Education helps against dementia

31.05.2010
Researchers have discovered that education not only delays the early symptoms of dementia, but can also slow down the development of the disease – a finding that could result in faster diagnosis and treatment of dementia, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

Previous studies have shown that education offers some degree of protection against the symptoms of disorders of the brain.

“This mechanism has previously been observed at a late stage of the disease, primarily in cases of Alzheimer’s, which is a type of dementia,” says Sindre Rolstad, researcher at the University of Gothenburg. “We wanted to investigate how education affected the disease in the early stages of dementia, known as mild cognitive impairment.”

People with mild cognitive impairment can be affected by a reduction in their ability to think, such as reduced memory and a short attention span.

“We wanted to find out whether highly educated patients with mild cognitive impairment differed in terms of tolerance of the disease from patients with intermediate and low levels of education,” says Rolstad.

By analysing the patients’ spinal fluid, the researchers were able to examine whether there were signs of dementia in the brain. “Highly educated patients with mild cognitive impairment who went on to develop dementia over the next two years had more signs of disease in their spinal fluid than those with intermediate and low levels of education,” says Rolstad.

Despite having more disease in the brain, the highly educated patients showed the same symptoms of the disease as their less well educated counterparts. This means that patients with higher levels of education tolerate more disease in the brain.

The researchers also studied patients with mild cognitive impairment who did not go on to develop dementia over the next two years. “We found that the highly educated patients who did not develop dementia during the course of the study showed signs of better nerve function than those with lower levels of education,” says Rolstad. “This finding means that the highly educated not only tolerate more disease in the brain but also sustain less nerve damage during the early stages of the disease.”

The results indicate that a higher reserve capacity delays the symptoms of dementia and the progress of the disease. This can help the care sector to be more aware of dementia in highly educated patients, and thus increase the chances of the correct treatment being given.

DEMENTIA
Dementia is a deterioration of the intellect, memory and personality. It results from diseases and damage that affect the brain. Symptoms include forgetfulness, impaired speech and emotional blunting. Dementia is common in Sweden, increasingly so as we get older. It is estimated that around 7% of the Swedish population over the age of 65 and just over 20% of the over-80s have severe dementia.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
