"The use of dementia in the literature is heterogeneous, with varying definitions 8. Some authors include both reversible and irreversible causes of cognitive impairment in their definition of dementia, whilst others state that dementia is irreversible 6 and that conditions with reversible causes should not be classified as dementia. Thus, depending on the definition, chronic subdural haematoma and normal pressure hydrocephalus may or may not be included as causes of dementia."
"Young-onset dementia, also known as early-onset dementia and historically as presenile dementia, is a term that can be defined as dementia onset before 65 years (range 60-70 years) 7. Rapidly progressive dementia is a term used to describe a dementia progressing over weeks to months 11."

"depression is most common, but other psychiatric conditions (e.g. mania, psychosis, functional neurological disorder, and malingering) can mimic depression 5,12"
"Given this heterogeneity, it is prudent to use the word dementia increasingly sparingly 10 and probably err on the side of reserving it for the subgroup of conditions that everyone agrees are on the list: irreversible neurodegenerative disease (e.g. Alzheimer disease, frontotemporal lobar degeneration, etc)."
"Each cause of dementia presents with a different constellation of impaired cognitive domains, with the potential for associated neurologic findings depending on the pathophysiology. There is considerable overlap between the resulting clinical syndromes, especially in late disease and in older comorbid patients who may have multiple causes contributing to the presenting dementia syndrome. Indeed, many patients may have multiple dementia-causing pathologies present concurrently."
