Find out how Alzheimer’s affects the brain

'Alzheimer’s disease is a progressive and fatal disease. It is the most common form of dementia and has no cure.

Your brain plays a critical role in almost everything you do: thinking, feeling, remembering, working, playing — even sleeping. Serious memory loss, confusion and other major changes in the way the mind works may be signs of Alzheimer’s.

Take our Brain Tour to learn more about how the brain functions and how Alzheimer’s disease affects it. Featuring images and easy-to-understand language, the interactive Brain Tour guides you through:

 

• Brain basics: 100 billion nerve cells, 100 trillion synapses, dozens of neurotransmitters — these numbers represent your brain’s raw material. Learn about the body’s most powerful organ and how it functions.
   
• Alzheimer’s disease and the brain: Alzheimer’s disease is caused by physical changes in the brain that lead to nerve cell death and tissue loss throughout the brain. Learn how Alzheimer’s disease affects the brain, from the earliest stages to the advanced disease.
