Hello and hope you are doing well.
It is difficult to predict the outcome after a stroke. Strokes can be either due to a clot or a bleed. The human brain has great redundancy. In some cases memory is damaged. In other strokes only partial paralysis may be involved, which may disappear. As to whether or not the patient can be "just like they were", the answer is "probably not", however with a caveat. Some stroke patients do appear to have 100 percent recovery. And many regain a great deal of their abilities. Usually the finer functions take longer to recover.
Hope this helped and do keep us posted.
The residual effects of a stroke depend upon the immediacy and effectiveness of treatment and rehabilitation, according to the Brain Foundation. Full recovery may be limited by the type and severity of impairment, the location of the stroke and the amount of damage to the surrounding brain tissue. Although a return to normal activities is always encouraged, limitations may prevent complete recovery, and care must be taken to pace rehabilitation protocols with the abilities of the patient.
