Unfortunately, getting an Alzheimer’s disease diagnosis is not simple. Your doctor can’t check for the disease by doing a quick blood test. That’s because signs of Alzheimer’s disease don't appear in your blood. Instead, Alzheimer’s disease is the result of a problem inside your brain.
The only way to be 100% certain a person suffers from Alzheimer’s disease is to examine samples of brain tissue. This can only be done during an autopsy, after a person has died.
Alzheimer's disease or Alzheimer's-type dementia is a progressive degeneration of brain tissue that primarily strikes people over age 65. It is the most common cause of dementia and is marked by a devastating mental decline. Intellectual functions such as memory, comprehension, and speech deteriorate.
Memory impairment is an essential feature of Alzheimer’s disease and is often the first sign. Recent memory is lost first. As time goes on, attention tends to stray, simple calculations...

Because it is difficult to diagnosis this condition, it’s a good idea to work with a doctor experienced in Alzheimer’s disease diagnosis. Doctors to consider include:
Primary care doctors with experience in treating people with Alzheimer’s disease
When looking for Alzheimer’s disease, doctors eliminate all other possible explanations of the symptoms. Dementia, for example, has many other causes besides Alzheimer’s disease. Some of these causes include vitamin deficiency and thyroid problems. With treatment, both these problems can be resolved.
Your doctor makes a “probable” Alzheimer’s disease diagnosis only when all other causes have been ruled out. Following are the steps your doctor will take while deciding on an Alzheimer’s disease diagnosis.
Step 1: A Complete Health History
Knowing about your health history helps your doctor discover whether there are other possible causes for your symptoms. For example, apathy is common in early- stage Alzheimer’s disease. Apathy may also be caused by depression. Your doctor will ask you about:
