Working on memory after a stroke

How to train working memory after stroke?
Memory loss is something that everyone experiences at times, often increasing with age or a neurological problem such as a stroke. Working memory is what we call short-term memory; it is a key cognitive function that allows individuals to hold information “online” for short periods of time. Working memory is often affected after stroke and traumatic brain injuries resulting in problems with attention and planning. After a stroke, one of the main reasons for not being able to return to work is the cognitive problems.

While there are many therapies addressing problems with motor functions and language, there is currently no satisfactory way to treat the cognitive problems. A new study carried out by Dr. Westerberg has shown that victims of acquired brain injury can improve their attention by using a software-based program (Cogmed) to train working memory. 89% of stroke victims who participated in the training reported that after that they were less easily distracted, less likely to daydream and less likely to lose focus when reading. The study is the first of its kind to demonstrate that working memory training among stroke victims leads to improvements in daily life; yet it was performed on a too small sample to be significant and need be tested some more. Optimistic, Dr. Westerberg reported: “This study is an indication of the broad potential of working memory training. In many ways, we are only beginning to understand the tremendous impact that this kind of focused training can have on individuals suffering from various cognitive limitations.” If the method is once more proved to be truly efficient, it could bring new hope to the stoke survivors who suffer severe working memory deficits that impair their executive functioning and social interaction. Working memory capacity is a fundamental cognitive ability necessary for the rehabilitation of other mental functions. Continue reading →
