Flow chart depicting the role of apomorphine in Alzheimer's disease. A more recent variation of the amyloid hypothesis identifies the cytotoxic species as an intermediate misfolded form of amyloid beta, neither a soluble monomer nor a mature aggregated polymer but an oligomeric species, possibly toroidal or star-shaped with a central channel ...
Vascular dementia was found to have either comparable or worse survival rates when compared to Alzheimer's disease; [22] another 2014 study found that the prognosis for people with vascular dementia was worse for male and older people. [23] Vascular dementia may be a direct cause of death due to the possibility of a fatal interruption in the ...
The same is true in a unit cell; no matter how the atoms are arranged, there will be interstitial sites present between the atoms. These sites or holes can be filled with other atoms (interstitial defect). The picture with packed circles is only a 2D representation. In a crystal lattice, the atoms (spheres) would be packed in a 3D arrangement ...
Frontotemporal dementia (FTD) is an early onset disorder that mostly occurs between the ages of 45 and 65, [13] but can begin earlier, and in 20–25% of cases onset is later. [11] [14] Men and women appear to be equally affected. [15] It is the most common early presenting dementia. [16]

Age and education have a significant influence on the diagnosis of dementia. For example, Individuals with lower education are more likely to be diagnosed with dementia than their educated counterparts. [113] While many tests have been studied, [114] [115] [116] presently the mini mental state examination (MMSE) is the best studied and most ...
The team compared 2019 Medicare dementia diagnoses in people 66 and older in each region with the number of expected new cases in that geographical area based on potentially modifiable risk ...
Binswanger's disease is a type of subcortical vascular dementia caused by white matter atrophy to the brain. However, white matter atrophy alone is not sufficient for this disease; evidence of subcortical dementia is also necessary.
