What's the Difference Between Dementia and Alzheimer's?

Dementia and Alzheimer’s disease are often used interchangeably, but they’re not the same. Dementia is an umbrella term for cognitive issues, whereas Alzheimer’s disease is a specific type of dementia. 

If you’re concerned about a loved one exhibiting symptoms of dementia or Alzheimer’s, read on. Our team at Casa de Salud provides senior care services and has experience diagnosing and managing cognitive issues in people of the older generation. 

Understanding Alzheimer’s disease

The history of Alzheimer's starts in 1906, when Dr. Alois Alzheimer saw a 51-year-old female patient who had difficulty performing simple tasks, remembering events, and expressing herself verbally. 

After the patient died, Dr. Alzheimer performed an autopsy on her and found 

abnormal bundles of fibers in her brain, which we now know to be amyloid plaques and phosphorylated tau tangles. 

These changes in the brain are now considered the main hallmarks of Alzheimer’s disease. Interestingly, some fortunate patients who have these brain alterations never develop the cognitive symptoms

The first signs of Alzheimer’s may include the following:

To diagnose Alzheimer's, specialists often use a combination of imaging techniques (to rule out other potential causes of cognitive decline) and neurological testing.

The causes of Alzheimer’s aren’t well understood, but some specialists have noticed that patients who suffer from heart disease and diabetes are more likely to develop Alzheimer’s. Brain insulin resistance, a condition in which the brain doesn’t use insulin properly, is found in some people with Alzheimer’s as well. 

As it stands, there’s no cure for Alzheimer’s. However, there are medications that can improve a patient’s quality of life or slow down the progression of their symptoms.

Understanding dementia 

Dementia is not a disease, but a general term that describes cognitive issues. Alzheimer’s is one type of dementia. Other types of dementia include vascular dementia, Lewy body disease, and frontal lobe dementia. 

All these types of dementia share some common traits, such as problems performing daily tasks, poor decision-making, forgetfulness, and language issues. Some types of dementia, such as Lewy body disease, may involve hallucinations.

Depending on the cause of dementia, the treatment may involve the following:

Vascular dementia, which occurs due to ministrokes inside the brain, can be prevented by maintaining blood pressure within the normal range. In some cases, dementia-like symptoms may also be prevented by avoiding a vitamin B12 deficiency

Vegetarians, vegans, and patients who take metformin for diabetes or proton pump inhibitors and antibiotics to treat H. pylori infections may need to supplement B12 to prevent deficiency.
