Ans: Stress does not produce vertigo on its own but it can worsen the symptoms of vertigo or the condition. Stress in general increases the risk of stroke in a person which can again cause vertigo. Stress and anxiety are also responsible for dysfunction in the vestibular system. If any part of the vestibular system is hampered, it can cause dizziness or vertigo. If stress hormones (or cortisol) increase in your body it can negatively impact how neural information is transmitted from the brain to the body. It is also said that these hormones can cause disruption in neurotransmission in the brain and ion channels. When you are stressed your body produces histamines and neurosteroids which may be responsible for indirectly impairing neurotransmission from the vestibule system to the brain.
