What causes blurred vision and a headache?

Almost everyone has experienced a headache, which is pain in part or all of the head. If a headache occurs with or causes blurred vision, it may be due to an underlying condition or medical emergency. Causes of a headache and blurred vision will usually have additional symptoms. Some of these conditions can have serious […]

Light and sound therapy may boost brain function

Light and sound therapy may boost brain function

New research in mice reveals that an innovative light and sound stimulation therapy can clear toxic plaque buildup in the brain and reduce some of the symptoms of Alzheimer’s disease and impaired cognitive functioning. A light and sound combination therapy could fight off Alzheimer’s symptoms. The hallmarks of Alzheimer’s disease in the brain include the […]

Can you detect changes in the earth’s magnetic field?

Can you detect changes in the earth’s magnetic field?

Many animals can detect changes in the earth’s magnetic field, and they use this sense to navigate. A recent study finds that humans may also have this ability. Many animals can detect magnetic fields, but can we? We have evolved to detect a range of sensory inputs, including light, sound, and odors. Other members of […]

Manganese and Parkinson’s: Mechanism may explain link

Manganese and Parkinson’s: Mechanism may explain link

New research, published in the journal Science Signaling, details the mechanism through which exposure to manganese can trigger protein misfolding in the brain — which may, in turn, lead to Parkinson’s-like symptoms. The findings may enable an earlier diagnosis of the neurological condition. New research helps explain how and why manganese exposure could lead to […]

Is there a link between stroke and changes in gut bacteria?

Is there a link between stroke and changes in gut bacteria?

New research investigates whether a stroke can affect the diversity of bacterial populations in the gut and whether these changes could influence the brain’s recovery process. A stroke can cause changes in gut bacteria that could last for a long time and impact health outcomes. The Centers for Disease Control and Prevention (CDC) note that […]

Vascular risk factors tied to brain health

Vascular risk factors tied to brain health

New research uncovers a host of vascular risk factors that may affect the health of our brains as we get older. New research finds that some risk factors that affect the health of our blood vessels can also influence the health of our brains into old age. It is no secret that the global population […]

Causes of muscle twitches and how to relieve them

Causes of muscle twitches and how to relieve them

Experiencing a muscle twitch can be uncomfortable and irritating. But what causes a muscle twitch, and could it indicate an underlying health condition? A muscle twitch is an involuntary contraction of the fibers that make up a muscle. Nerves control muscle fibers. When something stimulates or damages a nerve, it causes the muscle fibers to […]

Why do we sleep? Scientists find brain repair mechanism

Why do we sleep? Scientists find brain repair mechanism

Sleep is an important part of the daily life cycle of most animals — including humans. But when an animal sleeps, it leaves itself defenseless in the face of danger. So, what makes sleeping so important that we all take this risk? What effect does sleep have on individual brain cells? Research, both old and […]

How does your brain make sense of ‘the bigger picture?’

How does your brain make sense of ‘the bigger picture?’

Our brains recognize patterns and can “distance” themselves from the details in order to see “the bigger picture.” Researchers are now striving to find out how, exactly, the brain is able to gain perspective. We are yet to learn exactly how our brains establish complex connections. The human brain is a complex piece of machinery, […]

Psychedelics: Risks and benefits of microdosing revealed

New research, published in the journal ACS Chemical Neuroscience, finds both potential benefits and risks of using psychedelic microdosing to treat mental health problems. The study reveals effects on cognitive skills and sociability, as well as metabolic and neuronal consequences. Previous research has shown that magic mushrooms can alleviate hard-to-treat depression. An emerging body of […]
