Exercise improves memory, thinking after stroke, study finds

01.10.2012
Just six months of exercise can improve memory, language, thinking and judgment problems by almost 50 per cent, says a study presented today at the Canadian Stroke Congress.

Toronto researchers found that the proportion of stroke patients with at least mild cognitive impairment dropped from 66 per cent to 37 per cent during a research study on the impact of exercise on the brain.

"People who have cognitive deficits after stroke have a threefold risk of mortality, and they're more likely to be institutionalized," says lead researcher Susan Marzolini of the Toronto Rehabilitation Institute. "If we can improve cognition through exercise, which also has many physical benefits, then this should become a standard of care for people following stroke."

Forty-one patients, of whom 70 per cent had mild to moderate walking problems requiring a cane or walker, followed an adapted aerobic and strength/resistance training program five days a week. Exercises designed to imitate daily life included walking, lifting weights and doing squats.

The research team found "significant improvements" in overall brain function at the conclusion of the program, with the most improvement in attention, concentration, planning and organizing. Muscular strength and walking ability also increased.

The study did not use a control group of people who didn't exercise. However, Ms. Marzolini says, "these results provide compelling evidence that by improving cardiovascular fitness through aerobic exercise and increasing muscle mass with resistance training, people with stroke can improve brain health."

Ms. Marzolini emphasizes the need to give people with stroke-related impairments access to exercise programs. "Modified exercise programs are desperately needed – they can be adapted for people following stroke, and we think they can provide huge health benefits."

"Healthy living is important for reducing your risk for stroke, recovering from stroke and preventing another," says Ian Joiner, director of stroke for the Heart and Stroke Foundation. "All of us should manage our risk factors for stroke and, when needed, have access to information and counseling about strategies to modify our lifestyle choices."

"These healthy lifestyle studies emphasize how important it is to exercise and stay active after stroke," says Dr. Mark Bayley, Co-Chair of the Canadian Stroke Congress and Medical Director of the Neurological Rehabilitation Program at Toronto Rehab. "By doing so, we can increase our chances of a better outcome after stroke."

The Canadian Stroke Congress is co-hosted by the Canadian Stroke Network, the Heart and Stroke Foundation and the Canadian Stroke Consortium.

The Canadian Stroke Network, www.canadianstrokenetwork.ca, is a national research network headquartered at the University of Ottawa. It includes scientists, clinicians and health-policy experts committed to reducing the impact of stroke.

The Heart and Stroke Foundation, www.heartandstroke.ca, a volunteer-based health charity, leads in eliminating heart disease and stroke, reducing their impact through the advancement of research and its application, the promotion of healthy living and advocacy.

Healthy lives free of heart disease and stroke. Together we will make it happen.

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...
