Ask the Expert: Alzheimer’s Disease and the Importance of Early Diagnosis

June is Alzheimer’s Disease and Brain Awareness Month—a time to raise awareness not just about Alzheimer’s, but about overall brain health. As we age, changes in memory, thinking, or behavior can be subtle and easy to overlook. But early evaluation by a neurologist can make a meaningful difference. A neurologist specializes in how the brain works and can help figure out what’s causing those changes.

Alzheimer’s disease is the most common cause of dementia, but it’s not the only one. A neurologist can help determine whether symptoms are due to Alzheimer’s, another form of dementia, or even a treatable condition such as medication side effects, vitamin deficiencies, or thyroid problems. The earlier a diagnosis is made, the better the chance of managing symptoms and planning ahead.

In recent years, researchers have made exciting progress in understanding how Alzheimer’s affects the brain. While there’s still no cure, new treatments are being developed that aim to slow down the disease in its earlier stages. A neurologist can talk with you about whether these new options are a good fit, or let you know if there are any clinical trials you might be eligible for.

Neurologists also help patients and families navigate the emotional and practical aspects of living with Alzheimer’s. They can provide guidance on memory care planning, legal and safety concerns, and managing symptoms like anxiety, confusion, or sleep disturbances. Support for caregivers is just as important—neurologists can connect families to resources and strategies that make a difference in day-to-day life.

Alzheimer’s doesn’t just affect memory—it affects families, independence, and quality of life. Seeing a neurologist early and regularly can empower patients and caregivers to make informed choices, access new treatments, and get the support they need every step of the way.
