Is it possible to treat vascular dementia?
Frontiers of Neurology and Neuroscience
|February 3, 2009
Summary
Preventing vascular dementia through risk factor reduction, particularly hypertension, shows promise. Current curative treatments for vascular dementia remain ineffective, highlighting the need for better clinical trials.
Area of Science:
- Neurology
- Gerontology
- Public Health
Background:
- Vascular dementia is a significant cause of cognitive decline.
- Primary and secondary prevention strategies show disease-modifying effects.
- Current curative treatments have limited efficacy.
Purpose of the Study:
- To evaluate the effectiveness of prevention strategies for vascular dementia.
- To assess the efficacy of current pharmacological treatments.
- To identify needs for future clinical trials in vascular dementia research.
Main Methods:
- Review of randomized controlled trials on vascular dementia prevention and treatment.
- Analysis of cerebrovascular risk factor reduction, including hypertension.
- Evaluation of studies on cholinesterase inhibitors and memantine.
Main Results:
- Preventive strategies effectively reduce cerebrovascular risk factors and may prevent dementia by reducing stroke.
- Disease-modifying treatments demonstrate real effects on vascular dementia progression.
- Curative treatments like cholinesterase inhibitors and memantine show insufficient evidence for widespread use.
Conclusions:
- Prevention of vascular dementia through risk factor management is effective.
- Current curative treatments for vascular dementia are largely ineffective.
- Future research requires well-designed, adequately powered trials addressing disease heterogeneity and specific outcome measures.

01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
01:30Dementia
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual.

01:22Alzheimer's Disease: Treatment
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
01:16Vascular Spasm
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
01:27Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
01:26Atherosclerosis III: Management
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
