Tailored Treatment for Language Recovery After Stroke is Beneficial

Adhering to intensive therapy for loss of language and communication, known as aphasia, is not very beneficial after stroke. Instead, early intervention and spreading the therapy over a longer duration enhances recovery.

The new research from Edith Cowan University (ECU) is published in the International Journal of Stroke.

Study Explains How the Immune System Responds During Stroke
Development of the brain's immune defenses and how they respond to strokes that occur in the first month of life is explained in the new study.

‘Intensive therapy does not offer the desired effect in recovering from the loss of language or communication, following a stroke. Language is a higher-order function that requires thinking and cognition skills, and it should be tailored according to the needs of the patient.’

According to lead author and Associate Professor Erin Godecke from ECU's School of Medical and Health Sciences, the findings can be used to treat aphasia.

"Previously people with aphasia got the majority of their therapy in the first 6-8 weeks after stroke," Professor Godecke said.

"Our research shows that there is no benefit to this. It is likely that the same therapy could be spread over a longer period to enhance recovery, rather than getting a burst at the start and very little over the next months or years," she said.

How to Deal with a Stroke - Signs - Symptoms - Risk Factors - Prevention
Stroke is a brain attack, which occurs when the blood supply to the brain is interrupted. It affects all age groups; according to the WHO, 15 million people are affected by stroke annually.

Aphasia is a neurological disorder that affects language, communication, comprehension, reading, and writing. Around one-third of people who experience stroke suffer from aphasia. It is usually treated with speech therapy.

"We found that when we provided early aphasia therapy, people had a massive increase in their ability to communicate at 12 and 26 weeks after their stroke. They could talk better and had less difficulty finding and using the right words. Importantly though, we also found that if we provided around 10 hours of therapy per week versus nearly 23 hours a week, the results weren't any different. We didn't see any harm, but we didn't see any benefit," Professor Godecke said.

Stroke – Early Warning Signs - Risk Factor - Rehab - Treatment
Stroke can cause permanent disability and it is important to recognize its early warning signs to stop its progress. Early warning signs of stroke include sudden weakness of facial muscles.

Recovering language after stroke is not similar to recovering lost motor skills like walking or moving an arm. This is because language is a higher-order function that requires cognition and thinking.

"We tend to believe that more intensive is always better. However, we're beginning to see data emerge to show us that language recovery might behave a little differently to motor recovery functions such as walking, moving your arm or sitting up," Professor Godecke said.

Drug intervention need not be the only option to help lower your moderately high blood pressure. Lifestyle changes along with herb remedies such as garlic, arjuna, sarpagandha, and olive can serve the purpose.

"We don't need quite as intensive a regimen for language as we do for walking recovery. We might need the same amount of treatment, just spread over a longer period," she added.

The therapy for aphasia needs to tailored according to individual needs and depending on how much each person can tolerate.

"Because language is a higher-order function and it involves more thinking time and cognitive skill, having breaks between sessions may help consolidate learning," Professor Godecke said.
