understanding Dementia: Causes, Treatments, and Prevention Strategies
As we age, many of us experience moments of forgetfulness. But when does this become a sign of something more serious, like dementia? Dementia is not just about memory loss; it encompasses a range of cognitive impairments, including language difficulties, spatial disorientation, and even personality changes. These symptoms arise from brain lesions that disrupt normal brain function.
The Three Major Types and Causes of Dementia

According to Dr. Zhou Youfang, a neurologist at Yangming Hospital of Taipei Municipal United Hospital, dementia can be categorized into three main types based on its causes:
- Degenerative Dementia: This type is caused by the long-term buildup of abnormal proteins in the brain, leading to conditions like Alzheimer’s disease and Parkinson’s disease dementia.
- Vascular Dementia: Resulting from cerebrovascular damage, such as strokes, this type gradually impairs cognitive function.
- Reversible Dementia: Triggered by infections, endocrine disorders, or nutritional deficiencies, this form can perhaps be reversed with timely treatment. Examples include neurosyphilis, AIDS, hypothyroidism, and vitamin B12 or folic acid deficiencies.
| Type of Dementia | Causes | Examples |
|—————————-|—————————————————————————|———————————————–|
| Degenerative | Abnormal protein buildup | Alzheimer’s, Parkinson’s dementia |
| Vascular | Cerebrovascular damage (e.g., stroke) | Stroke-related cognitive decline |
| Reversible | Infections, endocrine issues, or nutritional deficiencies | Neurosyphilis, hypothyroidism, vitamin B12 deficiency |
Breakthroughs in Dementia treatment
recent studies, including the Reversal of Cognitive Decline program by a University of California professor, highlight promising approaches to slowing dementia progression. By addressing lifestyle factors and tailoring treatments to individual needs, mild dementia patients (with MOCA scores ≥19) have shown meaningful advancement.
Dr. Zhou also emphasizes the role of medications like acetylcholinesterase inhibitors and NMDA receptor antagonists, such as memantine, in managing Alzheimer’s symptoms. These drugs protect brain cells from damage caused by excessive nerve activity. Though,as brain neurons continue to deteriorate,their effectiveness diminishes over time.
A groundbreaking progress in Alzheimer’s treatment involves targeting amyloid plaques in the brain. While this approach shows potential in delaying dementia, it comes with risks like brain edema and hemorrhage, as well as high costs.
Prevention: the Best Defence Against Dementia
the key to combating dementia lies in prevention. Adopting a Mediterranean diet, engaging in regular exercise, and maintaining mental activity can considerably reduce the risk. Dr. Zhou stresses the importance of early detection: “Abnormal memory, poor judgment, or emotional changes should prompt a visit to a neurologist. Early intervention can effectively delay disease progression.”
Take Action Today
Dementia is a complex condition, but understanding its causes and treatments empowers us to take proactive steps. Whether it’s adjusting your diet, staying physically active, or seeking medical advice at the first sign of symptoms, every effort counts.

By staying informed and proactive, we can better navigate the challenges of dementia and improve quality of life for ourselves and our loved ones.
Examining the Causes, Symptoms, and Prevention of Dementia with Dr. Zhou Youfang
Editor: dr. Zhou,could you start by explaining what dementia is and its main symptoms?
Dr. Zhou Youfang: Dementia refers to a group of cognitive disorders that impair memory, thinking, and social abilities enough to interfere with daily life. Common symptoms include memory loss, difficulty speaking or understanding language, spatial disorientation, and even changes in personality. these occur due to brain lesions or other disruptions in normal brain function.
Editor: What are the main types of dementia and their causes?
Dr. Zhou: Dementia can be classified into three major categories based on their causes:
1. Degenerative Dementia: Caused by long-term accumulation of abnormal proteins in the brain, leading to conditions like Alzheimer’s and Parkinson’s disease dementia.
2. Vascular Dementia: Results from cerebrovascular damage, such as from strokes, which gradually impair cognitive function.
3. Reversible dementia: Triggered by infections, endocrine disorders, or nutritional deficiencies, this type can sometimes be reversed with timely treatment.Examples include neurosyphilis, AIDS, hypothyroidism, and vitamin B12 deficiencies.
Editor: Are there any recent breakthroughs in dementia treatment?
Dr. zhou: Yes, programs like the Reversal of Cognitive Decline by a University of California professor show promise in slowing dementia progression. Addressing lifestyle factors and tailoring treatments to individual needs have helped mild dementia patients considerably improve. Medications such as acetylcholinesterase inhibitors and memantine are also effective in managing Alzheimer’s symptoms by protecting brain cells from excessive nerve activity damage. More recently, targeting amyloid plaques shows potential, though it comes with risks like brain edema and hemorrhage.
Editor: How can people lower their risk of developing dementia?
Dr. Zhou: Prevention is key. A Mediterranean diet, regular exercise, and keeping mentally active can all help reduce the risk. Early detection is also crucial. Any signs of abnormal memory, poor judgment, or emotional changes should prompt a visit to a neurologist.Early intervention can effectively delay disease progression and improve quality of life.
Editor: What final advice would you give to our readers?
Dr. Zhou: Stay informed and proactive.Understand the causes and symptoms of dementia. Adopt healthy lifestyle habits and seek medical advice early if you notice any concerning signs. By taking these steps, we can better manage dementia risk and improve outcomes for ourselves and our loved ones.
Conclusion
Dementia, a complex condition with various causes and symptoms, can be managed and potentially delayed through early intervention and preventive measures.By adopting a healthy lifestyle, staying mentally active, and seeking timely medical advice, we can significantly reduce the risk and impact of dementia.
