Do blood tests really help diagnose Alzheimer's disease?

In May 2022, the FDA approved a blood test to help diagnose Alzheimer's disease. The test looks for amyloid-beta protein, a marker of Alzheimer's. The blood test is quite accurate, compared with positron emission tomography (PET) brain scans, which are more expensive and complicated. More blood tests, including some that look for tau protein (another marker of Alzheimer's), also are under development. Other tests used to diagnose Alzheimer's include computed tomography (CT), magnetic resonance imaging (MRI), and a spinal tap.

Brushing off heart failure symptoms

Heart failure symptoms, such as being tired or out of breath, gaining weight, or having swollen ankles, can be overlooked and attributed to other causes. As a result, heart failure is not usually diagnosed until months or years later, when a person is hospitalized for it. By that point, the risk for dying from heart failure has already risen significantly, sometimes higher than the risk of death from cancer. Someone who has potential heart failure symptoms should talk to a doctor, especially if symptoms are new and if the person has diabetes, heart disease, high blood pressure, obesity, or an unhealthy lifestyle.

Spotting memory loss in a loved one

It can be hard to detect a potentially serious type of memory loss in a loved one, especially if small cognitive changes occur over time. It may help to note memory slips that happen consistently or those that seem uncharacteristic for the person. Tracking incidents on a calendar may also help reveal patterns. Potential incidents include consistently forgetting a close family member's name, important conversations, words for everyday objects, bills that are due, medication times or doses, or routes home from familiar places. Other common issues are frequently having trouble at work, making financial mistakes, or taking medications incorrectly.

When walking is the best medicine

Supervised exercise therapy (SET) for peripheral artery disease (PAD) requires pushing through pain while walking to improve blood flow through narrowed blood vessels in the legs. SET can work as effectively as surgical procedures to improve the calf pain and cramping of PAD. SET is a treadmill-based program overseen by clinicians at a health care facility. Home-based SET can work comparably at improving symptoms, but only if PAD patients walk at a faster pace and continue the regimen long-term.

Can music improve our health and quality of life?

Humans' relationship with music is complex and individual, and there are times when music can have a clear and immediate impact on our well-being. Music therapy uses music as a therapeutic tool to address certain health care goals.

Monkeypox: An unfamiliar virus spreading fast — sound familiar?

More than two years after COVID-19 reached the US, an outbreak of monkeypox is spreading fast outside of Africa. This virus is not new, and it's likely to be less dangerous than COVID, but it's still important to be aware of its symptoms, spread, treatment, and prevention.

Ring vaccination might help curtail monkeypox outbreaks

The monkeypox outbreak currently traveling around the globe is the largest ever recorded outside of western and central Africa. Controlling this virus demands preventive measures, and one method that has worked to contain previous disease outbreaks may be effective for monkeypox as well.

Managing weight gain from psychiatric medications

A side effect of many psychiatric medications is weight gain. Antidepressants, antipsychotics, anti-anxiety and sleep medications, and mood stabilizers can all affect metabolism in ways that lead to increased weight, so it's important to know what you can do to lessen this unwanted effect.

Inflammatory bowel disease and family planning: What you need to know

Inflammatory bowel disease is commonly diagnosed at a point in life when many people are planning families. People who have been diagnosed with IBD are likely to have questions and concerns regarding fertility, conception, pregnancy, delivery, and breastfeeding.

Can a vegan diet treat rheumatoid arthritis?

A recent study suggested a vegan diet is an effective treatment for rheumatoid arthritis, and its lead author also said that people should try changing their eating patterns before turning to medication. But there is no evidence that changes in diet can prevent joint damage that occurs in rheumatoid arthritis.
