Dementia is a broad term referred to severe changes in the cognitive system which trigger memory loss. Those problems make it harder for affected people to do some basic tasks in work or school. In many cases, the condition can even lead to several changes in their personality and behavior. Three brain areas are often affected, including decision making, memory, and language. Most of the reported cases cannot be reversed. It is important to keep informed about the following causes of dementia to take preventive measures.
Alzheimer’s Disease
One of the most common causes of dementia is Alzheimer’s disease. It is estimated that this condition accounts for up to 80 percent of the reported cases. People with Alzheimer’s disease tend to experience the death of many brain cells over time. When the symptoms progress, they would cause some permanent changes in the brain and lead to many mental issues, such as mood changes, confusion, as well as difficulties walking or speaking. Older people, ranging from 40 to 50 years old, are at a much higher risk of developing Alzheimer’s than younger people. [1]
