In BCC metals, interstitial sites of an unstrained lattice are equally favorable. The interstitial solutes create elastic dipoles. [ 14 ] However, once a strain is applied on the lattice, such as that formed by a dislocation, 1/3 of the sites become more favorable than the other 2/3.
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 ...
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 ...
In community samples, cutoff scores for likely dementia have ranged from 3.3 and above to 3.6 and above, while in patient samples the cutoff scores have ranged from 3.4 and above to 4.0 and above. [3] To improve the detection of dementia, the IQCODE can be used in combination with the Mini-Mental State Examination.
The hallmark symptom of LATE is a progressive memory loss that predominantly affects short-term and episodic memory. [1] This impairment is often severe enough to interfere with daily functioning and usually remains the chief neurologic deficit, unlike other types of dementia in which non-memory cognitive domains and behavioral changes might be noted earlier or more prominently.

[10] [20] Visual and tactile cues, adaptive equipment and digital aids to manipulate text may all be beneficial. [26] People with PCA and their caregivers are likely to have different needs than the more typical cases of Alzheimer's disease, and may benefit from specialized support groups, or other groups for young people with dementia.
Dementia with Lewy bodies (DLB) is a type of dementia, a group of diseases involving progressive neurodegeneration of the central nervous system. [11] It is one of the two Lewy body dementias, along with Parkinson's disease dementia. [12] Dementia with Lewy bodies can be classified in other ways.
