This part of the body is called the pelvic area. Structures inside and near the pelvis include the bladder, prostate and other male reproductive organs, female reproductive organs, lymph nodes, and pelvic bones. An MRI does not use radiation. Single MRI images are called slices.
The type of dementia caused by small strokes, vascular dementia, is also sometimes referred to as âsmall vessel diseaseâ or multi-infarct dementia because it is caused by small strokes (infarcts) caused by blood clots in the small blood vessels of the brain.
Less common causes of dementia that cannot be reversed include: 1  Huntington's disease. 2  Leukoencephalopathies, which are diseases that affect the deeper, white-matter brain tissue. 3  Creutzfeldt-Jakob disease, a rare and fatal condition that destroys brain tissue.
