Alzheimer’s disease overview.

Alzheimer’s disease is the most common type of dementia. People living with dementia have trouble with memory or making decisions that affect their everyday activities. The cause of Alzheimer's disease has not been found. But scientists believe it’s due to an abnormal buildup of proteins (called amyloid and tau) in and around brain cells. Over time, this buildup blocks brain cells from talking to each other and causes the brain to shrink.

People with Alzheimer’s disease slowly lose their ability to solve problems, make decisions or remember things. It can affect balance, coordination and strength. Some people living with Alzheimer’s disease may experience changes in their emotions or personalities. Over time, they may need to rely on others to take care of themselves.

Symptoms of Alzheimer’s disease can vary. Some common symptoms that can get worse over time may include:

• Anxiety
• Apathy (not caring about other people’s feelings)
• Balance and coordination issues
• Behavioral and personality changes
• Delusions (believing things that aren’t true)
• Depression
• Difficulty naming things or people
• Disorientation and confusion
• Hallucinations (seeing or hearing things that aren’t there)
• Memory loss
• Mood changes
• Trouble making decisions and planning

There is no cure for Alzheimer’s disease right now. Research is ongoing to understand how the disease changes the brain and how to fight it. Medications are available to help slow the disease and manage its symptoms. 

The longer a person has Alzheimer’s disease, the less they can do things for themselves. In the early stages, changes can be made to keep them safely at home.  Alzheimer’s can also be hard on the caregiver(s).  As time goes on, the patient’s needs may increase to the point where staying home isn’t safe. Talk to your doctor about support available for everyone affected by Alzheimer’s disease.
