Keep working at finding the right doctor. Neurologist, Neuropsychologist, Physiologist (physical medicine), or ENT (Ear Nose Throat) for starters. Ones that have a background in brain injury. Keep looking for the right doctors until you get the answers that work and make sense. You can get help, support, and advice online, but clearly from your post she needs direct help from medical professionals experienced in traumatic brain injury.

Strangely, most of the symptoms you mentioned can be symptomatic of a singular vestibular issue. If she also has any complaints of dizziness or balance issues finding a good ENT with a background in brain injury would be a pretty high priority. They have advanced objective testing for many very treatable conditions that could be an underlying cause for a cluster of symptoms that on the surface seem totally unrelated. Strange, but true.
