[8] [9] They referred to the plaques as 'nodules of neuroglial sclerosis'. In 1898, Emil Redlich reported plaques in three patients, two of whom had clinically verified dementia. [10] Redlich used the term 'miliary sclerosis' to describe plaques because he thought they resembled millet seeds, and he was the first to refer to the lesions as ...
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.

In the skin, systemic sclerosis causes hardening and scarring. The skin may appear tight, reddish, or scaly. Blood vessels may also be more visible.
