Dementia is an umbrella term for a range of progressive conditions that affect the brain. There are over 200 subtypes of dementia, but the five most common are: Alzheimer’s disease, vascular dementia, dementia with Lewy bodies, frontotemporal dementia and mixed dementia. The brain is made up of nerve cells (neurones) that communicate.
What is dementia?
INTRODUCTION Dementia is a clinical diagnosis requiring new functional dependence on the basis of progressive cognitive decline and representing, as its Latin origins suggest, a departure from previous mental functioning. The incidence of dementia rises with age making it an increasingly common phenomenon within our aging population.
Introduction Approximately 50 million people worldwide have dementia, and it is projected to almost triple by 2050 (1).
An adequate medical and societal response to dementia in the UK has implications for medical training and workforce planning, the support of carers, institutional care, and of course for research into treatments aimed at halting disease progression. In this issue we look at dementia from a number of primary care angles.

Attention-deficit/hyperactivity disorder (ADHD) is associated with poor grades, poor reading and math standardized test scores, and increased grade retention.
What is ADHD (Attention Deficit Hyperactivity Disorder)?

What is Alzheimer’s disease?
Alzheimer’s disease AD is the most common neurodegenerative disease responsible for dementia, comprising 60% to 80% of cases.
What is the history of Alzheimer’s disease research?
During the 1980s our field began its foundational studies of profiling the neuropsychological deficits associated with AD and its differentiation from other dementias (e. g, cortical vs. subcortical dementias). The 1990s continued these efforts and began to identify the specific cognitive mechanisms affected by various neuropathologic substrates.
What are the characteristics of Alzheimer’s disease?
Abstract The characteristic features of Alzheimer’s disease (AD) are the appearance of extracellular amyloid-beta (Aβ) plaques and neurofibrillary tangles in the intracellular environment, neuronal death and the loss of synapses, all of which contribute to cognitive decline in a progressive manner.
What are the Hallmark pathologies of Alzheimer’s disease?
This neurodegenerative disease process is characterized classically by two hallmark pathologies: β-amyloid plaque deposition and neurofibrillary tangles of hyperphosphorylated tau. Diagnosis is based upon clinical presentation fulfilling several criteria as well as fluid and imaging biomarkers.
