Alzheimer's and Dementia - The Difference


Dementia: The Symptoms

When we talk about dementia, we are talking about symptoms. The term “dementia” describes a set of symptoms that includes things like memory loss, trouble behaving appropriately in social situations, difficulty speaking or understanding language, negative changes in mood and demeanour, and so forth. If a doctor says that a patient has dementia, what the doctor means is that the patient is showing some of these symptoms.


Alzheimer's Disease: The Diagnosis

Dementia has many different causes, and Alzheimer’s disease is one cause of dementia. Using a variety of tests, like blood tests, psychological test, and brain scans, doctors can home in on what may be causing dementia in a particular patient. Sometimes, the answer is that Alzheimer’s is causing the dementia.

Alzheimer’s disease is responsible for around two-thirds of all dementia cases. But there are many other causes of dementia as well.


Other Causes of Dementia

The second most common cause, after Alzheimer’s, is called Lewy body dementia. Parkinson’s disease is another cause. Having a stroke can cause vascular dementia–a dementia that is a result of a lack of blood flow to the brain. Of course because the brain is complex, it’s rare that a person has strictly one cause of dementia with no overlap; for example, Lewy body dementia often overlaps with Alzheimer’s disease and/or Parkinson’s disease.

There are many other, more rare causes of dementia as well, like Huntington’s disease, which is genetically inherited, as well as dementia caused by repetitive brain injury, like you might find in a boxer or football player. Even rarer, dementia can also occur because of Creutzfeldt-Jakob disease (“Mad Cow”.)

Some types of dementias are temporary and reversible. These include dementias caused by poor nutrition, a reaction to a medication, infection, poisoning, tumors, or brain bleeds. In these cases, once the thing causing the dementia is gone, the patient can usually recover normally without symptoms.


BrainHQ and Dementia

Dozens of published, peer-reviewed studies have proven that the brain training exercises in BrainHQ can improve the symptoms of dementia, including memory, auditory processing, brain speed, quality of life, and more. Other studies have found that using the exercises before serious onset of dementia symptoms can help keep them at bay. For example, the IMPACT Study found that participants who used Posit Science exercises increased their auditory processing speed by 131%, experienced an improvement in memory equivalent to approximately 10 years, and reported positive changes in their everyday lives. People didn’t just test better, they noticed changes in their daily lives as well—perhaps the most meaningful result of all. The ACTIVE Study found that the effects of BrainHQ training lasted more than five years without further training.
