Clinical Information

• Bell Palsy-. a syndrome characterized by the acute onset of unilateral facial paralysis which progresses over a 2-5 day period. weakness of the orbicularis oculi muscle and resulting incomplete eye closure may be associated with corneal injury. pain behind the ear often precedes the onset of paralysis. this condition may be associated with herpesvirus 1, human infection of the facial nerve. (adams et al., principles of neurology, 6th ed, p1376)
• Brachial Plexus Neuropathies-. diseases of the cervical (and first thoracic) roots, nerve trunks, cords, and peripheral nerve components of the brachial plexus. clinical manifestations include regional pain, paresthesia; muscle weakness, and decreased sensation (hypesthesia) in the upper extremity. these disorders may be associated with trauma (including birth injuries); thoracic outlet syndrome; neoplasms; neuritis; radiotherapy; and other conditions. (from adams et al., principles of neurology, 6th ed, pp1351-2)
• Brown-Sequard Syndrome-. a syndrome associated with injury to the lateral half of the spinal cord. the condition is characterized by the following clinical features (which are found below the level of the lesion): contralateral hemisensory anesthesia to pain and temperature, ipsilateral loss of propioception, and ipsilateral motor paralysis. tactile sensation is generally spared. (from adams et al., principles of neurology, 6th ed, p162).
• Bulbar Palsy, Progressive-. a motor neuron disease marked by progressive weakness of the muscles innervated by cranial nerves of the lower brain stem. clinical manifestations include dysarthria, dysphagia, facial weakness, tongue weakness, and fasciculations of the tongue and facial muscles. the adult form of the disease is marked initially by bulbar weakness which progresses to involve motor neurons throughout the neuroaxis. eventually this condition may become indistinguishable from amyotrophic lateral sclerosis. fazio-londe syndrome is an inherited form of this illness which occurs in children and young adults. (adams et al., principles of neurology, 6th ed, p1091; brain 1992 dec;115(pt 6):1889-1900)
• Delayed Emergence from Anesthesia-. abnormally slow pace of regaining consciousness after general anesthesia (anesthesia, general) usually given during surgical procedures. this condition is characterized by persistent somnolence.
• Facial Paralysis-. severe or complete loss of facial muscle motor function. this condition may result from central or peripheral lesions. damage to cns motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. facial nerve diseases generally results in generalized hemifacial weakness. neuromuscular junction diseases and muscular diseases may also cause facial paralysis or paresis.
• Herpesvirus 2, Gallid-. the type species of the genus mardivirus in the family herpesviridae. it is the etiologic agent of marek disease, infecting domestic fowl and wild birds.
• Hypokalemic Periodic Paralysis-. an autosomal dominant familial disorder characterized by recurrent episodes of skeletal muscle weakness associated with falls in serum potassium levels. the condition usually presents in the first or second decade of life with attacks of trunk and leg paresis during sleep or shortly after awakening. symptoms may persist for hours to days and generally are precipitated by exercise or a meal high in carbohydrates. (adams et al., principles of neurology, 6th ed, p1483)
• Marek Disease-. a transmissible viral disease of birds caused by avian herpesvirus 2 (herpesvirus 2, gallid) and other mardivirus. there is lymphoid cell infiltration or lymphomatous tumor formation in the peripheral nerves and gonads, but may also involve visceral organs, skin, muscle, and the eye.
• Myotonic Disorders-. diseases characterized by myotonia, which may be inherited or acquired. myotonia may be restricted to certain muscles (e.g., intrinsic hand muscles) or occur as a generalized condition.
• Neurosyphilis-. infections of the central nervous system caused by treponema pallidum which present with a variety of clinical syndromes. the initial phase of infection usually causes a mild or asymptomatic meningeal reaction. the meningovascular form may present acutely as brain infarction. the infection may also remain subclinical for several years. late syndromes include general paresis; tabes dorsalis; meningeal syphilis; syphilitic optic atrophy; and spinal syphilis. general paresis is characterized by progressive dementia; dysarthria; tremor; myoclonus; seizures; and argyll-robertson pupils. (adams et al., principles of neurology, 6th ed, pp722-8)
