   How do brain tests help diagnose Alzheimer's disease?

   • These tests can help establish a diagnosis and serve as a starting point to track symptoms in the future. Images of the brain are typically used to pinpoint visible changes related to conditions other than Alzheimer's disease that may cause similar symptoms, such as strokes, trauma or tumors.

You can find tests online that say they can test your memory and tell if you may have Alzheimer's. One example is a test for signs of dementia or Alzheimer's called the Self-Administered Gerocognitive Exam (SAGE).

   How is Alzheimer's diagnosed?

   • Collect cerebrospinal fluid (CSF) via a spinal tap and measure the levels of proteins associated with Alzheimer’s and related dementias. Perform brain scans, such as computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET), to support an Alzheimer’s diagnosis or rule out other possible causes for symptoms.

   There is no single test that can determine if a person is living with Alzheimer’s or another dementia. Physicians use diagnostic tools combined with medical history and other information, including neurological exams, cognitive and functional assessments, brain imaging (MRI, CT, PET) and cerebrospinal fluid or blood tests to make an accurate diagnosis.

   Feb 13, 2024 · Magnetic resonance imaging (MRI).MRI uses radio waves and a strong magnetic field to produce detailed images of the brain. While they may show shrinkage of some brain regions associated with Alzheimer's disease, MRI scans also rule out other conditions. An MRI is generally preferred to a CT scan to evaluate dementia.
