There is no one definitive test to diagnose Alzheimer’s disease. Instead, a diagnosis is based on a review of medical and neurological history, a physical exam, a mental status exam, and copious amounts of patient observation. Further, blood work and brain scans may be ordered to rule out other potential causes of memory loss and confusion. In some cases, a lumbar puncture (spinal tap) may be performed to check for the presence of beta-amyloid proteins in the fluid surrounding the brain and spinal cord.

A diagnosis of Alzheimer’s disease is typically made by a neurologist or psychiatrist after taking a careful medical history and performing a physical and mental examination. There are no laboratory tests that can definitively diagnose Alzheimer’s disease, although recent advances have led to the development of brain imaging techniques, such as PET and MRI, which may eventually be useful in distinguishing Alzheimer’s from other causes of dementia.

The doctor will ask about the person’s medical history and any changes in their mood, sleep, or behavior that have been noticed by family and friends. The doctor will also perform a physical examination and order laboratory tests to rule out other causes of dementia, such as thyroid problems or vitamin deficiencies.

If the person is deemed to be cognitively impaired, they will be referred for further testing, which may include neuropsychological testing, brain imaging, and lumbar puncture. A diagnosis of Alzheimer’s disease is made based on the presence of specific changes in the brain on brain imaging, in addition to the person’s clinical symptoms.
