No. Brachial neuralgia is mostly caused by diseases of the brachial plexus nerve itself or compression of the nerve by neighboring tissues, while the cerebral nerve is mainly affected when there is insufficient blood supply to the brain, which may lead to motor nerve and sensory nerve damage, and similar symptoms of brachial neuralgia, which need to be specifically identified in combination with physical examination and imaging tests.
It is important to note that cervical spondylosis may cause brachial neuralgia in addition to cerebral insufficiency of blood supply, so if both symptoms exist at the same time, this disease should be considered with emphasis.
