How to check Alzheimer's disease?

In the early days, you can find MMSE scale and MOCA scale for your mother online, or buy a brain early detection kit to measure the concentration of biomarkers for your mother, but the symptoms are getting more and more serious. Please go to the hospital neurology department for diagnosis in time. The tests that hospitals need are: 1. Various cognitive/mental/life ability assessment scales; 2. Routine blood examination; 3. Imaging MRI/CT and PET imaging detection; 4. Cerebrospinal fluid detection. I hope my answer is helpful to you.
