What is the difference between Alzheimer’s disease and dementia?
Alzheimer’s disease is a type of dementia. Dementia is a loss of thinking, remembering, and reasoning skills that interfere with a person’s daily life and activities. Alzheimer’s disease is the most common cause of dementia among older people. Other types of dementia include frontotemporal disorders, Lewy body dementia, and vascular dementia.
What are the early signs of Alzheimer’s disease?
Memory problems are typically one of the first signs of Alzheimer’s disease, though different people may have different initial symptoms. A decline in other aspects of thinking, such as finding the right words, vision/spatial issues, and impaired reasoning or judgment, may also signal the very early stages of Alzheimer’s disease.
What are the stages of Alzheimer’s disease?
Alzheimer’s disease progresses in several stages: preclinical, early (also called mild), middle (moderate), and late (severe). During the preclinical stage of Alzheimer’s disease, people seem to be symptom-free, but toxic changes are taking place in the brain. A person in the early stage of Alzheimer’s may exhibit the signs listed above.
What are the causes of Alzheimer’s disease?
Scientists do not yet fully understand what causes Alzheimer’s disease in most people. In early-onset Alzheimer’s, which occurs between a person’s 30s and mid-60s, there may be a genetic component. Late-onset Alzheimer’s, which usually develops in a person’s mid-60s, arises from a complex series of age-related brain changes that occur over decades. The causes probably include a mix of these changes, along with genetic, environmental, and lifestyle factors. These factors affect each person differently.
Is Alzheimer’s disease hereditary?
Just because a family member has Alzheimer’s disease does not mean that you will get it, too. Most cases of Alzheimer’s are late-onset. This form of the disease occurs in a person’s mid-60s and is not linked to a specific change in genes. However, genetic factors appear to increase a person’s risk of developing late-onset Alzheimer’s.
Is there a cure for Alzheimer’s disease?
Currently, there is no cure for Alzheimer’s disease. Some sources claim that products such as coconut oil or dietary supplements can cure or delay Alzheimer’s. However, there is no scientific evidence to support these claims.
The U.S. Food and Drug Administration (FDA) has approved several drugs to treat people with Alzheimer’s disease, and certain medicines and interventions may help control behavioral symptoms.
Is there a way to prevent Alzheimer’s disease?
Currently, there is no definitive evidence about what can prevent Alzheimer’s disease or age-related cognitive decline. What we do know is that a healthy lifestyle — one that includes a healthy diet, physical activity, appropriate weight, and control of high blood pressure — can lower the risk of certain chronic diseases and boost overall health and well-being. Scientists are very interested in the possibility that a healthy lifestyle might delay, slow down, or even prevent Alzheimer’s. They are also studying the role of social activity and intellectual stimulation in Alzheimer’s disease risk.
Where can I find financial help for people with Alzheimer’s disease or their caregivers?
There are several possible sources of financial help, depending on your situation. Looking into programs offered by the government is a great place to start. Several federal and state programs provide help with healthcare-related costs.
