An ingredient in many curry dishes could hold the key to brain repair, scientists have said.
According the the research from Germany, an ingredient in the yellow curry spice turmeric may hold the key to repairing the brains of people with neurodegenerative diseases such as Alzheimer's.
In laboratory tests, aromatic turmerone promoted the proliferation of brain stem cells and their development into neurons, effectively 'regenerating' brain tissue.
The bio-active compound could help scientists develop treatments for conditions in which brain cells are lost, including Alzheimer's and stroke, it is claimed.
Lead researcher Dr Adele Rueger, from the Institute of Neuroscience and Medicine in Julich, Germany, said:
While several substances have been described to promote stem cell proliferation in the brain, fewer drugs additionally promote the differentiation of stem cells into neurons, which constitutes a major goal in regenerative medicine. Our findings on aromatic turmerone take us one step closer to achieving this goal.
A new report has made the case for raising awareness about the way lifestyle choices can affect your risk of dementia later in life.
It points out "there is no evidence strong enough at this time to claim that lifestyle changes will prevent dementia on an individual basis". However, evidence suggests the following could result in a lower risk:
- Stopping smoking
- Improved detection and treatment of diabetes and hypertension
- Increased physical activity and reduction in levels of obesity
- Education in early life
Dr Eric Karran, director of research at charity Alzheimer's Research UK, has welcomed today's report, saying:
Although there is currently no certain way to prevent dementia, this report underlines strong evidence suggesting we can lower our risk by adopting a healthy lifestyle.
A large body of research has linked high blood pressure, smoking and diabetes to an increased risk of dementia, and this analysis serves as another reminder that good heart health is an important route to good brain health.
Studies have also suggested that education in early life may help build a level of 'cognitive reserve', helping the brain to withstand the damage from diseases like Alzheimer's for longer in later life.
