What’s the Difference Between Alzheimer’s and Dementia?
Dementia is a broad category, while Alzheimer’s disease is a specific type, and the most common cause, of dementia.
What Are the Symptoms of Dementia?
What Causes Dementia?
Dementia results from damage to the brain, and is related to several different neurological conditions that affect cognition, such as Alzheimer’s disease, Parkinson’s disease, stroke, and frontotemporal dementia. Each of these diseases has certain risk factors, including lifestyle and genetics.
The risk of developing dementia increases as people age, but it is not a normal consequence of aging.
Prevalence of Dementia
Approximately half of people over the age of 85 develop Alzheimer’s disease, the most common cause of dementia. Currently, 5.4 million Americans suffer from Alzheimer’s or another dementia.
Diagnosis of Dementia
If you suspect someone has dementia, arrange for a doctor’s appointment for an evaluation. Sometimes, reversible conditions such as normal pressure hydrocephalus or vitamin B12 deficiency can cause confusion or memory loss. An assessment by a doctor can determine if any of those reversible health concerns exist, as well as outline a plan for treatment.
Treatment of Dementia
Treatment of dementia varies. Medications that are approved specifically to treat Alzheimer’s disease are often prescribed to treat other kinds of dementia as well. While some people report seeing very little benefit, others report that these medications seem to temporarily improve cognitive functioning and slow the progression of dementia.
Other ways to respond to changes in cognition and behavior include non-drug approaches like maintaining a daily routine, changing how caregivers respond to the person with dementia, and paying attention to non-verbal communication from your loved one.
There is no sure-fire way to prevent dementia, but research suggests that things such as maintaining an active brain, regular physical exercise, and consuming a healthy diet may reduce the risk of developing Alzheimer’s and other kinds of dementia.
