Dementia Q & A

What is dementia?

Dementia refers to memory loss that occurs together with a decline in your ability to think, communicate, and reason. Your memory loss is significant enough to disrupt your life, and the changes get progressively worse.

What are the different types of dementia?

There are four primary types of progressive dementia:

Alzheimer's disease

Alzheimer's develops as beta-amyloid proteins accumulate outside neurons in your brain, while tau proteins build up inside the nerve cells. As these proteins spread throughout your brain, they destroy more neurons, and that part of the brain shrinks.

Lewy body dementia

Lewy body dementia occurs when proteins called Lewy bodies accumulate in your brain. Lewy bodies also cause Parkinson's disease dementia.

Frontotemporal dementia

This type of dementia develops when several different proteins accumulate and cause nerve degeneration.

Vascular dementia

Vascular dementia occurs when decreased blood flow damages your brain. These changes occur gradually due to conditions such as atherosclerosis, high blood pressure, and autoimmune diseases.

What symptoms occur due to dementia?

Each person with dementia develops symptoms at a different pace. However, they can expect to experience problems such as:

  • Memory loss and confusion
  • Difficulty communicating (speaking and writing)
  • Problems concentrating and organizing
  • Trouble with directions and getting lost in familiar places
  • Changes in personality, mood, and behaviors
  • Inability to complete daily tasks
  • Balance and movement problems
  • Changes in gait (walking slower)

Memory loss is the earliest symptom of Alzheimer's. By comparison, frontotemporal dementia's first symptoms include dramatic behavioral and personality changes. 

However, as all the dementias progress, they eventually cause the same symptoms. For example, people develop behavioral and personality changes in the late stages of Alzheimer's.

How is dementia treated?

Dr. Ravitz at Modern Migraine MD does a comprehensive assessment for dementia and looks for other causes of memory loss that are treatable. 

Dementia is also a symptom of health conditions such as immune disorders, endocrine abnormalities (thyroid problems), nutritional deficiencies, and brain tumors. Treating the underlying condition usually reverses the dementia.

If Dr. Ravitz diagnoses you with Alzheimer's disease or Lewy body dementia, she can prescribe medications that may improve your symptoms.

Some medications for Alzheimer's slow down the progressive nerve destruction by reducing beta-amyloid proteins; other drugs may slow down memory loss and improve thinking and language abilities in both types of dementia.
