Stumbled across a paper published in July about how IJV compression needs to be taken more seriously by medical professionals. It also lists all the neurological and nerve-related symptoms caused by (or at least associated with) IJV compression:
intracranial hypertension, headache, tinnitus, dizziness, eye symptoms including pressure and blurring, vertigo, memory disturbances, insomnia, head noises, neck discomfort, ear pain, hearing impairment, cognitive fatigue and brain fog, anxiety or depression, papilledema, thrombosis, and cranial hemorrhage
