Aerobic exercise improves brain function in people with schizophrenia, claims study

Aerobic exercise has significantly reduced symptoms in people dealing with schizophrenia, says study. 

Schizophrenia is one of the most severe chronic mental health conditions in which people hear voices, experience paranoia and struggle with concentration.

The study from University of Manchester discovered that, when combined with  medication, 12 weeks of aerobic exercise training can improve patients’ brain functioning than drugs alone.

Researcher Joseph Firth told that, “These findings present the first large-scale evidence supporting the use of physical exercise to treat the neurocognitive deficits associated with schizophrenia.”

Researchers combined data from 10 independent clinical trials with a total of 385 patients with schizophrenia.

Schizophrenia's acute phase is typified by hallucinations and delusions, which are usually treatable with medication. 

However, most patients are still troubled with pervasive 'cognitive deficits'; including poor memory, impaired information processing and loss of concentration. 

The research showed that patients who are treated with aerobic exercise programs, such as treadmills and exercise bikes, in combination with their medication, will improve their overall brain functioning more than those treated with medications alone. 

The areas which were most improved by exercising were patients' ability to understand social situations, their attention spans, and their 'working memory' - or how much information they can hold in mind at one time. 

There was also evidence among the studies that programs which used greater amounts of exercise, and those which were most successful for improving fitness, had the greatest effects on cognitive functioning. 

"Cognitive deficits are one aspect of schizophrenia which is particularly problematic. They hinder recovery and impact negatively upon people's ability to function in work and social situations. Furthermore, current medications for schizophrenia do not treat the cognitive deficits of the disorder," said researcher Firth. 

"We are searching for new ways to treat these aspects of the illness, and now research is increasingly suggesting that physical exercise can provide a solution," he continued. 

 

"These findings present the first large-scale evidence supporting the use of physical exercise to treat the neurocognitive deficits associated with schizophrenia. Using exercise from the earliest stages of the illness could reduce the likelihood of long-term disability, and facilitate full, functional recovery for patients," added Firth.
