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.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
