Hi Peggy and welcome to NeuroTalk.
This latest concussion is relatively recent, so it's understandable that he is having the symptoms you describe. Did he have PCS symptoms before this latest fall? These could include headaches, blurred vision, vertigo, sensitivity to light and noise. The neurologist should be made aware when you do get to see him.
In addition to the care you are giving him he should stay away from alcohol:

Best to you both.
