I have been working with aphasia support groups since 2002. Support groups provide a safe place to attempt to speak. They also offer a place to share feelings about the experience of having a stroke, dealing with the health care system, and dealing with experiences after the stroke. Many people with aphasia struggle with anger, sadness, fear, isolation and feelings of helplessness after the stroke. Being able to talk about these feelings over time, and receiving the support of people who understand, gradually helps people to move through these feelings and to find ways to re-engage with life.
Here are two research studies about the effects of stroke on the survivors and co-survivors.
