If the symptoms of<unk>  last longer than two or three months after a stroke, a complete recovery is unlikely. However, it is important to note that some people continue to improve over a period of years and even decades. Improvement is a slow process that usually involves both helping the individual and family understand the nature of<unk>  and learning compensatory strategies for communicating. After a traumatic brain injury (TBI) or cerebrovascular accident (CVA), the brain undergoes several healing and re-organization processes, which may result in improved language function. This is referred to as spontaneous recovery. Spontaneous recovery is the natural recovery the brain makes without treatment, and the brain begins to reorganize and change in order to recover. There are several factors that contribute to a person's chance of recovery caused by stroke, including stroke size and location. Age, sex, and education have not been found to be very predictive. There is also research pointing to damage in the left hemisphere healing more effectively than the right. Specific to<unk> , spontaneous recovery varies among affected people and may not look the same in everyone, making it difficult to predict recovery. Though some cases of Wernicke's<unk>  have shown greater improvements than more mild forms of<unk> , people with Wernicke's<unk>  may not reach as high a level of speech abilities as those with mild forms of<unk> .
