Head injuries can alter hundreds of genes and lead to serious brain diseases
Head injuries can adversely affect hundreds of genes in the brain that put people at high risk for diseases including Alzheimer ' s, Parkinson ' s, post-traumatic stress disorder, stroke, ADHD, autism, depression and schizophrenia, life scientists report. The researchers have identified for the first time potential master genes which they believe control hundreds of other genes that are linked to many neurological and psychiatric disorders.

Combating iron in the brain: Researchers find anti-aging micromolecule
The older we get, the more our brain ages. Cognitive abilities decline and the risk of developing neurodegenerative diseases like dementia, Alzheimer ’s and Parkinson’s disease or having a stroke steadily increases. A possible cause is the accumulation of iron molecules within neurons, which seems to be valid for all vertebrates. In a collaborative research project, scientists found that this iron accumulation is linked to a microRNA called m iR-29.

Benzodiazepines, related drugs increase stroke risk among persons with Alzheimer ' s disease
The use of benzodiazepines and benzodiazepine-like drugs was associated with a 20 per cent increased risk of stroke among persons with Alzheimer ’s disease, shows a recent study. Benzodiazepines were associated with a similar risk of stroke as benzodiazepine-like drugs.

Cerebrovascular disease linked to Alzheimer's
While strokes are known to increase risk for dementia, much less is known about diseases of large and small blood vessels in the brain, separate from stroke, and how they relate to dementia. Diseased blood vessels in the brain itself, which commonly is found in elderly people, may contribute more significantly to Alzheimer's disease dementia than was previously believed, according to new study.

Brain structure may be root of apathy
Scientists have found evidence of a biological basis for apathy in healthy people. Research could shed light on the way some people become pathologically apathetic, for example after a stroke or with Alzheimer's disease.

Brain cells' role in navigating environment
A new study sheds light on the brain cells that function in establishing one's location and direction. The findings contribute to our understanding of the neural mechanisms underlying our abilities to successfully navigate our environment, which may be crucial to dealing with brain damage due to trauma or a stroke and the onset of diseases such as Alzheimer's.

Reprogramming 'support cells' into neurons could repair injured adult brains
The cerebral cortex lacks the ability to replace neurons that die as a result of Alzheimer's, stroke, and other devastating diseases. A new study shows that a Sox2 protein, alone or in combination with another protein, Ascl1, can cause nonneuronal cells, called NG2 glia, to turn into neurons in the injured cerebral cortex of adult mice. The findings reveal that NG2 glia represent a promising target for neuronal cell replacement strategies to treat brain injury.

New way to lose weight: Scientists stimulate brown fat to burn more energy from food
The number of overweight persons is greatly increasing worldwide - and as a result is the risk of suffering a heart attack, stroke, diabetes or Alzheimer's disease. For this reason, many people dream of an efficient method for losing weight. Scientists have now come one step closer to this goal. The scientists discovered a new way to stimulate brown fat and thus burn energy from food: The body's own adenosine activates brown fat and "browns" white fat.

Turmeric compound boosts regeneration of brain stem cells
A bioactive compound found in turmeric promotes stem cell proliferation and differentiation in the brain, reveals new research. The findings suggest aromatic turmerone could be a future drug candidate for treating neurological disorders, such as stroke and Alzheimer's disease.

Electric current to brain boosts memory: May help treat memory disorders from stroke, Alzheimer's, brain injury
Stimulating a region in the brain via non-invasive delivery of electrical current using magnetic pulses, called Transcranial Magnetic Stimulation, improves memory. The discovery opens a new field of possibilities for treating memory impairments caused by conditions such as stroke, early-stage Alzheimer's disease, traumatic brain injury, cardiac arrest and the memory problems that occur in healthy aging.

'Switch' in Alzheimer's and stroke patient brains prevents generation and survival of neurons
A new study finds a modification to the transcriptional protein MEF2 that inhibits the growth of new brain cells and survival of existing cells. The findings show promise for therapeutic intervention for a variety of neurodegenerative disorders.

Unprecedented detail of intact neuronal receptor offers blueprint for drug developers
Biologists have succeeded in obtaining an unprecedented view of a type of brain-cell receptor that is implicated in a range of neurological illnesses, including Alzheimer's disease, Parkinson's disease, depression, schizophrenia, autism, and ischemic injuries associated with stroke. The team's atomic-level picture of the intact NMDA receptor should serve as template and guide for the design of therapeutic compounds.

Scientists catch brain damage in the act
Scientists have uncovered how inflammation and lack of oxygen conspire to cause brain damage in conditions such as stroke and Alzheimer's disease, bringing researchers a step closer to finding potential targets to treat neurodegenerative disorders. Chronic inflammation and hypoxia, or oxygen deficiency, are hallmarks of several brain diseases, but little has been known about how they contribute to symptoms such as memory loss.

Chemical reaction keeps stroke-damaged brain from repairing itself
Nitric oxide, a gaseous molecule produced in the brain, can damage neurons. When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer's. Researchers recently discovered that nitric oxide not only damages neurons, it also shuts down the brain's repair mechanisms.
