Dementia and Alzheimer’s are degenerative diseases that are slowly gaining awareness. Most of us at least know of one person who suffers from either one of them. However, we often confuse the terms Dementia and Alzheimer’s. It is important that we understand the difference between them.
What is Dementia?
Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. Memory loss is an example.
Dementia is not a specific disease. It’s an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person’s ability to perform everyday activities. Alzheimer’s disease accounts for 60 to 80 percent of cases. Vascular dementia, which occurs after a stroke, is the second most common dementia type. But there are many other conditions that can cause symptoms of dementia, including some that are reversible, such as thyroid problems and vitamin deficiencies.
Dementia is often incorrectly referred to as “senility” or “senile dementia,” which reflects the formerly widespread but incorrect belief that serious mental decline is a normal part of aging.
What is Alzheimer’s?
It is the most common type of dementia. Alzheimer’s causes problems with memory, thinking and behaviour. Symptoms usually develop slowly and get worse over time, becoming severe enough to interfere with day to day life.
Symptoms: Difficulty remembering recent conversations, names or events is often an early clinical symptom; apathy and depression are also often early symptoms. Later symptoms include impaired communication, poor judgment, disorientation, confusion, behaviour changes and difficulty speaking, swallowing and walking.
