The largest risk factor for dementia is age. Heterochronic blood exchange studies have uncovered age-related blood factors that demonstrate 'pro-aging' or 'pro-youthful' effects on the mouse brain. The clinical relevance and combined effects of these factors for humans is unclear.
View Article and Find Full Text PDFLimbic predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) is highly prevalent in late life and a common co-pathology with Alzheimer's disease neuropathologic change (ADNC). LATE-NC is a slowly progressive, amnestic clinical syndrome. Alternatively, when present with ADNC, LATE-NC is associated with a more rapid course.
View Article and Find Full Text PDFFrontotemporal dementia (FTD) is one of the leading causes of young-onset dementia before age 65, typically manifesting as abnormal behavior (in behavioral variant FTD) or language impairment (in primary progressive aphasia). Although FTD affects all populations across the globe, knowledge regarding the pathophysiology and genetics derives primarily from studies conducted in North America and Western Europe. Globally, biomedical research for FTD is hindered by variable access to diagnosis, discussed in this group's earlier article, and by reduced access to expertise, funding, and infrastructure.

- Behavioral variant frontotemporal dementia (bvFTD) is characterized by a range of neuropsychiatric symptoms (NPS) that occur frequently both early and late in the illness, impacting emotional and behavioral aspects.
- A study involving 354 participants identified four main clusters of NPS—affective, disinhibited, compulsive, and psychosis—showing that some symptoms fluctuate while others remain stable over time.
- The findings suggest that NPS could be linked to specific brain network disruptions, providing insight for potential treatments, although the variability in symptoms indicates they may not be reliable indicators of disease progression.
Article Synopsis
- - Cardiovascular health, evaluated through Life's Simple 7 (LS7), is linked to slower cognitive decline and better brain integrity in patients with autosomal dominant frontotemporal lobar degeneration (FTLD).
- - A study involving 247 FTLD genetic variant carriers and 189 non-carrier controls found that those with better cardiovascular health had slower memory and language declines, as well as less accumulation of frontal white matter hyperintensities (WMHs).
- - Maintaining good cardiovascular health could be a key modifiable strategy to improve cognitive outcomes and brain health in individuals at risk for genetic forms of dementia.
