Effects of Stroke (Brain Attack) When an area of the brain is damaged, which typically occurs with a stroke, an impairment may result. An impairment is the loss of normal function of part of the body. Sometimes, an impairment may result in a disability, or inability to perform an activity in a normal way. Evaluation Procedures for Stroke Tests that may be used to help diagnose a stroke include a CT scan or MRI, and an electroencephalogram. Treatment for Stroke Although there is no cure for stroke, advanced medical and surgical treatments are now available, giving many stroke victims hope for optimal recovery. Rehabilitation for Stroke Stroke rehabilitation works best when the patient, family, and rehabilitation staff works together as a team. Family members must learn about impairments and disabilities caused by the stroke and how to help the patient achieve optimal function again.
