Neurodegenerative diseases are the most frequent cause of dementia, representing a burden for public health systems (especially in middle and middle-high income countries). Although most research on this issue is concentrated in first-world centers, growing efforts in South America are affording important breakthroughs. This emerging agenda poses new challenges for the region but also new opportunities for the field. This book aims to integrate the community of experts across the globe and the region, and to establish new challenges and developments for future investigation. We present research focused on neurodegenerative research in South America. We introduce studies assessing the interpl...
With life expectancy on the rise, the proportion of people aged 60 or older is projected to account for more than one-fifth of the global population by 2050. Sleep quality is one of the most common health concerns that increases with age. Changes in sleep patterns associated with old age include disturbed sleep onset, an increase in sleep fragmentation, more frequent daytime dysfunction, and less slow-wave sleep than younger adults. Sleep is a complex physiological process critical to our health and survival; the many functions of sleep range from cerebral metabolic waste clearance and energy conservation to supporting cognitive performance and psychological well-being. Insufficient sleep ha...

Neuroepidemiology in Tropical Health covers major neurological diseases of relevance in tropical settings and examines the specificities of epidemiology of neurological diseases in the context of tropical countries that face many challenges when compared to the developed world. Part One focuses on methods and their eventual specificities, and how such methods, like sampling, can be adapted for specific scenarios. Parts Two and Three discuss environmental factors and their consequences for neurology in the tropical world, as well as large geographical areas and their specificities. Finally, Part Four presents relevant neurological diseases in in-depth chapters. This invaluable information wil...
Frontotemporal lobar degeneration (FTLD) encompasses a spectrum of focal neurodegenerative disorders with progressive atrophy of the frontal and temporal lobes. FTLD-related disorders are heterogeneous clinical conditions characterized by social dysfunction and personality changes as well as impairments in language, executive and motor functions. Current clinical diagnostic criteria characterize specific manifestations of FTLD, including transtemporal behavioral dementia (bvFTD), primary progressive aphasia with agrammatic variant (avPPA) and semantic variant (svPPA) subtypes, and movement disorders, including progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and FTD with amyotrophic lateral sclerosis (FTD-ALS).

Latin American countries are in the midst of a demographic transition and, as a consequence, a population-aging process. Over the next few decades, the number of children will decline relative to the number of older adults. Population aging is the result of a slow but sustained reduction in mortality rates, given increases in life expectancy and fertility. These trends reflect welcome long-term improvements in welfare and in economic and social development. But this process also entails policy challenges: many public institutions—including education, health, and pension systems and labor market regulations—are designed for a different demographic context and will need to be adapted. When...
