Multi-infarct dementia results from a series of small strokes affecting several brain regions. Stroke-related dementia involving successive small strokes causes a more gradual decline in cognition. [4] Dementia may occur when neurodegenerative and cerebrovascular pathologies are mixed, as in susceptible elderly people (75 years and older).
Dementia is a devastating disease that impacts one in 10 older Americans. But while many people want to avoid developing dementia, the exact causes of the condition have remained largely a mystery ...
Regarding incidence, cohort longitudinal studies (studies where a disease-free population is followed over the years) provide rates between 10 and 15 per thousand person-years for all dementias and 5–8 for AD, [236] [237] which means that half of new dementia cases each year are Alzheimer's disease. Advancing age is a primary risk factor for ...

The existence of alcohol-related dementia is widely acknowledged but not often used as a diagnosis, due to a lack of widely accepted, non-subjective diagnostic criteria; more research is needed. [10] Criteria for alcohol-induced persistent dementia in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) include the following: A.
Early onset dementia is less common than late onset dementia, the former accounting for approximately 10% of dementias globally. [3] Recent studies estimate the prevalence of early onset dementia to be approximately 3.55 million people aged 30–64 worldwide, and will triple by 2050. [6] with an incidence of 119 per 100,000 individuals. [1]
Childhood dementia is very often diagnosed late, misdiagnosed, or not diagnosed at all. [9] A correct diagnosis happens, on average, 2 years or more after symptoms become apparent. Additionally, children affected by childhood dementia are often misdiagnosed with: Autism [16] [9] [17] Developmental or intellectual delay [16] [9] ADHD [9] Others [9]
A dementia diagnosis is made after cognitive decline progresses to a point of interfering with normal daily activities, or social or occupational function. [25] While dementia is an essential feature of DLB, it does not always appear early on, and is more likely to be present as the condition progresses. [25] [26]
