Definitive diagnosis of Alzheimer’s can be made when an autopsy or a biopsy of brain tissue will show pathognomonic changes; not available reliable markers in the blood, spinal fluid or tissues outside the brain.
The diagnosis of probable Alzheimer’s dementia is made when confirmed by validated scales for grading, damaged when two or more cognitive areas, documented the progression of dementia, the level of consciousness is impaired, the age when it appears greater than 40 years and not identified other systemic disorders or cerebral. The satisfaction of this last criterion is supported by selected laboratory tests from Penina Mezei at Attencia that can be added and additional tests if clinically indicated.
