They're widely thought of an early indicator of dementia because they show up deficits in visuo-spatial features and executive performing that show early indications of dementia.

Those who score poorly on these checks can be referred to your neurologist for even more testing, including blood checks to detect amyloid or tau degrees - indicators of Alzheimer's ailment. Other possible biomarkers could include MRI scans or genetic tests that detect gene variants connected to autosomal dominant Alzheimer's.
