The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Some blood pressure drugs may help protect against dementia, study shows

A particular class of medication used to treat high blood pressure could protect older adults against memory decline and other impairments in cognitive function, according to a newly published study from Wake Forest University School of Medicine.

Short stressful events may improve working memory

Experiencing chronic stress day after day can produce wear and tear on the body physically and mentally, and can have a detrimental effect on learning and emotion. However, acute stress -- a short stressful incident -- may enhance learning and memory.

Migrant neuron: New imaging studies reveal mechanics of neuron migration

The development of the brain proceeds a little like the European settlement of North America. The earliest pioneers settled on the east coast with subsequent waves of settlers forming communities further and further westward. In cortical regions of the developing brain, generations of young neurons undergo a staged migration as well, with the earliest-born cells staying relatively close to their birthplace and subsequent generations traveling further, ultimately stratifying into six neuronal layers in the mature brain. Now, for the first time, imaging studies have identified the "motors" that propel a unique form of cell migration that creates these layers that

Close caregiver relationship may slow Alzheimer's decline

A study led by Johns Hopkins and Utah State University researchers suggests that a particularly close relationship with caregivers may give people with Alzheimer's disease a marked edge over those without one in retaining mind and brain function over time. The beneficial effect of emotional intimacy that the researchers saw among participants was on par with some drugs used to treat the disease.

Potassium citrate wards off kidney stones in epilepsy patients on ketogenic diet

Children on the high-fat ketogenic diet to control epileptic seizures can prevent the excruciatingly painful kidney stones that the diet can sometimes cause if they take a daily supplement of potassium citrate the day they start the diet, according to research from Johns Hopkins Children's Center.

Nanoparticle-based “chemical nose” sniffs out cancer earlier to improve treatment options

Using a "chemical nose" array of nanoparticles and polymers, researchers at the University of Massachusetts Amherst have developed a fundamentally new, more effective way to differentiate not only between healthy and cancerous cells but also between metastatic and nonmetastatic cancer cells. It is a tool that could revolutionize cancer detection and treatment, according to Vincent M. Rotello, Ph.D., M.Phil., and D. Joseph Jerry, Ph.D., M.S., the investigators who led the study.

Discovery of new molecular pathway for targeting cancer

A UCLA study has identified a way to turn off a key signaling pathway involved in physiological processes that can also stimulate the development of cancer and other diseases. The findings may lead to new treatments and targeted drugs using this approach.

Tamoxifen kills fungus cells and may prevent them from causing disease

An FDA-approved drug used for preventing recurrence of breast cancer shows promise in fighting life-threatening fungal infections common in immune-compromised patients, such as infants born prematurely and patients with cancer. Some scientists suspected that tamoxifen has antifungal properties; now new research from the University of Rochester Medical Center shows that it actually kills fungus cells and stops them from causing disease.

Potential new treatment for Alzheimer’s

Indeed, these carriers tend to develop the disease later than others, but when that happens, it progresses more rapidly and does not respond to medication. Therefore, the bottom line is that carriers of the mutated gene have a greater risk than others for disease progression.

What happens in the womb dictates how well a child does at school

Australian scientists have found that a person's intelligence starts before birth and they say healthy fetal growth helps to improve a child's performance at school.

Preliminary findings in Phase IIA trial point to natural compound NIC5-15's potential in Alzheimer's disease

Researchers at Mount Sinai School of Medicine have found that a compound called NIC5-15, might be a safe and effective treatment to stabilize cognitive performance in patients with mild to moderate Alzheimer's disease.

TGF beta blocker prevents epilepsy following traumatic brain injury

Dr. Alon Friedman, a neurosurgeon, professor and researcher at Ben-Gurion University of the Negev, working with researchers from UC Berkeley, California have identified a TGF Beta Blocker that when given to rats prevents epilepsy after brain damage, according to a new study appearing in the July 15 issue of the Journal of Neuroscience.

Past exercise helps stroke patients recover faster

A person who has exercised regularly prior to the onset of a stroke appears to recover more quickly, say researchers from Mayo Clinic in Florida, who led a national study.

Discovery of novel receptor in the brain, potential target for Alzheimer's

Barrow Neurological Institute researchers have identified a novel receptor in the brain that is extremely sensitive to beta-amyloid peptide (AB) and may play a key role in early stages of Alzheimer's disease.

Estrogen can reduce stroke damage by inactivating a tumor-suppressing protein

Estrogen can halt stroke damage by inactivating a tumor-suppressing protein known to prevent many cancers, Medical College of Georgia researchers say.

Sunitinib shows promise for advanced kidney cancer patients with poor prognosis

Sunitinib prolongs progression-free and overall survival, and is safe and well tolerated in advanced kidney cancer (metastatic renal cell carcinoma) patients with a poor prognosis such as the elderly and those whose cancer has spread to the brain, finds an Article published Online First (www.thelancet.com) and in the August edition of The Lancet Oncology.

Scientists create new way to study brain function

Scientists at Duke University and the University of North Carolina have devised a chemical technique that promises to allow neuroscientists to discover the function of any population of neurons in an animal brain, and provide clues to treating and preventing brain disease.

Turmeric spice and vitamin D may help clear amyloid plaques found in Alzheimer's

UCLA scientists and colleagues from UC Riverside and the Human BioMolecular Research Institute have found that a form of vitamin D, together with a chemical found in turmeric spice called curcumin, may help stimulate the immune system to clear the brain of amyloid beta, which forms the plaques considered the hallmark of Alzheimer's disease.

Research sheds light on social brain development

The capacity to figure out what others are thinking and what they mean is an ability unique to people that's central to our lives. A new study on the neural mechanisms that govern these abilities sheds light on the relation between how people and groups interact, on the one hand, and how the brain develops and functions, on the other.

Scientists discover 27 genes associated with Asperger's syndrome, autistic traits and empathy

Scientists from the University of Cambridge have identified 27 genes that are associated with either Asperger Syndrome (AS) and/or autistic traits and/or empathy. The research will be published tomorrow in the journal Autism Research. This is the first candidate gene study of its kind.
