Do statins prevent vascular dementia?

The most evident protective effect statins have on cognition is the prevention of stroke and possible subsequent vascular dementia. The effects of statins may not only be affecting stroke risk, but may also be preventing microvascular infarcts that lead to dementia without an acute stroke.

Do statins reduce risk of vascular dementia?

When all of the data was analysed together, the researchers found that those people taking statins had a 29 per cent reduced risk of developing dementia.

What prevents vascular dementia?

Keeping your blood pressure in the normal range may help prevent both vascular dementia and Alzheimer's disease. Prevent or control diabetes. Avoiding the onset of type 2 diabetes, with diet and exercise, is another possible way to decrease your risk of dementia.

Do statins alter the risk or progression of dementia?

Dementia risk was evaluated on the basis of statin potency. High potency statin was significantly associated with a decreased risk of dementia risk (RR 0.68, 95% CI 0.54–0.86, p < 0.001), while low potency statin was not associated with a decreased risk of dementia (RR 0.92, 95% CI 0.87–0.97, p = 0.005).

Do statins improve memory?

Interestingly, some studies suggest that statins might improve memory in certain people by lowering the risk of dementia. This benefit could occur because cholesterol is involved in the production of the protein clusters that are the hallmark of neurodegenerative diseases such as Alzheimer's and Parkinson's.

Why are doctors pushing statins?

Key takeaways: Statins are the go-to treatment option for lowering cholesterol levels and risk of cardiovascular complications, like heart attack and stroke. Statins work by slowing down cholesterol production and enabling the liver to remove low-density lipoproteins (LDL), or “bad cholesterol,” from the bloodstream.

Can statins cause Alzheimer's?

Subgroup analysis showed statins use was associated with Alzheimer disease (AD) (RR: 0.81; 95% CI, 0.73–0.89) and non-AD dementia (RR: 0.81; 95% CI, 0.73–0.89) risk decrement.

How many years can you take statins?

Check with your doctor whether there's a particular time of day you should take your statin. You usually have to continue taking statins for life because if you stop taking them, your cholesterol will return to a high level within a few weeks. If you forget to take your dose, do not take an extra one to make up for it.

Do statins improve life expectancy?

The most optimistic estimates say that taking a statin could add a year to the average person's life expectancy. Not smoking could add nearly 10 years and quitting increases life expectancy by reducing the chances of emphysema, many cancers, and heart disease.

What are the neurological side effects of taking statins?

The most common adverse effects include muscle symptoms, fatigue and cognitive problems. A smaller proportion of patients report peripheral neuropathy—burning, numbness or tingling in their extremities—poor sleep, and greater irritability and aggression.

What is the most common cause of vascular dementia?

Vascular dementia is generally caused by conditions that occur most often in older people, such as atherosclerosis (hardening of the arteries), heart disease, and stroke. The number of people older than 65 years is increasing. People are living longer with chronic diseases, such as heart disease and diabetes.

How do you improve vascular dementia?

There is currently no cure for vascular dementia: the brain damage that causes it cannot be reversed. However, there is a lot that can be done to enable someone to live well with the condition. This will involve drug and non-drug treatment, support and activities.

What are the first symptoms most likely to be seen in vascular dementia?

Early signs of vascular dementia can include mild:

• slowness of thought.
• difficulty with planning.
• trouble with understanding.
• problems with concentration.
• changes to your mood or behaviour.
• problems with memory and language (but these are not as common as they are in people with Alzheimer's disease)

What are the pros and cons of taking statin drugs?

Statins are a group of drugs that can reduce high cholesterol, lowering the risk of atherosclerosis and heart problems. Statins typically cause mild side effects, if any, but these drugs can, rarely, cause significant, and even life threatening, adverse effects.

Do statins prevent Alzheimer's?

Overall, the researchers linked high use of statins to a 15 percent lower risk of Alzheimer's in women and a 12 percent lower risk in men compared to those who had low use. Those who took simvastatin (Zocor) had 10 percent to 23 percent lower risk, depending on their gender and race.

Should everyone be on a statin?

The U.S. Preventive Services Task Force recommends low- to moderate-dose statins in adults ages 40 to 75 who have one or more risk factors for heart and blood vessel disease and at least a 1 in 10 chance of having a cardiosvascular disease event in the next 10 years.

Are statins worth the risk?

Research has shown that statins are highly effective in reducing the risk of fatal heart attack and stroke. But some people are reluctant to take these life-saving drugs.

Are statins good for your brain?

Neurological side effects

There is limited evidence to prove a cause-effect relationship, but talk to your doctor if you experience memory loss or confusion while taking statins. There has also been evidence that statins may help with brain function — in people with dementia, for example.

Do all statins cause memory loss?

People who took any kind of cholesterol drug—a statin or some other type—were nearly four times more likely to report memory loss right after starting on the drug, compared with people who didn't take any kind of cholesterol drug.
