For those with Alzheimer's dementia, doctors can offer drug and nondrug interventions that may ease the burden of the disease. Doctors often prescribe drugs that may slow the decline in memory and other cognitive skills. You may also be able to participate in clinical trials.

Also, doctors can teach you and your caregivers about strategies to enhance your living environment, establish routines, plan activities and manage changes in skills to minimize the effect of the disease on your everyday life.

Importantly, an early diagnosis also helps you, your family and caregivers plan for the future. You'll have the chance to make informed decisions on a number of issues, such as:

Appropriate community services and resources Options for residential and at-home care Plans for handling financial issues Expectations for future care and medical decisions
