Gains can happen quickly or over time. The most rapid recovery usually occurs during the first three to four months after a stroke, but some stroke survivors continue to recover well into the first and second year post-stroke. Some signs point to physical therapy.
Speech problems following stroke sometimes recover within hours or days, however, some communication problems are more permanent. Some people had help from a Speech and Language Therapist to aid their recovery (see 'Stroke recovery' Communication disorders'). The amount of recovery that can be achieved varies depending on the area of the brain that has been affected and the extent of the damage.
