Dementia Q & A

What are the different types of dementia?

Dementia refers to a group of health conditions that share a similar characteristic: They cause a decline in memory and thinking ability that grows severe enough to affect daily functioning. There are four primary types of progressive dementia:

  • Alzheimer’s disease
  • Vascular dementia
  • Lewy body dementia
  • Frontotemporal disorders

Medical conditions such as hypothyroidism, kidney disease, and vitamin deficiencies can also cause dementia. If your dementia is related to an underlying condition, treating the disease usually improves your dementia.

What symptoms develop due to dementia?

The first sign of Alzheimer’s disease, vascular dementia, and Lewy body dementia is likely to be memory loss. Frontotemporal disorders are more likely to cause unusual behaviors and language problems.

The cognitive symptoms of all the dementias include:

  • Memory loss
  • Confusion
  • Difficulty planning and organizing
  • Struggling to solve problems
  • Difficulty communicating

Dementia also causes psychological and behavioral symptoms such as depression, anger, agitation, and changes in personality. As the disease progresses, all types of dementia may cause hallucinations, inappropriate behavior, and motor symptoms like rigid muscles, tremors, a shuffling walk, or slowed movement.

What should I know about Alzheimer’s disease?

Alzheimer’s disease progressively worsens as plaques and tangles gradually destroy nerves in the brain. Plaques develop when a protein, beta-amyloid, accumulates between nerves in the brain. Tangles are twisted proteins that build up inside nerve cells.

Alzheimer’s disease progresses through stages. At first, patients with Alzheimer’s disease have a hard time remembering new information. Over time, communication becomes increasingly difficult, and their personality and behaviors change.

For example, patients may become angry, aggressive, or suspicious. As the disease enters the late stage, they become less aware of their surroundings and lose the ability to walk, sit, and eat.

How is dementia treated?

Dr. Shayya performs a thorough physical and neurological examination, including tests to evaluate your memory, language, and problem-solving ability. Then he develops an individualized treatment plan that focuses on slowing down disease progression and reducing your symptoms.

Medications called cholinesterase inhibitors are FDA approved for reducing the symptoms of mild to moderate Alzheimer’s disease. These medications may also help patients diagnosed with other types of dementia. A second group of medications, NMDA antagonists, are prescribed to patients with moderate- to late-stage Alzheimer’s disease. These medications improve the ability to perform activities of daily living.
