The glossopharyngeal nerve is the ninth cranial nerve that originates in the brain and controls taste perception, swallowing, and gland function. It can be damaged by tumors, infections, or injuries, causing difficulty swallowing, pain, and dry mouth. Treatment includes antiepileptic drugs and surgery, which can be monitored to avoid nerve damage. The glossopharyngeal nerve is […]
Optic nerve inflammation, or optic neuritis, can cause eye pain and vision loss, and is often caused by underlying diseases such as multiple sclerosis. Symptoms include pain and vision loss, and diagnosis and treatment by an ophthalmologist is important to prevent permanent vision loss. Optic nerve inflammation — or optic neuritis — occurs when the […]
Fourth nerve palsy is a condition where the fourth cranial nerve responsible for eye movement is damaged or malformed, causing the affected eye to drift and resulting in double vision. It can be congenital or acquired through head trauma, and surgery is usually required to correct eye placement. Head tilt is a common sign, and […]
Radial nerve damage can be caused by pressure, inflammation, or medical conditions. Symptoms include numbness, tingling, and difficulty moving the arm or wrist. Treatment includes medication, physical therapy, and surgery in severe cases. The radial nerve is found in the arm and helps control muscle movement and also allows the wrist to move backwards. This […]
Damage to the laryngeal nerves can cause breathing and speaking difficulties. Causes include trauma, infection, tumors, and surgical complications. Diagnosis is made through imaging and endoscopy. Recovery is possible, but severe damage may require surgery and voice therapy. The upper and lower laryngeal nerves in the throat control the movement and function of the larynx, […]
Nerve shock is a psychiatric illness caused intentionally or negligently by another person. Victims can recover damages, but must prove recognized mental illness and causation. Secondary victims must meet specific requirements. Defendants may pay for psychiatric treatment and damages if found guilty of intentional or negligent infliction. Nerve shock is defined in English law as […]
Facial nerve palsy is paralysis of the face caused by damage to the seventh cranial nerve. It can cause changes in facial expression, impaired taste, hearing and vision, and other symptoms. It can be caused by trauma, tumors, infectious diseases, and congenital conditions. Treatment focuses on compensating for the problems caused by the paralysis. Facial […]
Malignant peripheral nerve sheath tumors are cancerous growths in the soft tissue lining of a nerve, often caused by neurofibromatosis. Symptoms include pain, weakness, and fatigue. Treatment may involve surgery, chemotherapy, and radiation, with a good prognosis if caught early. A malignant peripheral nerve sheath tumor is a cancerous growth that appears in the soft […]
Nerve sheath tumors affect the peripheral nervous system and can be benign or malignant. Schwannomas and neurofibromas are the most common types, with the former being almost always benign. Neurofibrosarcomas are rare and typically diagnosed by biopsy. The cause of these tumors is unknown, but they are often found in individuals with neurofibromatosis. Treatment involves […]
Compressed nerves, also known as pinched nerves, can cause pain or numbness and tingling. They can be caused by injuries, obesity, poor posture, and repetitive movements. Treatment options include rest, physical therapy, medication, and surgery. Regular exercise and good posture can help prevent pinched nerves. A compressed nerve occurs when a nerve receives pressure or […]
Third nerve palsy is a type of paralysis that affects the eye’s functions, caused by damage to the oculomotor nerve. Symptoms vary, and treatment involves a team of doctors and may include surgery. Third nerve palsy, also known as third oculomotor nerve palsy, is a type of paralysis that affects the functions of the eye. […]
Optic nerve hypoplasia is a congenital condition that causes poorly developed vision, often accompanied by hormonal and developmental abnormalities. It is typically diagnosed in children aged three to four years and can lead to abnormal brain function, seizures, and pituitary gland malfunction. There is no cure, but affected individuals may receive regular care from an […]
A cranial nerve exam evaluates the function of the 12 cranial nerves through simple tests such as smelling a strong aroma, assessing hearing with a tuning fork, and checking vision and eye movements. Doctors should ask for consent and wash their hands before the exam. The exam evaluates the trigeminal nerve, controls chewing muscles and […]
Nerve pain in the arm can be caused by a pinched nerve in the neck, often due to a herniated disc or spinal compression. Regular stretching, exercise, and changes to daily routine can help relieve and prevent the pain, but severe symptoms may require medical attention or surgery. Nerve pain in the arm most often […]
Long thoracic nerve palsy causes the scapula to protrude and can result in shoulder pain and loss of motion. It is often caused by direct injury or repetitive motion and can also involve the brachial plexus nerve. Diagnosis involves testing the electrical conductivity of the nerve and treatment options include physical therapy and surgery. Long […]
Fibular nerve damage can occur in various ways, such as through injury or compression, and can lead to loss of feeling in the lower leg and foot motion. Treatment options include surgery, physical therapy, and medication. Fibular nerve damage is damage to the common fibular nerve or one of its branches. This nerve is found […]
Nerve palsy causes weakness or immobility in certain regions of the body. Bell’s palsy is a well-known form that causes paralysis on one side of the face. Treatments include medications, massage, and physical therapy, and there is a chance of spontaneous recovery within three weeks. Nerve palsy is a collective term for a series of […]
A pinched nerve can cause pain in different areas of the body, including the hip, lower back, and legs. The sciatic nerve is the longest nerve and can cause sharp pain, numbness, and tingling if pinched. Femoral nerve pain is often felt in the groin, hips, and thighs. Treatment options vary depending on the cause, […]
Nerve injuries can be caused by various medical situations and conditions, resulting in an array of symptoms. Treatment depends on locating and determining the cause of the injury, and prognosis may not always be good. Complete nerve injuries may be permanent, while partial injuries are more likely to be successful. Neurologists usually treat nerve injuries, […]
