosis and operative stroke.

Aneurysmal subarachnoid hemorrhage in Baltic population: experience from Latvia (1996-2000).

Better knowledge of clinical epidemiology and course of aneurysmal subarachnoid hemorrhage (ASAH) is essential for dedicated planning of the need for services. The aim of the study was to obtain a picture of epidemiology and clinical course of ASAH in Riga City (the capital of Latvia). A retrospective population-based study included residents of Riga City who suffered their first ASAH during a 5-year period from the beginning of 1996 till the end of 2000.

Somatosensory evoked potential monitoring during intracranial surgery.

In the neurosurgical approach to intracranial aneurysms which are often accompanied by arterial spasm and cortical ischaemia, monitoring procedures aim to obtain useful information on cerebral function. SEPs evoked by stimulation of the median nerve at the wrist and of the tibial nerve at the medial malleolus were registered in 45 patients with intracranial aneurysms during neurosurgical procedures. Our results show SEP abnormalities during different stages of neurosurgical procedures in 36 patients out of the monitored 45.
