Dementia

About Dementia

Dementia itself is not a disease, but rather a collection of symptoms that is caused by some other condition. The causes of dementia can vary, because there are different types of brain changes (i.e., pathology) in different regions of the brain. Many conditions that cause dementia are neurodegenerative, meaning that they cause brain cells to lose function or die off over time. The underlying reasons for the brain changes for most types of neurodegenerative dementias are unknown. Some forms of dementia can be treated and reversed, but others cannot. Therefore, it is important to get an accurate diagnosis so that the best plan can be made.

Types of Dementia

Different forms of dementia are caused by different underlying changes to the brain.

Types of dementia include:

• Alzheimer’s disease: The most common form of dementia which is related to the unhealthy buildup of proteins in the brain called beta-amyloid and tau
• Lewy body dementia:Cognitive impairment associated with the unhealthy accumulation of proteins called Lewy bodies in brain cells
• Vascular dementia: Cognitive impairment caused by a loss of blood flow and oxygen to the brain
• Frontotemporal dementia: Cognitive impairment resulting from unhealthy protein accumulation or damage to the frontal or temporal regions of the brain
• Mixed dementia: A combination of multiple forms of dementia, such as vascular dementia and Alzheimer’s disease

Symptoms of Dementia

The exact symptoms of dementia vary based on the underlying cause and the areas of the brain most affected. In many cases, dementia symptoms become more severe over time.

Symptoms of dementia may include:

• Difficulty planning or solving problems
• Difficulty remembering past events
• Trouble learning new information

Risk Factors for Dementia

Each form of dementia is associated with unique risk factors.

Risk factors for dementia may include:

• Age: Most conditions that cause dementia become more common with advancing age
• Comorbid conditions: Many forms of dementia are associated with another condition that causes damage to the brain. For example, vascular dementia is associated with cardiovascular conditions affecting the blood flow to the brain
• Family history: Some forms of dementia are thought to be influenced by genetics
