Age at diagnosis in FTD.

<p>(A) Age at diagnosis in FTD cases registered in SveDem 2008–2011. (B) The proportion of FTD cases in each age group in the total FTD cohort (blue bars), compared to those cases diagnosed in specialist centres where investigations included cognitive testing and structural or functional imaging (red bars) and cases that had performed lumbar puncture with CSF analysis (green bars).</p

Age-related incidence in FTD and AD.

<p>The figures show the incidence of FTD (A; blue bars) and AD (B; red bars) in relation to age (years). Values for incidence are given as cases per 100 000 person-years in each 5 year age cohort.</p

Diagnosis, age at diagnosis and gender distribution in SveDem 2008-11.

<p>Data are n (%) for diagnoses, mean age (range) and the female (F)/male (M) distribution percentage (p-value). Statistical differences in gender distribution was calculated by a binomial test, see Methods. AD  =  Alzheimer's disease, VaD  =  Vascular dementia, FTD  =  Frontotemporal dementia, DLB  =  Dementia with Lewy bodies, PDD  =  Parkinson disease dementia, Other  =  Dementia of other causes, Dementia NS  =  Dementia not specified.</p

Family history in FTD and AD.

<p>The data shown in (A) represents the response to questions on the presence of dementia in first-degree and second-degree relatives of patients diagnosed with AD (blue bars) and FTD (red bars). In (B), the responses in FTD cases are divided into age cohorts: 39–64, 65–80, and 81–96 years. For classification purposes, the responses were divided into three categories: Positive family history (Yes), negative family history (No/None known) and Not known (reserved for when questions about family history have not been asked alternatively no response registered).</p
