The most common type of dementia after Alzheimer’s disease, vascular dementia occurs when blood flow to the brain is impaired.
The study examined 173 people in Scotland who took a test of their mental ability in 1932 when they were about 11 years old and later developed dementia. This group was compared to one set of control participants of the same age and gender. For another group of controls, the researchers made sure that the cases and controls came from families where the fathers had similar types of occupations.
The people with vascular dementia were 40 percent more likely to have low test scores when they were children than the people who did not develop dementia. This difference was not true for those with Alzheimer’s disease.
“These results point to the importance of reducing the vascular risk factors that can lead to strokes and dementia,” said study author John M. Starr, FRCPEd, of the University of Edinburgh. “Risk factors include high blood pressure, high cholesterol and smoking.”
Starr said the findings support the hypothesis that low childhood IQ acts as a risk factor for dementia through vascular risks rather than the “cognitive reserve” theory. This theory speculates that greater IQ and education create a buffer against the effects of dementia in the brain, allowing people with greater cognitive reserve to stay free of signs of dementia longer, even though the disease has started affecting their brains.
The study was supported by the Alzheimer’s Research Trust and a Royal Society Wolfson Research Merit Award.
The American Academy of Neurology, an association of more than 21,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as epilepsy, dystonia, migraine, Huntington’s disease, and dementia.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
