There is no such thing as neurological blood supply insufficiency. Insufficient blood supply to the nerves in any part of the body can lead to symptoms of corresponding neurological impairment, and common symptoms include dizziness, nausea, loss of muscle tone, arrhythmia and so on. 1. Insufficient blood supply to central nerves: dizziness with rotating vision, nausea, hemiparesis, vomiting, seizure of falling, confusion, weakness of one side of the limbs, speech disorders, weakness of limbs, urinary and defecation disorders and other symptoms can occur. 2. Insufficient blood supply to peripheral nerves: symptoms such as muscle weakness, hypotonia, hypesthesia, weakening or disappearance of some physiological reflexes such as tendon reflexes, etc. may occur. 3. Insufficient nerve blood supply to internal organs: nausea and vomiting, cardiac arrhythmia, dyspnea, gastrointestinal reaction, bladder irritation, infertility and other symptoms. Neurogenic insufficiency of blood supply is not a clear diagnosis of the disease, and it is recommended to consult a doctor for a clear diagnosis and treatment when uncomfortable symptoms occur.
