My 27 year old sister had a stroke 6 months ago. Her recovery was going well until approxiametly 3 months after the stroke she started to experience severe side effects. She has lost muscular control of her eyes, meaning she can see clearly but can't control the movement of her eyes. Her eyes seem to "jump" in her head. She is also experiencing severe dizziness, headaches, and nausea. She has lost all quality of life. Any help?
