Subtle differences in brain anatomy among older individuals with normal cognitive skills may be able to predict both the risk of developing Alzheimer's disease in the following decade and how quickly symptoms of dementia would develop.
A study on the relationship between multiple sclerosis and chronic cerebral venous insufficiency, a narrowing of the extracranial veins that restricts the normal outflow of blood from the brain, found that CCSVI may be a result of MS, not a cause.
Drugs already in development to treat Alzheimer’s disease may eventually be tapped for a different purpose altogether: re-growing the ends of injured nerves to relieve pain and paralysis. According to a new Johns Hopkins study, experimental compounds originally designed to combat a protein that builds up in Alzheimer’s-addled brains appear to make crushed or cut nerve endings grow back significantly faster, a potential boon for those who suffer from neuropathies or traumatic injuries.
After a century of studying the causes of schizophrenia-the most persistent disabling condition among adults-the cause of the disorder remains unknown. Now induced pluripotent stem cells (iPSCs) generated from schizophrenic patients have brought researchers from the Salk Institute for Biological Studies a step closer to a fundamental understanding of the biological underpinnings of the disease.
Tragically, infants experience severe or fatal head trauma as a result of intentional abuse. Shaken baby syndrome, now commonly referred to as non-accidental head trauma, is a serious form of abuse inflicted upon a child. While there have been other studies analyzing the relationship between economic hardship and child abuse, including head trauma, this research focuses specifically on severe head trauma trends in infants.
Of the 4,030 new cases of brain tumors diagnosed in 2010, an estimated 2,880 were in children younger than 15. As many as 15 percent of these pediatric brain tumors occur in the brainstem. Eighty percent of brainstem gliomas (BSG’s) are diffuse intrinsic pontine gliomas (DIPGs), an almost always fatal tumor with no effective treatment. Researchers studied the biology of pediatric brainstem glioma in an effort to advance treatment of this leading cause of brain tumor death in children.
There has been increased awareness in the last year related to head injuries incurred in the NFL as well as in collegiate and high school football.

Low back and leg pain secondary to degeneration of the lumbar spine (spondylolisthesis) is occurring with increasing frequency, concurrent with the rising population of people age 65 and older living in the US. As a result, there has been a marked increase in the rate of spinal fusion operations and corresponding healthcare costs over the past two decades. Researchers at Vanderbilt University Medical Center in Nashville, Tenn. set out to assess the cost-effectiveness of TLIF, a single lumbar fusion surgical technique commonly used to stabilize the vertebrae of the spine and disc between the vertebrae.
Anterior cervical discectomy and fusion (ACDF) has been the mainstay surgical treatment for cervical disc degeneration for many years. A study performed by researchers at Boulder Neurosurgical Associates and the University of Colorado at Boulder suggests that more optimistic patient expectation and mental health are significant factors that lead to improved clinical outcomes and higher patient satisfaction scores following cervical spine surgery.
On December 5, 1960, 4-month-old Theo Dahl, the only son of best-selling author Roald Dahl and actress Patricia Neal, suffered a shattered skull in a horrific traffic accident involving his pram in New York City.

Neurosurgeons have been leaders in the field of traumatic brain injury (TBI) and have served as team physicians at all levels of athletics. In releasing this position statement, the Joint Section on Neurotrauma and Critical Care of the AANS and CNS has acknowledged the seriousness of sports-related head injuries and neurosurgeons’ key role in treatment and prevention.
Glioblastoma, or malignant glioma, is the most common malignant brain tumor, and also the most deadly, because it is very resistant to treatment. In general, current treatments have not yielded significant increases in survival rates, which is why research into novel therapies is so crucial. A novel brain tumor vaccine clinical trial study conducted at UCLA demonstrates a longer survival time in patients with glioblastoma.
Tumors of the pituitary gland, often referred to as “the master gland” can cause striking physical, mental and psychological debilitation in patients.
