The 2022 symposium on dementia and brain aging in low- and middle-income countries: Highlights on research, diagnosis, care, and impact.

Two of every three persons living with dementia reside in low- and middle-income countries (LMICs). The projected increase in global dementia rates is expected to affect LMICs disproportionately. However, the majority of global dementia care costs occur in high-income countries (HICs), with dementia research predominantly focusing on HICs.

Pathology-supported genetic testing as a method for disability prevention in multiple sclerosis (MS). Part II. Insights from two MS cases.

In Part I of this Review we evaluated the scientific evidence for a Metabolic Model of multiple sclerosis (MS). Part II outlines the implementation of an adaptive pathology-supported genetic testing (PSGT) algorithm aimed at preventing/reversing disability in two illustrative MS cases, starting with a questionnaire-based risk assessment, including family history and lifestyle factors. Measurement of iron, vitamin B12, vitamin D, cholesterol and homocysteine levels identified biochemical deficits in both cases.

A clinical profile of inpatient admissions to the psychogeriatric unit at Stikland Hospital.

Background: Globally, the number of older people is rising. As a consequence of greater longevity, an increased burden on both medical and mental health care is expected. As a first step towards developing strategies to provide quality mental health care for this growing population, practitioners need to have a thorough understanding of the composition and needs of these patients.

Memantine and functional communication in Alzheimer's disease: results of a 12-week, international, randomized clinical trial.

Post hoc analyses suggest that memantine treatment may provide communication-related benefits in patients with Alzheimer's disease (AD). In this 12-week, international, randomized, double-blind, placebo-controlled trial of memantine (10 mg bid), the functional communication abilities of patients with AD (MMSE range: 10-19) were assessed using the Functional Linguistic Communication Inventory (FLCI; primary measure). Two combined subscales (Social Communication and Communication of Basic Needs) from the American Speech-Language-Hearing Association Functional Assessment of Communication Skills for Adults (ASHA FACS; secondary measure) were administered to caregivers.

FUS and TDP43 genetic variability in FTD and CBS.

This study aimed to evaluate genetic variability in the FUS and TDP-43 genes, known to be mainly associated with amyotrophic lateral sclerosis (ALS), in patients with the diagnoses of frontotemporal lobar degeneration (FTLD) and corticobasal syndrome (CBS). We screened the DNA of 228 patients for all the exons and flanking introns of FUS and TDP-43 genes. We identified 2 novel heterozygous missense mutations in FUS: P106L (g.

Alzheimer's disease and vascular dementia in developing countries: prevalence, management, and risk factors.

Despite mortality due to communicable diseases, poverty, and human conflicts, dementia incidence is destined to increase in the developing world in tandem with the ageing population. Current data from developing countries suggest that age-adjusted dementia prevalence estimates in 65 year olds are high (>or=5%) in certain Asian and Latin American countries, but consistently low (1-3%) in India and sub-Saharan Africa; Alzheimer's disease accounts for 60% whereas vascular dementia accounts for approximately 30% of the prevalence. Early-onset familial forms of dementia with single-gene defects occur in Latin America, Asia, and Africa.

Genetic variability in CHMP2B and frontotemporal dementia.

A nonsense/protein chain-terminating mutation in the CHMP2B gene has recently been reported as a cause of frontotemporal dementia (FTD) in the single large family known to show linkage to chromosome 3. Screening for mutations in this gene in a large series of FTD families and individual patients led to the identification of a protein-truncating mutation in 2 unaffected members of an Afrikaner family with FTD, but not in their affected relatives. The putative pathogenicity of CHMP2B mutations for dementia is discussed.

Galantamine prolonged-release formulation in the treatment of mild to moderate Alzheimer's disease.

The primary objective of this study was to evaluate the efficacy and tolerability of a flexible dosing regimen (16 or 24 mg/day) of galantamine prolonged-release capsule (PRC) compared with placebo in subjects with mild to moderate Alzheimer's disease (AD). This phase III, double-blind, placebo- and active-controlled, parallel-group trial randomized 971 patients to treatment for 6 months. Efficacy endpoints included change in the 11-item cognitive subscale of the Alzheimer's Disease Assessment Scale (ADAS-cog/11), Clinician's Interview-Based Impression of Change plus caregiver input (CIBIC-plus), Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL), and Neuropsychiatric Inventory (NPI) scores.

Biochemical model for inflammation of the brain: the effect of iron and transferrin on monocytes and lipid peroxidation.

Cerebral inflammation plays a role in diseases such as multiple sclerosis (MS), Alzheimer's disease (AD), and depression. Iron is involved in infection and inflammation through free radical production. Theoretically transferrin should prohibit iron from participating in oxidative reactions, but transferrin has also been found to promote free radical damage.

5- and 6-glycosylation of transferrin in patients with Alzheimer's disease.

Transferrin is a glycosylated metal-carrying serum protein. One of the biological functions of glycosylation is to regulate the life span of proteins, less glycosylation leading to a faster clearance of a protein from the circulation. In the case of transferrin, this would indirectly also influence iron homeostasis.
