Progressive bulbar palsy
Progressive bulbar palsy is a degenerative disease affecting the motor nuclei of the cranial nerves in the medulla oblongata and pons, and is a type of motor neuron disease. It typically manifests after middle age, with a relatively rapid progression. Symptoms include weakness and atrophy of the jaw, facial, tongue, and pharyngeal muscles, leading to dysarthria, dysphagia, and choking on liquids.
View detailsMenstrual migraine
Menstrual migraine is a type of migraine associated with a woman's menstrual cycle, occurring during or around menstruation. It is characterized by recurrent, unilateral or bilateral throbbing headaches, often localized to one side of the head, and may be accompanied by autonomic nervous system dysfunction such as nausea and vomiting. However, patients are typically headache-free during the interictal period.
View detailsCarotid steal syndrome
Carotid steal syndrome refers to a phenomenon where, when one internal carotid artery is occluded, the other internal carotid artery compensates by supplying blood to the affected side through the anterior or posterior communicating artery, leading to insufficient blood supply on the normal side. It is generally divided into two types: carotid-carotid steal and carotid-vertebrobasilar steal. Symptoms may include dizziness, hemiparesis, and paresthesia.
Muscle contracture
Muscle contracture refers to a clinical syndrome characterized by specific gaits and signs due to degeneration and contracture of muscle and fascial fibers in the affected area, leading to restricted joint function. The main symptoms include postural deformity in the contracted area, severe pain around the joint, skin depressions, and restricted abduction and adduction of limb joints.
View detailsMyotonic dystrophy
Myotonic myopathies are a group of muscle disorders characterized by the impaired relaxation of skeletal muscles after voluntary contraction or physical stimulation. This condition is associated with increased muscle excitability upon electrical or mechanical stimulation. Muscle relaxation improves, and symptoms resolve after repeated contractions or electrical stimulation. Myotonia worsens in cold environments. Electromyography reveals continuous high-frequency discharges. This category of diseases includes myotonic dystrophy, congenital myotonia, and paramyotonia congenita.
View detailsBrown-Séquard syndrome
Brown-Séquard syndrome is a clinical complex characterized by ipsilateral upper motor neuron paralysis, loss of deep sensation, impaired fine touch, and vasomotor dysfunction below the lesion level, along with contralateral loss of pain and temperature sensation and preserved bilateral touch sensation, resulting from hemisection or partial damage to a specific segment of the spinal cord. It primarily occurs in the cervical spine.
View detailsSpinal cord infarction
Spinal cord infarction is a persistent loss of spinal cord tissue due to vascular occlusion, primarily involving the vertebral artery radicular branches (cervical spinal cord) or the aorta (thoracic or lumbar spinal cord). It is more common in individuals over 50 years old, and clinical manifestations often include sudden, severe weakness, paralysis, and sensory loss in both lower limbs, back pain radiating to the caudal end, and dissociative sensory loss.
View detailsAnterior cord syndrome
Anterior spinal cord syndrome is a syndrome caused by insufficient blood supply from the anterior spinal artery, leading to ischemia in the anterior spinal artery's supply area, thereby causing damage to spinal nerve function. It often manifests as sudden paralysis (loss of motor function in the lower limbs), low back pain, abnormal sensation in the limbs (inability to feel temperature and pain), and uncontrolled urination and defecation.
View detailsSpinal cord ischemic disease
Spinal ischemic disease is a group of conditions caused by insufficient blood supply to the spinal cord, leading to neurological damage and impaired spinal function. It can manifest as lower limb weakness and intermittent claudication. Spinal ischemia can be classified into transient ischemic attack of the spinal cord, spinal infarction, and spinal embolism.