• Oculomotor Nerve Diseases-. diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. with a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. commonly associated conditions include neoplasms, craniocerebral trauma, ischemia (especially in association with diabetes mellitus), and aneurysmal compression. (from adams et al., principles of neurology, 6th ed, p270)
• Ophthalmoplegia-. paralysis of one or more of the ocular muscles due to disorders of the eye muscles, neuromuscular junction, supporting soft tissue, tendons, or innervation to the muscles.
• Paralyses, Familial Periodic-. a heterogenous group of inherited disorders characterized by recurring attacks of rapidly progressive flaccid paralysis or myotonia. these conditions have in common a mutation of the gene encoding the alpha subunit of the sodium channel in skeletal muscle. they are frequently associated with fluctuations in serum potassium levels. periodic paralysis may also occur as a non-familial process secondary to thyrotoxicosis and other conditions. (from adams et al., principles of neurology, 6th ed, p1481)
• Paralysis-. a general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. this term may also occasionally refer to a loss of sensory function. (from adams et al., principles of neurology, 6th ed, p45)
• Paralysis, Hyperkalemic Periodic-. an autosomal dominant familial disorder which presents in infancy or childhood and is characterized by episodes of weakness associated with hyperkalemia. during attacks, muscles of the lower extremities are initially affected, followed by the lower trunk and arms. episodes last from 15-60 minutes and typically occur after a period of rest following exercise. a defect in skeletal muscle sodium channels has been identified as the cause of this condition. normokalemic periodic paralysis is a closely related disorder marked by a lack of alterations in potassium levels during attacks of weakness. (adams et al., principles of neurology, 6th ed, p1481)
• Paralysis, Obstetric-. paralysis of an infant resulting from injury received at birth. (from dorland, 27th ed)
• Paraplegia-. severe or complete loss of motor function in the lower extremities and lower portions of the trunk. this condition is most often associated with spinal cord diseases, although brain diseases; peripheral nervous system diseases; neuromuscular diseases; and muscular diseases may also cause bilateral leg weakness.
• Parkinson Disease-. a progressive, degenerative neurologic disease characterized by a tremor that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. lewy bodies are present in the substantia nigra and locus coeruleus but may also be found in a related condition (lewy body disease, diffuse) characterized by dementia in combination with varying degrees of parkinsonism. (adams et al., principles of neurology, 6th ed, p1059, pp1067-75)
• Peroneal Neuropathies-. disease involving the common peroneal nerve or its branches, the deep and superficial peroneal nerves. lesions of the deep peroneal nerve are associated with paralysis of dorsiflexion of the ankle and toes and loss of sensation from the web space between the first and second toe. lesions of the superficial peroneal nerve result in weakness or paralysis of the peroneal muscles (which evert the foot) and loss of sensation over the dorsal and lateral surface of the leg. traumatic injury to the common peroneal nerve near the head of the fibula is a relatively common cause of this condition. (from joynt, clinical neurology, 1995, ch51, p31)
• Poliomyelitis-. an acute infectious disease of humans, particularly children, caused by any of three serotypes of human poliovirus (poliovirus). usually the infection is limited to the gastrointestinal tract and nasopharynx, and is often asymptomatic. the central nervous system, primarily the spinal cord, may be affected, leading to rapidly progressive paralysis, coarse fasciculation and hyporeflexia. motor neurons are primarily affected. encephalitis may also occur. the virus replicates in the nervous system, and may cause significant neuronal loss, most notably in the spinal cord. a rare related condition, nonpoliovirus poliomyelitis, may result from infections with nonpoliovirus enteroviruses. (from adams et al., principles of neurology, 6th ed, pp764-5)
• Pseudobulbar Palsy-. a syndrome characterized by dysarthria, dysphagia, dysphonia, impairment of voluntary movements of tongue and facial muscles, and emotional lability. this condition is caused by diseases that affect the motor fibers that travel from the cerebral cortex to the lower brain stem (i.e., corticobulbar tracts); including multiple sclerosis; motor neuron disease; and cerebrovascular disorders. (from adams et al., principles of neurology, 6th ed, p489)
