4 Most Common Types of Dementia

Dementia is a general term which refers to the severe mental inability of an individual which affects his or her ability to perform everyday activities. Memory loss is the ultimate symptom of dementia. Here are four of the most common types of dementia.

Alzheimer’s Disease

Alzheimer’s is the most well-known and prevalent type of dementia with over 60% to 80% of cases. It is a chronic neurodegenerative disease that starts slowly and worsens over time. The mechanisms behind this disorder aren’t well understood, however, the distinguishing feature of the disease is the buildup of amyloid plaques and tau tangles in the brain. A person with Alzheimer’s may experience memory loss, confusion, difficulty talking, anxiousness and paranoia, among others. As of now, there is no treatment for this disease, but there are therapies to better the feeling of the person with Alzheimer’s.

Vascular Dementia

Vascular Dementia, also known as multi-infarct dementia (MID) and vascular cognitive impairment (VCI) is the second most common type of dementia caused by problems in the blood supply to the brain which lead to minor strokes and cognitive decline. A person with Vascular Dementia experiences memory loss, impaired judgment, decreased ability to plan and loss of motivation. Vascular Dementia cannot be cured but there are certain treatments and therapies to prevent further brain damages.

Lewy Body Dementia

This type of dementia worsens over time which is caused by abnormal proteins that appear in the nerve cells and impair the proper functioning of the brain. It is often characterized by sleep problems, memory loss, hallucinations and mood swings. Additional symptoms include visual hallucinations, trouble walking and rigidity. There is no known cure for this type of dementia. Same with Alzheimer’s, its effects can be prevented through various therapies.

Frontotemporal Dementia

This type of dementia is rare. It refers to a group of disorders caused by progressive loss of nerve cells in the brain’s frontal lobes or its temporal lobes. This disorder is often characterized by decreased inhibition, behavioral changes, apathy, loss of motivation, decreased empathy, anxiety, and depression. There is also no cure for this type of dementia, although doctors only provide medicines to treat or prevent the symptoms that make the patient uncomfortable and suffer.

There are also other disorders that often lead to dementia like Parkinson’s disease. Unfortunately, dementia has no cure however, it can be prevented by avoiding things that cause stress and depression.