• Pupil Disorders-. conditions which affect the structure or function of the pupil of the eye, including disorders of innervation to the pupillary constrictor or dilator muscles, and disorders of pupillary reflexes.
• Quadriplegia-. severe or complete loss of motor function in all four limbs which may result from brain diseases; spinal cord diseases; peripheral nervous system diseases; neuromuscular diseases; or rarely muscular diseases. the locked-in syndrome is characterized by quadriplegia in combination with cranial muscle paralysis. consciousness is spared and the only retained voluntary motor activity may be limited eye movements. this condition is usually caused by a lesion in the upper brain stem which injures the descending cortico-spinal and cortico-bulbar tracts.
• Radial Neuropathy-. disease involving the radial nerve. clinical features include weakness of elbow extension, elbow flexion, supination of the forearm, wrist and finger extension, and thumb abduction. sensation may be impaired over regions of the dorsal forearm. common sites of compression or traumatic injury include the axilla and radial groove of the humerus.
• Respiratory Paralysis-. complete or severe weakness of the muscles of respiration. this condition may be associated with motor neuron diseases; peripheral nerve diseases; neuromuscular junction diseases; spinal cord diseases; injury to the phrenic nerve; and other disorders.
• Sleep Paralysis-. a common condition characterized by transient partial or total paralysis of skeletal muscles and areflexia that occurs upon awakening from sleep or less often while falling asleep. stimuli such as touch or sound may terminate the episode, which usually has a duration of seconds to minutes. this condition may occur in normal subjects or be associated with narcolepsy; cataplexy; and hypnagogic hallucinations. the pathophysiology of this condition is closely related to the normal hypotonia that occur during rem sleep. (from adv neurol 1995;67:245-271)
• Tick Paralysis-. paralysis caused by a neurotropic toxin secreted by the salivary glands of ticks.
• Vocal Cord Paralysis-. congenital or acquired paralysis of one or both vocal cords. this condition is caused by defects in the central nervous system, the vagus nerve and branches of laryngeal nerves. common symptoms are voice disorders including hoarseness or aphonia.
• Amyotrophic Lateral Sclerosis-. a degenerative disorder affecting upper motor neurons in the brain and lower motor neurons in the brain stem and spinal cord. disease onset is usually after the age of 50 and the process is usually fatal within 3 to 6 years. clinical manifestations include progressive weakness, atrophy, fasciculation, hyperreflexia, dysarthria, dysphagia, and eventual paralysis of respiratory function. pathologic features include the replacement of motor neurons with fibrous astrocytes and atrophy of anterior spinal nerve roots and corticospinal tracts. (from adams et al., principles of neurology, 6th ed, pp1089-94)
• Myotonia-. prolonged failure of muscle relaxation after contraction. this may occur after voluntary contractions, muscle percussion, or electrical stimulation of the muscle. myotonia is a characteristic feature of myotonic disorders.
• Thyrotoxicosis-. a hypermetabolic syndrome caused by excess thyroid hormones which may come from endogenous or exogenous sources. the endogenous source of hormone may be thyroid hyperplasia; thyroid neoplasms; or hormone-producing extrathyroidal tissue. thyrotoxicosis is characterized by nervousness; tachycardia; fatigue; weight loss; heat intolerance; and excessive sweating.

Paralysis

Paralysis is the loss of muscle function in part of your body. It happens when something goes wrong with the way messages pass between your brain and muscles. Paralysis can be complete or partial. It can occur on one or both sides of your body. It can also occur in just one area, or it can be widespread. Paralysis of the lower half of your body, including both legs, is called paraplegia. Paralysis of the arms and legs is quadriplegia.

Most paralysis is due to strokes or injuries such as spinal cord injury or a broken neck. Other causes of paralysis include:

• Nerve diseases such as amyotrophic lateral sclerosis
• Autoimmune diseases such as Guillain-Barre syndrome
• Bell's palsy, which affects muscles in the face

Polio used to be a cause of paralysis, but polio no longer occurs in the U.S.
